This study fills a gap in what is known about parent–adolescent resistance dynamics.\n\n\nMethods\nA state space grid approach informed by dynamic systems and family conflict theories was conducted on two videorecorded conversations in a sample of 26 Canadian parent–adolescent dyads. Flexibility, attractor, and intergrid distance analyses assessed intradyadic variability in how parents and adolescents resisted one another moment to moment.\n\n\nResults\nAttractor analysis revealed that the most probable state during resistance sequences shifted: Before high school it was the Parent Justifying–Adolescent Justifying cell, after it was the Parent Minimizing–Adolescent Rejecting cell. t‐test results of intergrid distance scores showed a significant difference in the positioning of resistance sequences after high school.\n\n\nConclusion\nResults offer evidence that dyadic resistance differs before and after significant family transitions like the move to high school.\n\n\nImplications\nFuture research on dyadic resistance microprocesses could examine whether the proposed conceptual categories could be applied to dyads across multiple areas of difference to scrutinize its utility for a range of cultural and caregiver relationships.\n\n"]
