Aggression Development in Adolescence

What is Aggression Development in Adolescence?
Aggression development in adolescence examines longitudinal trajectories of aggressive behaviors from childhood predictors to adult outcomes using developmental taxonomy and genetic-environmental models.
Researchers identify distinct trajectories of externalizing behaviors like aggression and opposition across adolescence (Bongers et al., 2004, 568 citations). Studies link early physical aggression curves to persistent antisocial patterns (Alink et al., 2006, 411 citations). Over 10 papers from 1999-2020 analyze predictors including family dynamics and bullying victimization.
Why It Matters
Trajectories of adolescent aggression predict adult conduct disorder and delinquency, enabling targeted interventions (Lahey, Moffitt, Caspi, 2003, 1007 citations). Bullying involvement increases depression and suicidality risks, informing school policies (Kaltiala-Heino et al., 1999, 781 citations). Long-term bullying effects persist into adulthood, raising societal costs for mental health services (Wolke & Lereya, 2015, 736 citations). School-wide positive behavior supports reduce aggression trajectories (Horner, Sugai, Anderson, 2010, 564 citations).
Key Research Challenges
Heterogeneous Trajectory Identification
Distinguishing stable high-aggression from declining trajectories requires large longitudinal cohorts (Bongers et al., 2004). Group-based modeling faces sample bias issues in adolescence samples. Validation across diverse populations remains limited (Alink et al., 2006).
Genetic-Environmental Interactions
Disentangling heritability from family dynamics in aggression persistence challenges causal models (Lahey, Moffitt, Caspi, 2003). Twin studies needed but scarce in bullying-aggression links. Measurement of gene-environment interplay lacks standardization.
Longitudinal Outcome Prediction
Predicting adult antisocial outcomes from adolescent aggression faces attrition in follow-ups (Wolke & Lereya, 2015). Bullying's role in trajectory shifts requires multi-wave designs. Intervention effects on trajectories show mixed evidence (Horner, Sugai, Anderson, 2010).
