Background/Objectives: This cross-sectional study was performed with 105 undergraduate nursing students in three universities in Korea. Methods/Statistical analysis: The majority of participants were trained in emergency treatments such as basic life support (BLS) or other types of CPR education. Participants had received BLS training within 1 year, and their demographic variables, self-efficacy, and BLS satisfaction were examined. Collected data were analyzed using descriptive statistics, Pearson’s correlations and hierarchical regression with SPSS 21.0. Findings: Results showed a statistically significant correlation between BLS education satisfaction and CPR self-efficacy, which is the largest contributor to CPR-related self-efficacy with r =.784 (p < .01). Study variables were entered into a two-block hierarchical regression model . Students’ factors were grouped in Block 1, which represented 0.7% of variance of CPR-related self-efficacy. Amount of CPR education and BLS learning satisfaction and CPR education factors were grouped in Block 2. Education factors in Block 2 increased in variance to 60.6% with F = 40.556 (p < .001). Examining the beta scores of individual factors, BLS learning satisfaction was the greatest contributor to the variance (B = .559, s = .780, and p < .001). Improvements/Applications: Since the relationship between self-efficacy and learning satisfaction has been proven, education with multidimensional strategy to improve student’s learning satisfaction will bring improved results in emergency.
