The Brief Core Schema Scales (BCSS): psychometric properties and associations with paranoia and grandiosity in non-clinical and psychosis samples.

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.

Negative Cognition, Depressed Mood, and Paranoia: A Longitudinal Pathway Analysis Using Structural Equation Modeling

The role of negative cognition and effect in maintaining psychotic symptoms is increasingly recognized but has yet to be substantiated though longitudinal analysis. Based on an a priori theoretical model, we hypothesized that negative cognition and depressed mood play a direct causal role in maintaining paranoia in people with psychosis and that the effect of mood is mediated by negative cognition. We used data from the 301 patients in the Prevention of Relapse in Psychosis Trial of cognitive behavior therapy. They were recruited from consecutive Community Mental Health Team clients presenting with a recent relapse of psychosis. The teams were located in inner and outer London and the rural county of Norfolk, England. The study followed a longitudinal cohort design, with initial measures repeated at 3 and 12 months. Structural equation modeling was used to investigate the direction of effect between negative cognition, depressed mood, and paranoia. Overall fit was ambiguous in some analyses and confounding by unidentified variables cannot be ruled out. Nevertheless, the most plausible models were those incorporating pathways from negative cognition and depressed mood to paranoid symptoms: There was no evidence whatsoever for pathways in the reverse direction. The link between depressed mood and paranoia appeared to be mediated by negative cognition. Our hypotheses were thus corroborated. This study provides evidence for the role of negative cognition in the maintenance of paranoia, a role of central relevance, both to the design of psychological interventions and to the conceptualizations of psychosis.

Effectiveness of cognitive behavioural therapy with people who have autistic spectrum disorders: A systematic review and meta-analysis.

The aims of this study were to undertake a meta-analytic and systematic appraisal of the literature investigating the effectiveness of cognitive behavioural therapy (CBT) when used with individuals who have autistic spectrum disorders (ASDs) for either a) affective disorders, or b) the symptoms of ASDs. Following a systematic search, 48 studies were included. CBT, used for affective disorders, was associated with a non-significant small to medium effect size, g=0.24, for self-report measures, a significant medium effect size, g=0.66, for informant-report measures, and a significant medium effect size, g=0.73, for clinician-report measures. CBT, used as a treatment for symptoms of ASDs, was associated with a small to medium non-significant effect size, g=0.25, for self-report measures, a significant small to medium effect size, g=0.48, for informant-report measures, a significant medium effect size, g=0.65, for clinician-report measures, and a significant small to medium effect size, g=0.35, for task-based measures. Sensitivity analyses reduced effect size magnitude, with the exception of that based on informant-report measures for the symptoms of ASDs, which increased, g=0.52. Definitive trials are needed to demonstrate that CBT is an empirically validated treatment for use with people who have ASDs.

CBT and Recovery From Psychosis in the ISREP Trial: Mediating Effects of Hope and Positive Beliefs on Activity

OBJECTIVE Hope and positive self-concept have been highlighted as important components of recovery from psychosis. This study investigated the impact of a recovery-focused intervention on these dimensions, as well as their role as mediators of functional outcome. METHODS Seventy-seven participants in recovery from psychosis were recruited into a randomized controlled trial of social recovery-focused cognitive-behavioral therapy (SRCBT). The primary outcome was hours spent weekly in structured activity. Hopelessness and beliefs about self and others were also assessed. RESULTS SRCBT had a significant effect on improving positive beliefs about self and others. A trend was noted suggesting a main effect of SRCBT on reducing hopelessness among individuals with nonaffective psychosis. Increases in positive beliefs about self were found to mediate improvements in activity in the SRCBT group. CONCLUSIONS Fostering hope and positive self-concept should be central components of recovery-oriented services and interventions. Modifying these dimensions may have a positive impact on functional outcome.

