The objective of the present research was to determine the degree of validity and reliability of an instrument that measures the perception of the Quality of Work Life to provide elements on the strength of its psychometric properties. A quantitative methodology was used, with a non-experimental design, cross-sectional scope and descriptive type. The sample consisted of 202 workers from three organizations, located in the municipality of Navojoa, Sonora, Mexico, the type of sampling was a convenience fee. Construct validity and reliability tests were formulated for internal consistency. Validity results by varimax rotation indicate that the 15 dimensions of the instrument explain 65.9% of the variance of the instrument results, while the Cronbach's alpha coefficient for the global scale shows a value of 0.974, both results are considered adequate. It is concluded that the instrument has acceptable validity and reliability properties that allow it to continue with tests to strengthen such properties, as well as being valid and reliable to collect the perception of the quality of work life in workers.
