To facilitate easily accessible screening for trauma-related symptoms, a web-based application called Smart Assessment on your Mobile (SAM) was developed. In this study, we examined whether SAM was able to accurately identify posttraumatic stress disorder (PTSD) and depression in adults. Eighty-nine referred police officers completed SAM, containing the PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 (PCL-5) and the Depression Anxiety and Stress Scale (DASS-21), on their own device prior to a diagnostic interview where the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) and Structured Clinical Interview for DSM-IV (SCID-I/P) were administered. Results showed a substantial agreement between SAM and the diagnostic interview in the assessment of PTSD and depression. An optimal trade-off between sensitivity (89%) and specificity (68%) levels was found at a cut-off score of 31 on the PTSD Checklist for DSM-5 (area under the curve=0.845, 95% CI [0.765, 0.925], diagnostic odds ratio=15.97). This is one of the first studies to support the validity and reliability of a mobile screener following trauma. SAM may facilitate screening for trauma-related symptoms on a large scale and could be a first step in a stepped-care model for trauma survivors to help identify individuals who need further diagnostics and care.
