A cognitive model of the positive symptoms of psychosis
TLDR
The cognitive processes that are thought to lead to the formation and maintenance of the positive symptoms of psychosis are set out and a fuller integration with the findings of biological research will be required.
Psychological investigation of the structure of paranoia in a non-clinical population
TLDR
Assessing a wide range of paranoid thoughts multidimensionally and examining their distribution, to identify the associated coping strategies and to examine social–cognitive processes and paranoia found suspiciousness is common and there may be a hierarchical arrangement of such thoughts that builds on common emotional concerns.
A cognitive model of persecutory delusions.
TLDR
A multifactorial model of the formation and maintenance of persecutory delusions is presented, which includes the (non-defended) direct roles given to emotion in delusion formation, the detailed consideration of both the content and form of delusions, and the hypotheses concerning the associated emotional distress.
Responding mindfully to unpleasant thoughts and images: reliability and validity of the Southampton mindfulness questionnaire (SMQ).
TLDR
The SMQ has a single factor structure, was internally reliable, significantly correlated with the MAAS, showed expected associations with affect, and distinguished among meditators, non-meditators and people with psychosis.
Measuring ideas of persecution and social reference: the Green et al. Paranoid Thought Scales (GPTS)
TLDR
The development of a reliable and valid tool to assess ideas of persecution and social reference in a simple self-report format is presented, guided by a current definition of persecutory ideation and incorporating assessment of conviction, preoccupation and distress.
The Brief Core Schema Scales (BCSS): psychometric properties and associations with paranoia and grandiosity in non-clinical and psychosis samples
TLDR
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.
Psychological treatments in schizophrenia: I. Meta-analysis of family intervention and cognitive behaviour therapy
TLDR
Family therapy, in particular single family therapy, had clear preventative effects on the outcomes of psychotic relapse and readmission, and CBT produced higher rates of ‘important improvement’ in mental state and demonstrated positive effects on continuous measures of mental state at follow-up.
Reasoning, emotions, and delusional conviction in psychosis.
TLDR
There was evidence that belief inflexibility mediated the relationship between jumping to conclusions and delusional conviction, and anxiety, but not depression, made an independent contribution to delusional conviction.
Persecutory delusions: developing the understanding of belief maintenance and emotional distress
TLDR
Support was found for the hypothesis that emotional distress is linked to the content of delusional beliefs; it is speculated that prior emotional distress influences thecontent of delusions, and that delusion content in turn influences levels of emotional distress.
