“…Research by Haynie (2003) showed that early puberty is particularly strongly related to “party delinquency,” that is, such victimless offending as drinking, smoking, truancy, and disorderly conduct, and that delinquent peer associations and dating behavior are the principal mechanisms accounting for this effect. In general, there is persuasive evidence of peer mediation processes in studies of pubertal development and various types of adverse outcomes, including depression, school failure, and substance abuse (Cavanagh, Riegle-Crumb, & Crosnoe, 2007; Halpern et al, 2007; Marklein, Negriff, & Dorn, 2009; Tanner-Smith, 2012).…”
