Background: Little is known about heterogeneity in developmental trajectories of alcohol and marijuana use among at-risk youth. Objective: This study aims to examine how child maltreatment and father structural factors at different stages in the life course are associated with different patterns of alcohol and marijuana use trajectories. Methods: A sample of youth (N = 903) were drawn from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN). Latent class growth analysis was employed to assess heterogeneity in patterns of adolescent alcohol and marijuana use. In addition, binary logistic regression analysis was performed to examine child maltreatment and father structural factors across different developmental stages as predictors of membership in the identified alcohol and marijuana use trajectory classes. Results: For both alcohol and marijuana use, two distinct latent classes were identified: stable no/low alcohol use (74%) vs. increasing alcohol use (26%); stable no/low marijuana use (85%) vs. increasing marijuana use (15%). Emotional abuse during early childhood and physical abuse during adolescence predicted membership in the increasing alcohol use and the increasing marijuana use classes. The presence of father in the home during early childhood was associated with lower likelihood of being in the increasing alcohol use class. Conclusions: Our findings highlight the importance of understanding the etiology of adolescent substance use through a developmental lens. Screening of exposure to child maltreatment across different developmental stages and interventions promoting father engagement during early childhood might help mitigate the risk of adolescent alcohol and marijuana use.

The primary aim of the study was to investigate the development of psychobehavioral symptoms (internalizing, externalizing, and posttraumatic stress [PTS]) of child welfare–involved adolescents over a 3-year period and to identify predictors of the trajectories. Using three waves of data from the National Survey of Child and Adolescent Well-Being (NSCAW-II), latent growth curve modeling was conducted on a sample of 350 adolescents who were between 11 and 13 years of age at baseline. Findings indicated that adolescents’ internalizing symptoms decreased over time, whereas externalizing symptoms remained stable over time. PTS symptoms decreased over time in girls, but not boys. Physical abuse predicted higher levels of externalizing behaviors and sexual abuse predicted a slower decrease in PTS symptoms. Greater child prosocial skills and higher quality of caregiver–child relationship were associated with lower initial levels of externalizing symptoms. In addition, a higher quality caregiver–child relationship and greater satisfaction with peer relationships were associated with lower initial levels of internalizing and PTS symptoms. Findings suggest that intervention strategies should consider gender, maltreatment type, and interpersonal and social skills to effectively prevent the development of psychobehavioral symptoms among child welfare–involved youth.

This study examined transitions in resilience profiles and the role of caregiver risk and protective factors in resilience transition probabilities over 18 months among children involved with the child welfare system, using latent profile analysis and latent transition analysis. The sample included 486 children (48% female, baseline Mage = 3.49). There were three resilience profiles at Time 1 (19.9% low emotional behavioral, 26.1% low cognitive, 54.0% multidomain) and two profiles at Time 2 (18.9% low emotional behavioral, 81.1% multidomain). Caregiver mental health problems were negatively associated with membership in the multidomain resilience group at Time 1. Higher levels of cognitive stimulation were associated with initial and continued membership in the multidomain resilience group. Implications for resilient child development are discussed.
