Development and Evaluation of the Lifestyle History Questionnaire (LHQ) for People Entering Treatment for Substance Addictions.

Objective: We developed and investigated the psychometric properties of the Lifestyle History Questionnaire (LHQ), a self-report instrument designed to measure the extent of occupational dysfunction attributable to substance abuse.

Method: The instrument was developed using concepts in the ecological models of occupational therapy and in the work of William L. White, who defined addiction culture in terms of the patterns of life in context.
