Introduction: The prevalence rates of bullying vary significantly across countries and continents. Specifically, UNESCO estimates that the prevalence rates vary from 22.8% (CentralAmerica) to 48.2% (Sub-Saharan Africa).

We used latent growth curve analysis to extend research on associations between early puberty and adverse peer relations by examining the role of pubertal timing in the developmental trajectories of peer victimization and offending from early- to mid-adolescence. We made use of three-wave longitudinal data collected annually from a cohort of…

Aggressiveness was not predictive of later crime for girls until they reached age 13. For both genders, relation between aggressiveness and crime was largely…

The authors investigated the predictive and incremental validity of the Early Assessment Risk List for boys (EARL-20B; Augimeri, Koegl, Webster, & Levene, 2001), a structured clinical checklist designed for the professional judgment of risk for aggressive and disruptive behaviors and risk/needs factor-based management of this risk. Seventy-six…
