Meru Health Ascend Mobile Intervention for Depression in Middle Aged and Older Adults

Phase 2

Completed

Brief Summary: Using technology to deliver depression interventions is one way could alleviate the public health burden of depression. The study is testing a mobile app intervention program for depression that uses cognitive behavioral skills and mindfulness. This study seeks to obtain feedback on the intervention and refine the intervention and then test the intervention in a larger study. The mobile app intervention called the Meru Health Ascend program consists of the app and therapist support via messaging within the app.

Detailed Description: The Meru Health Ascend program is a guided self-management program that uses a mobile application to deliver content of the intervention. A licensed therapist (Meru Health employed) provides support to participants as needed and reviews practice logs within the app.The 8-week program teaches cognitive behavioral techniques and mindfulness skills with the aim of improving the user's mental health. The platform provides informational videos, skills practices, group discussion, and messaging with the therapist. The Meru Health program enrolls participants in treatment groups that work through the program at the same time and can provide support to on another on the discussion board within the app.

We are conducting two studies in middle aged and older adults with elevated depressive symptoms to evaluate the Meru Health Ascend program. In the first study (study 1), we will examine the feasibility of the intervention in individuals aged 40 years or older with elevated depression symptoms using an iterative case series. Specifically, we will examine the usability of app and materials, dropout and reasons for dropout, and user perceptions of the program.

We will then conduct a proof-of-concept study (study 2) using a nonrandomized pre-post design to examine whether individuals achieve clinically significant reductions in depressive symptoms.
