The Spillover Effects of Classmates' Police Intrusion on Adolescents' School-Based Defiant Behaviors: The Mediating Role of Institutional Trust

Peers' negative police encounters may have collateral consequences and shape adolescents' relationship with authority figures, including those in the school context. Due to the expansion of law enforcement in schools (e.g., school resource officers) and nearby neighborhoods, schools include spaces where adolescents witness or learn about their peers' intrusive encounters (e.g., stop-and-frisks) with the police. When peers experience intrusive police encounters, adolescents may feel like their freedoms are infringed upon by law enforcement and subsequently view institutions, including schools, with distrust and cynicism. In turn, adolescents will likely engage in more defiant behaviors to reassert their freedoms and express their cynicism toward institutions. To test these hypotheses, the present study leveraged a large sample of adolescents (N = 2,061) enrolled in classrooms (N = 157) and examined whether classmates' police intrusion predicted adolescents' engagement in school-based defiant behaviors over time. Results suggest that classmates' intrusive police experiences in the fall term predicted higher levels of adolescents' engagement in defiant behaviors at the end of the school year, regardless of adolescents' own history of direct police intrusive encounters. Adolescents' institutional trust partially mediated the longitudinal association between classmates' intrusive police encounters and adolescents' defiant behaviors. Whereas past studies have largely focused on individual experiences of police encounters, the present study uses a developmental lens to understand how the effects of law enforcement-perpetuated intrusion on adolescent development may operate through peer interactions. Implications for legal system policies and practices are discussed.
