Comparing Standard vs. Modified Reconsolidation Blockade for the Treatment of Psychological Trauma
Summary
The investigators propose to examine a mismatch-based method of reconsolidation blockade for the treatment of psychological trauma in military personnel and Federal police officers. The standard reconsolidation blockade treatment (aka Reconsolidation Therapy) involves reactivating the trauma memory while under the influence of propranolol. The mismatch method of Reconsolidation Therapy will involve varying the contexts in which the weekly trauma memory retrieval will occur. This study will involve 10 visits (eligibility assessment, treatments, and follow-up visits) over a 6-month period for each participant. Treatments will be conducted once a week for a six-week period where the participant will take a dose of propranolol (or a placebo pill) 60 minutes prior to memory reactivation. The investigators hypothesize that reconsolidation blockade treatment will be as effective in treating PTSD among military personnel and Federal police officers, with the mismatch condition showing greater symptom improvement.
