Psychometric Properties of the Indonesian Version of the Motivation and Attitudes Toward Health Change Scale and Its Role in Glycemic Outcomes in Type 2 Diabetes.

BACKGROUND: The Motivation and Attitudes Toward Changing Health (MATCH) scale is widely used to assess motivation and attitudes toward health behavior change. However, an Indonesian version of the MATCH (MATCH-I) has not yet been developed. OBJECTIVES: This study aimed to evaluate the psychometric properties of the MATCH-I and examine its association with glycemic control in type 2 diabetes. METHODS: A psychometric validation study was conducted with 90 adults with type 2 diabetes at a diabetes management center. Internal consistency reliability and test-retest reliability were evaluated using Cronbach's alpha coefficient and intraclass correlation coefficient. Criterion and convergent validity were assessed using Pearson correlations between MATCH-I and measures of fatigue (Indonesian version of the Multidimensional Fatigue Inventory [IMFI-20]) and depression (Beck Depression Inventory-Second Edition [BDI-II]). Known-group validity was examined by comparing MATCH-I scores across hemoglobin A1c (HbA1c) levels. Construct validity was assessed using exploratory factor analysis (EFA). Glycemic control was measured via HbA1c and fasting blood glucose (FBG). EFA supported a 3-factor structure: willingness to make changes, perceived ability to make or maintain changes, and feeling changes are worthwhile. CONCLUSIONS: The MATCH-I is a reliable and valid tool for assessing motivation and attitudes toward health change in Indonesian adults diagnosed with type 2 diabetes. It is associated with glycemic outcomes and is suitable for clinical and research applications in Indonesia.
