The authors reviewed the acculturation literature with the goal of identifying measures used to assess acculturation in Hispanic populations in the context of studies of health knowledge, attitudes, and behavior change. Twenty-six acculturation measures were identified and summarized. As the Hispanic population continues to grow in the United States, there is a need to develop rigorous acculturation measures that include health indicators. Findings suggest that multidimensional acculturation scales are robust measurement tools when assessing nationality, cultural awareness, media and language preferences, and health status. Furthermore, aspects of Hispanic cultural lifestyle, such as beliefs about nutrition and physical activity, affect health care utilization, treatment, and prevention. Health communication researchers should consider aspects of cultural values and beliefs, and their impact on health status, for future research and health promotion interventions. (Contains 2 tables.)
