Abstract

Objectives: To explore the content validity and the internal consistency of the diabetes Self-management Questionnaire (DSMQ) for persons with T2DM in Thailand.

Methods: Diabetes Self-management Questionnaire (DSMQ) was developed in English. The translation of DSMQ into Thai language was performed by native Thai translators. A panel of five experts in Thailand evaluated the translation. Content validity was quantified by the content validity index (CVI). A cross-sectional design was used to test internal consistency by calculating Cronbach's alpha.

Results: The DSMQ contains 16 items. There are eleven items (69%) which showed excellent CVI; two items (12.5%) showed good CVI and three items showed acceptable CVI. The average scale of CVI was 0.90. The internal consistency of the DSMQ was 0.73.

Conclusion: The Thai version of DSMQ showed excellent content validity; good internal consistency. The instruments can be used among Thai adults with DM in future research studies.
