Roles of Attitudes and Intentions in Predicting Adherence to Oral Diabetes Medications
Originally Published In
The purpose of this quantitative study was to investigate the extent to which patient attitudes and intentions predict adherence to the use of oral antihyperglycemic regimens in African Americans. This cross-sectional study of 115 participants used correlation analysis to establish relationships among patient attitudes, intentions and adherence. Data analyses showed significant correlations between the variables. Multiple regression analysis was used to establish predictions between the variables. A prediction model containing attitudes, subjective norms and perceived behavioral control (PBC) explained 37% of the variance to behavioral intention. Intentions accounted for 8.5% of the variance to adherence. Attitudes predicted behavioral intentions. The findings support the theory of planned behavior model and identify important correlations between attitudes, intentions and behaviors. In addition, the results underscore the need for promoting positive attitudes and positive intentions in effective adherence to the use of oral antihyperglycemic regimens. Achieving adequate adherence through behavioral counseling can effect positive social change by reducing the mortality and morbidity that are associated with inadequate adherence to the use of oral diabetic agents.
