使用基于学校（N = 1，060）和临床参考（N = 303）的青年样本，作者使用Schmid-Leiman探索性双因素分析开发了修订的儿童焦虑和抑郁量表（RCADS）的25项缩短版本，以减少客户负担和管理时间，从而改善这种青年焦虑和抑郁测量的可移植性特征。结果显示，所有的焦虑项目主要反映了一个单一的“广泛的焦虑”的维度，这通知了减少15个项目的焦虑总量表的发展。虽然特定的DSM导向的焦虑子量表不包括在这个版本中，组成焦虑总量表的项目均匀地从原始RCADS的5个焦虑相关的内容域中提取。由此产生的15项焦虑总规模证明显着的对应关系与焦虑诊断组的基础上结构化的临床访谈。10项抑郁总量表（保留原始版本）的评分也与临床参考样本和学校样本中可接受的可靠性相关（α = 0.80和0.79，分别）;这与Muris先前开发的替代5项缩短RCADS抑郁总量表相反。Meesters和Schouten（2002），证明抑郁评分的可靠性不可接受（α = .63）。因此，本研究中开发的缩短的RCADS平衡了效率，广度和量表评分的可靠性，这种方式可能有助于临床环境中的重复测量以及评估焦虑和抑郁问题的大规模筛查。这些未来的应用进行了讨论，继续使用探索性双因素建模规模发展的建议。
Using a school-based (N = 1,060) and clinic-referred (N = 303) youth sample, the authors developed a 25-item shortened version of the Revised Child Anxiety and Depression Scale (RCADS) using Schmid-Leiman exploratory bifactor analysis to reduce client burden and administration time and thus improve the transportability characteristics of this youth anxiety and depression measure. Results revealed that all anxiety items primarily reflected a single "broad anxiety" dimension, which informed the development of a reduced 15-item Anxiety Total scale. Although specific DSM-oriented anxiety subscales were not included in this version, the items comprising the Anxiety Total scale were evenly pulled from the 5 anxiety-related content domains from the original RCADS. The resultant 15-item Anxiety Total scale evidenced significant correspondence with anxiety diagnostic groups based on structured clinical interviews. The scores from the 10-item Depression Total scale (retained from the original version) were also associated with acceptable reliability in the clinic-referred and school-based samples (alpha = .80 and .79, respectively); this is in contrast to the alternate 5-item shortened RCADS Depression Total scale previously developed by Muris. Meesters, and Schouten (2002), which evidenced depression scores of unacceptable reliability (alpha = .63). The shortened RCADS developed in the present study thus balances efficiency, breadth, and scale score reliability in a way that is potentially useful for repeated measurement in clinical settings as well as wide-scale screenings that assess anxiety and depressive problems. These future applications are discussed, as are recommendations for continued use of exploratory bifactor modeling in scale development.
