Background:
The Diabetes Obstacles Questionnaire-Short Version is a tool for measuring the quality of life in patients with diabetes mellitus. However, the validity and reliability of this tool has never been tested in Indonesia.
Purpose:
This study was designed to adapt and validate a Bahasa Indonesia version of the Diabetes Obstacles Questionnaire-Short Version for Indonesians with type 2 diabetes mellitus.
Methods:
This was a cross-sectional study. Data were collected from July to November 2023, and accidental sampling was used to recruit and enroll 1,116 participants. Convergence testing used the Diabetes Quality of Life questionnaire. The validity test used construct and convergent validities with significant Pearson correlations, and construct validity included exploratory factor analysis and confirmatory factor analysis. Reliability testing used Cronbach's alpha, composite reliability, and average variance extracted.
Results:
The results of the exploratory factor analysis showed nine factors with a factor loading per item of >.45, a Kaiser-Meyer-Olkin test score of .915, and significant Bartlett's test of sphericity results. The Cronbach's alpha value for all items was .930, and those of individual factors ranged from .730 to .848. The test-retest results with interclass correlation coefficients ranged from .910 to .973. The results of the confirmatory factor analysis indicate that this instrument has an acceptable model fit.
Conclusions/Implications For Practice:
The Bahasa Indonesia Diabetes Obstacles Questionnaire-Short Version produces valid and reliable results for measuring quality of life in people with type 2 diabetes mellitus in Indonesia. The sufficient but small number of items allows the questionnaire to be completed relatively quickly, making it useful in clinical settings. The subscales in this instrument may be used simultaneously or separately based on individual needs.
