ABSTRACT
Objective[s]: A far-reaching body of the literature highlights that continuous performing of diabetes self-management behaviors is effective on diabetics. Nowadays among self-care behaviors, physical activity is the most important behavior that influences diabetes control. This study aimed to understand and predict physical activity behavior based on the extended theory of reasoned action among women with type 2 diabetes, in Khoy located in Western North of Iran
Methods: An eligible sample of 352 women with type 2 diabetes, referring to a Diabetes Clinic and the Charity Foundation for Diabetes Disease participated in the study. Appropriate instruments were designed to measure the variables of interest [diabetes knowledge, personal beliefs, subjective norm, self-efficacy and behavioral intention along with physical activity behavior]. Reliability and validity of the instruments were examined and approved. Statistical analyses of study were conducted by SPSS package
Results: The findings of investigation indicated that there exists a statistical significant correlation among independent constructs of proposed model with Model-related dependent variables, as among constructs of model, self-efficacy was the strongest predictor of intentions among women with type 2 diabetes. This construct both directly and indirectly affected physical activity behavior. In addition to self efficacy, diabetics' physical activity also is influenced by other variables of model and sociodemographic factors
Conclusion: Our findings suggest the high ability of the extended theory of reasoned action with self-efficacy in forecasting and explaining physical activity can be a base for educational intervention. Thus, for improving diabetics' physical activity behavior and finally controlling the disease, using educational interventions based on proposed model are necessary
ABSTRACT
Objective[s]: To determine the effect comparison of self efficacy[S-E] and perceived behavioral control [PBC] on Theory of Reasoned Action prediction in substance abuse avoidance by path analysis. [By Lisrel software]. Therefore PBC and S-E were added to Theory of Reasoned Action. Then It was compared the model fitness and prediction percentage of intention and behavior by Theory of Reasoned Action and the other it's versions
Methods: Validity and reliability of questionnaires were assessed and data were collected from 433 high school students [15-19 years-sons] on the various components of models. Then it was compared fitness indices and percentage of intention and behavior prediction by path analysis between TRA and other it's developed versions
Results: The results indicated that fitness indices and percentage of intention and behavior prediction by the Theory of Reasoned Action in substance abuse avoidance were become well by PBC and S-E. This effect had a minimum rate in version with PBC and a maximum rate in version with SE. in addition SE was more effective than PBC in this effectiveness especially on intention prediction rate
Conclusion: The results of this study indicated PBC and S-E were increased the Reasoned Action Theory effective in substance abuse avoidance
