BACKGROUND: On the basis of the concept of psychotic and psychotic-like experiences, delusions and auditory hallucinations presented in Part 1 of this article, the structure of the links between psychotic experiences and social anxiety and its components and psychological parameters is analyzed.

Abstract:
BackgroundThe incidence of schizophrenia and the prevalence of psychotic symptoms in the general adult population are elevated in migrant and ethnic minority groups relative to host populations. These increases are particularly prominent among African-Caribbean migrants to the UK. This study examined the associations of ethnicity and migrant status with a triad of putative antecedents of schizophrenia in a UK community sample of children aged 9–12 years. The antecedent triad comprised: (i) psychotic-like experiences; (ii) a speech and/or motor developmental delay or abnormality; and (iii) a so

 This research was exploratory and its main objective was to analyze whether anomalous experiences related to parapsychology had similar statistical behavior to psychotic-like experiences (e.g., hallucinations).

PurposeThe purpose of this paper is to explore the relationship between attachment style, sub-clinical symptoms of psychosis and aggression in a general population sample.Design/methodology/approachUsing both convenience and snowball sampling, participants in the community (n=213) completed an online questionnaire including previously validated measures of adult attachment, aggression and psychotic experiences.FindingsResults suggested that there were statistically significant correlations between all study variables. Multiple linear regression demonstrated that total psychotic-like experience

Abstract:
BackgroundPsychotic-like experiences (PLEs) in the general population are common, particularly in childhood, and may constitute part of a spectrum of normative development. Nevertheless, these experiences confer increased risk for later psychotic disorder, and are associated with poorer health and quality of life.MethodThis study used factor analytic methods to determine the latent structure underlying PLEs, problem behaviours and personal competencies in the general child population, and used item response theory (IRT) to assess the psychometric properties of nine PLE items to determine which

Abstract:
Aberrant salience (AS) is an anomalous world experience which plays a major role in psychotic proneness. In the general population, a deployment of this construct – encompassing personality traits, psychotic-like symptoms, and cannabis use – could prove useful to outline the relative importance of these factors. For this purpose, 106 postgraduate university students filled the AS Inventory (ASI), the Community Assessment of Psychic Experiences (CAPE), the Temperament and Character Inventory (TCI), and the Symptom Checklist 90-Revised (SCL-90-R).

Abstract:
Abstract Background Substance use (tobacco, cannabis and alcohol consumption) is associated with the risk of developing a psychotic disorder as well as the risk of presenting psychotic experiences. We aimed to study the associations between substance use and psychotic-like experiences in a sample of healthy adolescents aged between 14 and 15 years. We also aimed to study potential relationships with bullying and cognitive biases. Methods A sample of 207 adolescents born in 2004 and studying in high schools from Sabadell. After excluding 33 participants who were receiving mental health care, a
