Validity and Reliability of the Persian Version of the Organ Donation Attitude Survey in the Iranian Community

Background: In the world, more than 10% of transplant waiting list patients die each year due to a shortage of donated organs. And the shortage of organs for donation has become a global phenomenon, which is getting worse by the day. Also, the current supply of transplant members is much less than they need. This growing gap between the number of organ donors and recipients is a serious challenge for governments. Therefore, the present study was conducted to evaluate the validity and reliability of the Persian version of the Organ Donation Attitude Survey (ODAS) in Iranian community.

Materials and Methods: Participants in this study were 328 Iranian community people, who were selected by convenience sampling method, and completed the organ donation attitude survey, then the factor structure of the questionnaire and its reliability were examined.

Results: The results of exploratory factor analysis supported the validity of questionnaire constructs and showed two factors. The factor load values of the items ranged from 0.591 to 0.857. The reliability of the instrument by internal consistency method (Cronbach's alpha) for the whole instrument was equal to 0.82.

Conclusion: The results showed that the organ donation attitude survey has good validity and reliability in the Iranian community and this questionnaire will be a suitable tool for measuring the attitude to organ donate of Iranian. And given the important role of individual beliefs and the role of the family in the donation process, governments must make effort in order to prepare a suitable context in order to promote the tendency of people to donate organs.
