Abstract:
There has been concern about the impact of cannabis use on the onset, course and relapse of psychosis. Evidence from retrospective and a small number of prospective studies has suggested that cannabis use may precipitate a latent psychosis, exacerbate psychotic symptoms and increase the likelihood of psychotic relapse. The purpose of the current study was to examine the influence of cannabis use on psychotic symptom exacerbation and relapse within the stress vulnerability-coping model of psychosis. Two studies were conducted. The influence of cannabis use on the onset and course of psychos

Abstract:
The onset of a psychotic disorder causes much distress, and has negative health consequences, for the affected individuals and their families. As the highest risk time for initial onset of psychoses is in late adolescence and early adulthood, most people developing psychoses live with their parents. Often the sufferer has little insight into their deteriorating mental health, and is reliant on parents to identify that there is a problem and to seek treatment for the sufferer. However, during the onset of psychoses behaviour often gradually deteriorates, and the family members are often confuse

Psychosis is a term used to describe a range of experiences often associated with significant distress. Interpretative Phenomenological Analysis (IPA) is a qualitative method which focuses on the first person perspective to understand lived experience and how an individual makes sense of that experience.

The first paper is a systematic review assessing the quality of IPA studies which explore the subjective experience of psychosis from a range of different perspectives, including service user, family and professional.

Given the heterogeneity of symptoms allowed in the diagnosis of psychotic disorders, as well as other challenges of categorical diagnosis (e.g., First et al., 2002; Krueger, 1999), the increased specificity brought by dimensional ratings of underlying features is often important. Models using the factorial structure of psychotic symptoms perform as good as or better than traditional categorical models (Allardyce, Suppes, & Van Os, 2007).

Abstract:
People with severe mental illness are at increased risk of heart disease and diabetes. First episode psychosis (FEP) patients tend to engage in health-risk behaviours, typically consuming an unhealthy diet and engaging in low levels of physical activity. Protection Motivation Theory proposes that risk perceptions are the most proximal determinants of such behaviour. Understanding the risk perceptions of FEP patients may therefore have the potential to inform health behaviour change interventions. This thesis reports findings from a prospective cohort study, in which FEP patients completed a ba

Abstract:
The study aimed to examine the relationship between wellbeing, burden, distress and third-wave factors, including self-compassion and psychological flexibility, in caregivers of people with psychosis. The study secondly aimed to trial a new brief group intervention, combining Acceptance and Commitment Therapy (ACT) and Compassion-focused Therapy (CFT) for this population. Twenty-nine participants were assessed at baseline on primary measures of wellbeing, distress, psychological flexibility and self-compassion. Secondary factors including burden and mindfulness were also collected. Correlation

Abstract:
In this thesis we have attempted to address the complex issue of the relationship between trauma, dissociation, and psychosis. It is hypothesised that dissociation, occurred as a result of trauma, plays a key role in the formation and maintenance of psychotic symptoms, chiefly hallucinations and delusions. We have used methods from experimental psychopathology to investigate the potential role played by dissociative processes in the disruption of the cognitive processes of attention and memory for trauma-related, positive and neutral information in two groups of participants: 30 individuals wi

Abstract:
There is an increasing awareness of the limitations of Cognitive Behavioural Therapy for psychosis (CBTp) and researchers are attempting to advance its efficacy. The first part of this thesis was a systematic review of the new CBT approaches for positive symptoms. The evidence for their efficacy was summarised and then examined from a methodological perspective. A search of the literature since 2003 produced sixteen studies, falling into two main strands: an interventionist causal model approach, with studies indicating the potential for greater effect sizes for both persecutory delusions and

Abstract:
Background / Objectives: Mental diseases are perceived as one of the highest stigmatised conditions in our society. Public knowledge of mental illness does not come from professional journals or medical authorities, but largely from mass media as it is a major and most convenient source of information. Media tends to portray mental illness with negative attitude, focusing on bizarre and unexplainable behaviours of patients with mental illness, and exaggerating the linkage between mental illness and aggressive behaviours. However, few studies have been conducted in Hong Kong focusing on media
