Abbreviations: CBT, cognitive behavioural therapy; iCBT, internet-delivered CBT; ICER, incremental cost-effectiveness ratio; QALY, quality-adjusted life-year.
All costs in 2018 Canadian dollars. Costs and QALYs discounted at 1.5% rate.
Incremental cost = average cost (strategy of guided CBT followed by individual CBT) – average cost (strategy of guided CBT followed by group CBT).
Incremental effect = average effect (strategy of guided CBT followed by individual CBT) – average effect (strategy of guided CBT followed by group CBT).
