“…The current study addressed this issue and used a longitudinal cross-lagged design to seek the reciprocal relationships between social relationships (teacher-student and peer relationships) and grit in the EFL learning context. Unlike the existing studies (e.g., Hejazi and Sadoughi, 2022 ; Shen and Guo, 2022 ; Yuan, 2022 ) that only focused on one specific interpersonal relationship: the teacher-student relationship or peer relationships within the learning environment, we highlighted them synchronously because both types of interpersonal relationships exist concurrently during language learning. In addition, given that gender plays an essential effect in EFL learning ( Sunderland, 1992 ; Ma et al, 2017 ; Bataineh et al, 2018 ; Namaziandost and Çakmak, 2020 ; Van Ha et al, 2021 ), we also investigated whether the relations between social relationships (teacher-student relationship and peer relationships) and grit within the EFL learning context differ by gender.…”
