Summary Intense conflicts are prevalent in families receiving child welfare services. Research in the field of family interventions usually focusses on dyadic conflicts within the limits of the nuclear family unit, ignoring the larger social context of families. Therefore, this study analyses effects on interpersonal conflicts in personal networks of parents during a family intervention. The theoretical framework is based on the family systems theory, which highlights the role of mutual trust for conflict resolution. This research applied ego-centric network analysis in combination with a longitudinal design. The sample consists of 46 parents who were enrolled in a home-based family intervention in Switzerland. Findings The results show that development of mutual trust between practitioners and the network members of parents is associated with significant decrease in conflict density and conflict reciprocity. Hence, network members experience fewer interactions that are associated with conflict as well as less intense conflicts in the medium term. However, no effects were found on the centrality of parents in interpersonal conflicts. Applications The results of this study suggest that practitioners in family interventions must establish mutual trust with not only parents but also other individuals to promote a less stressful family environment. This emphasizes the importance of a network perspective on interpersonal conflicts in child welfare interventions.
