Excerpts from Study:

A new study from the Centre for Addiction and Mental Health CAMH (in Canada) has found that employees with depression who receive treatment while still working are significantly more likely to be highly productive than those who do not. This is the first study of its kind to look into a possible correlation between treatment and productivity.

People who experienced a depressive episode were significantly less likely to be highly productive, the study showed. “We expected this, as past research has found that depression has adverse effects on comprehension, social participation, and day-to-day-functioning,” said Dr. Carolyn Dewa, Head of CAMH’s Centre for Research on Employment and Workplace Health and lead author.

“What’s exciting is we found that treatment for depression improves work productivity. People who had experienced a moderate depressive episode and received treatment were 2.5 times more likely to be highly productive compared with those who had no treatment,” she says.  “Likewise, people who experienced severe depression were seven times more likely to be high-performing than those who had no treatment.”
