Determinants of Medical Students for Intention to Organ Donation: Application of Theory of Planned Behavior

Organ donation and transplantation save thousands of lives in the world. The aim of this study was identifying determinants of organ donation intention based on the Theory of Planned Behavior (TPB) among Iranian Medical Students. This cross-sectional study was performed during 2017 in Shahid Beheshti University of Medical Sciences. A sample of 438 students of Shahid Beheshti University of Medical Sciences was selected using multi-stage sampling method including stratified and random sampling. Data were collected by using a reliable and valid TPB-based questionnaire. All the participants filled the questionnaires and the data were extracted according to the previously described method. Data were analyzed by using the Statistical Package for the Social Sciences version 16.0 software. Descriptive statistic and Spearman correlation and Logistic regression were used for analyzing the data. Mean age of the participants was 20.92 +/- 1.98 years. There was a significant linear positive correlation between behavioral intention and attitude, subjective norms, and perceived behavior control. Logistic regression analysis for assessing relation of TPB variables with behavioral intention showed that perceived behavioral control was more correlate with students' intention for getting organ donation card (odds ratio: 1.049, confidence interval: 1.062, P <0.000) perceived behavioral control, explain student's willingness to register as an organ donor. We must provide facilities so that students could register for organ donation easily.
