Abstract

Organ donation saves lives and improves the quality of life. There is a shortage of organ donors worldwide. Behavior theories, such as the theory of planned behavior (TPB), help identify the antecedents of organ donation behavior and design effective interventions. The TPB suggests that intention is driven by constructs: attitude, subjective norm, perceived behavioral control (PBC), and intention. TPB can help improve organ donation behavior. This study aimed to analyze TPB-based interventions on Organ donation. Relevant studies were identified searching electronic databases, i.e., PubMed, Scopus, Science Direct, and Google Scholar from January 1, 2000 to February 30, 2020. None MeSH terms in title or abstract were searched, including: 'theory of planned behavior∗' and 'Tissue donation' or 'Tissue procurement' or 'Organ procurement system' or 'Organ procurement' or 'Organ donation.' Two authors independently reviewed the full texts and extracted all critical data from the included studies. Seventeen studies were assessed as having a reasonable methodology design. Studies show that TPB-based interventions can improve organ donation. Among TPB's constructs, PBC is the moderator and the determinant of organ donation behavior which its determination is different in different cultures. Attitude, subjective norms, moral norms, and anticipated regret should be considered in related interventions plus PBC. Increasing knowledge can facilitate organ donation behavior. Removing related cultural issues, removing fear due to misunderstanding of Brain death, improving trust, and improving moral values have effects on the behavior of organ donating. © 2021 Saudi Center for Organ Transplantation.All right reserved.
