Translation, adaptation and validation of instruments or scales for cross-cultural research is very time-consuming and requires careful planning and the adoption of rigorous methodological approaches to derive a reliable and valid measure of the concept of interest in the target population.

The 15-item three-factor ASAS-R is a short, reliable and valid instrument to measure self-care agency among individuals from the general population, but further psychometric evaluation is needed among individuals with chronic diseases, especially those with diabetes mellitus.

Costly complications of diabetes often arise from poor glycemic control. Appropriate diabetes self-care management may improve control. This study examined whether self-care management affects glycemic control and mediates relationships between self-efficacy and self-care agency with glycemic control. In a cross-sectional correlational design, data from a prior study of 141 insulin-requiring adults with type 1 or type 2 diabetes were examined using descriptive statistics, Pearson's correlation, and multiple hierarchical regression. Findings indicated that greater self-care agency and self-efficacy lead to greater self-care management, in turn leading to better glycemic control. Self-care management did not mediate between self-efficacy or self-care agency and glycemic control. Thus, beliefs or capabilities for self-care are insufficient to improve glycemic control; doing so requires self-care management.

The scales can be used by diabetes care providers to assess and follow-up individuals with diabetes who need intense case management. They also can be the measures of choice to conduct future research to test the effects of interventions among insulin-treated individuals with T2DM.
