The Global Assessment of Functioning (GAF) is a quick and simple measure of overall psychological disturbance. However, there is little research on the reliability and validity of this measure in severely mentally ill populations.
Multidisciplinary keyworkers assessed 103 patients at monthly intervals over a 6-month period. Overall GAF scores were obtained, with additional separate ratings for symptoms and disability. These were compared with changes in antipsychotic medication and support needs over the same period.
Satisfactory reliability was obtained for total GAF score and for symptom and disability measures, in spite of raters having only one brief training session. All GAF scores were associated with current support needs of patients. Symptom and disability scores were associated with changes in antipsychotic medication in the previous month. Only symptom score was associated with increases in antipsychotic medication at time of rating.
GAF proved to be a reliable and, within the limits of the indicators used, a valid measure of psychiatric disturbance in our sample of the severely mentally ill. Differences in relationships between the three GAF scores and medication/support needs indicate the usefulness of obtaining all three scores for monitoring levels and type of psychiatric disturbance in this population.
功能总体评定量表（GAF）是一种快速简便的整体心理障碍测量方法。然而，关于该量表在严重精神疾病患者群体中的信度和效度研究较少。
多学科关键工作人员在6个月的时间里每月对103名患者进行评估。获得了GAF总分，以及症状和残疾的单独评分。将这些评分与同期抗精神病药物治疗的变化和支持需求进行比较。
尽管评分者只接受了一次简短的培训，但GAF总分以及症状和残疾测量的信度令人满意。所有GAF评分都与患者当前的支持需求相关。症状和残疾评分与前一个月抗精神病药物治疗的变化相关。只有症状评分与评分时抗精神病药物治疗的增加相关。
在我们的严重精神疾病样本中，GAF被证明是一种可靠的、在所用指标范围内有效的精神障碍测量方法。三个GAF评分与药物治疗/支持需求之间关系的差异表明，获取所有三个评分对于监测该群体精神障碍的水平和类型是有用的。
