Safe & Sound Protocol in Adults With Trauma and SUD

Participants will complete a series of instruments after consenting to participate and have the SSP uploaded onto their mobile device or tablet. Participants will listen to the SSP for 3 to 5 hours over the course of 7 days. On the eighth day, participants will complete a follow-up set of instruments. The active arm will deliver the actual SSP intervention whereas the sham arm will deliver unfiltered music.
