The authors conducted two studies to address issues of the dimensionality, scale reliability, and psychometric properties of scores on the Reynolds Adolescent Depression Scale-Second Edition (RADS-2; Reynolds, 2002) in samples of adolescent psychiatric inpatients. In Study 1 (N=262), they used bifactor analysis to further evaluate the general and specific components of the RADS-2. In Study 2 (N=196), they used confirmatory factor analysis to evaluate the fit of a 1-factor model, the original 4-factor model, a second-order model, and a bifactor model to a new sample data. In both studies, the total RADS-2 and content-specific subscale scores showed acceptable estimates of reliability (i.e., scale reliability estimates >.80). Estimates of concurrent validity were also examined. Scores of the RADS-2 total and content-specific subscale scores were useful in differentiating between the responses of youth with mood disorder diagnoses and those with other primary psychiatric disorder diagnoses. The authors also conducted correlation analyses to identify potential correlates for the total RADS-2 scale and the proposed subscale scores.
作者进行了两项研究，旨在解决雷纳氏青少年抑郁量表第二版（RADS-2；雷纳，2002）在青少年精神病住院患者样本中的维度、量表可靠性和心理测量特性问题。在研究 1（N=262）中，他们使用双因素分析进一步评估 RADS-2 的一般和特定成分。在研究 2（N=196）中，他们使用验证性因子分析评估一个 1 因素模型、原始 4 因素模型、二阶模型和双因素模型对新样本数据的拟合情况。在这两项研究中，RADS-2 的总分和内容特定子量表得分显示出可接受的可靠性估计值（即，量表可靠性估计值>.80）。还检验了同时效度的估计值。RADS-2 的总分和内容特定子量表得分有助于区分有心境障碍诊断的青少年和有其他主要精神障碍诊断的青少年的反应。作者还进行了相关分析，以确定 RADS-2 总分和拟议的子量表得分的潜在相关因素。
