From mothers to children and back: Bidirectional processes in the cross-generational transmission of anxiety from early childhood to early adolescence

Background: Maternal psychopathology and caregiving behavior are linked with child anxiety and these associations may be particularly salient when families face mass trauma together and members influence each other's symptomatology and resilience. Despite the well-known mother-to-child effects, less research addressed the longitudinal bidirectional effects of maternal and child's anxiety symptoms on each other. Methods: Mothers and children exposed to chronic war-related trauma from Sderot, Israel, and comparison group were followed at three time-points; Early childhood (T1:N = 232, M_Age = 2.76 years), late childhood (T3:N = 176, M_Age = 9.3 years), and early adolescence (T4:N = 110, M_Age = 11.66 years). At each time-point maternal and child's anxiety symptoms were evaluated via questionnaires and maternal sensitivity was coded from videotaped observations of parent–child interactions. Bidirectional associations were examined using traditional cross-lagged panel model (CLPM) and CLPM with random intercepts (RI-CLPM). Results: Trauma-exposed mothers and children exhibited more anxiety symptoms and lower maternal sensitivity. Cross-lagged panel models revealed cross-time bidirectional associations between maternal anxiety and child anxiety from early to late childhood. Child anxiety at each time-point predicted maternal anxiety and maternal sensitivity at the next stage; however, maternal sensitivity did not show longitudinal associations with child anxiety, highlighting children's role in shaping caregiving. Conclusions: Findings demonstrate bidirectional cross-generational influences of mother and child on each other's anxiety in contexts of trauma and pinpoint early childhood as a sensitive period for such mutual influences. Children's increased anxiety following trauma appears to be further exacerbated via its impact on increasing maternal anxiety and compromising sensitive caregiving, underscoring the potential benefits of parental and mother-child interventions for trauma-exposed populations.
