Gaze-Contingent Music Reward Treatment for PTSD

The present study is a double-blind trial that seeks to examine the feasibility, acceptability, and efficacy of a recently developed eye-tracking-based, gaze-contingent music reward therapy (GC-MRT) in individuals with posttraumatic stress disorder (PTSD). The specific aims of this study are to: (1) examine the efficacy of GC-MRT in PTSD; and (2) elucidate its underpinnings (i.e. attention control, reward processes, and exposure via counter-conditioning). The investigators hypothesize that: 1. GC-MRT will produce greater reductions in symptoms compared to PC at post-treatment and follow-up (diverting attention away from threat). 2. GC-MRT-exp will produce greater reductions in symptoms compared to PC at post-treatment follow-up (exposure via counter-conditioning by rewarding threat stimuli). 3. Exploratory analysis will compare the reductions in symptoms of GC-MRT compared to GC-MRT-exp at post-treatment follow-up.
