This study entails the use of meta-analytic techniques to calculate and analyze 18 independent and 52 nonindependent effect sizes across 17 published studies of psychological assessment as a therapeutic intervention. In this sample of studies, which involves 1,496 participants, a significant overall Cohen's d effect size of 0.423 (95% CI [0.321, 0.525]) was found, whereby 66% of treatment group means fell above the control and comparison group means. When categorical variables were taken into account, significant treatment group effects were found for therapy process variables (d = 1.117, [0.679, 1.555]), therapy outcomes (d = 0.367, [0.256, 0.478]), and combined process/outcome variables (d = 0.547, [0.193, 0.901]). These findings appear to be robust on the basis of fail-safe N calculations. Taken together, they suggest that psychological assessment procedures-when combined with personalized, collaborative, and highly involving test feedback-have positive, clinically meaningful effects on treatment, especially regarding treatment processes. They also have important implications for assessment practice, training, and policy making, as well as future research, which are discussed in the conclusion of the article.
本研究采用元分析技术，对 17 项已发表的心理评估治疗干预研究中的 18 个独立和 52 个非独立效应量进行计算和分析。在这项涉及 1496 名参与者的研究样本中，发现了一个显著的整体 Cohen's d 效应量为 0.423（95%CI [0.321, 0.525]），其中 66%的治疗组平均值高于对照组和比较组平均值。当考虑分类变量时，发现治疗过程变量（d = 1.117，[0.679, 1.555]）、治疗结果（d = 0.367，[0.256, 0.478]）和综合过程/结果变量（d = 0.547，[0.193, 0.901]）具有显著的治疗组效应。根据失效安全 N 计算，这些发现似乎是稳健的。总的来说，它们表明心理评估程序——与个性化、协作和高度参与的测试反馈相结合——对治疗具有积极的、有临床意义的影响，特别是在治疗过程方面。它们对评估实践、培训和政策制定以及未来的研究也具有重要意义，这些都在文章的结论中进行了讨论。
