The objective of this study was to examine the psychometric properties of the Spanish version of the "Survey Work-Home Interaction-Nijmegen" (SWING), developed by S. Geurts, in a sample of Chilean public workers. Its psychometric properties were studied with a sample of 1,135 workers from public institutions in Chile. The results of the confirmatory factor analysis indicate a four-factor model. The original structure of the scale was retained, containing 22 items distributed across four subscales: negative work-family interaction, negative family-work interaction, positive work-family interaction, and positive family-work interaction. The reliability analysis of the scale indicated that this Spanish version has good internal consistency, with values ranging from 0.82 to 0.94. Significant correlations were found between the SWING and measures related to each dimension of the scale. It is concluded that this version possesses appropriate psychometric properties, and guidelines are suggested for the use of the Spanish version of this questionnaire in future research.
