Practice what we theorize: reciprocity, timing, and heterogeneity in parenting adolescents research

Theories describe parenting processes in adolescence as reciprocal, timing-sensitive, and heterogeneous; however, these meta-theoretical principles are often not carried through into research designs. Despite earlier calls to bridge such theory – method gaps, they continue to pervade contemporary studies. Building on these earlier efforts, I explain why several gaps persist and highlight recent studies that align more closely with these theoretical principles. Their findings show that within-family associations between parenting and adolescent functioning are not solely parent-driven, unfold differently across timescales, and vary meaningfully across families. I end with methodological recommendations to further bridge these gaps, including modelling time-lagged effects, using micro-randomized trials, treating effects as timescale-sensitive, systematically examining heterogeneity, identifying generalizable patterns via bottom-up approaches, and adopting dynamic systems approaches. A closer match between theory and methods will ultimately yield more valid conclusions and evidence-based interventions.
