Trajectories of psychosocial functioning across maltreatment levels: A group-based modeling approach to resilience.

Child maltreatment increases the risk of emotional and behavioral problems, yet many children demonstrate resilience, functioning better than expected given their level of maltreatment exposure. Although resilience is a dynamic process shaped by children's social support, including friendships, how different patterns of resilience and friendship support unfold together across development remains unclear. To better understand this process, we examined how patterns of emotional resilience, behavioral resilience, and friendship support co-develop across childhood and adolescence. We used group-based multi-trajectory modeling with data from the Avon Longitudinal Study of Parents and Children (N = 6, 518, 51% female) to identify distinct patterns of emotional and behavioral resilience (doing better-than-expected given their level of maltreatment exposure) and friendship support, across five timepoints from ages 6 to 17 years. We identified five trajectory groups. Nearly half the sample maintained high emotional and behavioral resilience and friendship support across development. While resilience trajectories varied, friendship support was generally high across groups. Most children followed trajectories of high resilience and perceived friendship support. Even among children with lower emotional and/or behavioral resilience trajectories, friendship support remained high, an encouraging finding. Future research should examine how children's other relationships (e.g., with parents and siblings) unfold alongside resilience.
