This study represents Phase II of a research program involving an international collaboration with Macquarie University (Sydney, Australia) to implement an Internet-based cognitive behavior therapy for the treatment of anxiety and depression in French-speaking Canadians from the Atlantic Provinces.

The primary objective is to establish the clinical efficacy of a French-Canadian self-guided format version of the Wellbeing Course by conducting a randomized-control trial where an experimental group will be compared to a waitlist control group. A secondary objective is to demonstrate the course's acceptability through participants' satisfaction with the course.
