Identifying subgroups based on self-assessment of ability in patients with schizophrenia and its relationship with vocational outcomes
BACKGROUND/OBJECTIVES: People with schizophrenia have defective self-assessment of ability (i.e., loss of introspective accuracy [IA]). Although previous studies grouped people according to the degree of IA, the clinical features of these subgroups have not been clarified. Additionally, the determin...

description | BACKGROUND/OBJECTIVES: People with schizophrenia have defective self-assessment of ability (i.e., loss of introspective accuracy [IA]). Although previous studies grouped people according to the degree of IA, the clinical features of these subgroups have not been clarified. Additionally, the determinants of outcomes depending on self-assessment remain unknown. We aimed to identify the clinical features that can help distinguish these subgroups and whether the determinants of vocational outcomes differed between the groups. METHODS: The self-assessment ability of 100 people with schizophrenia was examined and categorized as accurate, over-, or under-estimators. Multiple discriminant analysis was also performed. After demonstrating statistical validity, the relative effects of positive and negative symptoms, cognitive function, and level of IA on vocational outcomes were also examined for each subgroup. RESULTS: The symptoms that particularly explained the differences between these subgroups were positive and negative (expressing factors) symptoms: p < .001. Using the determinants of vocational outcomes in each subgroup, the over-estimator subgroup was characterized by positive symptoms: p = .025, the under-estimator group, by the underestimation of their own ability: p = .042, and the accurate estimator group, by cognitive function: p = .006. CONCLUSION: Reduced IA can be a core mediator of various symptoms. Thus, tailoring the target and strategy of interventions for vocational outcomes according to the accuracy and quality of IA is important in clinical settings. |
