Abstract

PURPOSE: This research was carried out to evaluate the validity and reliability of the Korean version of the Summary of Diabetes Self-Care Activities Questionnaire (SDSCA) for Korean older adults with type 2 diabetes.
METHODS
Translation and back-translation were performed to develop the Korean version of the SDSCA. Then the Korean version SDSCA was applied to a sample of 112 older adults who had participated in diabetes self management education in Seoul. The internal consistency and the test-retest reliability were examined to test the reliability. Factor analysis was used to examine the construct validity.
RESULTS
The internal consistency measured with Cronbach's alpha was .77 and the total test-retest reliability was .68 with items ranging from .21 to 1.00. As the result of the factor analysis, six factors -foot care, diet, exercise, blood sugar test, medication, and smoking- were revealed as the original instrument subcategories. These six factors explained 81.17% of total variance.
CONCLUSION
The reliability and validity of the Korean version SDSCA Questionnaire was supported for use in older patients with type 2 diabetes in Korea.
