Changes in Anxiety Symptoms and Their Correlates in Adolescents Participating in a School-Based Anxiety Prevention Program during the COVID-19 Pandemic

Anxiety disorders have been on the rise among adolescents over the past decade. The COVID-19 pandemic appears to have contributed to this increase, putting further pressure on often already overburdened health systems. Universal prevention programs may offer a potential solution, but few have been evaluated in the context of a pandemic. The objective of this article is to measure the impact of a universal prevention program--the HORS-PISTE program--on several anxiety-related variables in the context of a pandemic. The HORS-PISTE program consists of 10 workshops spread over the two first years of high school, secondary 1 and 2 (grade 7 and 8 equivalent). Workshops are held in a classroom setting and focus on the development of psychosocial skills. The study was conducted in Quebec with 1,202 secondary 1 and 2 students (48.7% girls, 51.3% boys) with an average age of 12.58 years ("SD" = 0.75). They completed an assessment protocol before and after participating in the HORS-PISTE program in the autumn of 2020. Their answers were subjected to descriptive analysis and multivariate analysis of variance. Results indicate a significant decrease in symptoms for several of the measured variables between the two measurement times, such as those associated with panic disorder, generalized anxiety disorder, and test anxiety. The results also show a decrease in some variables related to the interference of anxiety symptoms and the cognitive and behavioral vulnerabilities targeted by the program. The discussion highlights possible explanations for the results, as well as how universal prevention programs may contribute to the prevention of anxiety during adolescence, especially in a pandemic context.
