Validation of two screening instruments for PTSD in Dutch substance use disorder inpatients

► We test the psychometric properties of two screening instruments for PTSD. ► The MINIplus (interview) and the SRIP (self-report) are compared to the CAPS. ► The MINIplus is inadequate in detecting PTSD in substance use disorder patients. ► The SRIP is a reliable screener for PTSD in substance use disorder patients.
