The PTSD Checklist – Military Version (PCL-M; Weathers, Litz, Huska, & Keane, 1994) consists of 17 self-report items congruent with the DSM-IV criteria for PTSD. It assesses severity of symptoms on a 1 (not at all) to 5 (extremely) scale and indicates respondent’s level of distress in the past month.
The Mississippi Scale for Combat-Related PTSD (M-PTSD; Keane, Caddell, & Taylor, 1988) is a 35-item questionnaire that assesses PTSD symptoms on a 1 to 5 frequency scale. A cutoff score of 107 indicates the presence of PTSD, although a score of 100 has also been used.
The Combat Exposure Scale (CES; Keane et al., 1989) assesses frequency of combat experiences on a Likert-type 1 to 5 scale with responses ≥ 3 indicating extensive exposure to death and life-threatening circumstances. Total scores range from 7 (no combat exposure) to 35 (extreme exposure).
