Journal articles on the topic 'Paranoia : Psychosis : Anxiety cognitive models'

Cognitive behavioral models of psychosis assert the notion of cognitive mediation, in which threat-oriented subjective misinterpretations of anomalous experiences lead to increased levels of emotional distress. Thus, paranoid appraisals of auditory hallucinations often result in hypervigilance and associated anxiety. The prevalence of diagnostic comorbidity between psychosis and anxiety disorders has been shown to be considerable. Among the evidence-based psychological treatments for complex mental ill-health, Cognitive Behavioral Therapy for psychosis (CBTp) has been supported with particularly promising research outcomes. Yet, despite such encouraging empirical data, the treatment provision often remains insufficient, predominantly among individuals with more acute presentations. Likewise, literature demonstrating the actual utilization of CBTp with complex psychoses appears above all relevant to the daily clinical practice in the specialism of severe mental ill-health. This methodologically rigorous case study describes a successful implementation of CBTp undertaken with a socially withdrawn individual diagnosed with paranoid schizophrenia and comorbid agoraphobic anxiety disorder. The intervention focused on cognitive restructuring of paranoid appraisals of voices and graded behavioral exposure to anxiety-inducing stimuli. Standardized measurement, behavior frequency sampling, and subjective data were utilized to evaluate the outcomes, indicating a considerable reduction in both paranoia and associated anxiety, and an overall improvement in the client’s behavioral and interpersonal functioning. The article highlights the importance of direct intellectual engagement with the content of paranoia, alongside methodically facilitated graded behavioral exposure and response prevention in the treatment of severe, socially debilitating psychoses with comorbid mood disorders.

Background:Current clinical models emphasize certain cognitive processes in the maintenance of distressing paranoia. While a number of these processes have been examined in detail, the role of strategic cognition and self-focused attention remain under-researched.Aims:This study examined the deployment of cognitive strategies and self-focused attention in people with non-clinical paranoia.Method:An experimental design was used to examine the impact of a threat activation task on these processes, in participants with high and low non-clinical paranoia. Twenty-eight people were recruited to each group, and completed measures of anxiety, paranoid cognition, strategic cognition and self-focused attention.Results:The threat activation task was effective in increasing anxiety in people with high and low non-clinical paranoia. The high paranoia group experienced more paranoid cognitions following threat activation. This group also reported greater use of thought suppression, punishment and worry, and less use of social control strategies when under threat. No differences were found between the groups on measures of self-focused attention.Conclusions:This study shows that the threat activation task increased anxiety in people with high non-clinical paranoia, leading to increased paranoid thinking. The use of strategic cognition following threat activation varied dependent on level of non-clinical paranoia. If these differences are replicated in clinical groups, the strategies may be implicated in the maintenance of distressing psychosis, and may therefore be a valuable target for therapeutic intervention.

The prevalence of diagnostic comorbidity between psychosis and anxiety disorders has been found to be considerable. Cognitive models of psychosis suggest that anxiety does not arise directly from positive symptoms of schizophrenia but rather from an individual interpretation of such experiences. In the United Kingdom, cognitive-behavioural therapy for psychosis (CBTp) has been recommended within clinical guidelines as a psychological treatment of choice for those diagnosed with schizophrenia. However, despite empirical evidence supporting CBTp, the treatment provision remains infrequent and not routinely available. This case describes a successful implementation of CBTp. Sixteen sessions were delivered to a 40-year-old male with diagnoses of paranoid schizophrenia and comorbid anxiety, focusing primarily on cognitive restructuring of paranoid appraisals of auditory hallucinations and behavioural experiments employed progressively via graded exposure to anxiety-inducing stimuli. Standardised measurements, behavioural frequency sampling, and subjective data indicated a considerable reduction in both paranoia and anxiety. Also, the client’s psychosocial functioning improved substantially. This report indicates that the treatment may help those with experiences of psychosis and comorbid anxiety reach a significant improvement in their quality of life and offers an encouraging and innovative perspective on direct engagement with the content of paranoia and voices at the onset of therapy.

Background:There is strong evidence to suggest that anxiety is associated with paranoia in clinical and non-clinical samples. However, no research to date has directly manipulated anxiety to investigate if state-anxiety has a causal role in state-paranoia in clinical populations.Aims:To investigate whether an anxious-mood induction leads to greater paranoia than a neutral-mood induction in people experiencing psychosis and paranoia and, if so, whether this is predicted by anxiety over and above other variables.Method:22 participants with a psychosis-spectrum diagnosis took part in a two condition cross-over experimental design. Participants underwent a neutral-mood and an anxious-mood induction with levels of state-anxiety, state-affect and state-paranoia being measured before and after each condition.Results:State-paranoia was significantly higher after the anxious condition compared with the neutral condition. State-anxiety and negative-affect were significant predictors of levels of state-paranoia after the anxious condition. When both predictors were included in a regression model, only negative-affect was a significant predictor of state-paranoia after the anxious condition. There were a number of methodological limitations.Conclusions:State-anxiety and negative-affect may both be involved in the maintenance of paranoia in clinical populations, as predicted by cognitive models. Negative-affect may be the strongest predictor of state-paranoia in clinical populations. Reasons for this are discussed, as well as the implications. Interventions that seek to reduce negative state-affect may be beneficial in managing state-paranoia. Further research is warranted to explore the suggested clinical and theoretical implications of these findings.

Despite extensive needs, interventions for parents with psychosis are rarely offered, poorly described, and vary between offering instrumental and emotional support. To improve the design of interventions offered to families with parental psychosis, more knowledge is needed. The aim of this study was to gain knowledge about mental health professionals’ perceptions of parenting by patients with psychosis. Eleven mental health professionals educated in family interventions were interviewed using a semi-structured interview guide and the material underwent inductive thematic analysis. Results showed that the professionals described the patients parenting as characterized by difficulties in providing security and predictability, taking part in and organizing family life, and to focus on the child’s needs. The difficulties were described as related to specific symptoms such as voice hearing, cognitive impairments, anxiety, and paranoia. As a vast amount of research stresses the psychosocial basis of psychosis and the interpersonal causes of its symptoms, parenting difficulties in people with psychosis could benefit from being addressed from a relational perspective. Accordingly, parents with psychosis should be offered interventions that enable them to create positive parental role models, develop reflective functioning, and identify situations in which their symptoms might hinder positive parenting. Many of these needs are unmet by interventions offered in adult psychosis services today.

