The Effect of Motivational Interviewing With Video Call in Individuals With Type 2 Diabetes:RCT


This study will be carried out to examine the effect of motivational interviewing applied by video call on diabetes self-efficacy, diabetes self-management and metabolic control parameters (HbA1c%, BMI, fasting glucose, cholesterol, blood pressure, waist circumference) in individuals with type 2 diabetes.

Clinical Trial Outcome Measures

Primary Measures

  • Diabetes Self-Efficacy Scale
    • Time Frame: Change from Baseline diabetes self-efficacy at 6 months
    • The change in diabetes self efficacy of individuals with Type 2 diabetes at 3rd month and 6 rd month with the Diabetes Self-Efficacy Scale.
  • Diabetes Self-Management Scale
    • Time Frame: Change from Baseline diabetes self-management at 6 months
    • This scale was used to measure the behavioral component of individuals in the IMB model. The validity and reliability study of the Turkish Diabetes Self-Management Perception Scale was conducted by Eroğlu and Sabuncu (2018). The scale consists of 16 items and 4 sub-dimensions and is a 4-point Likert type. Glucose Management sub-dimension: Items 4, 6, 10, 12 (items 4 and 12 are about drug use, items 1, 6 and 10 are about blood glucose monitoring). Diet Control sub-dimension: Items 2, 5, 9, 13. Physical Activity sub-dimension: Items 8, 11, 15. Use of Health Services sub-dimension: It consists of 3, 7, 14, and 16 items. The DMS scale consists of 16 items, 7 of which are straight and 9 of which are reversed. The scores of the items numbered “5, 7, 10, 11, 12, 13, 14, 15 and 16” in the scale are calculated by reversing them. Diabetes self-management increases as the score gets closer to 10.

Secondary Measures

  • HbA1c%
    • Time Frame: Change from Baseline HbA1c% at 6 months
  • Body Mass Index
    • Time Frame: Change from Baseline Body Mass Index at 6 months
  • Fasting glucose
    • Time Frame: Change from Baseline Fasting glucose at 6 months
  • Cholesterol
    • Time Frame: Change from Baseline Cholesterol at 6 months
  • waist circumference
    • Time Frame: Change from Baseline waist circumference at 6 months
  • Blood pressure
    • Time Frame: Change from Baseline blood pressure % at 6 months
