Transdiagnostic Internet Cognitive-behavior Therapy for Mixed Anxiety and Depressive Symptoms in Postnatal Women

This research project aims to examine the acceptability and efficacy of a French-Canadian adaptation of a postnatal anxiety and depression program. The main question it aims to answer is:

\[1\] When the adapted postnatal Internet-delivered cognitive behavioral therapy (iCBT) is added to treatment as usual (TAU) in community-based care for women with anxiety and depressive symptoms, is the iCBT+TAU condition more effective to reduce symptoms than TAU alone?

Participants will:

postnatal iCBT group -\> Answer questionnaires before, after (week 6) and 4 weeks after the intervention (week 10); do the 6-week non-guided iCBT program for anxiety and depressive symptoms during the postnatal period.

Waitlist, TAU group -\> Answer questionnaires at enrolment, at week 6 and week 10. Participants will have access to the intervention after they complete their last questionnaires.
