OBJECTIVE
The Theory of Planned Behavior (TPB) was used to compile a questionnaire to determine the relationship between knowledge, attitude, subjective norm, perceived behavioral control and the intention of university students to perform cardiopulmonary resuscitation (CPR) for strangers, and the factors influencing them.
METHODS
We recruited 575 university students who completed an online questionnaire within 30 min to assess knowledge, attitude, subjective norm, and perceived behavioral control related to bystander CPR. Factor analysis was used to evaluate the reliability of the extended questionnaire. Multivariate analysis, correlation analysis, and path analysis were used to determine the differences of intra-group and inter-group.
RESULTS
The Cronbach's α of knowledge, attitude, subjective norm, perceived behavioral control and intention were 0.770, 0.797, 0.909, 0.619 and 0.899 respectively, indicating that the extended scale reliability of the TPB was adequate. χ2/df = 3.463, GFI = 0.977, CFI = 0.968, IFI = 0.969, RMSEA = 0.066, indicating that the extended scale of the TPB had a good fit. Path analysis showed that the influencing factors of intention were "Families of medical workers", "Experience in administering CPR first aid training", "Gender", "Ability to master CPR skills", "Knowledge", "Subjective norm" and "Attitude", with effect values of 0.019, 0.063, 0.069, 0.122, 0.187, 0.361 and 0.386, respectively. All the factors together accounted for 57.00 % of the variation in intention.
CONCLUSIONS
Knowledge, attitude and subjective norm regarding to bystander CPR among university students are the determinants of intention, while perceived behavioral control does not play a major role. This study has implications for future CPR training. In order to improve the CPR implementation rate of university students, we should strengthen the relevant knowledge about CPR, maintain positive attitude and refine the related criteria of CPR implementation.
目的
运用计划行为理论（TPB）编制问卷，以确定大学生对陌生人实施心肺复苏（CPR）的知识、态度、主观规范、感知行为控制与意图之间的关系及其影响因素。
方法
招募575名大学生，他们在30分钟内完成一份在线问卷，以评估与旁观者心肺复苏相关的知识、态度、主观规范和感知行为控制。采用因子分析评估扩展问卷的信度。运用多变量分析、相关分析和路径分析来确定组内和组间差异。
结果
知识、态度、主观规范、感知行为控制和意图的Cronbach's α系数分别为0.770、0.797、0.909、0.619和0.899，表明TPB扩展量表的信度良好。χ2/df = 3.463，GFI = 0.977，CFI = 0.968，IFI = 0.969，RMSEA = 0.066，表明TPB扩展量表拟合良好。路径分析显示，意图的影响因素为“医务人员家属”“接受过心肺复苏急救培训的经历”“性别”“掌握心肺复苏技能的能力”“知识”“主观规范”和“态度”，效应值分别为0.019、0.063、0.069、0.122、0.187、0.361和0.386。所有这些因素共同解释了意图变异的57.00%。
结论
大学生对旁观者心肺复苏的知识、态度和主观规范是意图的决定因素，而感知行为控制不起主要作用。本研究对未来的心肺复苏培训具有启示意义。为提高大学生心肺复苏的实施率，应加强心肺复苏相关知识，保持积极态度并完善心肺复苏实施的相关标准。