BackgroundVirtual reality provides a means of studying paranoid thinking in controlled laboratory conditions. However, this method has not been used with a clinical groupAimsTo establish the feasibility and safety of using virtual reality methodology in people with an at-risk mental state and to investigate the applicability of a cognitive model of paranoia to this groupMethodTwenty-one participants with an at-risk mental state were assessed before and after entering a virtual reality environment depicting the inside of an underground trainResultsVirtual reality did not raise levels of distress at the time of testing or cause adverse experiences over the subsequent week. Individuals attributed mental states to virtual reality characters including hostile intent. Persecutory ideation in virtual reality was predicted by higher levels of trait paranoia, anxiety, stress, immersion in virtual reality, perseveration and interpersonal sensitivityConclusionsVirtual reality is an acceptable experimental technique for use with individuals with at-risk mental states. Paranoia in virtual reality was understandable in terms of the cognitive model of persecutory delusions

BackgroundParanoia is one of the commonest symptoms of psychosis but has rarely been studied in a population at risk of developing psychosis. Based on existing theoretical models, including the proposed distinction between ‘poor me’ and ‘bad me’ paranoia, we aimed to test specific predictions about associations between negative cognition, metacognitive beliefs and negative emotions and paranoid ideation and the belief that persecution is deserved (deservedness).MethodWe used data from 117 participants from the Early Detection and Intervention Evaluation for people at risk of psychosis (EDIE-2) trial of cognitive–behaviour therapy, comparing them with samples of psychiatric in-patients and healthy students from a previous study. Multi-level modelling was utilized to examine predictors of both paranoia and deservedness, withpost-hocplanned comparisons conducted to test whether person-level predictor variables were associated differentially with paranoia or with deservedness.ResultsOur sample of at-risk mental state participants was not as paranoid, but reported higher levels of ‘bad-me’ deservedness, compared with psychiatric in-patients. We found several predictors of paranoia and deservedness. Negative beliefs about self were related to deservedness but not paranoia, whereas negative beliefs about others were positively related to paranoia but negatively with deservedness. Both depression and negative metacognitive beliefs about paranoid thinking were specifically related to paranoia but not deservedness.ConclusionsThis study provides evidence for the role of negative cognition, metacognition and negative affect in the development of paranoid beliefs, which has implications for psychological interventions and our understanding of psychosis.

Delusional beliefs are characteristic of psychosis and, of the delusions, the paranoid delusion is the single most common type associated with psychosis. The many years of research focused on neurocognition in schizophrenia, using standardized neurocognitive tests, have failed to find conclusive cognitive deficits in relation to positive symptoms. However, UK-based psychological research has identified sociocognitive anomalies in relation to paranoid thinking in the form of theory of mind (ToM), causal reasoning and threat-related processing anomalies. Drawing from recent neuroscientific research on the default mode network, this paper asserts that the common theme running through the psychological tests that are sensitive to the cognitive impairment of paranoia is the need to cognitively project the self through time, referred to as mental time travel. Such an understanding of the cognitive roots of paranoid ideation provides a synthesis between psychological and biological accounts of psychosis while also retaining the powerful argument that understanding abnormal thinking must start with models of normal cognition. This is the core theme running through the cognitive psychological literature of psychiatric disorders that enables research from this area to inform psychological therapy.

AbstractObjectiveTo examine the interaction of specific anxiety subtypes and psychosis.IntroductionAccumulating evidence suggests that anxiety and its disorders play a significant role in patients with schizophrenia, but few studies have examined multiple types of anxiety and how they interact with different symptoms of schizophrenia.MethodsThirty-two patients diagnosed with schizophrenia or schizoaffective disorder were assessed through self-report measures and interviewer rating scales to examine symptoms of psychosis and anxiety.ResultsA majority of patients (62%) were diagnosed with at least one comorbid anxiety disorder. Obsessive-compulsive symptoms and social anxiety symptoms were related to positive symptoms, bizarre behavior, and quality of life (QOL). Furthermore, panic and social anxiety were related to suspiciousness/paranoia. No consistent relationship was found with negative symptoms. Finally, severity of anxiety disorders was negatively correlated with the severity of formal thought disorder.DiscussionThis is one of the first studies to simultaneously examine the interrelationships of different types of anxiety symptoms and psychotic symptoms. The present findings are consistent with the studies that have suggested relationships between panic and paranoia and comorbid anxiety disorders and impaired QOL. These data suggest that further research into anxiety in schizophrenia, including the cognitive and neurobiological correlates, may help elucidate the mechanisms involved in the manifestation of these psychopathologiesConclusionAnxiety disorders are common in patients with schizophrenia. The presence of such symptoms may influence the presence of core psychotic symptoms and QOL. More information is needed in terms of the relationship between treatment of these symptoms and changes in psychotic symptoms and/or relapse prevention.

Background. Traditional instruments that measure self-esteem may not relate directly to the schema construct as outlined in recent cognitive models. The Brief Core Schema Scales (BCSS) aim to provide a theoretically coherent self-report assessment of schemata concerning self and others in psychosis. The scales assess four dimensions of self and other evaluation: negative-self, positive-self, negative-other, positive-other.Method. We analysed the psychometric properties of the BCSS using a sample of 754 students recruited by email and 252 people with psychosis recruited as part of a trial of cognitive therapy. We report the internal consistency, stability and the factor structure of the scale, and the association of the BCSS with measures of self-esteem and with symptoms of paranoia and grandiosity.Results. The BCSS have good psychometric properties and have more independence from mood than the Rosenberg Self-Esteem Schedule. People with chronic psychosis reported extreme negative evaluations of both self and others on these scales, but their levels of self-esteem and positive evaluations of self and others were similar to the student sample.Conclusions. Extreme negative evaluations of self and others appear to be characteristic of the appraisals of people with chronic psychosis, and are associated with symptoms of grandiosity and paranoia in the non-clinical population. The BCSS may provide a more useful measure of schemata about self and others than traditional measures of self-esteem.

AbstractBackgroundThe cognitive process of worry, which keeps negative thoughts in mind and elaborates the content, contributes to the occurrence of many mental health disorders. Our principal aim was to develop a straightforward measure of general problematic worry suitable for research and clinical treatment. Our secondary aim was to develop a measure of problematic worry specifically concerning paranoid fears.MethodsAn item pool concerning worry in the past month was evaluated in 250 non-clinical individuals and 50 patients with psychosis in a worry treatment trial. Exploratory factor analysis and item response theory (IRT) informed the selection of scale items. IRT analyses were repeated with the scales administered to 273 non-clinical individuals, 79 patients with psychosis and 93 patients with social anxiety disorder. Other clinical measures were administered to assess concurrent validity. Test-retest reliability was assessed with 75 participants. Sensitivity to change was assessed with 43 patients with psychosis.ResultsA 10-item general worry scale (Dunn Worry Questionnaire; DWQ) and a five-item paranoia worry scale (Paranoia Worries Questionnaire; PWQ) were developed. All items were highly discriminative (DWQ a = 1.98–5.03; PWQ a = 4.10–10.7), indicating small increases in latent worry lead to a high probability of item endorsement. The DWQ was highly informative across a wide range of the worry distribution, whilst the PWQ had greatest precision at clinical levels of paranoia worry. The scales demonstrated excellent internal reliability, test-retest reliability, concurrent validity and sensitivity to change.ConclusionsThe new measures of general problematic worry and worry about paranoid fears have excellent psychometric properties.

