The Antecedents of Organ Donation Intention and Behavior: A meta-Analysis

Despite rising demand for organ donation, global rates remain low. This systematic review and meta-analysis identified the key factors influencing organ donation intentions and behaviors. We established a theoretical framework outlining the key determinants of organ donation intent and behavior. The analysis included 85 studies (N = 310,476), our results identified 48 antecedents and compared their differences based on (1) demographics, (2) rational behavior theory and planned behavior theory and their extensions, (3) emotional expectations, (4) prosocial motivation, and (5) donation experience. Additionally, we conducted an exploratory analysis to determine the moderating effects of publication year, sample population, methodology (sample collection method), and cultural background (national development level) on the relationship between antecedents and organ donation behavior. Publication bias and literature quality were also evaluated to determine the robustness and scalability of the results. We present the first meta-analysis research evidence on organ donation intention and behavior, summarizing ample empirical knowledge about organ donation in the literature and following contemporary meta-analysis guidelines and best practices to produce transparent and replicable scientific discoveries. Our findings also contribute to health interventions, health emergency and provide policy and practical implications for future health research.
