Is this trial a fit for you?

Likely a good fit

Adults aged 18 to 75 in residential SUD treatment with a history of trauma and English proficiency who can provide consent and comply with study procedures.

Probably not a fit

Individuals without trauma history or who do not engage with the SSP protocol may not experience benefit.

What this trial studies

This interventional study randomizes 129 adults in residential treatment for substance use disorders and with a trauma history to either active or sham Safe and Sound Protocol (SSP) in addition to treatment as usual. Participants will use the SSP for 3 to 5 hours over seven days, and outcomes will be collected before and after the intervention, focusing on affect, anxiety, personality, mindfulness, and PTSD symptoms. The SSP is based on polyvagal theory and aims to modulate autonomic regulation through targeted music, with prior pilot data suggesting reductions in anxiety and trauma-related symptoms. This will be the first study to examine SSP effectiveness specifically in individuals with co-occurring SUD and trauma. Real-world data from SSP users indicate potential symptom reductions, though evidence in this population is still developing.

Why it matters

Potential benefit: If successful, SSP could provide a non-pharmacologic adjunct to improve anxiety and trauma-related symptoms for people in SUD treatment.

How similar studies have gone: Previous SSP work in other populations showed reductions in anxiety and trauma symptoms, but this is the first trial in adults with co-occurring SUD and trauma.
