Signing an organ donation letter: The prediction of behavior from behavioral intentions

Research output: Contribution to journalArticlepeer-review


The signing of an organ donation letter was examined among 149 unmarried university students. The letter was developed for the purpose of conveying one's wishes regarding posthumous donation to one's next of kin. Predictors of letter signing were examined that explain hypothesized inconsistencies between the behavioral intention to sign and actual letter-signing behavior. Respondents were offered the opportunity to sign and send the donation letter to their parents. As predicted, reported willingness to sign the letter was only moderately related to actual behavior. Decision confidence, organ donation knowledge, and perceived decision importance positively influenced signing, independent of willingness. Unfavorability toward defending one's donation decision to one's parents inhibited signing, even among those expressing a high initial willingness to sign.
