Establishing comparable measurement properties across different populations or in different population subgroups is a crucial yet often neglected step in instrument development. Failure to have comparable factor structures across groups makes any comparison between groups suspect. Previous analyses of the measurement structure of the Center for Epidemiologic Studies Depression Scale (CES-D) in diverse racial/ethnic populations have resulted in conflicting results. In the present analysis, data from three studies of urban Latinos (N = 1,403) were analyzed using structural equation modeling techniques to (1) fit the original four-factor solution separately in men and women; (2) evaluate configural and metric invariance between men and women; and (3) evaluate the mediating effects of age and acculturation on the fit of this model to the data. Results indicated that the four-factor model proposed by Radloff provided adequate fit to the data for Latina women when age and acculturation were included in the model. The four-factor model did not fit the data for Latino men; thus tests of configural and metric invariance across these two groups failed. We conclude that the CES-D may not measure the same constructs in Latino men and women and that further evaluation of the use of this measure in diverse populations is needed. Additionally, prior to comparison with other groups in which the four-factor solution is observed, the effects of age and acculturation should be controlled in Latinas.
在不同人群或不同人群亚组中建立可比的测量属性,是工具开发中关键但常被忽视的一步。未能在不同组间拥有可比的因子结构会使组间的任何比较都值得怀疑。先前对不同种族/族裔人群中流行病学研究中心抑郁量表(CES-D)测量结构的分析得出了相互矛盾的结果。在本分析中,使用结构方程建模技术对三项针对城市拉丁裔(N = 1403)的研究数据进行了分析,以(1)分别在男性和女性中拟合原始的四因素模型;(2)评估男性和女性之间的构型和度量不变性;(3)评估年龄和文化适应对该模型与数据拟合度的中介作用。结果表明,当模型中纳入年龄和文化适应因素时,Radloff提出的四因素模型对拉丁裔女性的数据拟合良好。四因素模型对拉丁裔男性的数据拟合不佳;因此,对这两组进行构型和度量不变性检验失败。我们得出结论,CES-D在拉丁裔男性和女性中可能测量的不是相同的结构,需要对该测量方法在不同人群中的使用进行进一步评估。此外,在与观察到四因素模型的其他组进行比较之前,应控制拉丁裔女性中年龄和文化适应的影响。
