The Global Assessment of Functioning (GAF) scale is a quick and simple measure of overall psychological disturbance. A recent study by our group reported the reliability and validity of the scale in a population of severely mentally ill people. The current study extends the analysis of this population to consider a number of questions, i.e. what are the associations for this group between variations in GAF scores and sociodemographic variables? Are lower scores associated with particular diagnoses for the group assessed? What are the characteristics of those patients whose scores were most variable? What were the completion rates for use of the scale? No associations were observed between GAF score and the sociodemographic variables used in this study. Lower GAF scores were associated with psychotic diagnoses. Those with most varying scores were, in the main, white European non-immigrant males with a diagnosis of schizophrenia. Completion rates for the study were reasonable at 73.8%. This study involved the repeated assessment of a large number of clients by a changing multidisciplinary team. Inspite of the extended nature of the study, completion rates remained reasonable, suggesting that the scale was acceptable for routine clinical use. The GAF in itself, however, appears to be unsuitable for making individual treatment decision but could be used as a first step before using more sophisticated scales.
全球功能评估（GAF）量表是一种快速、简便的整体心理障碍测量方法。我们团队最近的一项研究报告了该量表在重度精神疾病患者群体中的信度和效度。当前的研究将对这一群体的分析进行扩展，以考虑一些问题，即对于该群体而言，GAF分数的变化与社会人口统计学变量之间有哪些关联？较低的分数是否与所评估群体的特定诊断相关？分数变化最大的那些患者有哪些特征？该量表的使用完成率是多少？在本研究中，未观察到GAF分数与社会人口统计学变量之间存在关联。较低的GAF分数与精神病性诊断相关。分数变化最大的主要是患有精神分裂症诊断的欧洲非移民白人男性。该研究的完成率为73.8%，较为合理。这项研究涉及由不断变化的多学科团队对大量服务对象进行重复评估。尽管研究范围有所扩大，但完成率仍然合理，这表明该量表可用于常规临床应用。然而，GAF量表本身似乎不适合用于做出个体治疗决策，但可在使用更复杂的量表之前作为第一步使用。
