Abstract
OBJECTIVE: Although the psychometric properties of the Family Satisfaction with End-of-Life Care measure have been examined in diverse settings internationally; little evidence exists regarding measurement equivalence in Hispanic caregivers. The aim was to examine the psychometric properties of a short-form of the FAMCARE in Hispanics using latent variable models and place information on differential item functioning (DIF) in an existing family satisfaction item bank.
METHOD: The graded form of the item response theory model was used for the analyses of DIF; sensitivity analyses were performed using a latent variable logistic regression approach. Exploratory and confirmatory factor analyses to examine dimensionality were performed within each subgroup studied. The sample included 1,834 respondents: 317 Hispanic and 1,517 non-Hispanic White caregivers of patients with Alzheimer's disease and cancer, respectively.
RESULTS: There was strong support for essential unidimensionality for both Hispanic and non-Hispanic White subgroups. Modest DIF of low magnitude and impact was observed; flagged ...
