Background: This study addresses the question of whether psychosocial functioning measured by the Personal and Social Performance (PSP) Scale is related to various psychopathological measures in a cohort of patients with schizophrenia.
Methods: The 'Neuroleptic Strategy Study' (NeSSy) performed at 14 German hospitals between 2010 and 2013 compared two treatment strategies instead of individual drugs. Secondary end-points were the two PSP scales as well as measures of quality of life (SF-36) and the Positive and Negative Syndrome Scale (PANSS).
Results: 149 patients were randomised. There was no difference between the two treatment strategies (first-generation versus second-generation antipsychotics) with regard to the PSP. There were differences in doctors' assessments regarding psychosocial functioning compared with patients' own assessments. Furthermore, there were relationships between the PSP and quality of life, level of skills (ICF), and severity of disease (PANSS), level of sexual activities and poor well-being under antipsychotic medication but not with cognitive changes.
Conclusions: The findings on psychosocial functioning of patients with schizophrenia related to severity and skill level could be confirmed. Further findings were the correlation between psychosocial functioning and quality of life, well-being under treatment, and sexuality what emphasizes the substantial importance of a reduced psychosocial functioning.
