Effect of health literacy-based teach-back training on quality of life and treatment adherence in type 2 diabetes: an experimental study.

Education for patients with type 2 diabetes is an essential part of the treatment and control process. This study aimed to determine the effect of education based on health literacy strategies on adherence to treatment and quality of life in type 2 diabetic patients. This classic experimental study was performed on 94 patients with type 2 diabetes selected by convenient sampling method and then randomly allocated to intervention and control groups. The research instruments were a demographic information questionnaire, a Diabetes Quality of Life Brief Clinical Inventory, and an adherence to treatment questionnaire in patients with chronic disease. The educational intervention was five sessions of the virtual class of 80-90 min. All respondents completed the tools again two months after the intervention. Independent t-tests and paired t-tests were used for data analysis. The difference in the mean score of quality of life in the intervention group between the time before (53.21 ± 7.6) the intervention and two months after (55.28 ± 6.87) was statistically significant (p˂0.05). Comparison of the mean score of quality of life between the control and intervention groups, before the intervention (p > 0.05) and two months after (p > 0.05), neither showed a statistically significant difference. A comparison of the mean scores of adherence to treatment before (69.31 ± 5.32) and after the intervention (70.59 ± 5.21) showed that there was a statistically significant difference in the intervention group (p˂0.001). Comparison of the mean scores of adherence two months after the intervention revealed that, there is a significant statistical difference between the scores of the two groups (p˂ 0.001). Based on the findings of this study, it seems that providing training sessions based on health literacy strategies can improve the quality of life and adherence to treatment in patients with type 2 diabetes.
