The effect of information, motivation and behavioural skills model-based Diabetes Education and Motivational Interview Program on health outcomes in middle-aged adults with type 2 diabetes: a randomised controlled study.

Abstract

Background: Many models and theories are used to increase the self-management of individuals with type 2 diabetes. This study aims to examine the effect of information, motivation, behavioural skills (IMB) model-based diabetes education and motivational interviewing program on health belief, self-efficacy, self-management, and metabolic control in adults with type 2 diabetes.

Method: The study is a single-blind, randomised controlled trial. The study was conducted between 2021 and 2022 with intervention (n = 30) and control groups (n = 30). The intervention group applied the diabetes education and motivational interviews program for 12 weeks that was created based on the IMB model. The study data were collected with a socio-demographic questionnaire, Diabetes Knowledge Scale, Health Belief Scale, Self-Efficacy Scale, and Self-Management Scale.

Results: In the post-test and follow-up measurements, the mean scores of the intervention group on the knowledge, health belief, self-efficacy, and self-management scale were significantly higher than those of the control group, while the HbA1c% and body mass index (BMI) values of the intervention group showed a significant decrease over time. However, there was no difference between the groups in the post-test BMI and HbA1c% values.

Conclusion: The nurse-led intervention was found to be effective in increasing information, health belief, self-efficacy, self-management, and decreasing HbA1c%, BMI in adults with type 2 diabetes.

Study registration: The study was registered in ClinicalTrials NCT05030844.
