The Validity and Reliability of a Korean Version of the Diabetes Self-Care Barriers Assessment Scale for Older Adults with Type 2 Diabetes

Abstract

Purpose: The purpose of this study was to test the validity and reliability of the Diabetes Self-Care Barriers Assessment Scaler for Older Adults (DSCB-OA) in Korean older adults with type 2 diabetes. Method: To develop Korean version DSCB-OA used translation and backtranslation method. Then, Korean version DSCB-OA was analyzed using data of 278 older adults with type 2 diabetes. Cronbach's alpha coefficient, item to total correlation and test-retest reliability was used for the reliability test, and factor analysis was used for the construct validity. Results: Cronabach's alpha of the DSCB-OA was .77, and item to total correlation coefficient ranged from -.13 to .56 . The results of factor analysis showed DSCB-OA consisted of four factors(diet, exercise, blood sugar test, treatment) which explained 62.8% of total variance. Conclusion: The Diabetes Self-Care Barriers Assessment Scaler for Older Adults (DSCB-OA) was confirmed helpful tool for Korean older adults with type 2 diabetes.

The Influence of Health Literacy and Diabetes Knowledge on Diabetes Self-care Activities in Korean Low-income Elders with Diabetes

“…The total score ranged from 0 to 112 (where higher scores=high levels of self-care activities). The reliability of the tool from the study by Chang & Song [20] was Cronbach's ⍺=.77 while that of this study was Cronbach's ⍺=.74.…”

“…Diabetes self-care activities were measured with the 25-questionnaire Summary of Diabetes Self-Care Activities Questionnaire (SDSCA) developed by Toobert & Glasgow [18], modified by Toobert et al [19], and translated into Korean by Chang & Song [20]. When excluding questions that could not be scored, a total of 17 questions assessed the domains of diet, exercise, medication, blood glucose test, and foot management.…”

“…One question was asking 'the number of days to administer insulin injection' which the subject for insulin administration only could answer. Therefore, we calculated an average score of this question with the question asking 'the number of days to administer diabetes medication' with an approval by the author [20]. The total score ranged from 0 to 112 (where higher scores=high levels of self-care activities).…”

Psychometric evaluation of the Korean version of the Diabetes Self‐efficacy Scale among South Korean older adults with type 2 diabetes

“…). In a study on the K‐SDSCA, the reliability measured with Cronbach's alpha was 0·77 and the construct validity was evaluated by factor analysis (Chang & Song ). The Cronbach's alpha of the study was 0·78.…”

“…The translation processes were guided by Bracken and Barona (1991)'s method that included translation, blind back-translation, committee review and pilot testing for the cross-cultural adaptation of an instrument. This method has been widely used in studies on cross-cultural adaptation of an instrument for Korean (Chang & Song 2009), Chinese (Li et al 2008) and Spanish (Unruh & Lowe 2010) populations. The DSES was translated into Korean by one experienced qualified bilingual translator who had a doctorate in nursing.…”
