Objectives : Paranoia is a complex phenomenon, affected by a number of factors such as depression, trait anxiety, and attributional bias in schizophrenia. The aim of this study was to explore whether paranoia within continuum of clinical and subclinical states is associated with emotional dysregulation, attributional bias and neurocognitive impairment in whole individuals of normal controls, ultra-high risk (UHR) for psychosis and schizophrenia.
Methods : 101 normal controls, 50 participants at UHR for psychosis, and 49 schizophrenia patients were recruited. All subjects were asked to complete self-reported paranoia scale and emotional dysregulation scales including Rosenberg's self-esteem, Spielberg's state-trait anxiety inventory and Beck depression inventory. The attributional style was assessed by Ambiguous Intentions Hostility Questionnaire (AIHQ). Participants were also requested to complete the comprehensive neurocognitive battery.
Results : Multiple linear regression analysis showed that paranoia were found to be associated with emotional dysregulation (state anxiety, trait anxiety and depression), composite blaming bias in ambiguous situation, impairment of attention and working memory in whole participants [F (9, 190)=34.85, p<0.001, adjusted R2=0.61].
Conclusion: The main findings suggest that paranoia is a complex affective and cognitive structure that may be associated with emotional dysregulation, blaming bias and attention and working memory impairment in clinical and non-clinical paranoia.
