Conclusion
Parental experiences of barriers and facilitators towards participating in the parental support intervention highlighted that the commitment of the school staff and a well-functioning interaction between the school and the parents is crucial for participation. Moreover, involvement of both parents and other key people around the child is important. Adaptation of the intervention on the right level, follow-ups, and continuous delivery of relevant health information needs attention. Furthermore, it is important to have in mind that the intervention may have unexpected positive impacts regarding integration of migrant families on the one hand. On the other hand, circumstances related to variations in social and cultural conditions can be a barrier to the execution of the programme. The findings of this study can contribute to improve parental involvement and to better planning, execution, and implementation of family support interventions.