Abstract Background Social anxiety disorder (SAD) is common in people experiencing psychosis, with a pooled prevalence rate of 21% (16%-26%). It is evidenced that the factors maintaining SAD in psychosis is inconclusive, and more work is needed to understand the causal and maintenance mechanisms in order to develop more targeted therapies. So far, no previous systematic review has investigated factors that maintain SAD in psychosis. An integrated analysis of key factors from the literature combined with existing therapeutic knowledge (e.g. Cognitive Behavioural Therapy) could positively impact clinical practice. We therefore aimed to identify candidate factors maintaining SAD in psychosis, along with the factors related social anxiety in those with psychotic experiences. Methods MEDLINE, Embase, CENTRAL and PsycINFO databases were searched on 31 October 2018. Which search terms used for Population were ((psychosis) or (psychotic) or (schizophreni*) or (schizoaffective) or (delusion*) or (paranoi*) or (clinical high risk*) or (ultra high risk*) or (attenuated) or (at risk mental state*) or (recent onset) or (first episode psycho*) or (early psycho*)), and for Outcome were ((social anxi*) or (social phob*)). According to included studies are highly heterogeneous data, then we planned a narrative synthesis. The methodological quality and risk of bias of included studies were assessed using the Mixed Methods Appraisal Tool (MMAT) - Version 2011. Results Of 43 out of 3982 studied were eligible for narrative synthesis. The studies included cross-sectional (33 studies), prospective (7 studies), randomised controlled trials (1 studies), a non-randomised clinical trial (1 study) and a qualitative study (1 study). Total participants were 11,825; the majority were drawn from the general population (N=8680), followed by psychosis samples (N=2512) and those at high risk of psychosis (N=633). General quality of the literature (41 studies) were determined as good to high quality. Regarding the objective, the psychological factors that may play a role in the maintenance of SAD in psychosis were identified. The major factors were cognitive factors; here are stigma, low self-esteem, shame, low social rank, negative thoughts, hopelessness and post-event processing, respectively. Metacognitive factors were found in different factors: mentalization, theory of mind, metacognition and reasoning bias. Few studies examined safety behaviours factor. Other maintenance factors were adult attachment, empathy, intolerance of uncertainty and coping style. We also identified the factors related social anxiety in psychotic context. There were poorer quality of life (QoL), poorer daily functioning with poorer premorbid functioning, poorer well-being, poorer family functions, more traumatic events, personality problems, more anomalous experiences, impaired executive function, suicidality, subclinical paranoia, persecutory threat and anhedonia. Discussion The results of this review have raised three main factors: cognitive, metacognitive and behavioural factors. A high number of candidate cognitive factors were identified, and stigma is the most commonly maintenance factors. Poor QoL and daily function were common impairments associated with social anxiety. The evidence of metacognitive and behavioural factors is limited and needed more research attention. Due to lack of research examining factors across cultures in social anxiety and psychosis, future research required empirical evidence for cross-cultural aspects. Limitations are the major studies were cross-sectional, which is far less conclusive of causation; and the heterogeneous data which prevented us from applying meta-analysis.

It has long been known that cannabis can elicit an acute psychotic reaction. Recent work shows that, of the 60 cannabinoid molecules in the plant, delta-9-tetrahydrocannibinol is responsible for the central effects of cannabis. Here we aimed to investigate, in more detail, the psychological effects of synthetic intravenous THC in healthy subjects. Over 2 experimental sessions, participants (N=22) were administered 2.5mg IV THC or placebo under randomised, double-blind conditions. Psychological reactions were assessed using standard rating instruments and a battery of cognitive tests was completed.Following THC, there was a significant increase in self-rated and observer-rated positive psychotic symptoms which were highly correlated (r=0.62, p=0.001).Phenomena centered on de-synchronisation of self-agency (ipseity disturbance) and hypersalience/paranoia. Participants also reported a significant increase in negative symptomatology under THC conditions, which was not explained by sedation. Finally, working memory/executive functioning was markedly and consistently impaired by THC.Here we provide further evidence that THC can elicit an acute psychotic reaction in a proportion of healthy subjects. Acute THC-psychosis elicits positive, negative and cognitive symptoms. Compared with other drug models THC recreates symptomatology across 3 major dimensions of schizophrenic psychosis without sedation/clouding of consciousness. Here we also present preliminary evidence that the molecule cannabidiol (CBD) inhibits THC-elicited positive symptoms. Current work in our laboratory is exploring the underlying mechanisms.

AbstractExperience sampling method (ESM) studies have found an association between daily stress and paranoid symptoms, but it is uncertain whether these findings generalize to physiological indicators of stress. Moreover, the temporality of the association and its moderating factors require further research. Here, we investigate whether physiological and self-rated daily stress predict subsequent paranoid symptoms and analyze the role of emotion regulation as a putative moderator. We applied ESM during 24 h to repeatedly assess heart rate, self-rated stress, and subclinical paranoia in a sample of 67 psychosis-prone individuals as measured with Community Assessment for Psychotic Experiences (CAPE). Adaptive and maladaptive emotion regulation was assessed at baseline with the Emotion Regulation Skills Questionnaire (ERSQ-ES) and the Cognitive Emotion Regulation Questionnaire (CERQ). Linear mixed models were used to analyze the data. Heart rate (b = 0.004, p < 0.05) and self-rated stress (b = 0.238, p < 0.001) predicted subsequent paranoia. The reverse effect, paranoia as a predictor of subsequent heart rate (b = 0.230, p = 0.615) or self-rated stress (b = –0.009, p = 0.751) was non-significant. Maladaptive emotion regulation was a significant predictor of paranoia (b = 0.740, p < 0.01) and moderated the path from self-rated stress to paranoia (b = 0.188, p < 0.05) but not the path from heart rate to paranoia (b = 0.005, p = 0.09). Our findings suggest a one-way temporal link between daily stress and paranoia and highlight the importance of emotion regulation as a vulnerability factor relevant to this process.

