摘　　要：目的 解析献血自主感知影响内在动机的中介路径及满意度调节机制,探索献血内在动机促进因素以提升献血者持续参与效能。方法 本研究基于自我决定理论,选取1 293名具有献血经历的浙江省民营企业员工作为研究对象。通过无偿献血问卷收集人口学特征、献血内在动机及影响因素数据,并运用Spearman相关分析和PROCESS宏程序,分析各变量之间的关系及其作用机制。结果 在以自主感知、生活平衡感知、满意度为自变量的多元线性回归分析中,因变量献血内在动机60%的变异可由自变量共同解释(调整R~2=0.60)。在有调节的中介模型检验中,生活平衡感知中介了自主感知对献血内在动机的作用,献血满意度正向调节直接路径(β=0.06,P<0.01),而负向调节中介路径后半段(β=-0.04,P<0.01),揭示了满意度的双重调节效应。结论 自主感知与献血满意度协同驱动献血内在动机,综合考虑直接路径效应和中介路径间接效应的献血满意度确定策略,可为解决高初次献血率与低保留率的矛盾提供参考思路。Objective To analyze the mediating pathways of autonomy perception on the intrinsic motivation for blood donation and the moderating mechanism of satisfaction,and to explore the factors that enhance the intrinsic motivation of blood donation in order to promote sustained donor engagement and effectiveness.Methods This study,grounded in Self-Determination Theory(SDT),recruited 1293 employees from private enterprises in Zhejiang Province with prior blood do-nation experience as the research subjects.Data on demographic characteristics,intrinsic motivation for blood donation,and influencing factors were collected through a voluntary blood donation questionnaire.Spearman correlation analysis and the PROCESS macro were employed to examine the relationships among variables and their underlying mechanisms.Results In the multiple linear regression analysis with autonomy perception,life balance perception,and satisfaction as independent variables,60%of the variance in intrinsic motivation for blood donation was explained by these predictors(adjusted R2=0.60).In the moderated mediation model test,life balance perception mediated the effect of autonomy perception on intrin-sic motivation for blood donation.Furthermore,blood donation satisfaction positively moderated the direct path(β=0.06,P<0.01)while negatively moderating the second half of the mediation path(β=-0.04,P<0.01),revealing a dual mod-erating effect of satisfaction.Conclusion Autonomy perception and blood donation satisfaction jointly drive intrinsic moti-vation for blood donation.Strategies for optimizing blood donation satisfaction,which take into account both the direct path effect and the indirect mediation effect,can offer valuable insights for addressing the discrepancy between high first-time do-nation rates and low donor retention rates.
