PSFP is an evidence-based psycho-educational program designed to strengthen family skills. It brings parents and their children together in workshops where the same topics are addressed, which enhances its effectiveness. Each session brings together a group of 10 families for 14 two-hour sessions (once a week). PSFP is designed for families with children aged 6–11 or 3–6. Positioned within the field of mental health promotion, it draws on the concepts of resilience, self-efficacy, social learning, and nonviolent communication. It fosters positive attention, communication, and emotion management, and lays the groundwork for positive discipline. Primarily implemented at the request of municipalities, its implementation protocol provides robust training for local partners and facilitators, enhancing their professional skills beyond the program itself. In an environment of kindness and practical experimentation with validated tools, it provides a framework for constructive and progressive dialogue where participants learn from one another’s experiences and expertise. It enables parents to broaden their parenting practices: it has rapid effects on family relationships and parents’ self-confidence. In the medium term, it improves: - parenting skills: sense of personal efficacy, communication, supervision, and commitment - children’s psychosocial skills: reduction in behavioral problems - mental health: anxiety and depression - family atmosphere and bonds. In the long term, it reduces initiation into and use of psychoactive substances.
