The association between trainer expertise and changes in adolescent symptomatology in an evidence-based family prevention programme.

Abstract

[eng] Purpose: The aim of this study is to assess whether the outcomes of implementations of the Universal Strengthening Families Program (SFP 11-14) are linked to the competences or specific skills of the trainers of social field who gave them. Method: The analyzed data was based on ratings awarded by the 174 mothers participating in the SFP 11-14. By conducting a K-means cluster analysis, significant groups were identified, based on the ratings awarded to the trainers. Results/Discussion: A comparison of the clusters led to the identification of significant differences between cluster 2 (trainers with limited skills) and the other clusters in terms of changes in the children's symptoms after participating in the SFP 11-14. Trainers with limited skills were associated with fewer changes in the symptomatology. It highlights the importance of proficient trainers in programme outcomes, and it could serve as a guide for the public social work in the design of EBP.
