SMS Messaging to Reduce Depression and Anxiety Following TBI

Control condition in which participants receive a single session with education on the importance of self-confidence and motivation, followed by 8 weeks of daily SMS messages with self-selected motivational statements.

Implementation intentions are created collaboratively by participants and therapists in a single 2-hour session that uses principles of brief BA (the planning of rewarding activities). BA-based implementation intentions will then be delivered daily by text for 8 weeks.

Participants undergo a total of 8 sessions with a therapist. During these sessions, participants learn about the principles of BA (the translation of important life values into the planning of rewarding activities that support those values). The participants' values are explored and an activity schedule is created collaboratively by participants and therapists based on those values. Reminders to complete the scheduled activities will then be delivered by text once the schedule is made. Participants in this arm will also be monitoring their daily activities (and rating them based on enjoyment and perceived achievement) using a cell phone application.
