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, with post-hoc planned 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.

BackgroundSocial anxiety disorder (SAD) is surprisingly prevalent among people with psychosis and exerts significant impact on social disability. The processes that underlie its development remain unclear. The aim of this study was to investigate the relationship between shame cognitions arising from a stigmatizing psychosis illness and perceived loss of social status in co-morbid SAD in psychosis.MethodThis was a cross-sectional study. A sample of individuals with SAD (with or without psychosis) was compared with a sample with psychosis only and healthy controls on shame proneness, shame cognitions linked to psychosis and perceived social status.ResultsShame proneness (p < 0.01) and loss of social status (p < 0.01) were significantly elevated in those with SAD (with or without psychosis) compared to those with psychosis only and healthy controls. Individuals with psychosis and social anxiety expressed significantly greater levels of shame (p < 0.05), rejection (p < 0.01) and appraisals of entrapment (p < 0.01) linked to their diagnosis and associated stigma, compared to those without social anxiety.ConclusionsThese findings suggest that shame cognitions arising from a stigmatizing illness play a significant role in social anxiety in psychosis. Psychological interventions could be enhanced by taking into consideration these idiosyncratic shame appraisals when addressing symptoms of social anxiety and associated distress in psychosis. Further investigation into the content of shame cognitions and their role in motivating concealment of the stigmatized identity of being ‘ill’ is needed. [ABSTRACT FROM PUBLISHER]

Cannabis use and age at onset of symptoms in subjects at clinical high risk for psychosis. Objective: Numerous studies have found a robust association between cannabis use and the onset of psychosis. Nevertheless, the relationship between cannabis use and the onset of early (or, in retrospect, prodromal) symptoms of psychosis remains unclear. The study focused on investigating the relationship between cannabis use and early and high-risk symptoms in subjects at clinical high risk for psychosis. Method: Prospective multicenter, naturalistic field study with an 18-month follow-up period in 245 help-seeking individuals clinically at high risk. The Composite International Diagnostic Interview was used to assess their cannabis use. Age at onset of high risk or certain early symptoms was assessed retrospectively with the Interview for the Retrospective Assessment of the Onset of Schizophrenia. Results: Younger age at onset of cannabis use or a cannabis use disorder was significantly related to younger age at onset of six symptoms (0.33 < r
s < 0.83, 0.004 < P < 0.001). Onset of cannabis use preceded symptoms in most participants. Conclusion: Our results provide support that cannabis use plays an important role in the development of psychosis in vulnerable individuals. Cannabis use in early adolescence should be discouraged.

Upthegrove R, Birchwood M, Ross K, Brunett K, McCollum R, Jones L. The evolution of depression and suicidality in first episode psychosis. Objective: To have a clearer understanding of the ebb and flow of depression and suicidal thinking in the early phase of psychosis, whether these events are predictable and how they relate to the early course of psychotic symptoms. Method: Ninety-two patients with first episode psychosis (FEP) completed measures of depression, including prodromal depression, self-harm and duration of untreated psychosis. Follow-up took place over 12 months. Results: Depression occurred in 80% of patients at one or more phases of FEP; a combination of depression and suicidal thinking was present in 63%. Depression in the prodromal phase was the most significant predictor of future depression and acts of self-harm. Conclusion: Depression early in the emergence of a psychosis is fundamental to the development of future depression and suicidal thinking. Efforts to predict and reduce depression and deliberate self-harm in psychosis may need to target this early phase to reduce later risk. [ABSTRACT FROM AUTHOR]

Therapeutic intervention in psychotic disorders has been evolving steadily in recent years with notable changes in the content of treatment (e.g., atypical neuroleptics and the cognitive/psychosocial interventions) and the locus of care. While the therapeutic focus continues to emphasize acute and treatment symptoms, and longer-term interventions, for example assertive community treatment, the primary and secondary prevention of psychosis has received little attention since Cameron's (1938) pioneering work. It is now believed that the variables influencing the early phase of psychosis are sufficiently well developed to begin exploring their therapeutic implications. More speculatively, the early phase of psychosis is believed to be formative in biological, psychological, and social terms, thus affording major opportunities for secondary prevention. Three key elements of an early intervention strategy are proposed: early detection of “at-risk” mental states; early treatment of first psychotic epis...
