Despite growing attention to resilience following childhood maltreatment, it remains unclear how the development of resilience unfolds over time among child welfare-involved adolescents. Further, little is known about the immediate and enduring effects of two important attachments in children’s lives, namely caregiver–child relationship and deviant peer affiliation, on resilience development over time. This study sought to examine the ways in which caregiver–child relationships and deviant peer affiliation shape developmental trajectories of resilience among child welfare-involved youth. Data were drawn from the National Survey of Child and Adolescent Well-Being. Latent growth curve modeling was conducted on a sample of 711 adolescents. The results revealed that adolescents’ resilience increased across a 36-month period since initial contact with Child Protective Services. Better caregiver–child relationships were associated with a higher initial level of resilience among adolescents, whereas higher deviant peer affiliation was associated with a lower initial level of resilience. Significant lagged effects were also found; caregiver–child relationship quality and deviant peer affiliation at baseline were associated with resilience at 18 months after. The findings suggest that interventions that aim to promote positive caregiver–child relationships and prevent deviant peer relationships may help foster resilience among adolescents who have experienced child maltreatment.

We evaluated whether the association between deviant peer affiliation and onset of substance use is conditional upon sex and sympathetic nervous system (SNS) reactivity as measured by pre-ejection period (PEP). Community-sampled adolescents (N = 251; M = 15.78 years; 53% female; 66% White, 34% Black) participated in three waves. PEP reactivity was collected during a mirror star-tracer stress task. Alcohol, marijuana, tobacco, or any substance use, as well as binge drinking and sexual activity involving substance use were outcomes predicted by affiliation with deviant peers and two- and three-way interactions with sex and PEP reactivity. Probability of substance use increased over time, but this was amplified for adolescents with greater deviant peer affiliation in conjunction with blunted PEP reactivity. The same pattern of results was also found for prediction of binge drinking and sexual activity involving substance use. Findings are discussed in the context of biosocial models of adolescent substance use and health risk behaviors.

Non-shared parenting and deviant peer affiliation are linked to differences in externalizing behaviors between twins. However, few studies have examined these two non-shared environments simultaneously. The present study examined the transactional roles of differential parenting (i.e., warmth and hostility) and deviant peer affiliation on monozygotic (MZ) twin differences in externalizing behaviors using a two-wave longitudinal study of twins and their parents. The sample consisted of 520 pairs of MZ twins (46.5% males, 53.5% females), with a mean age of 13.86 years (SD = 2.10) at the T1 assessment, residing in Beijing, China. The association between non-shared hostility in parenting and adolescent externalizing behaviors was mainly explained by a child-driven effect whereby the twin with a higher level of externalizing behaviors than his or her co-twin was more likely to receive more hostility from the parents. Similarly, the relationship between deviant peer affiliation and adolescent externalizing behaviors supported the selection effect whereby the twin with a higher level of externalizing behaviors than his or her co-twin was more likely to affiliate with deviant peers. The theoretical and practical implications of these findings are discussed.