IntroductionMany patients with psychosis experience everyday social situations as anxiety-provoking. The fears can arise, for example, from paranoia, hallucinations, social anxiety or negative-self beliefs. The fears lead patients to withdraw from activities, and this isolation leads to a cycle of worsening physical and mental health. Breaking this cycle requires highly active treatment directly in the troubling situations so that patients learn that they can safely and confidently enter them. However patients with psychosis seldom receive such life-changing interventions. To solve this problem we have developed an automated psychological treatment delivered in virtual reality (VR). It allows patients to experience computer simulations of the situations that they find anxiety-provoking. A virtual coach guides patients, using cognitive techniques, in how to overcome their fears. Patients are willing to enter VR simulations of anxiety-provoking situations because they know the simulations are not real, but the learning made transfers to the real world.Methods and analysis432 patients with psychosis and anxious avoidance of social situations will be recruited from National Health Service (NHS) secondary care services. In the gameChange trial, they will be randomised (1:1) to the six-session VR cognitive treatment added to treatment as usual or treatment as usual alone. Assessments will be conducted at 0, 6 (post-treatment) and 26 weeks by a researcher blind to allocation. The primary outcome is avoidance and distress in real-life situations, using a behavioural assessment task, at 6 weeks. The secondary outcomes are psychiatric symptoms, activity levels and quality of life. All main analyses will be intention-to-treat. Moderation and mediation will be tested. An economic evaluation will be conducted.Ethics and disseminationThe trial has received ethical approval from the NHS South Central - Oxford B Research Ethics Committee (19/SC/0075). A key output will be a high-quality automated VR treatment for patients to overcome anxious avoidance of social situations.Trial registration numberISRCTN17308399.

BackgroundAlthough risk for psychosis in velocardiofacial (22q11.2 deletion) syndrome (VCFS) is well established, the cognitive and familial factors that moderate that risk are poorly understood.MethodA total of 75 youth with VCFS were assessed at three time points, at 3-year intervals. Time 1 (T1) psychiatric risk was assessed with the Behavior Assessment System for Children (BASC). Data reduction of BASC scores yielded avoidance–anxiety and dysregulation factors. Time 2 (T2) neuropsychological and family function and time 3 (T3) prodromal/overt psychosis were assessed. Poisson regression models tested associations between T3 positive prodromal symptoms/overt psychosis and T1 psychiatric risk, T2 cognitive and familial factors, and their interactions.ResultsT1 avoidance–anxiety ratings predicted T3 prodromal/overt psychosis. T2 verbal learning scores moderated this association, such that individuals with low avoidance–anxiety scores and stronger verbal learning skills were the least likely to demonstrate prodromal/overt psychosis at T3. Low scores on a T2 visual vigilance task also predicted T3 prodromal/overt psychosis, independently of the effect of T1 avoidance–anxiety scores. T1 dysregulation scores did not predict T3 prodromal/overt psychosis in a linear manner. Instead, the association between dysregulation and prodromal/overt psychosis was amplified by T2 levels of family organization, such that individuals with low dysregulation scores and low family organization scores were the most likely to exhibit T3 prodromal/overt psychosis.ConclusionsSignificant moderators of psychiatric risk in VCFS include verbal learning skills as well as levels of family organization, carrying implications for early identification and preventative treatment of youth with VCFS at highest risk for psychosis.

AbstractObjectives: Three patients presenting with a first episode of psychosis each had a past history of social phobia. We sought to explore the literature on the co-occurrence of these disorders and investigate three hypotheses to explain this: (1) the chance co-occurrence of two illnesses with distinct aetiologies; (2) two clinical presentations reflecting different points on the same spectrum of illness; and (3) two distinct disorders representing different end points resulting from the same aetiology.Method: A literature review of Embase, PubMed and Psych Lit was performed.Results: We found no reports on social phobia preexisting an episode of psychosis, and prevalence studies indicate that their chance co-occurrence is extremely unlikely. Psychological explanations for co-occurrence include attributional theories, and theories related to cognitive biases and loss of self-esteem.Conclusion: There is a phenomenological overlap between social phobia and paranoia but the two concepts should and can be distinguished. Epidemiological studies indicate that their chance occurrence as two unrelated disorders is unlikely. Most people with one of these disorders do not develop the other and hypothesis (2) is also unlikely. There is increasing speculation that anxiety, and in particular social phobic symptoms have a central role in the development of psychotic symptoms. The greatest evidence was found to support hypothesis (3).However, it seems more likely that social phobia and psychosis, rather than representing manifestations of the same illness, instead are implicated in a complex interaction where symptoms which characterise social phobia and psychosis, have the capacity to affect, alter and possibly provoke each other. The recognition and treatment of co-occurring anxiety disorders, especially social phobia with psychosis, may have an important impact on prognosis and quality of life.

Abstract. Considering several etiologic, therapeutic, and comorbidity-related factors, a psychosis continuum model has been proposed for the understanding and treatment of psychotic disorders. Within the new emerging treatment approaches, Contextual Cognitive-Behavioral Therapies (CCBT) seem to hold promise for the psychosis continuum. However, considering their novelty for this specific population, the quality of efficacy evidence remains unclear. Objective: To examine, critically analyze, and summarize the results from studies based on therapeutic models within the CCBT approach (Mindfulness and Acceptance-based interventions, Compassion-Focused Therapy, Dialectical Behavior Therapy, and Metacognitive Therapy) for patients with a diagnosis within the psychosis continuum (schizophrenia, schizoaffective disorder, bipolar disorder). Methods: Three leading electronic databases (MEDLINE/PUBMED; PsycINFO; Cochrane Library), a grey literature database (OpenGrey), and registered clinical trials (ClinicalTrials.Gov) were searched using combinations of key terms regarding the CCBT models and the diagnosis considered. Reference lists of the relevant studies and reviews were searched. Only Randomized Controlled Trials (RCTs) were included. The “Cochrane Risk of Bias Assessment Tool” was used for quality assessment. Results: A total of 17 articles were included. This review was based on a majority of unclear or low risk of bias studies. Benefits regarding clinical variables such as psychotic symptoms, anxiety and depression, functioning or quality of life were found. Conclusion: Overall the studies supported some benefits of CCBT approaches for the psychosis continuum. The conceptual perspective on treatment has changed, nevertheless the outcomes assessed are still symptom-focused and there is still need for improvement. Methodological considerations and future directions are presented.

