“…Outside the context of play, prosocial and aggressive behaviors have been linked to a range of adaptive outcomes within and across childhood. For example, prosocial behavior is correlated with a range of developmental outcomes, including fewer problem behaviors (Padilla‐Walker, Memmott‐Elison, & Coyne, 2018), lower peer victimization (Sugimura, Berry, Troop‐Gordon, & Rudolph, 2017), and higher academic achievement (Coulombe & Yates, 2018; Hall & DiPerna, 2017). Likewise, a plethora of evidence documents enduring associations between children’s aggressive behaviors and higher rates of peer delinquency and victimization (Fite & Vitulano, 2011; Frey & Strong, 2018), earlier initiation of substance use (Fite, Colder, Lochman, & Wells, 2008), poorer psychosocial adjustment (Kamper & Ostrov, 2013) and lower academic achievement (Savage, Ferguson, & Flores, 2017).…”
