![]() Research of psychotic disorders has been hampered by the heterogeneity of the phenomena to be explained and the lack of an agreed framework for integrating the wide range of abnormalities identified by biological and psychological investigators. Treatment for paranoid patients should address both types of processes. Pessimistic thinking correlated highly with paranoia even when controlling for cognitive performance ( r = 0.65, P < .001), and cognitive performance correlated with paranoia when controlling for pessimism ( r = −0.34, P < .001).Ĭonclusions Both cognitive and emotion-related processes are involved in paranoid delusions. Results The best fitting (χ 2 96 = 131.69, P = .01 comparative fit index = 0.95 Tucker-Lewis Index = 0.96 root-mean-square error of approximation = 0.04) and most parsimonious model of the data indicated that paranoid delusions are associated with a combination of pessimistic thinking style (low self-esteem, pessimistic explanatory style, and negative emotion) and impaired cognitive performance (executive functioning, tendency to jump to conclusions, and ability to reason about the mental states of others). ![]() Main Outcome Measures Assessments of theory of mind, jumping to conclusions bias, and general intellectual functioning, with measures of threat anticipation, emotion, self-esteem, and explanatory style. Sixty-four healthy control participants matched for appropriate demographic variables were included. Participants One hundred seventy-three patients with schizophrenia spectrum disorders, major depression, or late-onset schizophrenia-like psychosis, subdivided according to whether they were currently experiencing paranoid delusions. Setting Publicly funded psychiatric services in London and the North West of England. Objective To determine the structure of the relationships among psychological mechanisms contributing to paranoia in a transdiagnostic sample.ĭesign Cross-sectional design, with relationships between predictor variables and paranoia examined by structural equation models with latent variables. A variety of psychological mechanisms have been implicated in their cause, including a tendency to jump to conclusions, an impairment in the ability to understand the mental states of other people (theory of mind), an abnormal anticipation of threat, and an abnormal explanatory style coupled with low self-esteem.
