The Effect of Educational Intervention Based on PRECEDE Model on Improving Self-care Behaviors of Diabetic Elderly

 Improper lifestyle and unfavorable self-care in diabetic patients have led to the emergence and spread of complications and problems caused by the burden of the disease. This study was conducted with the aim of determining the effect of an educational intervention based on the PRECEDE model on improving the self-care behaviors of diabetic elderly.

 This is a semi-experimental study that was conducted on 200 elderly people with diabetes referring to Fasa diabetes centers in 2019-2020. The experimental group was trained in self-care skills based on the PRECEDE model in 6 training sessions of 50-55 minutes. Before and after the intervention, the self-care behaviors of the patients and the constructs of the PRECEDE model were measured in both groups using questionnaires. After entering the SPSS version 20 software, the data were analyzed using independent t-test, paired t-test and chi-square test.

 In the experimental group, the average score of their self-care behaviors increased significantly from 101.31±36.2 to 139.01±35.8 (P<0.001), also in the experimental group, the mean scores of all constructs of the PRECEDE model increased significantly after the intervention (P<0.05). In the control group, there was no significant change in the average score of the constructs of the PRECEDE model and self-care behaviors before and after the intervention (P>0.05).

 The results of the study indicated the effectiveness of the educational program based on the PRECEDE model on improving the self-care behaviors of the elderly with diabetes.
