This is according to a study published in the Canadian Medical Association Journal. The study found that over 75% of recent research on depression prevalence has been based exclusively on patient completed questionnaires.</p> Thu, 18 Jan 2018 14:28:57 +0000 mona.noonoo@mail.mcgill.ca 32843 at /newsroom
