  • Title: Psychotic symptoms, cognition and affect as predictors of psychosocial problems and functional change in first-episode psychosis.
    Author: Stouten LH, Veling W, Laan W, van der Helm M, van der Gaag M.
    Journal: Schizophr Res; 2014 Sep; 158(1-3):113-9. PubMed ID: 25008791.
    Abstract:
    OBJECTIVE: To enable further understanding of how cognitive deficits and psychopathology impact psychosocial functioning in first-episode psychosis patients, we investigated how psychopathology and cognitive deficits are associated with psychosocial problems at baseline, and how these predict psychosocial functioning at 12 months follow-up. Also, we tested whether the effect of baseline psychopathology on psychosocial functioning decreases between baseline and 12 months and the effect of baseline cognition increases. METHODS: Eight neurocognitive and four social cognitive subdomains and psychopathology (positive and negative symptoms, depression and anxiety) were assessed at baseline in 153 non-affective first-episode psychosis (FEP) patients. Psychosocial functioning (work/study, relationships, self-care, disturbing behavior and general psychosocial functioning) was assessed at baseline and 12 months. Spearman correlations were examined and backward regression models were computed to test our hypotheses. RESULTS: At baseline, psychosocial functioning was associated strongest with positive and negative symptoms of all assessed clinical domains, followed by neurocognition and social cognition. In contrast, psychosocial functioning at 12 months was not predicted by psychotic symptoms, but rather by neurocognition, social cognition and depression. Change in social functioning in the first 12 months after baseline was predicted by positive and negative symptoms, but to a similar degree by neurocognition and social cognition. CONCLUSIONS: Whereas psychotic symptoms show marked impact on psychosocial functioning at illness onset, cognitive deficits appear to be more accurate longitudinal predictors of psychosocial problems and functional recovery in the early course of psychosis.
