RESUMEN
Reliability and validity evidence is provided for the Demographic Index of Cultural Exposure (DICE), consisting of six demographic proxy indicators of acculturation, within two community samples of Mexican-origin adults (N= 497 for each sample). Factor analytic procedures were used to examine the common variance shared between the six demographic indicators hypothesized to correlate with acculturation. The index was cross-validated across two samples by comparing fit indices. Finally, index criterion validity was assessed using correlations between index scores and five common behavioral/psychological domains of Latino cultural identity: language use (Spanish and English), cultural practices, folk health beliefs, and fatalism. Results indicated that the six demographic indicators loaded onto one latent factor and that this model had good fit across both samples. In addition, DICE scores correlated with four of the five behavioral/psychological measures. Future use of the DICE as an efficient way to approximate cultural exposure is discussed.
RESUMEN
An understanding of health beliefs is key to creating culturally appropriate health services for Hispanic populations in the US. In this study we explore age-based variations in causal beliefs for heart disease and diabetes among Mexican origin adults in Houston, TX. This cross-sectional study included 497 adults of Mexican origin. Participants were asked to indicate the importance of biomedically defined and folk illness-related risk factors as causes for heart disease and diabetes. Biomedical risk factors were ranked highest as causes of diabetes and heart disease among all participants. Folk illness-related factors were ranked below biomedical factors as causes of heart disease among all age groups. Susto was ranked above the median as a risk factor for diabetes among older participants. Age-related differences in causal beliefs may have implications for designing culturally appropriate health services, such as tailored diabetes interventions for older Mexican origin adults.
