    Psychometric evaluation of the Brief-COPE Inventory and exploration of factors associated with perceived stress among Peruvian nurses
    (Multidisciplinary Digital Publishing Institute (MDPI), 2024-09-01)
    This study aimed to analyze the psychometric properties of the Brief-COPE Inventory and to determine its concurrent validity by examining its association with perceived stress among Peruvian nurses. Methods: A psychometric study was conducted with 434 Peruvian nurses to evaluate the psychometric properties of the Brief-COPE Inventory through confirmatory factor analysis. Three stepwise variable selection regression models were implemented. Results: The three-factor model of the Brief-COPE Inventory demonstrated adequate fit indices (root mean square error of approximation = 0.052, standardized root mean square residual = 0.068, and both the comparative fit index and the Tucker–Lewis index = 0.95). Additionally, the factors were significantly correlated (p < 0.001), and the reliability was adequate (ω = 0.90). Nurses reported a medium level of perceived stress, with associated factors including having received stress management training, fear of COVID-19, and problem-focused coping strategies (p < 0.05). Conclusion: This study confirms that the Brief-COPE Inventory is a valid tool for measuring coping strategies among Peruvian nurses due to its good model fit, excellent reliability, and concurrent validity with perceived stress. However, further research is needed to assess its validity in the specific areas of performance perceived by nursing professionals.

    Psychometric Validation of the Connor–Davidson Resilience Scale 10 in Peruvian Nurses and Its Association with Stress and Empathy
    (Multidisciplinary Digital Publishing Institute (MDPI), 2026-04-01)
    Background: This study aims to psychometrically validate the abbreviated version of the Connor–Davidson Resilience Scale (CD-RISC-10) in Peruvian nurses, evaluating its convergent validity through its association with perceived stress and empathy. Methods: A cross-sectional psychometric study was conducted in 374 Peruvian nurses to evaluate the psychometric properties of CD-RISC-10 through confirmatory factor analysis (CFA). Furthermore, concurrent validity was assessed through correlational analysis using Spearman's rho coefficient to evaluate the relationships among resilience, perceived stress, and empathy. Results: The CFA supported the predominantly one-dimensional model showing an adequate fit when the residual covariance between Items 4 and 7 was specified after correlating the residuals of Items 4 and 7 (CFI = 0.978, TLI = 0.971, RMSEA = 0.080, and SRMR = 0.044). Ordinal Cronbach's alpha of 0.89 and McDonald's omega of 0.81 were obtained. Concurrent validity showed significant correlations with perceived stress (rho = −0.53, p &lt; 0.001) and empathy (rho = 0.31, p &lt; 0.001). Conclusions: The CD-RISC-10 has adequate psychometric properties in Peruvian nurses. Future studies are needed to evaluate its factorial invariance between clinical specialties and establish normative thresholds.
