Development and psychometric evidence of the Academic Engagement Scale (USAES) in Mexican college students.

School engagement is considered an effective college dropout antidote; therefore, understanding the construct, its underpinnings, and its effects remains critical for scholars. Although several scholars have offered multiple scales to measure engagement, their use has been hindered by significant limitations. This study sought to develop a scale to measure academic engagement by unifying and improving existing work and theories that resulted in a three-dimensional measurement model (behavioral, emotional, and cognitive). The items included were validated by a group of experts who ensured that the wording of the items captured the uniqueness of the college experience. A sample of 992 Mexican college students was used to test the fit of a second-order three-dimensional factor model of school engagement. The sample was randomly split in two for model cross-validation. Confirmatory factor analyses confirmed that student engagement is a three-dimensional construct, with evidence that supports the hypothesized second-order engagement factor structure (behavioral, emotional, and cognitive). The stability of these models was confirmed by using an independent sample. Measurement invariance by gender was found in this model. Then, differences in latent factor means were analyzed. Finally, the scale showed discriminant and concurrent validity. These results indicate that the scale is theoretically and psychometrically grounded for measuring college students' school engagement.
