The M-PTSD is a 35-item self-report measure that assesses combat-related PTSD in veteran populations. Items sample DSM III symptoms of PTSD and frequently observed associated features (substance abuse, suicidality, and depression). Respondents are asked to rate how they feel about each item using 5-point, Likert-style response categories. Ten positively framed items are reversed scored and then responses are summed to provide an index of PTSD symptom severity which can range from 35-175. Cutoff scores for a probable PTSD diagnosis have been validated for some populations, but may not generalize to other populations.
"Before I entered the military I had more close friends than I have now." (Respondents are asked to rate item from 1 = "not at all true" to 5 = "extremely true.")
A ten item form, Miss-10, is available. (Hyer et al., 1991). M-PTSD-DS is an adapted version appropriate for Desert Storm War Zone personnel. Also, a parallel version exists for administration to spouses/partners (Taft et al., 1999).
There is also the Revised Civilian Mississippi for civilian samples.
