  The aim of this study is to investigate the validity of the Norwegian version of the Insight Scale (IS) in large and representative samples of patients with schizophrenia spectrum disorders, bipolar I disorder and bipolar II disorder. A total of 997 participants were included (schizophrenia spectrum disorders: 557; bipolar I disorder: 282; bipolar II disorder: 138). Confirmatory factor analysis was conducted to investigate the construct validity and bivariate correlational analysis was applied to investigate convergent validity. Confirmatory factor analyses indicated a reasonable model fit to the original three-factor subscale structure of the IS in all three diagnostic groups. The IS total score and its subscales correlated significantly with both the insight items in the Young Mania Rating Scale and the Positive and Negative Syndrome Scale in both schizophrenia spectrum disorders and bipolar I disorder. In the bipolar II disorder group, however, the IS subscales correlated poorly with both the observer-rated measures. Our study supports the construct validity of the IS in both schizophrenia spectrum disorder- and bipolar disorder populations. The study also demonstrates that patients’ self-reports of insight correspond to observer-based single item ratings of insight in bipolar I disorder and schizophrenia spectrum disorders.

  OBJECTIVES: Due to limited research on the association between recurrence of mood episodes and the longitudinal course of neurocognitive functioning in early phase bipolar I disorder (BD I), the impact of recurrence on neurocognition remains unclear. Further, a strong correlation between neurocognitive impairment and functional impairment has been demonstrated. The longitudinal relationship between neurocognitive impairment and functional outcome in relation to recurrence is, however, not established. METHODS: The current study investigated the longitudinal relationship between neurocognition, recurrence of mood episodes and functional outcome in a sample of first-treatment (FT) BD I patients (N = 42), with and without relapse, during a 1-year follow-up period. The longitudinal course of neurocognitive functioning in the patients was also compared to that of a group of healthy controls (N = 143). RESULTS: Compared to both patients with relapse and healthy controls, no-relapse patients showed neurocognitive improvements. The polarity of the relapse episodes was mostly depressive, and for the no-relapse patients, reduction of symptoms was associated with neurocognitive improvement. No-relapse patients showed better global and occupational functioning. CONCLUSIONS: The current study found different neurocognitive and functional trajectories in FT BD I patients with and without relapse, with differences at follow-up to some degree being mediated by current symptoms. The current findings highlight the importance of treatment focusing on neurocognition and symptom states with the aim of improving functional recovery.

  Background: Previous studies have shown that individuals with schizophrenia exhibit higher levels of unhelpful metacognitive beliefs than healthy controls, but no studies have explored metacognitive beliefs in early psychosis. Aims: We examined i) differences in levels of unhelpful metacognitive beliefs between psychosis spectrum disorders, and healthy controls, and ii) to what extent demographic and clinical characteristics predicted levels of metacognitive beliefs in the early treated phases of psychotic disorders. Method: Patients were included within two years of first treatment for a psychotic disorder (N=92). They were assessed on premorbid adjustment, psychotic symptoms, anxiety/depression, and self-reported metacognitive beliefs (MCQ-30). Ninety-seven controls also completed MCQ-30. Predictors of metacognitive beliefs were explored with multiple linear regression analyses. Results: Patients scored significantly higher than controls on all metacognitive subscales except positive beliefs about worry. The regression model explained 14—38% of the variance on each metacognitive subscale. Current affective symptoms explained a significant amount of variance on all subscales, except positive beliefs about worry. Childhood (premorbid) social adjustment predicted a significant amount of the variance on all subscales, except cognitive confidence. Duration of untreated psychosis contributed significantly to more unhelpful beliefs about cognitive confidence. Negative symptoms predicted lower scores on cognitive self-consciousness. Conclusion: Affective symptoms and childhood social adjustment could be important predictors of unhelpful metacognitive beliefs in the early treated phases of psychosis, indicating potential psychopathological relationships that warrant further investigation for clinical relevance.