BackgroundThere have been recent advances in the identification of people at high risk of psychosis and psychological treatments have shown promise for preventionAimsTo compare the longitudinal course of psychotic experiences and emotional dysfunction in high-risk participants receiving cognitive therapy with those receiving treatment as usualMethodData from a recent randomised controlled trial of cognitive therapy for people at risk of developing psychosis were utilised to examine three different statistical models that were based on 432 measurements of psychotic experiences and 421 of emotional dysfunction (anxiety–depression) contributed by 57 participants across the 13 measurement occasions (monthly monitoring for a year)ResultsPsychotic experiences and emotional dysfunction were correlated and decreased significantly over the course of the study, with most improvement in the early months. The reduction in positive symptoms, but not emotional dysfunction, was enhanced by allocation to cognitive therapyConclusionsPsychotic experiences and emotional dysfunction appear to interact in people at risk of developing psychosis. There appears to be a specific benefit of cognitive therapy

AbstractCognitive theory posits that core beliefs play an active role in developing and maintaining symptoms of depression, anxiety, and psychosis. This study sought to comprehensively examine core beliefs, their dimensionality, and their relationships to depression, anxiety, and attenuated psychotic symptoms in two groups of community youth: a group at ultrahigh risk for psychosis (UHR; n = 73, M age = 18.7) and a matched healthy comparison group (HC; n = 73, M age = 18.1). UHR youth reported significantly more negative beliefs about self and others, and significantly less positive beliefs about self and others. HC youth rarely endorsed negative self-beliefs. Exploratory factor analyses found that HC negative self-beliefs did not cohere as a single factor. We hypothesized specific links between core beliefs and symptoms based on cognitive models of each disorder, and tested these links through regression analyses. The results in the HC group were consistent with the proposed models of depression and anxiety. The results in the UHR group were consistent with proposed models of depression and negative psychotic symptoms, somewhat consistent with a proposed model of positive psychotic symptoms, and not at all consistent with a proposed model of anxiety. These findings add to a growing developmental literature on core beliefs and psychopathology, with important clinical implications.

Background: Synthetic cannabinoids are, typically, full agonists at the cannabinoid CB1 receptor, and therefore considerably more potent than natural cannabis and may have correspondingly more serious psychological effects. Despite government sanctions against their production they continue to be available in ever-increasing varieties over the Internet. The psychological consequences of synthetic cannabinoid use are relatively unknown. Aim: The purpose of this study was to synthesise the available research on the psychological consequences of synthetic cannabinoid use. Method: A literature search of three databases was conducted in February 2018, including the following keywords: Spice, synthetic cannabis, cognition, affect, behaviour, psychosis, depression and anxiety. Results: Seventeen studies involving a variety of participants were eligible for inclusion: one controlled administration study, seven cross-sectional studies, five Internet surveys and four qualitative studies. The controlled administration study showed that, compared to placebo, synthetic cannabinoids acutely affected some aspects of cognitive functioning and subjective psychological ratings. Non-controlled, cross-sectional studies generally showed that synthetic cannabinoid users had lower performance on cognitive tasks and showed elevated symptomatology (e.g. paranoia) compared to both natural cannabis and non-cannabis users. Methodological limitations were noted across different study designs. There is limited research on how doses, frequency or type of synthetic cannabinoid influence outcomes. Conclusions: Acute synthetic cannabinoid use can result in a range of psychological outcomes and, when non-intoxicated, synthetic cannabinoid users appear to differ from natural cannabis and non-users on various affective and cognitive domains. As synthetic cannabinoid use is increasing in at-risk populations there is an urgent need for more and better research to inform users, professionals and policymakers.

Background: The outbreak of Corona Virus Disease 2019 (COVID-19) might affect the psychological health of population, especially medical workers. We aimed to investigate the impact of the COVID-19 pandemic on emotional and cognitive responses and behavioral coping among Chinese residents. Methods: An online investigation was run from 5 February to 25 February 2020, which recruited a total of 616 Chinese residents. Self-designed questionnaires were used to collect demographic information, epidemic knowledge and prevention of COVID-19 and characteristics of medical workers. The emotional and cognitive responses were assessed via the Symptom Check List-30 (SCL-30) and Yale–Brown Obsessive Compulsive Scale (Y-BOCS). Behavioral coping was assessed via Simplified Coping Style Questionnaire (SCSQ). Results: In total, 131 (21.3%) medical workers and 485 (78.7%) members of the general public completed the structured online survey. The structural equation models showed that emotional response interacted with cognitive response, and both emotional response and cognitive response affected the behavioral coping. Multivariate regression showed that positive coping enhanced emotional and cognitive responses, while negative coping reduced emotional and cognitive responses. The emotional response (depression, anxiety and photic anxiety) scores of the participants were higher than the norm (all p < 0.001); in particular, the panic scores of members of the general public were higher than those of medical workers (p < 0.05), as well as the cognitive response (paranoia and compulsion). Both positive and negative coping scores of the participants were lower than the norm (p < 0.001), and the general public had higher negative coping than medical workers (p < 0.05). Conclusion: During the preliminary stage of COVID-19, our study confirmed the significance of emotional and cognitive responses, which were associated with behavioral coping and significantly influenced the medical workers and the general public’s cognition and level of public health emergency preparedness. These results emphasize the importance of psychological health at times of widespread crisis.

IntroductionVan Os et al. (2009) have proposed a Proneness-Persistence-lmpairment model to explain the psychosis continuum, and cognitive models of psychosis have suggested that appraisals of anomalous experiences may be key in determining ‘need for care’.ObjectivesThe present study investigated the interaction between appraisals and safety behaviours in the maintenance of impairing psychotic symptoms.AimsIt was predicted that individuals with psychotic symptoms without a need for care would display fewer threat appraisals and safety behaviours than their clinical counterparts, and that these variables would predict distress.MethodsThe study recruited people with persistent psychotic experiences but who had no-need-for-care (Persistence group; n = 39) and individuals diagnosed with a psychotic disorder who were receiving current treatment (Impairment group; n = 28). The participants were assessed on semi-structured interviews of appraisals and safety behaviours in relation to their psychotic experiences and on anxiety and depression questionnaires.ResultsBoth groups had similar levels of psychotic symptoms in the last month, including first rank symptoms. However there was a large significant difference between Impairment and Persistence groups in threat appraisals and safety behaviours, with the Persistence group reporting higher levels of both. A mediation analysis found that threat appraisals mediated the relationship between safety behaviours and anomaly-related distress, suggesting that threat appraisals may maintain anomaly-related distress, a defining feature of Impairment status.ConclusionsThese data provide support for the cognitive model of psychosis, with threat appraisals potentially playing a major role in the transition from non-clinical anomalous experiences to clinical psychotic status.

