AIM: The study was carried out to investigate the effect of tele-nursing based motivational interviewing on diabetes self-efficacy, self-management, and metabolic control parameters in individuals with Type 2 diabetes. METHOD: A parallel-group randomized controlled trial. The study was completed with 70 participants (intervention: 36
control: 34). The data were collected using the Socio-demographic and Health Related Questionnaire, the Diabetes Self-Efficacy Scale, the Diabetes Self-Management Scale. The intervention group received eight sessions tele-nursing based motivational interviewing. Instruments were administered to both groups before the intervention, at the end of the last motivational interviewing session (post-test, 3rd-month), and at 6th-month follow-up. The data were analyzed using chi-square test, independent sample t-test, and one-way ANOVA. RESULTS: In the pre-test, there was no difference between the intervention and control groups in terms of independent variables (p >
0.05). Self-efficacy and self-management scores increased in the post-test and follow-up test of the group to which telenursing-based MI was applied, and there was a difference between the groups (p <
0.05). FBG and triglyceride levels of the intervention group decreased significantly in the post-test and follow-up test (FBG = 217.46 ± 73.88, 166.13 ± 50.71, and 161.41 ± 50.50, respectively
triglyceride = 225.28 ± 148.32, 159.68 ± 68.62, and 161.09 ± 73.06, respectively) (p <
0.05). HbA1c% level decreased significantly only in the post-test. However, no significant differences were found in terms of other metabolic parameters (p >
0.05). CONCLUSIONS: This result shows the positive effectiveness of tele-nursing based MI intervention on self-efficacy, self-management, HbA1c%, FBG, triglyceride. Public health nurses should be provided with tele-nursing based MI to individuals with type 2 diabetes in primary health care institutions.
