“…Most research has thus far tested unidirectional paths independently (except Matos et al, 2018). These studies tested either the teacher-facilitating path or the student-facilitating path, through cross-sectional (Benlahcene et al, 2022; Bordbar, 2019, 2021; Jiang & Zhang, 2021), longitudinal (Michou et al, 2023; Patall et al, 2022; Reeve, 2013), experimental (Reeve et al, 2022), or intervention (Patall et al, 2019; Reeve et al, 2020) research strategies. Such an “either-or” approach precludes statistical tests of bidirectionality (i.e., reciprocal relations) between autonomy support and agentic engagement.…”
