Table 1.

Demographic, trauma history, and PTSD symptom data for the study sample. The participants in the two treatment conditions (TMT, No-TMT) do not differ on any of these variables; the two diagnostic groups (PTSD, No-PTSD control) are matched on demographic variables but differ in the degree of traumatization and symptom severity. Childhood trauma was assessed using the Childhood Trauma Questionnaire (CTQ); adult trauma was assessed using the Traumatic Events Interview (TEI); PTSD symptoms were assessed using the PTSD Symptom Scale (PSS); depression symptoms were assessed using the Beck Depression Inventory (BDI).

	TMT (n = 17)	No-TMT (n = 16)	TMT vs. No-TMT	TMT (n = 29)	No-TMT (n = 38)	TMT vs. No-TMT
