Descriptive Information
Brief Title  ICMJE Neurocognition and Work Productivity in Major Depressive Disorder (MDD)
Official Title  ICMJE Neurocognition and Work Productivity in Major Depressive Disorder
Brief Summary This study will investigate the relationships between subjective cognitive complaints, neurocognitive deficits, and work productivity in participants with Major Depressive Disorder (MDD), before and after 8 weeks of treatment with an antidepressant medication. Our hypothesis is that, in working participants with MDD of at least moderate severity, neurocognitive deficits will predict poorer work functioning and productivity.
