The Quality of Work Life Scale: Validity Evidence from Brazil and Portugal

This study aims to assess the validity eviden ce of the Quality of Work Life Scale (QWLS) by examining the internal structure of the measure (i.e., dimensionality, reliability, and measurement invariance) and its relations with other variables such as burnout and work engagement. The measure was tested using a total sample of 1163 workers, 566 workers from Portugal, and 597 from Brazil. The data had a good fit to the QWLS second-order model and good reliability estimates for the two countries. Full-uniqueness measurement invariance was achieved for data for Portugal and Brazil and for gender too. The measure also demonstrated good nomolog ical validity evidence by successfully predicting burnout and work engagement.
