Guideline summary by EveryOption

Canada’s CANMAT 2023 guideline for adults with major depressive disorder reports that twice-weekly CBT sessions for depression show improved outcomes compared with once-weekly sessions. This describes session frequency in the evidence the guideline reviewed; a local provider’s schedule and an individual’s needs may differ.
