Content Validity of the Left Ventricular Assist Device Bathing Assessment

Abstract

Many institutions recommend modified bathing techniques for individuals with left ventricular assist devices (LVADs) due to infection risk. Although these techniques may be challenging for patients, there currently is no assessment to evaluate these skills and whether intervention programs have been successful. This article describes the development and content validation of the LVAD Bathing Assessment. The content validity index (CVI) process was used to determine the relevance of assessment items. Modified Kappa indices were calculated to account for the possibility of chance agreement among raters. Eight content validity experts rated each assessment item and provided feedback. The overall assessment and 44 of 47 individual items had excellent content validity (scale-level CVI [S-CVI] = 0.97; item-level CVI [I-CVI] > 0.78). Minor revisions were made based on feedback. Creation of an LVAD bathing assessment may improve care by identifying safety risks that may cause infection. Further studies for construct validation and reliability testing are needed.
