In a published paper(Tušl, M., Bauer, G. F., Kujanpää, M., Toyama, H., Shimazu, A., & de Bloom, J. (2024). Needs-based job crafting: Validation of a new scale based on psychological needs.Journal of Occupational Health Psychology, 29(2), 57–71. https://doi.org/10.1037/ocp0000372), I find the authors computing overall mean score for work engagement based on the Utrecht Work Engagement Scale . They wrote that:
Work engagement was assessed with the nine-item version of the Utrecht Work Engagement Scale (Schaufeli et al., 2006). The scale measures three underlying dimensions of work engagement: vigor (e.g., “At work, I feel like I am bursting with energy”), dedication (e.g., “I am enthusiastic about my job”), and absorption (e.g., “I am immersed in my work”). The items were scored on a 7-point scale ranging from 0 = never to 6 = always. We calculated an overall mean score for work engagement. Cronbach’s α of the scale was 0.97.
