The available evidence indicates that up to 50% of employees affected by major depression are undiagnosed, and usually go untreated.
Employers have a significant incentive to identify and treat employees who suffer from depression but are undiagnosed. On average, undiagnosed employees will miss from 22 to 32 workdays per year, and will incur incremental medical costs from $1,000 to $2,000 per year more than other employees.
