There is a need for robust outcome measures for use in psychiatric services. Particularly lacking are self-rated recovery measures with evidence of sensitivity to change. This study was established to examine the convergent validity and sensitivity to change over time (responsiveness) of the Recovery Assessment Scale - Domains and Stages (RAS-DS), in comparison to level of unmet need as measured by the Camberwell Assessment of Need - Short Appraisal Scale (CANSAS). Convergent validity was examined through cross-sectional correlations between 540 CANSAS and RAS-DS scores collected on the same day for the same individuals. Sensitivity to change was examined using correlations between change scores in CANSAS and RAS-DS where both were collected on the same day and the two time points were separated by 90 days or more (n = 498). Results demonstrated moderate, significant cross-sectional correlations between CANSAS scores and RAS-DS total and domain scores and between change scores of both instruments. Results suggest that the RAS-DS is sensitive enough to detect change over time. Only moderate correlation between the RAS-DS and CANSAS suggests that, in the context of recovery-oriented service provision, it is important to measure self-reported recovery in addition to level of unmet needs.
在精神科服务中需要使用稳健的结果衡量标准。特别缺乏的是自我评估的恢复措施，这些措施具有对变化敏感的证据。本研究旨在检验恢复评估量表-领域和阶段（RAS-DS）的收敛有效性和随时间变化的敏感性（反应性），与通过坎伯韦尔需求评估-短期评估量表（CANSAS）衡量的未满足需求水平相比。通过在同一天为同一人收集的 540 份 CANSAS 和 RAS-DS 评分的横截面相关性来检验收敛有效性。通过比较同一天收集的 CANSAS 和 RAS-DS 的变化评分来检验敏感性，两个时间点之间间隔 90 天或更长时间（n=498）。结果表明，CANSAS 评分和 RAS-DS 总分和领域评分之间以及两个仪器的变化评分之间存在中度、显著的横截面相关性。结果表明，RAS-DS 足够敏感，可以检测随时间的变化。RAS-DS 和 CANSAS 之间只有中度相关性表明，在以恢复为导向的服务提供的背景下，除了未满足的需求水平外，衡量自我报告的恢复情况很重要。
