What this trial studies

This interventional study compares a peer-delivered grief support program (RIVER) with enhanced care as usual for people bereaved by unintentional drug overdose. Participants are identified through collaborating medical examiner offices and work with Peer Support Community Partners alongside research teams from RAND and Stanford. Eligible adults (18+) who lost a loved one to an unintentional overdose within the past year and who can consent will be enrolled; people with active suicidal ideation or recent psychiatric hospitalization are excluded. Outcomes will include measures of prolonged grief, substance use, PTSD, depression, and related risk behaviors.

Who should consider this trial

Good fit: Adults 18 and older who fluently read English or Spanish, can give consent, and who lost a loved one to an unintentional drug overdose within the past year are the intended participants.

Not a fit: People with active suicidal ideation, those requiring psychiatric or substance-use hospitalization, anyone whose loss was more than one year ago, or whose loved one died by suicide or undetermined intent may not be appropriate or benefit from this program.

Why it matters

Potential benefit: If successful, the program could reduce prolonged grief symptoms and lower the risk of substance misuse and suicidal thoughts among people bereaved by overdose.

How similar studies have performed: Peer grief support interventions have shown promise in bereavement and behavioral health settings, but rigorous trials specifically targeting overdose bereavement remain limited.
