title: Association of adverse drug effects with subjective well-being in patients with schizophrenia receiving stable doses of risperidone.
abstract: OBJECTIVE
  The purpose of the present study was to examine the association of adverse drug effects with subjective well-being in patients with schizophrenia receiving stable doses of risperidone.
  
  
  METHODS
  Thirty outpatients with schizophrenia receiving stable doses of risperidone were comprehensively evaluated for psychopathology, subjective well-being, and adverse drug effects. Subjective well-being was assessed using the Subjective Well-being Under Neuroleptics Scale (SWN). Adverse drug effects were evaluated using the Liverpool University Neuroleptic Side Effect Rating Scale (LUNSERS) and the Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS).
  
  
  RESULTS
  In correlation analysis controlling for relevant variables, the SWN score had significant negative correlations with the following subscale scores of the LUNSERS: extrapyramidal side effect (EPS) (r = -0.54, P < 0.01), akathisia (r = -0.46, P < 0.05), and autonomic adverse effect (r = -0.44, P < 0.05). The SWN score also had a significant negative correlation with the global severity of EPS as measured by the DIEPSS (r = -0.44, P < 0.05).
  
  
  CONCLUSIONS
  The results of our study suggest that adverse effects, particularly EPS and akathisia, are significantly associated with subjective well-being, implying the necessity to develop rational strategies to control these variables effectively. The results also suggest that EPS and akathisia continue to be major adverse effects associated with a low level of subjective well-being in patients receiving risperidone. Further studies are required to investigate the multidimensional factors associated with subjective well-being in patients receiving atypical antipsychotics and to determine their relative contributions.
