Empower@Home: Hybrid Effectiveness-Implementation Randomized Controlled Trial (RCT)

Summary

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.

Conditions

• Depression

Interventions

OTHER

Telephone friendly visits

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.

BEHAVIORAL

Empower@Home: An online cognitive-behavioral therapy self-care program for geriatric depression

Empower@Home is an online self-help intervention based on cognitive behavioral therapy principles designed to treat depressive symptoms in older adults. 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. The online sessions contain entertainment elements in the form of a character-driven story of a homebound older adults, video-based psycho-educational content, voice-over instructions, interactive exercises, and weekly home practice assignments.
