Besides the moderation analyses, the study provides further evidence for the association of prenatal stress and children’s subsequent psychopathological symptoms. It therefore emphasises the need for early supportive interventions aimed at mothers who report a high burden of prenatal stressors. The reduction of modifiable prenatal stressors (e.g. lack of social support, work stress, burden of internalising symptoms, substance consumption) would likely have long-lasting positive effects on children’s mental health and might be feasible within the scope of interventions targeting mothers’ well-being. Such interventions could include support groups for pregnant mothers or short-team (maybe even group- or internet-based) cognitive behavioural interventions.
