Interventions to retain existing donors are essential to increase the blood supply. Blood donor self-identity is proposed to motivate sustained donation behaviour. However, interventions to develop self-identity in the absence of donating blood are scarce. We propose that experiencing psychological ownership of a blood collection agency (BCA) may provide a potential avenue for fostering donor self-identity and subsequent sustained donation behaviour.
Two hundred and fifty-five donor participants were recruited through Prolific Academic (n = 175) and an Australian online blood donor community group (n = 80), with an additional 252 non-donors recruited through Prolific Academic. Participants completed an online survey assessing donation behaviour, perceived psychological ownership of a BCA, self-identity and intentions to donate blood, amongst other constructs.
Consistent with our theoretical argument, psychological ownership was positively associated with self-identity, which, in turn, was positively associated with intentions to donate blood. Donation behaviour was positively associated with psychological ownership. Examination of psychological ownership by donation experience showed the expected relationship with committed donors having the strongest psychological ownership and non-donors having the weakest psychological ownership over a BCA.
We provide initial support for the inclusion of psychological ownership within a model of sustained blood donation behaviour.
保留现有献血者的干预措施对于增加血液供应至关重要。献血者的自我认同被认为可以激励持续的献血行为。然而，在没有献血的情况下发展自我认同的干预措施却很少。我们提出，体验对采血机构（BCA）的心理所有权可能为培养献血者自我认同和随后的持续献血行为提供一个潜在途径。
通过 Prolific Academic（n=175）和澳大利亚在线献血者社区小组（n=80）招募了 255 名献血者参与者，通过 Prolific Academic 招募了另外 252 名非献血者。参与者完成了一项在线调查，评估了献血行为、对 BCA 的感知心理所有权、自我认同以及献血意愿等其他结构。
与我们的理论论点一致，心理所有权与自我认同呈正相关，而自我认同又与献血意愿呈正相关。献血行为与心理所有权呈正相关。通过对献血经验的心理所有权进行考察，结果显示，与承诺献血者相比，坚定的献血者对 BCA 的心理所有权最强，而非献血者的心理所有权最弱。
我们为将心理所有权纳入持续献血行为模型提供了初步支持。
