Brief Summary
After losing a loved one, most successfully navigate acute grief and adapt to the loss within about 1 year, but in about 10%, prolonged grief disorder (PGD) ensues. This study is anticipated to provide novel evidence regarding the neurobiological mechanisms of PGD in older adults. The biological alterations identified here could provide targets to elucidate how currently available therapies work and inform novel mechanism-based interventions for treating late-life PGD.

Outcome Measures
Primary Outcomes (1)
Score on the Prolonged Grief 13-Revised (PG-13-R) scale
We will measure change in the PG-13-R score from baseline to end of study. The PG-13-R scores range from 10 - 50 (higher scores indicate more severe grief symptoms).
Baseline through study completion, up to 10 weeks
Study Arms (3)
Yoga
EXPERIMENTALParticipants will engage in 10 weekly IY classes
Socialization Control
ACTIVE COMPARATORParticipants will engage in 10 weekly socialization control group sessions
Waitlist Control
OTHERWaitlist Control
Interventions
Participants will engage in 10 weekly socialization control group sessions
Upon Step 1 study completion (week 10), participants in this group who continue to meet PGD criteria on the SCIP will enter Step 2 phase
