The results in intent to treat analyses showed significant improvement in PTSD (CAPS (t(19) = 4.8, P < .001)) in the MBCT groups, but not the TAU conditions. There was also a significant Condition × Time interaction in the MBCT completers (F[1,35] = 16.4, P < .005).
In addition, MBCT completers (n = 15, 75%) showed good compliance with assigned homework exercises, and significant and clinically meaningful improvement in PTSD symptom severity on posttreatment assessment in CAPS and PDS (particularly in avoidance/numbing symptoms), and reduced PTSD-relevant cognitions in PTCI (self blame).
[Ed Note: However it’s important to note that 15 out of 80 subjects completing the program is not a strong percentage.]
The investigators conclude that these data suggest group MBCT may be an acceptable brief intervention/adjunctive therapy for combat PTSD, with potential for reducing avoidance and PTSD cognitions.
Further studies are needed to examine efficacy in a randomized controlled design and to identify factors influencing acceptability and efficacy.
