depression affects up to 40% of homebound seniors but most homebound seniors do not receive psychotherapy due to various access barriers. the study team focuses on developing community-based solutions to reduce these access barriers. in a previously approved project hum00207612, the study team tested the feasibility of a novel internet-based cognitive behavioral therapy (icbt) program called empower@home. the pilot project allowed refining study procedures and the web platform used to deliver the program. in this new project, the study team will conduct a larger single group study to test the effectiveness of empower@home with older adults. recruitment methods include 1) referrals from social service agencies and 2) advertisements on social media and the program website. the intervention involves attending up to 9 pre-recorded online therapy sessions and receiving weekly coaching calls from trained research assistants for up to 10 weeks. participants will engage in therapy in their private homes. three assessments are scheduled, including a comprehensive baseline, a post-test, and a 10-week follow-up. each assessment takes about 40 minutes to complete over the phone or via an online survey, depending on the participants' preference. subjects will be recruited from agency referrals and advertisements. between may 2022 and dec 2023, about 300 subjects will be recruited into a single group study design where all eligible and consented participants will receive the intervention immediately without waiting.
