Abstract
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).
Results:
Participants’ mean age was 52.8 years, and 61.1% were female. MATCH-I demonstrated excellent internal consistency reliability (Cronbach’s alpha coefficient = 0.90) and significant correlations with IMFI-20 and BDI-II (all P < .05). Participants with HbA1c >7% and FBG >126 mg/dL had significantly lower MATCH-I scores (P < .05). 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.
