“…In this study, we first identified the best-fitting factor structure of the latest BESS SF by testing competing models and tested measurement invariance across race/ ethnicity, gender, and school using the best-fitting factor structure. Considering previous empirical support on the previous BASC-2 BESS SF for using a bifactor structure compared with other competing models (Dowdy et al, 2011;Naser et al, 2018b), we hypothesized that the bifactor model would provide the best fit compared with a non-hierarchical four-factor model and a second-order hierarchical model (Hypothesis 1). Next, as studies on the previous BESS SF (Harrell-Williams et al, 2015;Kim & Kamphaus, 2018) supported full and partial invariance across race/ethnicity and gender, respectively, we also expected the latest BESS SF to be invariant across White, Black, and Latinx students and across boys and girls (Hypotheses 2 and 3).…”
