BACKGROUND
This paper seeks to compare group statistical analysis with effect size, group measures of clinical significance (Reliable Change Index and normative comparison), and individual analysis of clinical significance.
METHOD
Measures of variables important to parenting and child behavior improvement (Parenting Scale, Eyberg Child Behavior Inventory, and Parenting Stress Index [PSI]) were administered pre and post for a 9- to 10-week group Behavioral Parent Training Intervention. Analysis compares traditional group statistical significance testing with group measure of clinical significance and individual analysis of clinical significance.
RESULTS
All three measures demonstrated statistically significant differences from pre to post, with large effect sizes. Group measures of clinical significance, however, demonstrated meaningful change only on the PSI, while individual analysis showed improvements of 54% of participants at best and 0% at worst.
CONCLUSIONS
Individual analysis of clinical significance provides valuable information in treatment outcomes and should be included as a standard practice in outcomes research.
背景
本文旨在比较组间统计分析与效应量、临床意义的组间测量指标（可靠变化指数和常模比较）以及临床意义的个体分析。
方法
对9至10周的团体行为父母培训干预前后进行对养育和儿童行为改善重要的变量测量（养育量表、艾伯格儿童行为量表和养育压力指数[PSI]）。分析将传统的组间统计显著性检验与临床意义的组间测量指标和临床意义的个体分析进行比较。
结果
所有三项测量指标从干预前到干预后均显示出具有统计学显著性差异，且效应量较大。然而，临床意义的组间测量指标仅在PSI上显示出有意义的变化，而个体分析显示，参与者改善比例最高为54%，最低为0%。
结论
临床意义的个体分析为治疗结果提供了有价值的信息，应作为结果研究的标准做法纳入其中。
