Development and Psychometric Properties of TQWL-42 to Measure the Quality of Work Life

ABSTRACT

Abstract The objective of this study was to construct and validate an instrument that evaluates the Quality of Work Life (QWL) globally, following the WHOQOL instruments and founded in QWL's classical theoretical models, directed to the contemporary society. The psychometric properties tested were content validity, face validity, internal consistency, criterion validity, concurrent validity and test-retest reliability in an application to 283 individuals. The final version of the instrument is constituted by 47 questions, being five to sample knowledge and 42 divided in five spheres that contemplate QWL's dimensions. For the results calculation a SPSS syntax and a tool in Microsoft Excel that perform the automated calculation after the data tabulation were developed. The psychometric properties tested were satisfactory. We conclude that the goal of validating a global instrument for evaluation of QWL from the contemporary society culture with satisfactory psychometrical characteristics was reached.
