The validity and reliability of the Indonesian version of the Diabetes Mellitus Self-Efficacy Scale (DMSES-I).

BACKGROUND

The incidence of diabetes mellitus (DM) and its complications is increasing in Indonesia. The patient's quality of life will decrease due to this condition. Diabetes self-management is a viable tactic for improving quality of life and reducing blood sugar levels. A key element of diabetes self-management education for nurses and health professionals is self-efficacy. However, a valid and reliable scale to assess self-efficacy in Indonesia is necessary.

AIMS

'The Diabetes Mellitus Self-Efficacy Scale (DMSES)' is translated into Indonesian for the psychometric assessment of diabetes patients there.

METHOD

DMSES was translated into the Indonesian version (DMSES-I) using the forward-backward translation method. In addition, 227 adult patients with type 2 diabetes completed the scale which underwent internal consistency, construct validity and content validity tests.

RESULTS

The item content validity and scale validity were 0.955 and 0.955, respectively. Exploratory factor analysis showed a Kaiser-Meyer-Olkin index of 0.922 and a Cronbach's alpha coefficient of 0.928. The confirmatory factor analysis results were chi-square = 76.610, probability = 0.009 and root mean square error of approximation (RMSEA) = 0.049.

CONCLUSION

To assess diabetes self-efficacy in Indonesia, the DMSES-I is a valid and reliable tool. To educate diabetes self-management effectively, nurses must assess their patients' diabetes self-efficacy.
