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.
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.
The final version of the instrument has 70 items, 1 unifying construct, and 8 subscales. We found it to be valid and reliable (α=.93) for measuring the extent of occupational dysfunction and specific areas of strengths and weaknesses.
The LHQ is a promising new instrument, the first of its kind to measure occupational dysfunction in context for people with substance addictions.
我们开发并研究了生活方式史问卷（LHQ）的心理测量特性，这是一种自我报告工具，旨在测量因药物滥用导致的职业功能障碍程度。
该工具是根据职业治疗生态模型的概念以及威廉·L·怀特的研究成果开发的，怀特根据生活背景模式定义了成瘾文化。我们使用经典测试理论和项目反应理论对来自两项现场测试的数据进行了分析。
该工具的最终版本有70个项目、1个统一结构和8个子量表。我们发现它在测量职业功能障碍程度以及优势和劣势的特定领域方面是有效且可靠的（α = 0.93）。
LHQ是一种很有前景的新工具，是同类工具中首个用于测量成瘾者在实际情境中的职业功能障碍的工具。
