目的：目的是调查精神疾病诊断和统计手册（DSM）第四版中功能总体评估（GAF）的症状和功能维度的有效性和临床影响。是否需要对DSM第五版进行修订？材质：样本包括2695名患者，他们从1998年到2007年连续入住14个不同的治疗单位，参加挪威以个性为中心的治疗计划网络。GAF的症状和功能维度的收敛和判别效度通过其与人口统计学变量、诊断状态和其他评估症状困扰、人际关系问题、工作和社会功能障碍，和生活质量。结果：GAF的各个维度的有效性得到证实的判别和并发协会，以其他相关的临床措施。然而，传统的GAF测量的基础上，无论是症状或功能水平的较低的分数被发现，以及作为一个全球性的指标的症状困扰和社会功能障碍。GAF的症状和功能评分之间的显着差异被发现在约10%的情况下，当差异被发现，功能障碍往往更严重。结论：本研究证实了2 GAF尺寸的有效性。然而，这些维度之间的实质性差异很少发生。因此，我们建议在DSM第五版中延长GAF量表，大致与DSM第四版相同。(C)2012 Elsevier Inc.

Objective: The objective was to investigate the validity and clinical impact of the symptom and function dimensions of the Global Assessment of Functioning (GAF) in the Diagnostic and Statistical Manual of Mental Disorders (DSM), Fourth Edition. Is there any need for revision with respect to the DSM, Fifth Edition?Material: The sample comprised 2695 patients consecutively admitted to 14 different treatment units participating in the Norwegian Network of Personality-Focused Treatment Programs from 1998 to 2007.Methods: Convergent and discriminant validity of the symptom and function dimensions of GAF was analyzed by their associations with demographic variables, diagnostic status, and other self-reported variables assessing symptom distress, interpersonal problems, work and social impairment, and quality of life.Results: The validity of the separate GAF dimensions was confirmed by discriminant and concurrent associations to other relevant clinical measures. However, the traditional GAF measure based on the lower score of either symptom or function level was found to serve well as a global indicator of symptom distress and social dysfunction. A substantial difference between the symptom and function score of GAF was found in about 10% of the cases; and when differences were found, functional impairment was most often more severe.Conclusion: This study confirms the validity of the 2 GAF dimensions. However, substantial differences between these dimensions are rarely occurring. We therefore recommend that the GAF scale be prolonged in the DSM, Fifth Edition, roughly in the same shape as in the DSM, Fourth Edition. (C) 2012 Elsevier Inc. All rights reserved.
