This study examined the attitudes and commitment to posthumous organ donation among a group of nurses (N=314) in a teaching hospital in Hong Kong. Attitude was operationally defined by a self-report measure of favorable or unfavorable feelings and beliefs about organ donation, whereas commitment was defined by having signed a donor card. Consistent with findings reported in the West, nurses who exhibited favorable attitudes towards organ donation were of greater proportion than those who had signed a donor card. Younger and unmarried nurses were more likely to commit to posthumous organ donation. More than half (55%) of the nurses were undecided about commitment to organ donation, but most of them were likely to sign a donor card. Principal component analysis confirmed the conceptual structure of the Organ Donation Attitude Scale developed by Parisi and Katz (Health Psychol. 5 (1986) 565-580). Reliability of the factor scores (Humanitarian and moral conviction, Fears of bodily mutilation, and Fears of medical neglect) was satisfactory (Cronbach alpha ranged from 0.80 to 0.86). Fears of bodily mutilation were most significantly related to unwillingness to commit to organ donation. Implications of the findings for nursing education are discussed and suggestions for future research made.
