Abstract: | Research on the role of parent–adolescent relationships in psychosocial adjustment needs a conceptual approach that specifies the processes by which development is nested in the relationship. I forward a new approach and emphasize the need to consider the unique elements that individuals bring to the dyadic system. I also emphasize the need to examine processes at multiple time scales. I highlight the complexity of dyadic system dynamics: Biological predispositions set the foundation for the parent–adolescent relationship and the emotion dynamics that emerge during interactions. As the system gets entrained through repeated interactions over longer time scales, real‐time dynamics coalesce into psychosocial adjustment, which in turn constrains real‐time dynamics. I review the evidence for each of these processes and discuss the implications. |