AbstractBackgroundIn cognitive models of adult psychosis, schematic beliefs about the self and others are important vulnerability and maintaining factors, and are therefore targets for psychological interventions. Schematic beliefs have not previously been investigated in children with distressing unusual, or psychotic-like, experiences (UEDs). The aim of this study was firstly to investigate whether a measure of schematic beliefs, originally designed for adults with psychosis, was suitable for children; and secondly, to examine the association of childhood schematic beliefs with internalising and externalising problems and with UEDs.MethodSixty-seven children aged 8–14 years, with emotional and behavioural difficulties, completed measures of UEDs, internalising (depression and anxiety), and externalising (conduct and hyperactivity-inattention) problems, together with the Brief Core Schema Scales (BCSS).ResultsThe BCSS was readily completed by participants, and scale psychometric properties were good. Children tended to view themselves and others positively. Internalising and externalising problems and UEDs were all associated with negative schematic beliefs; effect sizes were small to medium.ConclusionsSchematic beliefs in young people can be measured using the BCSS, and negative schematic beliefs are associated with childhood psychopathology and with UEDs. Schematic beliefs may therefore form a useful target in psychological interventions for young people with UEDs.

Abstract Background Psychosis relapses are common, have profound adverse consequences for patients, and are costly to health services. ‘Early signs’ (e.g. anxiety; insomnia) have been used to predict relapse, in the hope of prevention or mitigation, with moderate sensitivity and specificity. Recent studies have provided preliminary prospective evidence that assessing ‘basic symptoms’ (e.g. vivid colour vision; disturbances in expressive speech) in addition to conventional early signs improves relapse prediction. Basic symptoms are assumed to be one of the earliest, most basic subjective expressions of the underlying neurobiological disruption preceding the development of psychosis. There is some empirical evidence from ultra-high risk groups suggesting that basic symptoms do indeed emerge prior to other risk indicators during the prodromal period. However, no studies to date have examined the relative timing of increases in basic symptoms, conventional early signs and psychotic symptoms in individuals with established psychosis. In the current study, we used time-lagged, repeated measures, prospective data to test whether increased basic symptoms would precede increased conventional early signs, and in turn increased psychotic symptoms. Methods Individuals who had experienced a relapse of psychosis within the past year (n=18) were asked to use a smartphone app (‘ExPRESS’) weekly for six months to report early signs, basic symptoms and psychotic symptoms. Participants completed 65% of app assessments over the 6 month follow-up period, providing >200 observations in total. These data were analyzed using mixed effects models to account for clustering within individuals and to allow for missing data. Results App items showed high concurrent validity with researcher-rated psychotic symptoms (ρ range 0.80 to 0.87, p<0.001) and basic symptoms (ICC=0.76, p<0.001) over six months. The results of the mixed effects analyses described above will be presented in full, and their theoretical and clinical implications will be discussed. Discussion We anticipate that the findings of this study will be of theoretical interest. Within the socio-developmental-cognitive model (Howes & Murray, 2014), it would be logical to equate basic symptoms with the initial ‘anomalous experiences’ that are proposed to occur as a result of a disrupted dopamine system. Conventional early signs may then either occur later in the deterioration process laid out in the model or, as a heterogeneous group, may relate to more than one stage of the process. The results of the current study may help to elucidate the place of basic symptoms and conventional early signs within the socio-developmental-cognitive model. The findings may also lend support to the idea that basic symptoms are dopaminergic in origin.

BackgroundPatients with schizophrenia are at increased risk of being victims of violent and non-violent crimes. We have determined how the experience of crime and subjective feelings of safety differ between urban and rural residential areas.MethodWe analysed data from the European Schizophrenia Cohort (EuroSC), a 2-year follow-up study of 1208 patients in the UK, France and Germany. Subjective safety and a history of victimhood were elicited with Lehman's Quality of Life Inventory. Regression models adjusted the effects of living environment for country, education, employment, financial situation, drug and alcohol abuse, criminal arrests and the level of schizophrenic symptoms.ResultsTen per cent of patients were victims of violent and 19% of non-violent crimes. There was no significant relationship between victim status and residential area. However, subjective safety was clearly worse in cities than in rural areas. Aspects of objective and subjective safety were related to different factors: being the victim of violence was most strongly associated with alcohol and drug abuse and with criminal arrests of the patients themselves, whereas impaired subjective safety was most strongly associated with poverty and victimhood experience.ConclusionsAlthough urban living was not associated with increased objective threats to their security, patients did feel more threatened. Such stress and anxiety can be related to concepts of social capital, and may contribute unfavourably to the course of the illness, reflecting the putative role of appraisal in cognitive models of psychosis. Securing patients’ material needs may provide a way to improve subjective safety.

AbstractIt has been reported that borderline personality related characteristics can be observed in children, and that these characteristics are associated with increased risk for the development of borderline personality disorder. It is not clear whether borderline personality related characteristics in children share etiological features with adult borderline personality disorder. We investigated the etiology of borderline personality related characteristics in a longitudinal cohort study of 1,116 pairs of same-sex twins followed from birth through age 12 years. Borderline personality related characteristics measured at age 12 years were highly heritable, were more common in children who had exhibited poor cognitive function, impulsivity, and more behavioral and emotional problems at age 5 years, and co-occurred with symptoms of conduct disorder, depression, anxiety, and psychosis. Exposure to harsh treatment in the family environment through age 10 years predicted borderline personality related characteristics at age 12 years. This association showed evidence of environmental mediation and was stronger among children with a family history of psychiatric illness, consistent with diathesis–stress models of borderline etiology. Results indicate that borderline personality related characteristics in children share etiological features with borderline personality disorder in adults and suggest that inherited and environmental risk factors make independent and interactive contributions to borderline etiology.

Abstract Background Evidence suggests that in individuals with psychosis, paranoia is reduced after trauma-focused therapy (TFT) aimed at comorbid posttraumatic stress disorder (PTSD). Objective To identify mediators of the effect of TFT on paranoia. Method In a multicenter single-blind randomized controlled trial 155 outpatients in treatment for psychosis were allocated to 8 sessions Prolonged Exposure (PE; n = 53), 8 sessions Eye Movement Desensitization and Reprocessing (EMDR) therapy (n = 55), or a waiting-list condition (WL; n = 47) for treatment of comorbid PTSD. Measures were performed on (1) paranoia (GPTS); (2) DSM-IV-TR PTSD symptom clusters (CAPS-IV; ie, intrusions, avoidance, and hyperarousal); (3) negative posttraumatic cognitions (PTCI; ie, negative self posttraumatic cognitions, negative world posttraumatic cognitions and self-blame); (4) depression (BDI-II); and (5) cognitive biases (ie, jumping to conclusion, attention to threat, belief inflexibility, and external attribution), cognitive limitations (ie, social cognition problems and subjective cognitive problems), and safety behaviors (DACOBS). Outcome in terms of symptoms of paranoia (1) and potential mediators (2–5) were evaluated at posttreatment, controlling for baseline scores. Results The effects of TFT on paranoia were primarily mediated by negative self and negative world posttraumatic cognitions, representing almost 70% of the total indirect effect. Safety behaviors and social cognition problems were involved in the second step mediational pathway models. Conclusions Targeting the cognitive dimension of PTSD in TFT in psychosis could be an effective way to influence paranoia, whereas addressing safety behaviors and social cognition problems might enhance the impact of TFT on paranoia.

