Computer-aided psychotherapy: revolution or bubble?

Research into computer-aided psychotherapy is thriving around the world. Most of it concerns computer-aided cognitive–behavioural therapy (CCBT). A recent narrative review found 97 computer-aided psychotherapy systems from nine countries reported in 175 studies, of which 103 were randomised controlled trials. The rapid spread of the mass delivery of psychotherapy through CCBT, catalysed in the UK by the National Institute for Health and Clinical Excellence's recommendation of two CCBT programmes and the Department of Health's CCBT implementation guidance, seems unprecedented. This editorial is a synopsis of the current status of CCBT and its future directions.
