Linguistic and psychometric validation of the Thai version of Simplified Diabetes Knowledge Scale : A measure of knowledge of diabetes in a Thai population

Purpose
To develop a linguistically and psychometrically validated Thai version of the Simplified Diabetes Knowledge Scale (T-SDKS) for adults with Type 2 diabetes mellitus (T2DM).

Design
A cross-sectional study was carried out among people with T2DM.

Methods
Consecutive sampling was undertaken to recruit participants at the outpatient diabetes clinic of a hospital in Northern Thailand.

Results
A total of 502 patients with T2DM were recruited. The mean age of the participants was 60.2 years, and 60.5% were female. The T-SDKS attained a reliability coefficient of .79. The item-total correlation value was greater than 0.20 for each item, and the inter-item correlation ranged between 0.03 and 0.49. Respondents attained a mean percentage knowledge score of 42.39% ± 15.45 on T-SDKS.

Discussion/conclusions
The T-SDKS has demonstrated to be a brief and simple diabetes knowledge assessment tool to use in a busy clinical setting.

Implication for practice
The findings can be used to improve health education interventions.
