An interventional study of Empower@Home: An online cognitive-behavioral therapy self-care program for geriatric depression and Telephone friendly visits in Depression, sponsored by University of Michigan. Recruiting at 1 site in United States. Open to participants aged 50 Years and older. Per ClinicalTrials.gov, last updated 2025-11-21.
Sponsored by University of Michigan · Not applicable, Interventional, and Treatment
This study is a randomized Type I hybrid effectiveness-implementation trial aimed at evaluating the effectiveness of Empower@Home, an internet-delivered cognitive-behavioral therapy (CBT) program supported by aging service providers, in comparison to enhanced usual care for homebound older adults with depressive symptoms. A total of 256 participants will be randomly assigned to either the treatment group (Empower@Home) or the control group (enhanced usual care) in a 1:1 allocation ratio, with randomization stratified by participating agencies.
The primary aim of this study is to determine the clinical effectiveness of the Empower@Home program. It is hypothesized that participants receiving Empower@Home will show greater improvements in depressive symptoms at 12, 24, and 36 weeks after entering the study compared to those receiving enhanced usual care. Additionally, treatment moderators will be explored and a cost-effectiveness analysis will be conducted to assess the economic viability of the intervention.
The second aim is to investigate the mechanisms of change facilitated by the intervention using a mixed-methods approach. Causal mediation analysis will examine whether the acquisition of CBT skills, reduction in cognitive distortions, and increased behavioral activation, as well as participant engagement and the therapeutic alliance with the coach, mediate the treatment effects. Qualitative interviews with participants will be conducted to provide deeper insights into these mechanisms and enhance the interpretation of the mediation analysis.
The third aim focuses on evaluating the implementation process using the updated Consolidated Framework for Implementation Research (CFIR). This will involve a qualitative process evaluation to identify barriers and facilitators to the implementation of Empower@Home, drawing on perspectives from multiple stakeholders.
This study is a randomized Type I hybrid effectiveness-implementation trial designed to evaluate the clinical effectiveness and implementation process of Empower@Home, an internet-delivered cognitive-behavioral therapy (CBT) program tailored for homebound older adults with depressive symptoms. The trial compares Empower@Home, supported by aging service providers, to an enhanced usual care condition. The study involves 256 participants who will be randomly assigned to either the treatment or control group, with randomization stratified by agency.
Rationale: Depression is a significant public health concern among homebound older adults, with approximately 50% experiencing clinically significant depressive symptoms and 14% facing major depression-rates significantly higher than those of non-homebound counterparts. Homebound older adults often encounter barriers to accessing traditional mental health services, including physical disabilities, socioeconomic disadvantages, and racial or ethnic minority status. Empower@Home addresses these challenges by leveraging the existing workforce of aging service providers to support digital mental health interventions (DMHIs).
Intervention: Empower@Home is a nine-session, computerized CBT program enhanced with entertainment elements to increase engagement. The program is specifically designed for homebound older adults, incorporating age-relevant examples and a simplified user interface. It includes features such as a character-driven storyline, short videos, and interactive exercises to facilitate learning and engagement. The program is supported by lay coaches-aging service providers trained to offer weekly support calls, enhancing program adherence and personalization.
Study Aims:
Effectiveness: The primary aim is to determine the clinical effectiveness of Empower@Home compared to enhanced usual care. The hypothesis is that participants in the Empower@Home group will show greater improvements in depressive symptoms at 12, 24, and 36 weeks post-enrollment. Secondary clinical outcomes include improvements in anxiety, loneliness, social support, quality of life, disability burden, and pain severity.
Mechanisms of Change: The study will also explore the mechanisms through which the intervention produces change. Using a mixed-methods approach, the study will investigate whether CBT-related factors (e.g., skill acquisition, behavioral activation), engagement-related factors (e.g., narrative engagement), and coach-related factors (e.g., therapeutic alliance) mediate treatment effects. Qualitative interviews will complement these findings by providing participant perspectives on how the program facilitated behavioral change.
Implementation: The study will assess the implementation process using the updated Consolidated Framework for Implementation Research (CFIR). This qualitative process evaluation will identify barriers and facilitators to implementation from the perspectives of multiple stakeholders, including older adults, coaches, and agency staff. Data will be collected through interviews, meeting minutes, field observations, and other relevant sources, and analyzed using both traditional qualitative methods and natural language processing techniques.
Study Design: Participants will be recruited from 3 to 4 aging service agencies that serve as implementation sites. These agencies represent diverse service delivery models, enhancing the study's external validity. Participants will undergo remote assessments via phone at baseline, post-intervention, and follow-up intervals at 12, 24, and 36 weeks. The study will also employ a cost-effectiveness analysis, evaluating the economic viability of the Empower@Home program from a public healthcare payer perspective.
Expected Outcomes: The study is expected to demonstrate that Empower@Home, when supported by aging service providers, is more effective and cost-effective than enhanced usual care in reducing depressive symptoms and improving other psychosocial outcomes. Additionally, the findings will provide valuable insights into the barriers and facilitators to implementing DMHIs in community settings, offering guidance for future scalability and sustainability of such interventions.
Innovation: Empower@Home integrates user-centered design principles, community participatory research, and innovative engagement strategies, such as character-driven storytelling, to enhance user experience and therapeutic outcomes. The use of aging service providers as lay coaches not only addresses the shortage of mental health professionals but also aligns with the existing infrastructure of aging services, making the program highly scalable and sustainable.
This trial will contribute significantly to the growing body of evidence on the effectiveness of DMHIs in real-world settings and inform strategies for broader implementation within community-based aging services.

Exclusion Criteria:
Participants will be provided with access to a 9-session online program called Empower@Home, a self-help intervention based on cognitive behavioral therapy principles. The intervention has three components: 9 interactive self-paced online sessions, printed workbook that goes along the online sessions for exercises and homework, and telephone coaching by a trained staff from a social service agency serving older adults. Participants will have up to 12 weeks to try to complete the program with the support of a trained coach.
Behavioral: Empower@Home: An online cognitive-behavioral therapy self-care program for geriatric depression
Participants will receive enhanced care as usual, including care as usual from their social service provider and a psycho-educational handout. In addition, they will receive telephone friendly calls from a research staff every other week to mimic the human interactions provided by coaches in the experimental group.

Participants in the waitlist control group will receive attention control through biweekly telephone-friendly visitors. Trained project staff will call participants to provide companionship, emotional support, and a friendly conversation. In addition, the callers will conduct a biweekly assessment of depressive symptoms using the patient health questionnaire (PHQ-9), to mirror the biweekly in-app PHQ-9 assessments with the experimental group.
