This is a treatment development trial. Participants will be randomized to receive either XR-behavioral activation with a mobile app companion, XR-behavioral activation without a mobile app companion, behavioral activation as usual with a mobile app companion, or behavioral activation as usual without a mobile app companion. All groups will follow a BA protocol developed for primary care settings over a four-week treatment period.
The primary aims of this study are to assess the feasibility, acceptability, and tolerability of an extended reality (XR) behavioral activation (BA) treatment with and without a mobile app companion for individuals diagnosed with major depressive disorder (MDD). The secondary aim of this study is to explore the efficacy of using XR with and without a mobile app companion to deliver BA therapy to a clinical MDD population, as well as to explore the efficacy of traditional BA with a mobile app companion.
