Reliability of self-reports of alcohol use by community clients

Abstract

Eighty-five of 116 randomly selected clients receiving case management services at a comprehensive community mental health center responded anonymously to a survey questionnaire that included two measures of self-reported alcohol use: questions about frequency and quantity and a retrospective diary for reporting the number of drinks consumed daily in the preceding week. Forty-two patients reported using alcohol; consumption was higher among younger patients. A significant correlation was found between responses to the frequency-quantity questions and the information provided in the retrospective diary, indicating that self-reports of alcohol consumption are reasonably reliable for the clients studied. Future research is needed to establish the reliability and validity of self-reported alcohol and drug use in typical treatment settings.
