A cohort of 63 Veterans Affairs (VA) mental health providers delivered CBT-I to 180 veterans as part of an evidence-based psychotherapy trainingprogram and captured de-identified treatment outcome data through a data portal.

We tested the noninferiority of telehealth only compared with at least 1 in-person session
