The need for kidney transplantation among Asian Americans is increasing owing to hypertension, diabetes mellitus, and the shortage of available organs. This need is likely to increase as the relatively young Asian population ages. However, knowledge about organ donation and transplantation in this population has been little investigated. The objectives of this study was to develop an Organ Donation and Transplantation Knowledge Survey for use in Asian Americans and to examine its psychometric properties. Internal consistency (Cronbach alpha) and factor analyses were used to determine the reliability and validity of the survey in 121 Asian American adolescents residing on the Big Island of Hawaii. Our results indicate that the survey had adequate reliability and was psychometrically valid for evaluating knowledge about organ donation and transplantation. More studies are needed to validate the usefulness and psychometric properties of the Organ Donation and Transplantation Knowledge Survey in other groups.
