The initial report of the Patterns of Individual Change Scales battery presented the rationale, development, and conceptualization of this measurement package. Empirical data supported the reliability and validity of the scales as measures of patient characteristics that extended beyond the symptomatic domain. This article presents more extensive reliability and validity data. Ratings on two new samples were collected, and the interrater reliability coefficients for the scales were again of appreciable magnitude. Discriminant validity was examined, as was the factor structure of the battery. The results suggested that the scales tap three distinct sources of variance. Comparisons with symptom measures and case illustrations indicated that the measurement of changes in patients' functioning beyond symptoms is necessary and viable.
个体变化量表组套的初始报告介绍了该测量工具包的基本原理、开发过程和概念化。实证数据支持这些量表作为衡量超出症状领域的患者特征的可靠性和有效性。本文展示了更广泛的可靠性和有效性数据。收集了两个新样本的评分，量表的评分者间信度系数再次达到可观的程度。检验了判别效度以及该组套的因子结构。结果表明这些量表挖掘了三个不同的方差来源。与症状测量和病例说明的比较表明，测量患者症状以外功能的变化是必要且可行的。
