Evidence about the cost-effectiveness and cost utility of computerised cognitive–behavioural therapy (CCBT) is still limited. Recently, we compared the clinical effectiveness of unsupported, online CCBT with treatment as usual (TAU) and a combination of CCBT and TAU (CCBT plus TAU) for depression. The study is registered at the Netherlands Trial Register, part of the Dutch Cochrane Centre (ISRCTN47481236).


To assess the cost-effectiveness of CCBT compared with TAU and CCBT plus TAU.


Costs, depression severity and quality of life were measured for 12 months. Cost-effectiveness and cost-utility analyses were performed from a societal perspective. Uncertainty was dealt with by bootstrap replications and sensitivity analyses.


Costs were lowest for the CCBT group. There are no significant group differences in effectiveness or quality of life. Cost-utility and cost-effectiveness analyses tend to be in favour of CCBT.


On balance, CCBT constitutes the most efficient treatment strategy, although all treatments showed low adherence rates and modest improvements in depression and quality of life.
