Relationship between psychosocial adjustment and executive function in patients with bipolar disorder and schizophrenia in remission: the mediating and moderating effects of insight.
OBJECTIVE
The aims of this study were to examine the relationships between executive function and psychosocial adjustment, and the mediating and moderating effects of insight on the association between executive function and psychosocial adjustment in patients with bipolar disorder and schizophrenia in clinical remission.


METHODS
The level of psychosocial adjustment was assessed in 96 subjects with bipolar disorder and 96 subjects with schizophrenia who were in remitted state. The association between executive function and psychosocial adjustment and the mediating and moderating effects of insight were examined by multiple regression analysis models and the Goodman test.


RESULTS
The results indicated that executive function had direct effect on psychosocial adjustment in both subjects with bipolar disorder and schizophrenia. However, the mediating effect of insight on the association between executive function and psychosocial adjustment was only found in subjects with schizophrenia, but not in subjects with bipolar disorder. No moderating effect of insight on the association between executive function and psychosocial adjustment was found in subjects with schizophrenia or bipolar disorder.


CONCLUSIONS
The results of this study indicated that executive function has an important role in psychosocial adjustment in both patients with bipolar disorder and schizophrenia. Meanwhile, insight has a different role in the association between executive function and psychosocial adjustment between patients with bipolar disorder and schizophrenia.
