ABSTRACT
Many studies show that the only way to control diabetes and prevent its debilitating complications is continuous self-care. This study aimed to determine factors affecting self-care behavior of diabetic women in Khoy City, Iran based the extended theory of reasoned action [ETRA]. A sample of 352 women with type 2 diabetes referring to a Diabetes Clinic in Khoy City in West Azarbaijan Province, Iran participated in the study. Appropriate instruments were designed to measure the relevant variables [diabetes knowledge, personal beliefs, subjective norm, self-efficacy and behavioral intention, and self-care behavior] based on ETRA. Reliability and validity of the instruments were determined prior to the study. Statistical analysis of the data was done using the SPSS-version 16 software. Based on the data obtained, the proposed model could predict and explain 41% and 26.2% of the variance of behavioral intention and self-care, respectively, in women with type-2 diabetes. The data also indicated that among the constructs of the model perceived self-efficacy was the strongest predictor for intention for self-care behavior. This construct affected both directly and indirectly self-care behavior. The next strongest predictors were attitudes, social pressures, social norms, and intervals between visiting patients by the treating team. The proposed model can predict self-care behavior very well. Thus, it may form the basis for educational interventions aiming at promoting self-care and, ultimately, controlling diabetes
