The present paper describes the development of the National Stressful Events Survey for PTSD-Short Scale (NSESSS-PTSD), a new self-report scale for PTSD that is brief (9 items), free of copyright restrictions, and consistent with DSM-5 diagnostic criteria. Study 1 describes the development of the NSESSS-PTSD scale items, which were reduced from a larger pool of items that were administered to a subsample of individuals with probable DSM-5 PTSD diagnoses from a large national sample. The resultant scale included items from each criterion and demonstrated high internal consistency. Study 2 evaluates the psychometric properties of the NSESSS-PTSD in a trauma-exposed non-clinical sample. Strong psychometric properties were observed in the sample, including convergent validity (through comparison to the DSM-IV Posttraumatic Stress Disorder Checklist), internal consistency, and the presence of a single dominant factor. Limitations of the present studies are discussed and specific recommendations for the next steps in the validation process are provided.
