Summary

Large samples (\~2,000/yr) of adult undergraduate students at a large southern university will be pre-screened via the University of Kentucky SONA System (IRB#43626) to identify and recruit adult female participants who report a history of IPV and probable PTSD to participate in a one-day lab study. After completing an IRB-approved informed consent, participants will complete a brief psychiatric diagnostic interview and a battery of questionnaires. They will then complete three blocks of the Stop Signal Task (SST). Participants will be randomized (double-blind, stratified by PTSD diagnosis and psychotropic medication use) to receive 15-min of active or sham multifocal tDCS targeting the rIFG. tDCS will be delivered offline for 11.5-mins after block 1 of the SST and online for 3.5-mins during block 2 of the SST. Sham stimulation will be identical to active tDCS, but electrical current will only be ramped in/out at the beginning and end of the 15-mins. The third block of the SST will be completed after tDCS. Lastly, participants will complete a pictorial trauma-related symptom provocation task. Participants will be compensated with course credit.

Conditions

  • Post Traumatic Stress Disorder

Interventions

DEVICE

tDCS

Subjects will receive 20 minutes of multifocal transcranial direct current stimulation. The anode will be placed over the frontal pole (FC6, 10-10 EEG) and will be surrounded by 5 return electrodes (cathodes). Current will be set at 1.5mA and will be ramped in/ out at the beginning and end of the 15-minutes of stimulation over the course of 15 seconds.
