“…Notably, we do not find a direct link between early puberty and externalizing, in keeping with some previous studies (Negriff & Trickett, 2010) but not others (Caspi et al, 1993). Reasons for this may include the way externalizing was measured, given that previous research suggests that early puberty predicted only non-violent forms of delinquency (Harden & Mendle, 2012); and that research with clinical samples such as ours (Negriff & Trickett, 2010) and racially diverse samples such as ours (Deardorff et al, 2013; Obeidallah, Brennan, Brooks-Gunn, & Earls, 2004) with similarly aged girls does not find a direct effect of early puberty on externalizing symptoms. Finally, we did not find evidence that the presence of older boyfriends alone predicts either internalizing or externalizing symptoms, corroborating previous studies (Javdani et al, 2014) suggesting that the influence of older boyfriends does not persist past early adolescence (Haydon & Halpern, 2010).…”
