Brief summary
Randomized clinical trial of sertraline vs. placebo for post-TBI depression
Detailed description
Purpose: The purpose of this study is to document the efficacy of sertraline (Zoloft) in the treatment of depression (major depressive disorder) after TBI, including the impact on quality of life. Researchers will also explore the effects of sertraline on anxiety disorders, which often accompany post-TBI depression. Background: Major depression is experienced by many more people after TBI than prior to injury and more often than in people without a brain injury. Many studies have also shown that this higher than 'normal' incidence looms for many years post TBI. Major depression is associated with a variety of negative outcomes, including poorer functioning in basic activities, reduced employment, elevated divorce rate, reduced social and recreational activity and increased sexual dysfunction. Need for Research: Of the current drug treatments for major depression, sertraline and similar drugs (known as selective serotonin reuptake inhibitors, or selective serotonin reuptake inhibitor (SSRIs)) have few side effects in people who have experienced a brain injury and have been shown to be effective in people with no known brain injury. However, information on the impact of SSRIs on post-TBI depression, based on randomized, double-blind studies, is unavailable. Current Research Activity: Approximately 50 men and women volunteers who are post TBI and currently diagnosed with major depressive disorder are being randomly assigned to a 12-week period of taking Zoloft or a placebo. Over the period of study, participants will have the severity of their depressive symptoms assessed (as well as their symptoms of anxiety); a simple measure of the volunteer's perceived quality of life will be implemented prior to the study and at its termination. It is hypothesized that sertraline will reduce the symptoms of depression and anxiety and will increase the person's perceived quality of life to a significantly greater extent than will the placebo.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Depression at Baseline | baseline | The 17-item Hamilton Rating Scale for Depression (HAM-D) is a widely used clinician-rated measurement of depression severity. A score of 0-7 is considered to be normal. 8-13 = mild depression, 14-18 = moderate depression, 19-22 = severe depression, and ≥ 23 = very severe depression. Self-report of depression and DSM-IV diagnosis (HAM-D score) at baseline. |
| Depression at End of Treatment | end of treatment, average of 10 weeks | Self-report of depression and Diagnostic and Statistical Manual Diploma in Social Medicine (DSM-IV) diagnosis (HAM-D score) compared at end of treatment to baseline. Participants were considered treatment responders if their initial HAM-D decreased by 50% or dropped below a score of 10 at the end of the intervention.

It is typically administered twice during an evaluation, and the mean of the 2 obtained scores is used. Higher scores on this measure indicate higher levels of subjective QOL. Range from 1 to 7. |

Recruitment details
Participants were recruited through physician referrals and flyers posted in outpatient rehabilitation treatment areas and distributed at TBI-survivor groups. Participants from past research projects who had agreed to be contacted for future studies were contacted.
