OBJECTIVE
An empirical comparison of treatment efficacy estimates as based on psychometric measures of intra-individual change (Reliable Change methods).
METHOD
All seven different methods of assessing Reliable Change that have been advocated in the past two decades are compared empirically in a large in-patient sample (n = 107). Estimates of treatment efficacy by each of these seven Reliable Change methods are computed, using pre-/post-score changes on the Brief Psychiatric Rating Scale (BPRS).
RESULTS
It is demonstrated that Reliable Change methods may yield very different estimates of treatment efficacy. The Reliable Change method with the fewest statistical assumptions is one of the least sensitive Reliable Change methods.
CONCLUSION
Disagreement on the proper definition of Reliable Change is not merely of theoretical importance, but also has major practical implications.
目的
基于个体内变化的心理测量指标（可靠变化方法）对治疗效果估计值进行实证比较。
方法
在一个大型住院样本（n = 107）中对过去二十年来所倡导的评估可靠变化的所有七种不同方法进行实证比较。使用简明精神病评定量表（BPRS）的前后得分变化，计算这七种可靠变化方法中每种方法的治疗效果估计值。
结果
结果表明，可靠变化方法可能会得出非常不同的治疗效果估计值。统计假设最少的可靠变化方法是最不敏感的可靠变化方法之一。
结论
对可靠变化的恰当定义存在分歧不仅具有理论重要性，而且具有重大的实际意义。
