Protocol - PTSD Screener - DSM-IV

Add to My Toolkit
Description:

The Primary Care-PTSD Screen (PC-PTSD-IV) for The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) is a self-administered instrument that includes four yes/no items that capture post-traumatic stress disorder (PTSD)-related experiences in the past month. It is designed to be used in primary care settings but is not restricted to those settings. It has most often been used to screen for PTSD in veterans at the U.S. Department of Veterans Affairs but is not limited to military-related PTSD. Screening with PC-PTSD-IV is considered positive if the respondent answers yes to any three items. Provisional PTSD status based on screening typically requires verification with a structured interview for PTSD such as the Clinician-Administered PTSD Scale (CAPS; see PTSD Symptoms, Severity and Diagnosis).

Adults, ages 18 and older

Specific Instructions:

This measure includes both the DSM-IV and DSM-5 versions of the Primary Care-PTSD Screen. The PhenX PTSD Working Group anticipates that scientific demands will dictate that researchers typically collect data in accordance with the most recent PTSD criteria and will use the DSM-5 version of the protocol. However, under special circumstances (e.g., when adding to older, existing data sets), researchers may decide to use the DSM-IV version instead

The PC-PTSD and the Diagnostic Interview for Genetic Studies (DIGS) protocol included in the Post-traumatic Stress Disorder measure in the PhenX Psychiatric Domain collect similar information. Therefore, selecting both the PC-PTSD Checklist and DIGS will result in overlapping protocols. In contrast to the PC-PTSD, the DIGS excludes (i.e., skips out) participants that do not meet Criterion A2 (intense feelings of fear, helplessness, or horror).

Selection Rationale

The Primary Care-PTSD Screen (PC-PTSD-IV) for The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) is a brief, widely used, psychometrically sound instrument that has been shown to accurately identify patients who may qualify for a PTSD diagnosis. PC-PTSD-IV provides investigators with the ability to collect screening data that are consistent with prior foundational work on PTSD.
