基于自我决定理论的电话招募沟通策略对保留无偿献血者的效果及影响因素分析
Effectiveness and influencing factors analyses of telephone recruitment communication strategies based on self-determination theory in retaining unpaid blood donors
摘要
Abstract
Objective To explore the effectiveness of telephone recruitment communication strategies based on Self-Determination Theory(SDT)in retaining unpaid blood donors and to analyze the influencing factors for their re-donation.Methods A total of 13,965 unpaid blood donors were selected as study subjects and,after stratification by gender,age,and most recent blood donation volume,were randomly divided into a study group(n=7,061)or a control group(n=6,904)using a random number generator.The study group received SDT-based telephone recruitment communication strategies,while the control group received traditional telephone recruitment communication strategies.The primary outcome was the re-donation rate,which was evaluated using both intention-to-treat(ITT)and per-protocol(PP)analyses to evaluate the effectiveness of the SDT-based telephone recruitment communication strategies in retaining unpaid blood donors.Univariate analysis and multivariate logistic regression model were used to identify independent influencing factors for re-donation.Results ITT analysis results showed that the re-donation rate in the study group was higher than that in the control group(P<0.05);PP analysis results indicated that among donors who successfully answered the phone,those who received SDT-based telephone recruitment communication strategies had a re-donation rate 4 percentage points higher than those who received traditional telephone recruitment communication strategies(P<0.05).Univariate analysis results revealed statistically significant differences in re-donation rates among donors who received various telephone recruitment communication strategies and those with different call outcomes,gender,age,and most recent whole blood donation volume(all P<0.05).Multivariate logistic regression analysis results showed that telephone recruitment communication strategies,call outcomes,age,and most recent whole blood donation volume were independent influencing factors for unpaid blood donors're-donation(all P<0.05).Conclusions The application of SDT-based telephone recruitment communication strategies can increase the re-donation rate among blood donors,and telephone recruitment communication strategies,call outcomes,age,and most recent whole blood donation volume are independent influencing factors for their re-donation.关键词
