Procedures

This study is registered on clinicaltrials.gov ({"type":"clinical-trial","attrs":{"text":"NCT03253601","term_id":"NCT03253601"}}NCT03253601) and all procedures were approved by the University of Pittsburgh Institutional Review Board (19040305). Participants provided written informed consent prior to initiating any research activities. The CONSORT checklist guided our design and reporting.

Upon admission to inpatient rehabilitation, medical records were reviewed to identify potentially eligible participants. We then approached potentially eligible participants to describe the study, obtain informed consent, and complete the full screening process to determine eligible participants. Eligible participants were randomized to receive strategy training using the mobile health platform or the traditional workbook after completing baseline testing and prior to initiating intervention procedures. Randomization was conducted using a computer-generated program with a 1:1 ratio blocked randomization (blocks of 4). Randomization was concealed from all study team members except for a research coordinator who was not involved with recruitment, screening, testing, or intervention procedures. Participants in both groups received seven in-person sessions of strategy training during inpatient rehabilitation in addition to their usual care. Following discharge home, participants received three monthly remote intervention sessions conducted over the phone. Between remote sessions, participants in both groups were encouraged to contact therapists with questions or concerns.