Abstract Background: Catastrophic cognitive appraisals, similar to those in anxiety disorders, are implicated in depersonalisation, a form of dissociation. No scales exist to measure appraisals of dissociative experiences. Dissociation is common in psychosis. Misinterpretations of dissociative experiences may maintain psychotic symptoms. Therefore, assessing appraisals in this context may be valuable. Aims: The primary aim was to develop a measure of key appraisals of dissociation in psychosis. Secondary aims were to test the relationship between appraisals and psychotic experiences (paranoia and hallucinations), and determine whether appraisals explain additional variance in psychotic symptoms above dissociative symptoms. Method: Fifty items were generated from transcripts of interviews with patients. The measure was developed and psychometrically validated via factor analysis of data from 9902 general population participants and 1026 patients with psychosis. Convergent validity, test–re-test reliability, and internal reliability were assessed. Regression analyses tested relationships with psychotic symptoms. Results: A 13-item single-factor measure was developed. Factor analysis indicated good model fit [χ2(65) = 247.173, comparative fit index (CFI) = 0.960, root mean square error of approximation (RMSEA) = 0.052]. The scale had good convergent validity with a rumination (non-clinical: r = 0.71; clinical: r = 0.73) and dissociation measure (r = 0.81; r = 0.80), high internal consistency (α = 0.93; α = 0.93), and excellent 1-week test–re-test reliability [intraclass correlation (ICC) = 0.90]. It explained variance in psychotic symptoms (paranoia: 36.4%; hallucinations: 35.0%), including additional variance compared with dissociation alone (paranoia: 5.3%; hallucinations: 2.3%). Conclusions: The Cognitive Appraisals of Dissociation in Psychosis (CAD-P) measure is a psychometrically robust scale identifying appraisals of dissociative experiences in psychosis and is associated with the presence of psychotic experiences. It is likely to prove useful for clinical assessment and research.

Abstract Background Difficulties in the ability to adapt beliefs in the face of new information are associated with psychosis and its central symptom – paranoia. As cognitive processes and psychotic symptoms are both known to be sensitive to stress, the present study investigated the exact associations between stress, adapting of beliefs [reversal learning (RL), bias against disconfirmatory evidence (BADE), and jumping to conclusions (JTC)] and paranoia. We hypothesized that paranoia would increase under stress and that difficulties in adapting of beliefs would mediate or moderate the link between stress and paranoia. Furthermore, we hypothesized that the investigated effects would be strongest in the group of individuals diagnosed with a psychotic disorder. Methods We exposed 155 participants (38 diagnosed with a psychotic disorder, 40 individuals with attenuated psychotic symptoms, 39 clinical controls diagnosed with an obsessive-compulsive disorder, and 38 healthy controls) to a control condition and a stress condition, in which we assessed their levels of paranoia and their ability to adapt beliefs. We applied multilevel models to analyze the data. Results Paranoia was higher in the stress condition than in the control condition, b = 1.142, s.e. = 0.338, t(150) = 3.381, p < 0.001. RL, BADE, and JTC did not differ between conditions and did not mediate or moderate the association between stress and paranoia (all ps > 0.05). Conclusions The results support the assumption that stress triggers paranoia. However, the link between stress and paranoia does not seem to be affected by the ability to adapt beliefs.

Abstract Worry is common among individuals with psychosis and has been found to be a causal factor in the development of paranoia. Previous research has shown that a cognitive behavioural therapy protocol targeting worry helps to reduce persecutory delusions and associated distress in a population experiencing longstanding psychotic symptoms. However, there has yet to be a published adaptation of the protocol for individuals experiencing a recent onset of psychosis. The current study aims to examine the feasibility of adapting the worry intervention for recent onset psychosis in a group setting. Six young adults with a recent onset of psychosis, aged 18–32 years, participated in a pilot study of an 8-week group intervention covering cognitive behavioural strategies for managing worry, including worry periods, worry postponement techniques, mindfulness and relaxation, and problem solving. Pre- and post-intervention data were collected on worry, anxiety, depressive symptoms, psychotic symptoms, and perceived recovery from psychosis. In addition, qualitative feedback from group members was gathered during a post-intervention focus group. Feasibility of the group appeared promising, despite high participant attrition. All components of the intervention were successfully implemented, and group members provided positive feedback regarding acceptability of the group. Contrary to prediction, there was not a consistent decrease in worry from pre- to post-intervention. Findings from secondary symptom measures were mixed and may have been related to participants’ subjective experience of the group. Specifically, participants who experienced high levels of group cohesion seemed to benefit more from the intervention. Key learning aims (1) To gain awareness of the gaps in treatment for early psychosis. (2) To understand the role of worry in psychosis. (3) To learn about the feasibility of implementing a group worry intervention for recent onset psychosis. (4) To consider the impact of group cohesion and symptom severity on treatment engagement.

Background Symptoms of serious mental illness are multidimensional and often interact in complex ways. Generative models offer value in elucidating the underlying relationships that characterise these networks of symptoms. Aims In this paper we use generative models to find unique interactions of schizophrenia symptoms as experienced on a moment-by-moment basis. Method Self-reported mood, anxiety and psychosis symptoms, self-reported measurements of sleep quality and social function, cognitive assessment, and smartphone touch screen data from two assessments modelled after the Trail Making A and B tests were collected with a digital phenotyping app for 47 patients in active treatment for schizophrenia over a 90-day period. Patients were retrospectively divided up into various non-exclusive subgroups based on measurements of depression, anxiety, sleep duration, cognition and psychosis symptoms taken in the clinic. Associated transition probabilities for the patient cohort and for the clinical subgroups were calculated using state transitions between adjacent 3-day timesteps of pairwise survey domains. Results The three highest probabilities for associated transitions across all patients were anxiety-inducing mood (0.357, P < 0.001), psychosis-inducing mood (0.276, P < 0.001), and anxiety-inducing poor sleep (0.268, P < 0.001). These transition probabilities were compared against a validation set of 17 patients from a pilot study, and no significant differences were found. Unique symptom networks were found for clinical subgroups. Conclusions Using a generative model using digital phenotyping data, we show that certain symptoms of schizophrenia may play a role in elevating other schizophrenia symptoms in future timesteps. Symptom networks show that it is feasible to create clinically interpretable models that reflect the unique symptom interactions of psychosis-spectrum illness. These results offer a framework for researchers capturing temporal dynamics, for clinicians seeking to move towards preventative care, and for patients to better understand their lived experience.

