title: Validation of two screening instruments for PTSD in Dutch substance use disorder inpatients.
abstract: Posttraumatic stress disorder (PTSD) is highly prevalent in substance use disorder (SUD) populations. Because resources for extensive and thorough diagnostic assessment are often limited, reliable screening instruments for PTSD are needed. The aim of the current study was to test two short PTSD measures for diagnostic efficiency in predicting PTSD compared to the Clinician-Administered PTSD Scale (CAPS). The sample consisted of 197 SUD patients receiving residential substance use treatment who completed questionnaires regarding substance use and trauma-related symptoms, all abstinent from substance for 4weeks. The PTSD section of the Mini International Neuropsychiatric Interview plus (MINIplus) and the Self-Report Inventory for PTSD (SRIP) are compared to the CAPS. Results showed low sensitivity (.58) and high specificity (.91) for the PTSD section of the MINIplus. The SRIP showed high sensitivity (.80) and moderately high specificity (.73) at a cut-off score of 48. The prevalence of PTSD as measured with the CAPS was 25.4% current and 46.2% lifetime. Results indicate that the MINIplus, a short clinical interview, has insufficient quality as a screener for PTSD. The SRIP, however, is a reliable instrument in detecting PTSD in a SUD inpatient population in The Netherlands. Screening for PTSD is time efficient and increases detection of PTSD in SUD treatment settings.
