Outcome Measures
Primary Outcomes (1)
Clinician Administered Posttraumatic Stress Disorder Scale
The Clinician-Administered PTSD Scale (CAPS) \[33\] : is a structured interview developed to diagnose PTSD and rate its severity. It is comprised of 30-items to assess PTSD-related symptom frequency and severity. Total scores (sum of 3 clusters items) range from 0 to 136, with scores classified as follows: subclinical, from 0 to 19; mild, from 20 to 39; moderate, from 40 to 59; severe, from 60 to 79; extreme, 80 and above. CAPS has 3 subscales characterized by the sum of all symptoms for each cluster: CAPS 1 (Revivesce/intrusive recolllections, 5 symptoms, score range: 0-28); CAPS 2 (avoidance, 7 symptoms, score range: 0-36); and CAPS 3 (hyperarousal, 5 symptoms, score range: 0-28). CAPS scoring: each symptom scores range from 0 to 4, plus 0-2 scores for frequency, and 0-2 severity.