Anxiety Sensitivity (AS) is a transdiagnostic risk factor involved in the development and maintenance of different psychopathological conditions including anxiety disorders and psychosis. It consists of Physical Concerns (e.g., the belief that palpitations lead to a cardiac arrest), Social Concerns (the belief that observable anxiety reactions will elicit social rejection), and Cognitive Concerns (the belief that cognitive difficulties lead to mental incapacitation). No study investigated whether specific AS dimensions are related to At-Risk Mental States (ARMS). This study compared AS dimensions between young individuals with ARMS, patients after a recently occurred First-Episode Psychosis (FEP) and matched community controls. Based on models of ARMS and previous evidence, it was hypothesized that ARMS individuals have higher physical, social and cognitive concerns than FEP patients and controls. Thirty individuals with ARMS and 30 with FEP and 30 controls recruited from the general population completed the Anxiety Sensitivity Index-3 (ASI-3) and Penn State Worry Questionnaire. ARMS and FEP individuals had higher scores than controls on ASI-3 Cognitive Concerns [F(2,87)= 11.48, p<.001]. Individuals with ARMS had higher ASI-3 Physical Concerns scores than FEP patients [F(2,87)= 5.10, p<.01] and at a marginal significance level than controls. No between-group difference was found on Social Concerns. Higher ASI-3 Physical Concerns scores [B = -.324, Wald’s χ2(1) = 8.29, p < .01] and psychiatric comorbidities [B = -2.726, Wald’s χ2(1) = 9.33, p < .01] were significantly related to ARMS than FEP. Higher ASI-3 Social Concerns scores were related to FEP, despite at a marginal significance level [B =.213, Wald’s χ2(1) = 3.79, p = .052]. Interventions for AS Cognitive/Physical Concerns could be incorporated in the treatment of ARMS. A replication of the findings is required. Future longitudinal studies should examine whether Cognitive Concerns predict development of FEP in ARMS to improve early detection and prevention strategies.

Abstract Task-Centered Models include Cognitive-Behavior Therapy (CBT) and Task-Centered Therapy begins with light Cognitive Therapy focuses on thoughts, next Behavioral Therapy focus on act and reward application. Behavioural therapy also as a preface into task-centered therapy as conditioning. Comorbid symptoms of anxiety, aggression, and depression are target of changes. Using methods of action research, with Single Subject Design with pattern model of A-B at one baseline period (control) and two intervention period (treatments phase). The purpose of this study is to proof main hypothesis H1 = Task-Centered Models can reduce symptoms of anxiety, aggression and depression of respondent Y or H0 = Task-Centered Models can not reduce symptoms of anxiety, aggression and depression of respondent Y. Related with research setting, qualitative analysis of the research subjects should also be included. Hypothesis is tested by using the formula of 2 standard deviation (2 SD), visual analysis within and between conditions. Test result shows that the entire hypothesis is accepted with and fulfill criterias of visual analysis significant. Its concluded that intervention effectiveness define by motivation, participation and discipline,parent commitment is vital for therapy that demands action and consistency, maintaining cognitive of respondent are essential for reducing stressors of recurrence through recreational activity and positive emotion building.Key words: Psychiatric Social Worker, Psychiatric Disorder, Cognitive-Behavior Therapy, Task- Centered TherapyAbstrak Model Task-Centered meliputi Cognitive-Behaviour Therapy (CBT) dan Terapi Berpusat Tugas (Task-Centered), dimulai oleh Terapi Kognitif ringan yang fokus pada pikiran, kemudian Terapi Behavioral fokus pada kegiatan (tindakan) tujuan dan penentuan bentuk imbalan (rewards).

Abstract Background Contemporary models of psychosis implicate the importance of affective dysregulation and cognitive factors (e.g. biases and schemas) in the development and maintenance of psychotic symptoms, but studies testing proposed mechanisms remain limited. This study, uniquely using a prospective design, investigated whether the jumping to conclusions (JTC) reasoning bias contributes to psychosis progression and persistence. Methods Data were derived from the second Netherlands Mental Health Survey and Incidence Study (NEMESIS-2). The Composite International Diagnostic Interview and an add-on instrument were used to assess affective dysregulation (i.e. depression, anxiety and mania) and psychotic experiences (PEs), respectively. The beads task was used to assess JTC bias. Time series analyses were conducted using data from T1 and T2 (N = 8666), excluding individuals who reported high psychosis levels at T0. Results Although the prospective design resulted in low statistical power, the findings suggest that, compared to those without symptoms, individuals with lifetime affective dysregulation were more likely to progress from low/moderate psychosis levels (state of ‘aberrant salience’, one or two PEs) at T1 to high psychosis levels (‘frank psychosis’, three or more PEs or psychosis-related help-seeking behaviour) at T2 if the JTC bias was present [adj. relative risk ratio (RRR): 3.8, 95% confidence interval (CI) 0.8–18.6, p = 0.101]. Similarly, the JTC bias contributed to the persistence of high psychosis levels (adj. RRR: 12.7, 95% CI 0.7–239.6, p = 0.091). Conclusions We found some evidence that the JTC bias may contribute to psychosis progression and persistence in individuals with affective dysregulation. However, well-powered prospective studies are needed to replicate these findings.

AbstractPsychotic experiences (PE) are associated with poorer functioning, higher distress and the onset of serious mental illness. Environmental exposures (e.g. childhood abuse) are associated with the development of PE. However, which specific exposures convey risk for each type or dimension of PE has rarely been explored. The Oxford Wellbeing Life and Sleep (OWLS) survey includes 22 environmental risk factors for psychosis and was designed to examine how environmental risks are associated with specific dimensions of PE. Multivariate logistic regression models were fit using these risk factors to predict six dimensions of PE (perceptual abnormalities, persecutory ideation, bizarre ideas, cognitive disorganisation, delusional mood and negative symptoms). Models were built using only 70% of the data, and then fit to the remaining data to assess their generalisability and quality. 1789 (27.2% men; mean age = 27.6; SD = 10.9) survey responses were analysed. The risk factors predictive of the most PE were anxiety, social withdrawal during childhood and trauma. Cannabis and depression predicted three dimensions with both predicting bizarre ideas and persecutory ideation. Psychological abuse and sleep quality each predicted two dimensions (persecutory ideation and delusional mood). Risk factors predicting one PE dimension were age (predicting cognitive disorganisation), physical abuse (bizarre ideas), bullying and gender (persecutory ideation); and circadian phase (delusional mood). These results lend support for a continuum of psychosis, suggesting environmental risks for psychotic disorders also increase the risk of assorted dimensions of PE. Furthermore, it advocates the use of dimensional approaches when examining environmental exposures for PE given that environmental risks distribute differently across dimensions.
