'Curing' depression?

Canadian Medical Association Journal

Determining when treatment of a depressed patient can safely be discontinued is important but difficult for clinicians; until now, no tests have been available that are simple to administer in a doctor's office. Roger McIntyre and colleagues developed a brief 7-item questionnaire to determine if a patient with depression has recovered, and have now evaluated it for use in primary care.

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.
