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. We analyzed data from two
field tests using both classical test theory and item response theory. RESULTS:
The final version of the instrument has 70 items, 1 unifying construct, and 8
subscales. We found it to be valid and reliable (alpha = .93) for measuring the
extent of occupational dysfunction and specific areas of strengths and
weaknesses. CONCLUSION: The LHQ is a promising new instrument, the first of its
kind to measure occupational dysfunction in context for people with substance
addictions.
