A Mentalization Based Prevention Program to Foster Well-Being and Mental Health in Pre-Adolescent Children and Their Families

The FLOW project involves the implementation and rigorous evaluation of an evidence-based, multi-level mentalization prevention program targeting social and psychological determinants of well-being in four European countries (Germany, Lithuania, Spain, and Switzerland). Prevention programs will be tailored to the needs of 8-10 year old children in elementary schools and their parents. All children will participate in a project day focused on mental health. Parents will either attend one of two parent trainings of varying lengths or receive a parenting guidebook. A total of 5,000 children, along with their teachers and parents, are included in the survey. To measure long-term effects, surveys are conducted over the course of a whole year. The project examines the following hypotheses: Primary hypotheses: A multilevel mentalization based prevention program will lead to significantly greater improvements in well-being and mental health among children and parents compared to control groups, as measured at the post-intervention assessment. Secondary hypotheses: 1. A universal prevention program on mental health enhances help-seeking behavior and reduces mental health stigma among children, parents and teachers at post and follow-up measurement. 2. A universal prevention program on mental health improves classroom climate and increases teaching efficacy at post and follow-up measurement. 3. A multi-level mentalization based prevention program leads to greater improvements in well-being and mental health among children and parents than control groups, as measured at follow-up. 4. A multi-level mentalization based prevention program leads to greater improvements in parental efficacy and family adjustment in parents and reduces parental stress compared to control groups at post and follow-up measurement. 5. The longer intervention group will yield greater improvements in outcome measures compared to the shorter intervention group.
