Computerised CBT has shown promise as a way of offering treatment to people who are unable or unwilling to receive face-to-face treatment and for those in areas where it is difficult to travel to get treatment. It is also significantly cheaper than face-to-face therapy and could be a good way of delivering this service to more people. Researchers from the University of Bristol studied 297 people suffering from depression. Half of them used online CBT while the other half received 'care-as-usual' from their GP. After four months almost two-fifths of those who received the online CBT got better compared to one in four of those receiving treatment as usual. After eight months people were still feeling the benefits of the online CBT.
