Introduction: It has been suggested that psychological factors such as fear of failure may contribute to low rates of cardiopulmonary resuscitation (CPR). In CPR education, quantitative assessment of knowledge and skills is important, but assessment of psychological aspects may also be important in improving bystander CPR rates. Objective: To develop a scale to assess bystander self-efficacy for CPR (CPR-SES) and to test its reliability and validity. Methods: A preliminary scale (12 items, 5-point Likert scale) assessing self-efficacy for CPR was developed. A questionnaire was administered to 237 students at University A in Japan and items were selected using exploratory factor analysis. Subsequently, a questionnaire was administered to 195 students from University A and 372 students from University B in Japan. Model fit was assessed using multigroup analysis with structural equation modeling. To test validity, correlation analyses were conducted between the CPR-SES and the CPR Behavioral Intentions Scale (BICPRS), the General Self-Efficacy Scale (GSES), and the State-Trait Anxiety Scale (STAI). Results: Eight items (one-factor structure) were selected for the CPR-SES with sufficient internal consistency (Cronbach's α = 0.87) and model fit (Comparative Fit Index [CFI] = 0.948, Standardized Root Mean Square Residual [SRMR] = 0.04). This scale showed significant correlations with the other three scales, confirming adequate convergent validity. Conclusion: The developed CPR-SES showed adequate reliability and validity. Further research is needed to generalize these results across all age groups and on a national scale.
