We assessed the cost of delivering COPE-CT from the Medicaid perspective and caregiver willingness-to-pay (WTP) for it. Program costs included interventionists’ time and travel, including home visits and communications, which were converted to $US2015 by multiplying hours spent by the appropriate wage, and applying the federal mileage reimbursement rate for travel. For WTP, 290 caregivers were read a brief description of COPE-CT at baseline (before randomization) and asked to estimate their per-session WTP using contingent valuation. Total time to deliver COPE-CT to the 130 dyads completing the program and available for analysis was 1,979 hours (1,665 OT, 314 RN), costing $122,520 ($103,913 OT, $18,607 RN), or $942/dyad. Baseline per-session WTP ranged from $0 to $200. 81 caregivers (27.9%) were unwilling to pay for this program, 74 (25.5%) willing to pay $10-25/session, 74 (25.5%) willing to pay $50-75/session, 41 (14.1%) willing to pay $100-125/session, and 20 (6.9%) willing to pay $150-200/session.
