ABSTRACT=Purpose: This study aims to investigate the impact of physical activity and self-control on college students' mobile phone addiction through cross-lagged longitudinal surveys, addressing the limitations of previous cross-sectional studies.Patients and methods: A total of 414 college students were tracked for three times during a period of 12 months by using Physical Activity Rating Scale-3 (PARS-3), he Mobile Phone Addiction Tendency Scale (MPATS) and Brief Self-Control Scale (BSCS). AMOS25.0 software was used to construct the cross-lagged relationship model, and the maximum likelihood 2 approach was employed investigate the model fitting. The asynchronous correlation between variables was investigated from the time series through the cross-lagged path coefficient.The fitting indexes of the cross-lagged model showed: x 2 / df = 5.098, GFI = 0.977, NFI = 0.969, IFI = 0.975, CFI = 0.974; RMSEA = 0.100, SRMR = 0.030. The calculation conducted by combining the path coefficient of the model shows that PA and SC are the antecedent variables of MPA, and PA is the antecedent variable of SC. In addition, SC serves as a mediator in the path of PA affecting MPA.(1) physical activity can positively affect subsequent self-control; (2) physical activity can negatively influence subsequent mobile phone addiction; (3) Self-control can negatively affect subsequent mobile phone addiction; (4) physical activity can indirectly influence subsequent mobile phone addiction through self-control.
