The purpose of this study is to assess the feasibility, acceptability, and fidelity of an 8-week intervention where peer coaches will deliver depression care to adults 60 years of age or older who have depression and subjective cognitive decline.

With support from the MADRC ORE Core, we will recruit 30 community-dwelling older adults to conduct an open pilot study of PeersCOG. Trained and supervised peer coaches will deliver depression care to adults 60 years of age and older with depression and subjective cognitive decline in an 8-week intervention using video chats and texts. We will use mixed methods to assess feasibility, acceptability, and fidelity. We will use validated instruments to assess the preliminary outcomes, including depression, SCD, functioning, and social factors at baseline, 8 weeks, and 3 months, and we will conduct post-intervention interviews with stakeholders at 8 weeks. Older adult participants will be asked to name a study partner who will support the older adult throughout the study in terms of study enrollment. They may also have additional perspectives on the impact of impaired cognition and depression on daily living and related needs. The older adult will not be excluded if the study partner is not available.
