Objective: PTSD in female veterans and service members (SMs) is understudied, and new, effective treatments for PTSD are needed. Reconsolidation of Traumatic Memories (RTM) is a brief, manualized treatment for PTSD previously piloted in RCTs of male veterans and SMs. Here we examine RTM's effect on military women with PTSD. Method: We report a waitlist RCT using 30 military-connected females with DSM-IV-TR PTSD diagnoses, including current-month nightmares or flashbacks. Trauma types include military sexual trauma, other sexual traumas, combat, and other trauma types. Participants were randomized to treatment or waitlist. Of those enrolled, 97% completed treatment. Independent psychometricians, blinded to treatment condition, evaluated participants at intake, postwait, and two weeks post. The clinician took follow-up measures at six months and one year. The primary measure was the PTSD Symptom Scale-Interview (PSS-I). The secondary measure was the PTSD Checklist. Participants received up to three 120-min sessions of RTM. Results: RTM eliminated intrusive symptoms and significantly decreased symptom scale ratings in 90% (n = 27) of participants, versus 0% of controls (p < .001). Two-week treatment group PSS-I scores dropped 33.9 points versus 3.9 points for postwait controls (g = 3.7; 95% CI [2.5, 4.8]; p < .001). Treatment results were stable to 1 year. Conclusions: RTM effectively treated PTSD, independent of trauma source in female SMs and veterans effectively replicating previous results in male populations. Further research is recommended.
