L’implémentation d’interventions abordant la santé mentale et exerçant des compétences psychosociales auprès des collégiens rencontre en France certaines difficultés. Plusieurs dispositifs innovants conçus par une équipe interdisciplinaire sont présentés. Cela souligne l’intérêt de développer des méthodes adaptées aux adolescents et ajustées au contexte scolaire, en croisant les apports de la psychologie et du design social, et avec la contribution des acteurs locaux.

Background: the mental health of students was particularly affected by the COVID-19 pandemic. The present study therefore examined the relationships between anxiety and depressive symptoms, eating-related problems, coping, fear of COVID-19, and intolerance of uncertainty. Methods: 2139 French students of 54 universities were recruited in the different regions of France during a French lockdown (between 21 April and 3 May 2021). Six variables were measured: fear of COVID-19, intolerance of uncertainty, coping, anxiety and depressive symptoms, and eating-related problems. To explore the directions of the relationships between our variables of interest, we calculated a directed acyclic graph. Results: our data highlighted the central roles of intolerance of uncertainty in students’ anxiety and depressive symptoms, and the direct role of prospective intolerance of uncertainty on eating-related problems. Conclusions: these findings indicate that intolerance of uncertainty should be targeted by interventions designed to help students with high levels of anxiety, depressive symptoms, and/or eating-related problems.
