Having prior experience of receiving blood was the strongest predictor for being a blood donor, followed by being registered as an organ donor, after controlling for all other factors in the logistic regression model.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The findings are consistent with self-determination theory, which hypothesises that people are more likely to abide with blood donation behaviours that are internally rather than externally motivated.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1136\/bmjopen-2019-031865","type":"journal-article","created":{"date-parts":[[2020,1,20]],"date-time":"2020-01-20T07:15:31Z","timestamp":1579504531000},"page":"e031865","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":36,"title":["Knowledge level and motivation of Hong Kong young adults towards blood donation: a cross-sectional survey"],"prefix":"10.1136","volume":"10","author":[{"given":"Lorna Kwai Ping","family":"Suen","sequence":"first","affiliation":[{"name":"School of Nursing, Faculty of Health and Social Sciences, The Hong Kong Polytechnic University, Hung Hom, Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0825-6564","authenticated-orcid":false,"given":"Judy Yuen-man","family":"Siu","sequence":"additional","affiliation":[{"name":"Department of Applied Social Sciences, Faculty of Health and Social Sciences, The Hong Kong Polytechnic University, Hung Hom, Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yik Mun","family":"Lee","sequence":"additional","affiliation":[{"name":"Hong Kong Red Cross Blood Transfusion Service, Hospital Authority, King's Park, Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Engle Angela","family":"Chan","sequence":"additional","affiliation":[{"name":"School of Nursing, Faculty of Health and Social Sciences, The Hong Kong Polytechnic University, Hung Hom, Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2020,1,19]]},"reference":[{"key":"2025120618010484000_10.1.e031865.1","first-page":"20","volume-title":"Gender distribution of blood donors and blood recipients in Rasheed Shekoni teaching hospital Dutse, Jigawa state, Nigeria","volume":"2","author":"Alla","year":"2019"},{"key":"2025120618010484000_10.1.e031865.2","doi-asserted-by":"crossref","first-page":"454","DOI":"10.1016\/j.transci.2017.05.004","article-title":"Survey on knowledge, attitude and practice about blood donation among continuing medical education (CME) students in Sichuan Province, China","volume":"56","author":"Gao","year":"2017","journal-title":"Transfus Apher Sci"},{"key":"2025120618010484000_10.1.e031865.3","unstructured":"Wayne F .
