The high motivation of rescuers for cardiopulmonary resuscitation (CPR) can result in high-quality CPR. However, there is no instrument to measure the CPR motivation. The purpose of this study was to design the Cardiopulmonary Resuscitation Motivation Scale (CPRMS) and evaluate its psychometric properties.
Directed qualitative content analysis and other related instruments were used for the production of items pool, and then the psychometric properties of the CPRMS were evaluated using face, content and construct validities, and internal consistency, and stability for reliability.
The CPRMS was consisted of 43 items. The Scale-Content Validity Index was reported as 0.97. Exploratory factor analysis led to eight factors, which in total accounted for 48.58% of observed variance. Confirmatory factor analysis also showed the average fit of the explored model. The values of alpha, omega and intraclass correlation coefficients were reported as 0.92, 0.76-0.86, and 0.90 respectively.
CPRMS is a valid and reliable instrument for the measurement of CPR motivation in eight dimensions of facilitators of resuscitation, feeling of achievement, high chances of success, low chances of success, recognition and appreciation, accountability, perceived importance, and beliefs. CPRMS can differentiate between rescuers with high and low motivation.
救援人员对心肺复苏（CPR）的高度积极性可带来高质量的心肺复苏。然而，目前尚无测量心肺复苏积极性的工具。本研究旨在设计心肺复苏动机量表（CPRMS）并评估其心理测量特性。
采用定向定性内容分析法及其他相关工具生成条目池，然后通过表面效度、内容效度、结构效度、内部一致性以及可靠性的稳定性来评估CPRMS的心理测量特性。
CPRMS由43个条目组成。量表内容效度指数报告为0.97。探索性因素分析得出八个因素，共解释了48.58%的观测方差。验证性因素分析也显示了所探索模型的平均拟合度。α系数、ω系数和组内相关系数的值分别报告为0.92、0.76 - 0.86和0.90。
CPRMS是一种有效且可靠的工具，可从复苏促进因素、成就感、高成功几率、低成功几率、认可与赞赏、责任感、感知重要性和信念这八个维度测量心肺复苏动机。CPRMS能够区分积极性高和低的救援人员。
