PTSD Symptom Scale – Self-Report Version

PTSD Symptom Scale – Self-Report Version (PSS-SR) is a 17-item self-reported questionnaire to assess symptoms of posttraumatic stress disorder. Each of the 17 items describe PTSD symptoms which respondents rate in terms of their frequency or severity using a Likert-type scale ranging from 0 (not at all or only one time) to 3 (almost always or five or more times per week).
