OBJECTIVE
The Global Activity Limitation Indicator (GALI), a single question measuring disability, had been introduced in various European surveys since 2004. The complexity of its wording has been questioned. Our study compares alternative variants aiming to simplify the wording.
METHOD
We used the Health-Related Opinion Survey run in 2014 in France (N = 3,009). Its split sample design allows testing four variants of the questions. We analyzed the prevalence of activity limitation (AL) resulting from the four different constructs of the GALI using multinomial logistic regressions, adjusted for background variables and functional limitations (FLs).
RESULTS
The alternative GALI variants result in significantly different prevalences compared with the original question, in particular for people with FL. The current variant is more inclusive than the routed variants.
DISCUSSION
Our study suggests limited benefits of changing the GALI construct which do not outweigh the costs of breaking the established chronological series of the current variant.
目的
全球活动受限指标（GALI）是一个用于衡量残疾情况的单一问题，自2004年起已被引入各种欧洲调查中。其措辞的复杂性受到了质疑。我们的研究比较了旨在简化措辞的替代变体。
方法
我们使用了2014年在法国进行的健康相关意见调查（N = 3,009）。其拆分样本设计允许测试该问题的四种变体。我们使用多项逻辑回归分析了由GALI的四种不同结构导致的活动受限（AL）患病率，并对背景变量和功能受限（FL）进行了调整。
结果
与原始问题相比，替代的GALI变体导致的患病率有显著差异，特别是对于有FL的人群。当前变体比常规变体更具包容性。
讨论
我们的研究表明，改变GALI结构的益处有限，且不足以抵消打破当前变体既定时间序列的成本。
