In a randomized controlled trial involving 454 patients with major depressive disorder across 47 medical practices in 4 provinces, outcomes of antidepressant therapy were determined with the brief HAMD-7 questionnaire or the standard longer questionnaire (the HAMD-17) that is used in research and specialty settings. Results from the 2 study instruments showed good agreement, which suggests that the shorter version is accurate and could be used in clinical practice by physicians.
A copy of the HAMD-7 is provided as an appendix to the article, and is available to journalists.
