The Utrecht Work Engagement Scale for Students (UWES-9S): Factorial Validity, Reliability, and Measurement Invariance in a Chilean Sample of Undergraduate University Students.

This brief report examines the within-network construct validity of the UWES-9S in a convenience sample of 1502 Chilean students (52% were female) ranging between 18 and 25 years old. The results of confirmatory factor analysis supported a solution with three related factors that fit significantly better than a one-factor solution. The three subscales (i.e., vigor, dedication, and absorption) and the overall UWES-9S showed satisfactory internal consistency. The results of multiple-group confirmatory factor analysis supported gender invariance. Overall, the UWES-9S was found to be a reliable and valid scale to assess academic engagement in Chilean undergraduate university students.
