Objectives Families offer promising targets for mental health interventions. Existing evidence investigates parent-child dyads or partners; we use an innovative approach to look at triads of parents and their children. This gives us more detail on mental health dimensions and individuals central to mental health transmission in families. Design Both cross-sectional and longitudinal network models Setting We identified triads of children (under age 16), mothers and fathers from the UK Household Longitudinal Study, between 2009 and 2022. Participants and methods Cross-sectional networks captured independent associations between family members’ mental health (n=8795 families). Longitudinal networks examined directional temporal associations among family members’ emotional symptoms (n=3757 families). Primary outcome measures Children’s and parents’ mental health dimensions were assessed using the Strengths and Difficulties Questionnaire and the General Health Questionnaire, respectively. Results Mothers’ mental health, particularly emotional symptoms, was linked to children’s mental health, while fathers’ symptoms showed no independent association. In the longitudinal network, maternal feelings of being overwhelmed were associated with children’s future worry, affecting symptoms of nervousness and unhappiness, which then fed back into worsening maternal emotional symptoms. Conclusions Investigating family mental health using network models highlights mothers’ central role. The longitudinal relationship between maternal feelings of being overwhelmed and children’s anxiety, and the subsequent feedback into maternal anxiety, indicates a promising target for intervention.
