Measuring attitudes and health beliefs among Mexican Americans with diabetes.

Adherence to the treatment regimen for patients with diabetes is of major concern to healthcare practitioners, particularly when dealing with the high-risk, low-income, Mexican-American population. Assessing the attitudes and beliefs of this group is vital for planning effective and realistic intervention strategies. Therefore, we designed a culturally sensitive instrument to measure health beliefs and attitudes of low-income Mexican Americans with diabetes. The Health Belief Model (HBM) was used as a basis for this study because it is well accepted as a predictor of health-related behaviors. However, we found that the HBM was not an effective tool for assessing the health beliefs or attitudes of this patient population even after rigorous efforts to operationalize the HBM and after conducting extensive statistical analyses. Only two of the five subscales of the traditional HBM, barriers and benefits, were reliable. Scales to measure acculturation and fatalism were added to increase the cultural sensitivity of the tool. These added components were found to be an important variable in interpreting the results for low-income Mexican-American patients.
