 Randomization Procedures Participants will be randomly assigned 1:1 to one of the two study arms n 59 per arm using a permuted block randomization procedure. Randomization will be stratified by principal diagnostic group and block size will be varied to minimize the likelihood of unmasking. After determining eligibility and completing consent and baseline assessment materials, enrolled participants will be assigned to treatment groups by the Project Research Assistant using a computer generated randomization scheme. Once a participant is randomized and attends the first session, they will be included in the intent-to-treat analysis. Randomization will occur at the participant level.
