“…Parent–adolescent conflict is an ubiquitous feature of early adolescence that can play an important developmental role in renegotiating family relationships to support increasing autonomy needs (Branje, 2018). However, frequent and intense conflicts are consistently shown to predict poorer adolescent adjustment across both internalizing and externalizing dimensions (Huey, Hiatt, Laursen, Burk, & Rubin, 2017; Weymouth, Buehler, Zhou, & Henson, 2016). In order to better understand this multiplicity of outcomes, the current study compares two complementary explanations for why increases in parent–adolescent conflict in early adolescence may be associated with adolescent adjustment problems: through the spillover of adolescent hostility and by undermining adolescents’ secure attachment behavior.…”
