摘要目的:探究内在动机和主动性行为在资质过剩感对手术室器官移植护士信息素养影响机制中的多重中介作用。方法:采用便利抽样法，于2023年11月选取我国12所医院的308名手术室器官移植护士作为调查对象。采用一般资料调查表、临床护理人员信息素养自评量表、资质过剩感量表、内在动机量表、主动性行为量表进行调查，构建链式中介模型。结果:本研究共回收问卷308份，有效问卷294份，有效回收率为95.45%。294名手术室器官移植护士的信息素养、资质过剩感、内在动机和主动性行为总分分别为（133.95±19.07）、（23.71±7.82）、（76.47±13.38）、（38.01±6.31）分。手术室器官移植护士资质过剩感对信息素养的间接效应存在，总的间接效应值为-0.348；内在动机的特定间接效应为总间接效应的40.80%，主动性行为的特定间接效应为总间接效应的31.03%，内在动机和主动性行为的链式中介效应为总间接效应的28.16%。结论:内在动机和主动性行为在资质过剩感对手术室器官移植护士信息素养影响机制中的多重中介作用成立。管理者可以通过降低手术室器官移植护士的资质过剩感，激发其内在动机和主动性行为，提升其信息素养水平。

abstractsObjective:To explore the multiple mediating roles of intrinsic motivation and proactive behavior in the influence mechanism of perceived overqualification on the information literacy of Operating Room nurses engaged in organ transplantation.Methods:On November 2023, 308 Operating Room nurses engaged in organ transplantation from 12 hospitals in China were selected for the survey using convenience sampling method. General information questionnaire, Information Literacy Self-Rating Scale for Clinical Nurses, the 9-item Scale of Perceived Over Qualification, Intrinsic Motivation Scale, and Proactive Behavior Scale were used to investigate and to construct the chain mediating model.Results:A total of 308 questionnaires were collected and 294 questionnaires were valid, with a valid recovery rate of 95.45%. The total scores of information literacy, perceived overqualification, intrinsic motivation and proactive behavior of 294 Operating Room nurses engaged in organ transplantation were (133.95±19.07), (23.71±7.82), (76.47±13.38) and (38.01±6.31) respectively. The indirect effect of perceived overqualification of Operating Room nurses engaged in organ transplantation on information literacy existed, with a total indirect effect value of -0.348. The specific indirect effect of intrinsic motivation was 40.80% of the total indirect effect, the specific indirect effect of proactive behavior was 31.03% of the total indirect effect, and the chain mediating effect of intrinsic motivation and proactive behavior was 28.16% of the total indirect effect.Conclusions:Multiple mediating roles of intrinsic motivation and proactive behavior in the influence mechanisms of perceived overqualification on the information literacy of Operating Room nurses involved in organ transplantation are established. Managers can improve the information literacy of Operating Room nurses engaged in organ transplantation by reducing their perceived overqualification and stimulating intrinsic motivation and proactive behavior.
