Measuring the expectations of kidney donors: initial psychometric properties of the Living Donation Expectancies Questionnaire.

摘要

We report on the initial development and validation of the Living Donation Expectancies Questionnaire (LDEQ), designed to measure the expectations of living kidney donor candidates. Potential living donors (n=443) at two transplant centers were administered the LDEQ and other questionnaires, and their medical records were reviewed. Factor analysis provides support for six LDEQ scales: Interpersonal Benefit, Personal Growth, Spiritual Growth, Quid Pro Quo, Health Consequences, and Miscellaneous Consequences. All but one scale showed good internal consistency. Expected benefits of donation were associated with higher optimism and lower mental health; expected consequences of donation were associated with lower optimism and lower physical and mental health. More potential donors with relative or absolute contraindications had high Interpersonal Benefit (P<0.0001), Personal Growth (P<0.01), Quid Pro Quo (P<0.0001), and Health Consequences (P<0.0001) expectations. The LDEQ has promise in evaluating donor candidates' expectations.
