本研究采用项目反应理论(IRT)模型，在日本大学生样本中同时比较了Zung抑郁自评量表(SDS)、流行病学研究中心抑郁量表(CES-D)和病人健康问卷抑郁量表(PHQ-9)三种常用的自评抑郁量表在日本大学生样本中的心理测量特性。尽管这3个量表很可能测量相同的潜在结构--即抑郁--但在抑郁自评量表和CES-D中对消极措辞条目的选择并没有很好地发挥作用。与其他量表相比，CES-D在抑郁严重程度的范围内提供了更多的信息，从平均值到高于平均值的2个标准差，而PHQ-9为其他程度的抑郁提供了更多的信息。总体而言，PHQ-9的表现更好，因为它在最广泛的抑郁症严重程度范围内提供了比其他量表更多的信息，而且它没有包含无效选择的项目。在对抑郁症状水平升高的学生进行抽样时，CES-D也可能是一个很好的选择。最后，我们使用IRT分析得到的参数将三种工具在一个共同的量表上联系起来，并提供了一个人行横道表格来实现每个量表分数的转换。
We used an item response theory (IRT) model to simultaneously compare the psychometric properties of 3 commonly used self-report depression scales translated into Japanese-the Zung Self-Rating Depression Scale (SDS), the Center for Epidemiologic Studies Depression Scale (CES-D), and the Patient Health Questionnaire Depression Scale (PHQ-9)-in a Japanese university student sample. Although the 3 scales were likely to measure the same underlying construct-that is, depression-the choices of the negatively worded items in the SDS and CES-D did not function well. The CES-D provided more information than the other scales at the range of depression severity approximately from the mean through 2 standard deviations above the mean, while the PHQ-9 provided more information for the other degrees of depression. The PHQ-9 performed better as a whole, as it provided more information than the other scales on the broadest range of depression severity, and it did not contain items with inefficient choices. The CES-D may also be a good choice when sampling students with elevated levels of depressive symptoms. Finally, we linked the 3 instruments on a common scale using parameters derived from IRT analysis, and we provided a crosswalk table to enable the conversion of each scale score.
