Trial Outcomes & Findings for Effectiveness of Peer-Delivered Trauma-Specific Treatment (NCT NCT02081417)

Because of this difficult to engage population, participants were consented and baseline data collected after they were randomized to a study arm and completed their first treatment group.

Effectiveness of Peer-Delivered Trauma-Specific Treatment

PTSD Symptoms will be measured by the post-traumatic symptom checklist - civilian version. Responses are summed to yield a total severity score, with the full range for total scores being 17 to 85 (higher scores mean higher severity).

The Coping Scale will be used to assess coping skills. The Coping Scale directly assesses the degree to which participants report using 17 specific coping skills from SS, scaled from 0 (not at all) to 5 (extremely). This scale was selected as it is the most widely used measure of coping in the SS literature. As a result we will be able to directly compare our findings to other studies. Higher scores indicate greater frequency of use of coping skills with the range of total scores being 0 to 90

Drug and alcohol problem severity will be assessed using the drug and alcohol subscales of the Addiction Severity Index (ASI). Items assess frequency of drug and alcohol use and abuse within the past 30 days, how bothered the individual is by his/her drug or alcohol problems, and the importance of treatment. Higher composite scores indicate more severe problems. The ASI questions focus on two distinct time periods: the past 30 days and lifetime. A number of studies have confirmed the reliability and validity of the ASI.

Overall mental health and physical health will be assessed by the subscales of the SF-36 (short form 36). The SF-36 questions measure functional health and well-being from the patient's point of view. It is a practical, reliable, and valid measure of mental and physical health that can be completed in five to 10 minutes. The SF-36 has proven useful in differentiating the health benefits produced by different treatments. The Component Summary Scores range from 0% to 100% with higher scores indicative of higher functioning
