Abstract:

This study investigated the longitudinal relationship between perceived discrimination and aggression among rural middle school students, as well as the mediating role of loneliness. A three-wave tracking survey was conducted at six-month intervals with 804 students from five rural schools in Sichuan Province, using the perceived discrimination scale, aggression scale, and loneliness scale. Cross-lagged panel analysis demonstrated stable positive correlations among perceived discrimination, aggression, and loneliness across all three measurements, along with a bidirectional predictive relationship between perceived discrimination and aggression. Moreover, loneliness was identified as a significant longitudinal mediator in this reciprocal relationship. These findings clarify the longitudinal mechanisms linking perceived discrimination with aggression, providing a theoretical basis for the prevention of aggressive behaviors in junior high school students.
