The characteristics of ADL indices which provide a total score of disability or capability are described, and the complexity of their rationale is stressed. The technical requirements of a good index in terms of reproducibility and validity are then discussed. It is suggested: (i) that there are some good validated indices available which, within limits, provide reproducible scores; (ii) that until demonstrably better indices are available, more suited to the local national context, workers should use these indices when they need total scores, in preference to devising their own.
描述了提供残疾或能力总分的日常生活活动（ADL）指数的特征，并强调了其原理的复杂性。接着讨论了一个好的指数在可重复性和有效性方面的技术要求。建议如下：（i）有一些经过良好验证的指数，在一定范围内可提供可重复的分数；（ii）在有更适合当地国情的、明显更好的指数可用之前，工作人员在需要总分时应使用这些指数，而不是自行设计。
