Reliability and validity of the Turkish version of the ‘Resuscitation Self-Efficacy Scale’ for nurses: a methodological study

Background: Resuscitation management is a highly demanding clinical process requiring nurses to demonstrate competence and efficiency. Aim: This study aimed to evaluate the psychometric properties of the Turkish version of the Resuscitation Self-Efficacy Scale (RSES), which measures nurses’ self-efficacy in resuscitation management. Methods: This cross-sectional methodological study included 217 nurses actively working in clinical settings. Linguistic validity was ensured through forward–backward translation, and content validity was established via expert evaluation. Construct validity was assessed using confirmatory factor analysis after verifying sampling adequacy with Kaiser–Meyer–Olkin (KMO) and Bartlett’s tests. Reliability was evaluated using Cronbach’s alpha for internal consistency and the intraclass correlation coefficient (ICC) for test–retest reliability. Results: Model fit indices indicated acceptable fit. The KMO value was 0.934 and Bartlett’s test was significant (χ 2 = 2495.41, p < 0.001). Cronbach’s alpha for the total scale was 0.942, and ICC values showed high reliability. Strong positive correlations were found between the total RSES score and its sub-dimensions (Recognition r = 0.817; Debriefing and recording r = 0.880; Responding and rescuing r = 0.912; Reporting r = 0.842). Conclusion: The Turkish RSES is a valid and reliable tool for assessing nurses’ resuscitation self-efficacy and may support clinical practice and intervention development.
