Propiedades psicométricas de la versión Española del cuestionario de interacción trabajo-familia (SWING)

Abstract

Psychometric properties of the Spanish version of the Survey Work-Home Interaction Nijmegen (SWING). The aim of this work was to analyze the psychometric properties of the Spanish version of the «Survey Work-Home Interaction Nijmegen» (SWING) developed by S. Geurts and colleagues to evaluate the relationships between work and family. Its psychometric properties were analyzed with data from a sample of 283 emergency professionals. Results of confirmatory factor analyses indicated that the four-factor model, in which both kinds of positive and negative interactions were not correlated, provided the best fit to the data (GFI= 0.98, AGFI= 0.98, NFI= 0.97, RMR= 0.03). Thus, this version maintains the original structure of 22 items distributed in four factors: negative work-home interaction, negative home-work interaction, positive work-home interaction and positive home-work interaction. Reliability analysis showed good internal consistency for this Spanish version with Cronbach alpha coefficients for the factors ranging from .77 to .89. Significant correlations were found between the SWING and various scales related to work, family, and well-being, which provided evidence of convergent validity. Thus, this version shows adequate psychometric properties. Guidelines are also provided for the use of the Spanish version of the SWING in future investigations.
