Demographic characteristics do not decrease the utility of depressive symptoms assessments: examining the practical impact of item bias in four heterogeneous samples of older adults

Abstract: Objective Previous studies have identified differential item function (DIF) in depressive symptoms measures, but the impact of DIF has been rarely reported. Given the critical importance of depressive symptoms assessment among older adults, we examined whether DIF due to demographic characteristics resulted in salient score changes in commonly used measures. Methods Four longitudinal studies of cognitive aging provided a sample size of 3,754 older adults, and included individuals both with and without a clin… Show more

“…We also assessed the impact of the other covariates that are commonly found to be associated with depressive symptoms in other research with this population ( Dmitrieva et al, 2015 ; Parajuli, Berish, & Jao, 2019 ). Each of the models in Table 3 was compared with a model containing all of the other potential variables (sex, age, number of comorbid conditions, and MMSE scores) using AIC and BIC fit criteria.…”

“…The Center for Epidemiologic Studies Depression Scale (CES-D) is a well-used depression screening tool with psychometric properties that are not significantly influenced by age, cognitive or physical impairment, disease, or gender when used with community-dwelling older adults (Dmitrieva et al, 2015; Lewinsohn, Seeley, Roberts, & Allen, 1997). It provides ranges of scores that correspond with degrees of likelihood of clinical depression (Courtin, Knapp, Grundy, & Avendano-Pabon, 2015; Haringsma, Engels, Beekman, & Spinhoven, 2004; Lewinsohn et al, 1997; Radloff, 1977).…”

“…DIF occurs when groups (such as defined by sex, ethnicity, age, or education) have different probabilities of endorsing a given item after controlling for overall scores. We plan to examine and adjust our scores for DIF in future studies, especially across ethnicity (e.g., MAP and MARS), and adjust for it if it turns out to be impactful (Crane et al, 2007; Dmitrieva et al, 2015).…”
