Hypnosis for PTSD: Evidence Based Placebo-Controlled Studies

Abstract

Barabasz A and Barabasz M

A single manualized abreactive hypnosis session (5-6 hours) based on Ego State Theory (EST) was recently subjected to two placebo-controlled investigations meeting evidence-based criteria. Thirty-six patients in study #1 and 30 patients in study #2 who met PTSD criteria were exposed to either 5-6 hours of a manualized treatment or a placebo in a single session. Abreactive hypnosis emphasized hypnotically activated “reliving” of the trauma experience to physical and psychological exhaustion. In study #1 hypnosis and control group’s reduced PTSD checklist (PCL) scores immediately post treatment (placebo PCL score mean reduction 17. 34 and EST treatment PCL mean reduction 53.11). However, only the hypnosis patients maintained significant treatment effects at followups. Study #2 used the Davidson Trauma Scale (DTS), Beck Depression II (BDI – II), and Beck Anxiety Scales (BAI). Only the hypnosis group showed significant positive effects from pretreatment to all post treatment measurement periods. Abreactive EST was shown to be a highly effective and durable treatment for PTSD. Apparently, EST works because it is emotion focused, activates sub-cortical structures, and because the supportive, interpretive therapist reconstructs the patient’s personality to be resilient and adaptive.
