We examined the psychometric properties of the PTSD Checklist (PCL), a self-report instrument designed to assess symptoms of posttraumatic stress disorder. Three hundred ninety-two participants recruited in a university setting completed the PCL in addition to several well-established self-report instruments designed to assess various forms of psychopathology (e.g., depression, general anxiety, PTSD). Ninety participants returned for readministration of selected measures. Findings provided support for psychometric properties of the PCL, including internal consistency, test-retest reliability, convergent validity, and discriminant validity. Additional strengths of the PCL are discussed.
