Stress is an adaptative reaction to the threats coming from our environment. We have survived to the Mammoths thanks to this stress system. Today, stress is becoming an issue of our modern society since it is becoming chronic. We are indeed invaded by situations that our brain interprets as being stressful. Yet, the science of stress has discovered how to deal with this chronic stress, and its bad consequences (overweight, hypertension, depression). The Centre for Studies on Human Stress has created the program Destress for Success in order to provide adolescents with a way to control their risk of chronic stress, at this time in their life where depression may suddenly occur. 
Destress for Success has been administered in 507 adolescents starting secondary schools. Results have shown that stress was reduced by half in the most stressed participants and that depression levels were reduced in almost every participants. 
The proposed research program is in the continuity of this result, and will assess the effects of the Destress for Success program in adolescents who are at high-risk of chronic stress: those who have experienced maltreatment, and who are staying in the Centres Jeunesse de Montréal, and the adolescents from Nunavik.Because we are living in the web 2.0 era, a mobile version of the program has been created, and will be tested in adolescents suffering from depression. Finally, we will test whether additionnal information from the Destress for Success program may improve the efficacy of the program leaded by the Fondation des Maladies Mentales , and called Solidaires pour la vie, to decrease the prevalence of depression in the Quebecer population.
