This study is for adults 60 years and older who are grieving the recent loss of a spouse or
partner. Bereavement is one of the most distressing transitions faced by older adults and
triggers dramatic changes to older adults' daily routine which puts them at-risk for a mood
disorder. The purpose of this study is to promote bereaved elders' mental health by focusing
on healthy lifestyle practices. Study treatment involves using a tablet to record their daily
physical activity, diet, and sleep behaviors, for 12 weeks. The investigators follow-up with
people for up to one year.
