Reduction of Depression in People With Disabilities Through Dual Treatment: Digital CBT & NBHWC Coaching

The purpose of this study is to see if a mobile-delivered mental health program called Toivoa-002, which combines digital cognitive behavioral therapy (CBT) with personal mental health coaching, can effectively reduce depression in adults with hearing or mobility disabilities. The study aims to answer whether this dual-intervention digital service is more effective at lowering depression symptoms over an 8-week period than a "sham" digital program that is developed to look similar but does not contain active therapeutic content. The investigators hypothesize that participants who use the Toivoa-002 program will show significantly greater reductions in depression compared to those using the sham program, and that these mental health benefits will last through a 12-week follow-up. Adults within the disability community frequently encounter unique environmental and societal barriers - such as limited physical accessibility, transportation challenges, and workplace inflexibility - that can directly drive or worsen depression. By offering a fully remote and accessible mobile tool, this study seeks to determine if a digital health service can deliver scalable, effective depression relief tailored to the lived experiences of people with disabilities.
