Study On Reliability And Validity Of DESIGN - R In Chinese Healing State Of Healing

Objectives: To translate and revise pressure ulcer classification and severity scale DESIGN-R, to get the Chinese version of pressure ulcer classification and severity scale DESIGN-R, and to evaluate the reliability and validity of the Chinese version of DESIGN-R scale among Chinese patients with pressure ulcers.Methods: After we got the original author’s agreement and authority, we translated and translated back the scale and made cultural adaptation.Brislin’s translation model was applied to translated the Japanese version of pressure ulcer classification and severity scale DESIGN-R. The scale was translated into Chinese according to translation program, and then we got the Chinese version of DESIGN-R scale. Sampling was used to choose pressure ulcer patients. We collected patients’ information and pressure ulcers’ photos.5 raters using the scale assessed the photos of pressure ulcers. We evaluated the test-retest reliability, internal consistency reliability, inter-rater reliability,content validity, and construct validity of the Chinese version of pressure ulcer classification and severity scale DESIGN-R.Results: The index of content validity of the scale was 0.93. The coefficient of correlation among entries( except depth) was 0.46~0.80, all correlations were significant(P<0.01). The function of 2 factors of factor analysis accounted for 64.53% of the total variance. The basic dimensions of each corresponding entry were with higher factor loading. The internal consistency reliability of the scale was 0.82; the split-half reliability was 0.76.The intraclass correlation coefficient of the inter-reliability was at 0.79~0.99, and the ICC of test-retest reliability was 0.90. The Cronbach’s αcoefficient of the scale was 0.70~0.79 if items was deleted.Conclusions: The Chinese version of DESIGN-R scale has good reliability and validity and can be used to evaluate pressure ulcers of Chinese.
