The purpose of this study was to explore the role of functional motivation and blood donor stage in the future intention to donate blood. Three sites in China provided 252 blood donors who filled out a questionnaire including the volunteer function inventory, their future intention to donate blood, number of blood donations and demographic information. Based on a functional motivation approach, we investigated the motivations that influence unpaid blood donors\u2019 future intention through qualitative interview methods. The results showed that blood donor stage moderated the relationship between values motivation and future intention to donate blood. More specifically, the predictive effect of values motivation on future intention decreased gradually from new donors to regular donors. Our study found that the effect of various motivations on blood donors\u2019 intention was conditional; this effect changed with the development of blood donor behavioral stages. The results are significant in practice for establishing effective intervene strategies in maintaining blood donors.<\/jats:p>","DOI":"10.3390\/ijerph18179115","type":"journal-article","created":{"date-parts":[[2021,8,29]],"date-time":"2021-08-29T21:45:16Z","timestamp":1630273516000},"page":"9115","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["The Effect of Functional Motivation on Future Intention to Donate Blood: Moderating Role of the Blood Donor\u2019s Stage"],"prefix":"10.3390","volume":"18","author":[{"given":"Lifan","family":"Zhang","sequence":"first","affiliation":[{"name":"Faculty of Psychology, Beijing Normal University, Beijing 100875, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0342-5990","authenticated-orcid":false,"given":"Meilin","family":"Yao","sequence":"additional","affiliation":[{"name":"Faculty of Psychology, Beijing Normal University, Beijing 100875, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongrui","family":"Liu","sequence":"additional","affiliation":[{"name":"Faculty of Psychology, Beijing Normal University, Beijing 100875, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuang","family":"Zheng","sequence":"additional","affiliation":[{"name":"Faculty of Psychology, Beijing Normal University, Beijing 100875, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,29]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2021, August 13).
