Abstract:
The overall theme of the thesis is the investigation of psychological mechanisms of the relationship between early adversity and psychosis. Firstly, a systematic literature review regarding the psychological mediators of the relationship between childhood trauma and psychosis is presented. Paper 1 provides a comprehensive review of 30 studies investigating putative psychological mediators of the relationship between childhood trauma and psychosis symptomatology. The review critically synthesises and evaluates the research that has been carried out and published to date. Different traumatic sequalae received some support including post-traumatic symptoms, affective symptoms, emotion regulation, dissociation and insecure attachment; some factors were more tentative, including negative schema and self-esteem. The results are considered in relation to methodological limitations, clinical implications and recommendations for future research. Secondly, research was carried out to explore dissociation as a potential mediating variable within the fearful attachment and voice-hearing relationship. Paper 2 presents an investigation involving 50 participants with a diagnosis of psychosis. The participants completed a range of self-report measures. Mediation analysis indicated that a fear-based attachment style may predispose an individual to voice-hearing if dissociation is a sequalae of this experience, and highlights the importance of affect regulation in this pathway. The findings are considered in relation to limitations of the study and possible clinical implications and recommendations for future research. Thirdly, a critical evaluation and reflection of the two papers mentioned above was carried out. Strengths and weaknesses regarding the chosen methodology, directions for theory, clinical practice and future research were considered. Finally, the overall research process was reflected upon.
