This presentation was given at the seminar on psychosocial skills (PSS) organized by Santé publique France from February 3 to 5, 2025, in Aubervilliers. Béatrice Lamboy, scientific advisor and co-leader of the PSS program at Santé publique France, presents a scalable PSS training kit, which serves as the foundation for PSS training under the interministerial strategy. It is based on Santé publique France’s 2022 and 2025 PSK frameworks. She also presents the introductory PSK sheet covering the fundamentals of PSK, as well as the PSK self-assessment grid (based on the 55 knowledge and skills of the 20 specific PSKs).
