Self-report instruments of psychological symptoms are increasingly used in counseling centers but rely on rigorous evaluation of their clinical validity. Three studies reported here (total N = 26,886) investigated the validity of the Counseling Center Assessment of Psychological Symptoms-62 (CCAPS-62; Locke et al., 2011) as an assessment and screening instrument. In Study 1, initial evidence regarding the concurrent validity of the CCAPS-62 was replicated and extended in a naturalistic clinical sample of clients from 16 counseling centers. Using this sample, convergent validity of the subscales was examined in counseling center clients, the range of sensitivity of the subscales was investigated using item-response theory, and the presence of 2nd-order factors was preliminarily examined. In Study 2, 7 of the 8 CCAPS-62 subscales statistically significantly differentiated between students in counseling and those who were not, using data collected from a large national survey, although most differences were small and the groups' distributions overlapped considerably. Cut scores based on the differences between these clinical and nonclinical populations showed limited utility due to overall similarities between these broadly defined groups. In Study 3, therapist-rated diagnoses collected from 5 university counseling centers were used to further examine the validity of subscale scores. In addition, cut points for diagnostic screening using receiver operating characteristic curves were evaluated. Overall, these studies support the use of the CCAPS-62 as an initial measure of psychological symptoms in college counseling settings, provide additional information about its psychometric performance, develop cut scores, and illustrate the potential for collaboration between practitioners and researchers on a large scale.
自我报告的心理症状量表在咨询中心中越来越多地被使用，但需要对其临床有效性进行严格评估。这里报告的三项研究（共 26886 人）调查了咨询中心心理症状评估-62 量表（CCAPS-62；Locke 等人，2011）作为评估和筛查工具的有效性。在研究 1 中，对 CCAPS-62 的同时效度的初步证据进行了复制和扩展，纳入了来自 16 个咨询中心的自然临床样本中的客户。使用这个样本，在咨询中心客户中检查了子量表的收敛效度，使用项目反应理论研究了子量表的敏感性范围，并初步检查了二阶因素的存在。在研究 2 中，使用从大型全国调查中收集的数据，8 个 CCAPS-62 子量表中的 7 个在咨询学生和非咨询学生之间进行了统计学上的显著区分，尽管大多数差异较小，且这些群体的分布有很大重叠。基于这些临床和非临床群体之间的差异制定的分数切点由于这些广泛定义的群体之间的总体相似性而显示出有限的实用性。在研究 3 中，从 5 个大学咨询中心收集的治疗师评定诊断用于进一步检验子量表分数的有效性。此外，还评估了使用接收者操作特征曲线进行诊断筛查的切点。总体而言，这些研究支持在大学咨询环境中使用 CCAPS-62 作为心理症状的初始测量工具，提供了关于其心理计量学性能的更多信息，制定了分数切点，并说明了从业者和研究人员之间在大规模合作的潜力。
