Abstract
BACKGROUND: Proper evaluation of the generalizability of an instrument is critical for its use across different social contexts such as caregiver status. OBJECTIVE: To examine the differential item functioning of the Center for Epidemiologic Studies Depression (CES-D) Scale, patterns of response to each item of the CES-D Scale attributable to caregiver status was assessed. STUDY DESIGN: Using a cross-study comparison method, a sample of 58 matched pairs of Korean American caregivers and noncaregivers was used for matched moderated regression analysis on the CES-D Scale. RESULTS: The authors identified three items that vary according to caregiver status in the present study: Item 2 (My appetite was poor), Item 4 (I felt that I was as good as other people), and Item 14 (I felt lonely). CONCLUSIONS: Beyond assessing the level of depression through total CES-D scores, it is important to examine variations in the items of the CES-D Scale across different social contexts.
