Validation and Psychometric Properties of the Spanish Version of the Second Victim Experience and Support Tool Questionnaire

Abstract

Objectives: This study aimed to assess the validity and psychometric properties of the Spanish version of the Second Victim Experience and Support Tool (SVEST-E) questionnaire.

Methods: This was a cross-sectional study aimed at midwives and obstetricians in Spain. An online survey was conducted consisting of 2 parts: the first part collected different variables, and the second part collected the SVEST-E. The temporal stability of the instrument was evaluated using the test-retest method. For the construct validity and reliability, an exploratory factor analysis and a confirmatory factor analysis were performed using FACTOR program v.10 with a polychoric correlation matrix.

Results: A total of 689 professionals participated in the study (323 obstetrician physicians/366 midwives). The mean (SD) score on the SVEST-E for the total sample was 3.09 (0.50). The parallel analysis of the exploratory factor analysis suggested a 5-factor solution, with a total explained variability of 61.8%. The goodness-of-fit indices of the model were the following: root mean square error of approximation = 0.038 (95% confidence interval [CI], 0.031-0.042) and comparative fit index = 0.989 (95% CI, 0.988-0.992). The factor model obtained was confirmed by confirmatory factor analysis, obtaining the values of root mean square error of approximation = 0.038 (95% CI, 0.026-0.053) and comparative fit index = 0.989 (95% CI, 0.969-1.000). The intraclass correlation coefficient was 0.97 (95% CI, 0.94-0.99).

Conclusions: The SVEST-E instrument maintains the same items as the original questionnaire but introduces changes in the organization of its dimensions. The Spanish version maintains adequate construct validity, reliability, and temporal stability, so it is a valid tool to evaluate the second victim experience in Spanish health professionals.
