Abstract
BACKGROUND: Timely bystander cardiopulmonary resuscitation is the key to improving the survival rate of out-of-hospital cardiac arrest. Civil servants are potential bystander CPR providers. This study aimed to explore civil servants' willingness to implement CPR in Chongqing, identify the influencing factors and mechanisms affecting civil servants' willingness to perform CPR, and then seek countermeasures to improve civil servants' willingness to implement CPR. METHODS: We introduced the theory of perceived risk into the theory of planned behavior, developed a 7-point Likert scale based on the extended theory of planned behavior, and conducted a questionnaire survey on civil servants in Chongqing, China. Descriptive statistical analysis and one-way ANOVA were employed to explore respondents' willingness and differences. Structural equation modeling was used to analyze the relationship between attitude, subjective norm, perceived behavioral control and perceived risk and respondents' willingness to implement CPR. RESULTS: A total of 1235 valid questionnaires were included for analysis. 50.1 % of respondents were willing to implement CPR. Male, over 40 years old, living with the elderly, having previous experience performing CPR on another person, and having higher CPR knowledge scores were associated with a more positive willingness to perform CPR. Attitude, subjective norm and perceived behavioral control had significant positive effects on willingness, and the standardized regression coefficients were 0.164, 0.326 and 0.313, respectively. The perceived risk has a significant negative effect on willingness, and the standardized regression coefficient was -0.109. The four latent variables accounted for 44.2 % of the variance in the willingness of civil servants to implement CPR. CONCLUSIONS: The willingness of civil servants in Chongqing to implement CPR needs to be improved, and the countermeasures to enhance the subjective norm and perceived behavioral control of civil servants should be emphasized, such as developing a social support network for rescuing conduct, establishing regular training mechanisms and improving the practical applicability and popularization of the Chinese-style "Good Samaritan Law" etc., to improve the willingness of civil servants in Chongqing to implement CPR.
