Neuropsychological functioning as a moderator of the relationship between psychosocial functioning and the subjective experience of self and life in schizophrenia.

Journal Article

Psychosocial interventions and models of quality of life in schizophrenia are based on the notion that increases in psychosocial functioning will be related to improvements in subjective experience outcomes such as self-esteem and satisfaction with life. However, studies have repeatedly failed to demonstrate a direct relationship between psychosocial functioning and subjective experience in schizophrenia. This study of 40 individuals diagnosed with schizophrenia examined whether neurocognitive measures of executive functioning moderated the relationship between psychosocial functioning and subjective experience. Subjective experience was represented by measures of satisfaction with life and self-esteem. The Global Assessment Scale measured psychosocial functioning, and the Wisconsin Card Sorting Test measured executive functioning. Multiple regression and correlation analyses indicated that executive functioning was a strong moderator. Specifically, individuals with schizophrenia with impaired executive functioning displayed a positive and statistically significant association between psychosocial functioning and both measures of subjective experience (r = 0.55 and 0.61). However, among schizophrenia patients with intact executive performance, psychosocial functioning was negatively associated with self-esteem and satisfaction with life (r = -0.24 and -0.46). And the findings were internally replicated using two other neuropsychological measures relevant to executive functioning. These findings indicate that executive functioning plays a major role in moderating the relationship between subjective experience and psychosocial functioning in schizophrenia. Implications for biosocial models, psychosocial interventions, and models of quality of life in schizophrenia are discussed.
