Compliance with neuroleptic medication in outpatients with schizophrenia; relationship to subjective response to neuroleptics; attitudes to medication and insight.

The relationship between compliance, subjective response to neuroleptics, attitudes to medication, and insight was assessed in a selected group of individuals with schizophrenia who were attending a catchment area outpatient psychiatric service. Regular compliers with medication reported a significantly better subjective response to neuroleptics and were more frequently prescribed depot medication compared with individuals who were irregularly compliant. There was no difference between regular and irregular compliers in terms of attitudes to medication or level of insight. There was a significant correlation between the measures of insight obtained using a self-report questionnaire (the Insight Scale [IS]) and a semistructured interview (the Scale for Assessment of Insight [SAI]).
