OBJECTIVE
The Recovery Assessment Scale (RAS) is one of the most used recovery measures in recovery-oriented practice evaluation of people with mental health conditions. Although its psychometric properties have been extensively studied, one critical piece of information that is missing from the literature is evidence of its longitudinal factorial invariance-that is, whether the RAS measures the same recovery construct across time. The authors empirically tested the longitudinal factorial invariance assumption for the RAS.
METHODS
Structural equation modeling was used to test the longitudinal factorial invariance of the RAS with data longitudinally obtained at three time points from 167 people with severe mental illness.
RESULTS
The longitudinal factorial invariance assumption was supported (i.e., configural, metric, partial scalar, factor variance and covariance invariance).
CONCLUSIONS
This study found empirical evidence that the RAS can measure the same recovery construct over time and thus meets one of the important prerequisites for longitudinal assessment.
目的
康复评估量表（RAS）是康复导向实践评估心理健康状况人群康复的最常用测量方法之一。尽管其心理测量特性已经得到广泛研究，但文献中缺少一个关键信息，即缺乏其纵向因子不变性的证据，也就是说，RAS 是否在跨时间测量相同的康复结构。作者通过从 167 名严重精神疾病患者处获得的三个时间点的纵向数据，实证检验了 RAS 的纵向因子不变性假设。
方法
结构方程模型用于检验 RAS 的纵向因子不变性假设，从 167 名严重精神疾病患者处获得的三个时间点的纵向数据。
结果
纵向因子不变性假设得到支持（即，组态、度量、部分标度、因子方差和协方差不变性）。
结论
本研究发现，RAS 可以随着时间测量相同的康复结构，因此满足纵向评估的一个重要前提条件。
