Background and Objectives
Individual motivations for blood donation play a vital role in maintaining and enhancing voluntary participation in the healthcare system. Self-Determination Theory (SDT) provides robust conceptual framework for analyzing various levels of motivation, ranging from extrinsic to intrinsic. The objective of this study was to examine the motivation of voluntary whole blood donors across all blood centers of Iran based on SDT approach.
Materials and Methods
This cross-sectional study was conducted on 7,187 voluntary whole blood donors who attended the largest blood donation center in each province during October and November 2024. Data were collected using a psychometrically validated SDT-based questionnaire. Statistical analysis was performed using STATA version 17, employing a mixed-effects linear regression model. To account for the hierarchical structure of the data, predictive margins were calculated for each province and compared against the national average.
Results
The mixed-effects model results demonstrated that motivational levels significantly predict blood donation behavior across all provinces (p<0.001). The findings indicated a intrinsic motivation was high among donors in all 31 provinces. The predicted margins for intrinsic motivation varied from 4.70 in Kohgiluyeh and Boyer-Ahmad to 4.01 in Gilan blood center on a 5-point Likert scale. Approximately 84% of the blood ceuter (26 provinces) fell within the national confidence interval. Only 5 blood centers (approximately 16%) lay outside this range; two provinces showed lower values (4.01 and 4.24), while three provinces exhibited higher values (4.67, 4.68, and 4.70).
Conclusions
High intrinsic motivation—grounded in SDT principles—across all Iranian provinces indicates that blood donation is largely viewed as an inherently rewarding behavior. Leading provinces in this regard, such as Lorestan, Kohgiluyeh and Boyer-Ahmad, and West Azerbaijan, should examine their support policies and success factors to serve as models for other provinces. Conversely, provinces like Gilan and Tehran need to identify limiting factors and implement effective interventions to boost motivation levels. These regional disparities may stem from various factors—such as cultural and economic infrastructure and local management policies—warranting further in-depth investigation in future research.
