[Validity and Reliability of the Korean Version of the Occupational Coping Self-Efficacy Scale for Nurses].

Purpose: This study aimed to evaluate the validity and reliability of the Korean version of the occupational coping self-efficacy for nurses (K-OCSE-N) scale.

Methods: The English version of the OCSE-N scale was translated into Korean using a translation and back-translation process. Data were gathered from 213 nurses employed in a general hospital in South Korea. The content validity was assessed using the content validity index. The construct validity was verified through exploratory and confirmatory factor analyses. Criterion validity was assessed using Pearson's correlation coefficients with the job stress coping and general self-efficacy scales. Reliability was examined using item-total score correlation and Cronbach's α coefficient for internal consistency.

Results: The exploratory factor analysis identified two factors that explained 61.8% of the cumulative variance: occupational burden and relational difficulty. In confirmatory factor analysis, the model exhibited adequate fit (χ²/df = 2.07, GFI = .95, SRMR = .04, RMSEA = .07, CFI = .97, and TLI = .95), with both convergent and discriminant validity deemed acceptable. The criterion validity presented a positive correlation of the K-OCSE-N with both job stress coping (r = .72, p < .001) and general self-efficacy (r = .72, p < .001). The internal consistency of the scale using Cronbach's α for the total items was .89.

Conclusion: The K-OCSE-N scale is a valid and reliable tool for measuring nurses' occupational coping self-efficacy. This study suggests that various intervention studies can use the scale to assess and strengthen nurses' occupational coping self-efficacy in nursing practice.
