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 items related to information sharing. Only 1 item was flagged with significant DIF by both a primary and sensitivity method after correction for multiple comparisons "The way the family is included in treatment and care decisions." This item was more discriminating for the non-Hispanic, White responders than for the Hispanic subsample, and was also a more severe indicator at some levels of the trait; the Hispanic respondents located at higher satisfaction levels were more likely than White non-Hispanic respondents to report satisfaction. SIGNIFICANCE OFRESULTS:
The magnitude of DIF was below the salience threshold for all items. Evidence supported the measurement equivalence and use for cross-cultural comparisons of the short-form FAMCARE among Hispanic caregivers, including those interviewed in Spanish.Palavras-chave
