ATTRIBUTIONAL REASONING BIASES, PARANOIA AND DEPRESSION IN FIRST-EPISODE SCHIZOPHRENIA

摘要: Background: Evidence that paranoid people with schizophrenia show a 'self-serving' bias, whereby they externalize the blame for negative events, has prompted development of 'attributional interventions' to augment cognitive behavioral therapies. However, longitudinal and first-episode research validate these interventions is lacking. This study aimed address this gap in literature by examining attributional biases, paranoia depression sample patients. Methods: Twenty-four young schizophrenia-spectrum disorders (23 males one female mean age 20.9 years, SD=1.8) were recruited from two early psychosis intervention services Sydney, Australia. Inclusion criteria included less than years since onset psychosis, minimum 18 English-speaking, no current major co-morbidity. Nineteen healthy controls (19 females 20.8 SD=1.7) also took part. Patient diagnosis was confirmed using Diagnostic Interview Psychosis (Castle et al., 2006) symptom severity rated SAPS, SANS BPRS. All participants assessed levels (Paranoia Scale; Fenigstein & Vanable, 1992), suspiciousness (BPRS), (Hamilton Depression Scale: HAM-D; Hamilton, 1967) biases (Internal, Personal Situational Attributions Questionnaire: IPSAQ; Kinderman Bentall, 1997). Results: Across patients controls, associated standard measure self-serving bias (SSB: proportion positive events attributed self minus self); however, SSBwere nomore extreme controls. First-episode did, greater 'self-promoting' credit themselves causing (but not negative) events. Whereas showed evidence commonly observed association between one-self patientswere associated, instead, both Discussion: Findings are indicative universal at stages schizophrenic illness suggest, form compensatory self-promoting which may be secondary psychosis. The novel findings regard suggest people, who develop after experience need re-establish sense personal control over life whether or negative.
