Trial Outcomes & Findings for Integrated Treatment of OEF/OIF Veterans With PTSD & Substance Use Disorders (NCT NCT01338506)

NCT ID: NCT01338506

Last Updated: 2020-02-11

Results Overview

The hypothesis is that COPE will significantly exceed the treatment as usual control group in reducing Change in Post-traumatic Stress Disorder symptoms as measured by a reduction of 25 points or more in scores for the Clinician Administered Post-traumatic Stress Disorder Scale (CAPS). A lower Clinician Administered Post-traumatic Stress Disorder Scale and Post-traumatic Stress Disorder Checklist score would indicate less severe Post-traumatic Stress Disorder/better outcomes. A negative sign in front of a number represents a decrease in score and better/positive outcomes. A greater decrease in a score represents greater improvement in symptoms (more positive outcomes). Clinician Administered Post-traumatic Stress Disorder Scale (CAPS): scores range 0-136 0-19: asymptomatic/few symptoms 20-39: mild PTSD/subthreshold 40-59: moderate PTSD/threshold 60-79: severe PTSD symptoms ≥80: extreme PTSD symptoms Post-traumatic Stress Disorder Checklist: score range 17-85.

PRIMARY outcome

Timeframe: Following 12 weeks of therapy.

Score of PTSD from Clinician Administered PTSD Scale (CAPS) and self-administered PTSD Checklist for DSM-5 PTSD Diagnosis (PCL-5). Lower scores on CAPS and PCL would indicate less severe PTSD. A lower Clinician Administered Post-traumatic Stress Disorder Scale and Post-traumatic Stress Disorder Checklist score would indicate less severe Post-traumatic Stress Disorder/better outcomes. A negative sign in front of a number represents a decrease in score and better/positive outcomes. A greater decrease in a score represents greater improvement in symptoms (more positive outcomes).

PRIMARY outcome

Timeframe: After 12 weeks of treatment

Clinician Administered PTSD Scale Itemized Scores Within the assessment there are 20 symptoms of PTSD, each with an individual score. A lower score would represent a better outcome (ie less severe symptom). The three itemized symptoms listed below represent hallmark traits/symptoms of PTSD. Overall score range 0-136 Reexperiencing Symptoms range 0-40 Avoidance/Numbing range 0-56 Hyperarousal range 0-40
