Mother-father and parent-grandmother coparenting conflict and caregiver involvement in adolescent parent families

Family systems theory recognizes the complex interconnected subsystems within families, yet little is known about how multigenerational coparenting affects coparenting and caregiving outcomes within adolescent parent families. The current study estimated auto-regressive cross-lag models to evaluate the interrelation between mother-father and parent-grandparent coparenting subsystems and caregiver involvement using reports of coparenting conflict and caregiver involvement from 280 adolescent parents (Mage = 17.02, SD = 1.42; 83.6% Latine; 69.6% women) at two time-points, collected nine-months apart. Results showed stability in coparenting conflict and caregiver involvement among mother-father and parent-grandparent dyads and one intergenerational cross-lag effect. Grandmother involvement at time 1 (T1) was negatively linked to parent-grandparent coparenting conflict at time 2 (T2). Gender differences also emerged, such that (1) father's report of mother involvement at T1 was positively associated with mother-father coparenting conflict at T2; (2) father's report of mother involvement at T1 was negatively associated with father's report of grandmother involvement at T2; and (3) father's report of parent-grandparent coparenting conflict at T1 was negatively associated with father's report of mother involvement at T2. Findings underscore connections between intergenerational coparenting subsystems and suggest gender differences in sensitivity, malleability, and the influence of the coparenting dyad on coparenting conflict and caregiver involvement. Further research on adolescent coparenting and caregiving dynamics across coparenting subsystems is needed to strengthen interventions aimed at serving young mothers and fathers.
