Participant Flow
Participants were recruited by a letter from their primary care physician from three Department of Veterans Affairs Medical Centers and then screened by telephone by study staff between January 2019 and November 2022. The first participant was enrolled on February 8, 2019 and the last participant enrolled in November 2022.
A total of 283 participants were enrolled in the study and completed the baseline assessment. Of these, 83 did not meet eligibility criteria and 6 eligible participants withdrew prior to randomization. As a result, 194 participants were randomized.
