Although the Global Assessment of Functioning (GAF) scale is a widely utilized instrument, little data on construct validity is available about its use with clients having schizophrenia. This study compared point-specific GAF scores with concurrent ratings of symptomatology and social and occupational impairments using the Functional Assessment Rating Scale (Ward & Dow, 1994). A linear multiple regression analysis of empirical data from investigations of clients' global functioning showed that increased work and school-related problems, danger to others, and psychotic symptoms predicted lower GAF scores. In general, GAF scores seem to reflect the construct of global psychological, social, and occupational functioning that the scale was designed to measure.
尽管全球功能评估（GAF）量表是一种广泛使用的工具，但关于其在精神分裂症患者中的结构效度的数据却很少。本研究使用功能评估量表（Ward & Dow，1994）将特定点的GAF分数与症状、社会和职业损害的同时期评分进行了比较。对患者整体功能调查的实证数据进行的线性多元回归分析表明，与工作和学校相关的问题增加、对他人的危险以及精神病症状预示着较低的GAF分数。总体而言，GAF分数似乎反映了该量表旨在测量的整体心理、社会和职业功能的结构。
