改良后的功能全面评估（GAF）量表比原始GAF具有更详细的标准和更结构化的评分系统。 比较了两种量表的信度和效度。 具有不同培训水平的评定者从患者图表中分配入院和出院GAF评分。 与使用原始GAF的评定者（0.62）相比，使用改良GAF的评定者（0.81）的入院GAF评分的组内相关系数更高。 有效性研究显示两组分数之间存在高度相关性（0.80）。 改良的GAF也与Zung抑郁评分相关良好（-0.73）。 修改后的GAF可能是特别有用的，当评价者之间的可靠性需要最大化和/或当具有不同技能和就业背景的人-没有太多的GAF培训-必须率患者。 由于结构的增加，改良的GAF也可能更能抵抗评级者偏倚。
The modified Global Assessment of Functioning (GAF) scale has more detailed criteria and a more structured scoring system than the original GAF. The two scales were compared for reliability and validity. Raters who had different training levels assigned hospital admission and discharge GAF scores from patient charts. Intraclass correlation coefficients for admission GAF scores were higher for raters who used the modified GAF (0.81), compared with raters who used the original GAF (0.62). Validity studies showed a high correlation (0.80) between the two sets of scores. The modified GAF also correlated well with Zung Depression scores (-0.73). The modified GAF may be particularly useful when interrater reliability needs to be maximum and/or when persons with varying skills and employment backgrounds--and without much GAF training--must rate patients. Because of the increased structure, the modified GAF may also be more resistant to rater bias.
