PROJECT SUMMARY/ABSTRACT
More than four million U.S. residents seek treatment for substance use disorder (SUD) each year.
Community reintegration following residential SUD treatment is an especially vulnerable time, withmost people
who return to use following residential SUD treatment doing so in the 30 days immediately following discharge.

These data underscore affect dysregulation—a widely regarded transdiagnostic risk
factor—as a key target for interventions to be delivered during community reintegration of SUD inpatients. Yet,
knowledge/methodological/population gaps limit our understanding of affect dysregulation in SUD. (1) Virtually
all research on return to use during community reintegration has used cross-sectional or traditional longitudinal
designs. Pinpointing real-time proximal predictors of return to use is necessary to inform interventions that can

for people with SUD. Research during this period is severely limited. Studies must examine whether findings to
inform interventions for this population will be useful for most people who experience community reintegration.
Addressing these critical gaps, we propose integration of subjective data from EMA with physiology from
the Empatica Embrace2, collected in individuals' (N=300) natural settings during the 30 days after residential
SUD treatment. Aim 1 identifies features of negative and positive affect dynamics that predict return to use
outcomes during community reintegration of SUD inpatients. Aim 2 tests theutility of physiology from a
wearablebiosensor in detecting return to use. Aim 3assesses the extent to which features of affect dynamics
and physiology proximally predict return to use across diverse demographic and clinical groups.
Findings will inform evidence-based tools to prevent/delay return to use during community reintegration.
