Abstract:
Objective To develop the risk assessment scale for adult patients with incontinence-associated dermatitis ( IAD) and to test the validity and reliability. To provide a tool to assess the risk of IAD in clinical practice. Methods The items of the scale were confirmed using the structured method from multi-dimensions. Delphi expert consultation was performed to select the items. The initial scale was formed after confirming the weight of items by comprehensive scored method. 408 patients were tested. The scale was analyzed by means of Cronbach′s α coefficient, rater consistency, test-retest reliability, construct validity, content validity, sensitivity, specificity and the area under ROC curve. Results The scale included seven items and three dimensions, which were tissue tolerance, perineal environment and self-care ability. The Cronbach′s αcoefficient was 0.53. The rater consistency reliability was 0.904. Factor analysis extracted 3 common factors that the characteristic roots value was >1. The accumulative variance contribution explained 59.13% of the variance for the total scale. The load values of seven items were obtained by varimax orthogonal rotation. Three common factors were attributed according to the load value. And the factor load value on each item mentioned was higher than 0.4. The content validity of items was all greater than 0.78. The content validity of scale ( S-CVI/UA) was 0.857, and S-CVI/AVE was 0.975. Area under ROC curve was 0.84 ( P<0. 01, 95% CI:0.77-0.91) . When the boundary of the diagnostic cut-off level of high-risk people was set at 46.5 points, the sensitivity was 88.9% and the specificity was 76.9%.Conclusions The construction of the scale which has a good reliability and validity is scientific. The instrument can be used to assess the risk of the occurrence of IAD in adult patients.
