No results posted yet for this study

Summary

The purpose of this study is to assess impact of repetitive transcranial magnetic stimulation (rTMS)+Episodic Future Thinking (EFT) vs. sham rTMS+EFT on delay discounting and methamphetamine (MA) demand, on vividness of future positive events during EFT training and on frequency of episodic thinking during the week following EFT training

Conditions

  • Methamphetamine Use Disorder

Interventions

BEHAVIORAL

EFT

Participants will identify three personalized and rewarding future events not related to drug use that take place 1 week, 1 month, and 6 months in the future. Participants will be asked to rate the vividness of each personalized future positive event on a 5-pt Likert scale.A brief and personalized EFT prompt will be created for each future event . Personalized EFT prompts will be presented during delay discounting and MA demand assessments following EFT training. Participants will also receive daily text/email messages with these prompts, reminding them to engage in EFT, vividly reexperience their future events, over the week following EFT training.

DEVICE

high frequency rTMS

TMS will be delivered with a MagVenture Mag Pro R30 with the Cool-B70 A/P coil with active liquid cooling . For dlPFC, we will measure position F3. The first session will begin with the acquisition of the resting motor threshold on the contralateral hand. Intermittent theta burst stimulation (iTBS) (triplet 50 Hz bursts, repeated at 5 Hz, 2 sec on and 8 sec off; 600 pulses per session) will be delivered at 110% of the resting motor threshold (RMT) and will last \~3 minutes. Participants will receive 2 sessions of iTBS to the dlPFC brain region with a 15-20-minute interval between sessions

DEVICE

sham frequency rTMS

Participants will receive sham TMS to the dlPFC. They may feel the TMS from the A/P coil electrodes, but there will not be any real stimulation of the brain.
