Few studies of the validity of the Global Assessment of Functioning (GAF) have been published and none has shown how GAF ratings are associated with concurrent ratings of symptoms and social functioning. This article provides such data.
Patients suffering from schizophrenia were assessed at admission to hospital and at six- and 12-month follow-up, using the GAF, the Scale for the Assessment of Positive Symptoms (SAPS), the Scale for the Assessment of Negative Symptoms (SANS) and the Social Behaviour Schedule.
GAF ratings were highly correlated with ratings of symptoms and social behaviour at both follow-ups but not at initial assessment, although the inter-rater reliabilities for the measures were good.
The GAF can be rated reliably after minimal training. It provides a valid summary of symptoms and social functioning among schizophrenic patients provided they are not assessed when suffering from acute psychotic episodes.
关于功能总体评定量表（GAF）有效性的研究发表较少，且尚无研究表明GAF评分与症状及社会功能的同期评分之间的关联。本文提供了此类数据。
使用GAF、阳性症状评定量表（SAPS）、阴性症状评定量表（SANS）及社会行为量表，对精神分裂症患者在入院时、随访6个月及12个月时进行评估。
在两次随访时，GAF评分与症状及社会行为评分高度相关，但在初次评估时并非如此，尽管这些测量方法的评定者间信度良好。
经过最少的培训后，GAF能够得到可靠的评分。它能有效总结精神分裂症患者的症状及社会功能，前提是在急性精神病发作时不进行评估。
