the effect of training based on leventhal's self-regulatory model on the disease perception of diabetic adolescents

Background: people who have a correct understanding of their illness at the time of illness will be more sensitive to the related risk factors and will have more self-efficacy and ability. leventhal’s self-regulatory model as a cognitive-behavioral model plays an important role in disease management by increasing patient’s perception of the disease. therefore, this study was conducted with the aim of investigating the effect of education based on leventhal’s self-regulatory model on the disease perception of diabetic adolescents.method: this classical experimental study was conducted on 50 people who had been selected by simple random method in two intervention and control groups. the data collection tool was the disease perception questionnaire. the collected data entered into spss-21 statistical software to be analyzed by descriptive statistics (table, mean and standard deviation) and inferential statistics (paired t-test, independent t-test, ancova test).results: the covariance ancova test by removing the effect of pre-test showed a significant difference between the intervention and control groups (p=0.006 and eta=0.14), so that 14% of the post-test changes could be explained by the intervention.conclusion: leventhal’s self-regulatory model increased the disease perception of participants. therefore, based on this low-cost but effective non-pharmacological model, managers and health care workers can increase the disease perception, self-efficacy and self-care of diabetic patients.