Investigating trajectories of social recovery in individuals with first-episode psychosis: a latent class growth analysis

Background Social disability is a hallmark of severe mental illness yet individual differences and factors predicting outcome are largely unknown. Aim To explore trajectories and predictors of social recovery following a first episode of psychosis (FEP). Method A sample of 764 individuals with FEP were assessed on entry into early intervention in psychosis (EIP) services and followed up over 12 months. Social recovery profiles were examined using latent class growth analysis. Results Three types of social recovery profile were identified: Low Stable (66%), Moderate-Increasing (27%), and High-Decreasing (7%). Poor social recovery was predicted by male gender, ethnic minority status, younger age at onset of psychosis, increased negative symptoms, and poor premorbid adjustment. Conclusions Social disability is prevalent in FEP, although distinct recovery profiles are evident. Where social disability is present on entry into EIP services it can remain stable, highlighting a need for targeted intervention.

Cognitive bias modification in the treatment of social anxiety in early psychosis: a single case series.

BACKGROUND Social anxiety is a common problem among people who are recovering from psychosis. At present there is no evidence based psychological treatment targeting social anxiety in this population. Cognitive Bias Modification for Interpretation (CBM-I) has been shown to be effective in reducing social anxiety in people who do not have a history of psychosis. AIMS To assess the feasibility and acceptability of the CBM-I methodology for use in a clinical setting with people who are experiencing social anxiety following an episode of psychosis. METHOD Eight participants with social anxiety were recruited from an early intervention service. A single session of computerized CBM-I was conducted, with mood and cognitive interpretation bias being assessed before and after the session. RESULTS All participants reported an improvement in mood immediately following the CBM-I session (n=8). For those participants who had a negative interpretation bias, none became more negative following the CBM-I session, with three out of six participants showing a beneficial change. CONCLUSION These results suggest that CBM-I is acceptable for use with people who are experiencing social anxiety following a psychotic episode. Further research looking at how CBM-I could be made more interactive and producing more applicable scenarios for use in a clinical setting is recommended.

Participant views on involvement in a trial of social recovery cognitive–behavioural therapy

BACKGROUND The PRODIGY trial (Prevention of long term social disability amongst young people with emerging psychological difficulties, ISRCTN47998710) is a pilot trial of social recovery cognitive-behavioural therapy (SRCBT). AIMS The PRODIGY qualitative substudy aimed to (a) explore individual experiences of participating in the pilot randomised, controlled trial (recruitment, randomisation, assessment) and initial views of therapy, and (b) to explore perceived benefits of taking part in research v. ethical concerns and potential risks. METHOD Qualitative investigation using semi-structured interviews with thematic analysis. RESULTS Analysis revealed participant experiences around the key themes of acceptability, disclosure, practicalities, altruism and engagement. CONCLUSIONS Participants in both trial arms perceived themselves as gaining benefits from being involved in the study, above and beyond the intervention. This has implications for the design of future research and services for this client group, highlighting the importance of being flexible and an individualised approach as key engagement tools.

Pathways to care of young people accessing a pilot specialist youth mental health service in Norfolk, United Kingdom.

Pathways to care (PtC) are a means of examining and understanding routes into mental health care. It is important to examine PtC in order to identify ways in which individuals access services, as well as highlighting barriers or delays to appropriate treatment. This study aimed to examine PtC experienced by young people accessing a pilot specialist youth mental health service (SYMHS) for those with non‐psychotic, severe and complex mental health conditions in Norfolk, UK.

A review of abnormalities in the perception of visual illusions in schizophrenia.

Specific abnormalities of vision in schizophrenia have been observed to affect high-level and some low-level integration mechanisms, suggesting that people with schizophrenia may experience anomalies across different stages in the visual system affecting either early or late processing or both. Here, we review the research into visual illusion perception in schizophrenia and the issues which previous research has faced. One general finding that emerged from the literature is that those with schizophrenia are mostly immune to the effects of high-level illusory displays, but this effect is not consistent across all low-level illusions. The present review suggests that this resistance is due to the weakening of top–down perceptual mechanisms and may be relevant to the understanding of symptoms of visual distortion rather than hallucinations as previously thought.
