Aval. psicol. [online]. 2020, vol.19, n.3, pp. 277-288. ISSN 1677-0471.  http://dx.doi.org/10.15689/ap.2020.1903.15631.06.

The aim of this study was to evaluate the temporal stability of the UWES instrument for the evaluation of work engagement. This construct is characterized by high vigor, dedication and absorption in the work. The sample was composed by 423 telemarketing workers and the test/retest methodology with an interval of 1 month was used. Descriptive and reliability analyses were carried out. The instrument presented adequate psychometric qualities (Cronbach´s Alpha >0.8; CFI >0.95; RMSEA <0.07) and showed good results regarding the Invariance Measurement between longitudinal samples (configural, metric and scalar), in agreement with data from the instrument's manual. Regarding the temporal stability there was an increase in Cronbach's Alpha values and Pearson's correlations were significant and positive. The results showed adequate psychometric quality with temporal stability, however, the need of future studies is emphasized, especially considering that the application was made using only one professional category, from one organization and region.

Palabras clave : work engagement; UWES; temporal invariance; temporal stability; psychometry.
