The focus on recovery, not just symptom reduction, in mental health care brings a need for psychometrically sound measures of recovery. This study examined the factor structure and sensitivity to change of a common measure of mental health recovery, the Recovery Assessment Scale (RAS). We conducted a secondary data analysis from a randomized clinical trial of self-management for depression (n = 302). We tested both bifactor and the previously found five-factor model. Sensitivity to change was examined three ways: (1) between the intervention and control group; (2) across time in the intervention group; and (3) in those whose depression remitted. The previous five-factor model was supported. One subscale, no domination by symptoms, was particularly sensitive to change and showed sensitivity to change whereas the subscale reliance on others did not show change in any of the comparisons. Results suggest that the subscales of the RAS should be examined separately in future studies of recovery.
心理健康护理中对康复的关注，而非仅仅是症状减轻，这带来了对心理测量学上可靠的康复测量方法的需求。本研究考察了心理健康康复常用测量工具——康复评估量表（RAS）的因子结构及对变化的敏感性。我们对一项抑郁症自我管理随机临床试验（n = 302）进行了二次数据分析。我们测试了双因子模型以及先前发现的五因子模型。从三个方面考察了对变化的敏感性：（1）干预组与对照组之间；（2）干预组随时间的变化；（3）抑郁症缓解者的情况。先前的五因子模型得到了支持。一个子量表，即不受症状主导，对变化特别敏感且显示出变化，而依赖他人子量表在任何比较中均未显示出变化。结果表明，在未来的康复研究中应分别考察RAS的各个子量表。
