Psychological Services Vol. 16, Iss. 1,  (Feb 2019): 58-66. DOI:10.1037/ser0000322 Youth are commonly exposed to potentially traumatic events (PTEs). Following exposure, approximately 25% develop persistent mental and behavioral health (M/BH) symptoms, yet many go untreated or are misdiagnosed and suffer adverse outcomes. Primary care is an ideal setting for detection of trauma-related symptoms. The current article uses archival data to (1) examine the prevalence of posttraumatic stress symptoms that are unlikely, possible, and likely to meet diagnostic criteria for posttraumatic stress disorder (PTSD) and the M/BH and physical health concerns that co-occur with PTSD symptoms among adolescents (n = 133, mean age = 15.1 years, 67% female, 60% White) referred for brief, integrated M/BH services within primary care and (2) identify the prevalence of referred adolescents with elevated symptoms of PTSD that would not be identified for services by traditional depression screening..
