Depression is likely the most prevalent and disabling psychological complication associated with spinal cord injury (SCI). Yet no controlled depression treatment trials have been performed in this population. The proposed study is a multi-site, randomized, double-blind, placebo controlled trial of venlafaxine XR (Effexor XR) in 133 adults with SCI and major depressive disorder (MDD) or dysthymia who are at least one month post injury. Participants will be recruited from four SCI Model System sites, the University of Washington, Rehabilitation Institute of Chicago, University of Michigan, University of Alabama, Birmingham and Baylor Institute for Rehabilitation, Dallas, TX. The purpose of the study is to examine the efficacy and tolerability of venlafaxine XR as a treatment for MDD. The primary outcome will be the percent of responders (those who report at least a 50% reduction in depression severity from baseline to the end of treatment) in the venlafaxine XR versus placebo control group using intent-to-treat analysis. Secondary outcomes will include changes in pain, health related quality of life depression-related disability and community participation. A successful clinical trial could lead to more aggressive identification and treatment of MDD as well as improved health and quality of life in this important population.
