 Depression is common and disabling but access to specialist treatment is often delayed with waiting lists of up to a year not uncommon. Also treatment is frequently limited to drug therapies because of long waiting lists to see psychological therapists face to face despite recommendations by NICE The National Institute for Health and Clinical Excellence and others about the importance of non-drug therapies. One way to address this problem is to use computerized e-therapies which deliver structured cognitive behavioral treatment where the therapy can be accessed in a location and at a time that is convenient for patients and where there is no waiting list. Previous randomized controlled trials of e-therapies for depression have mainly been in people recruited through the internet or in clinical populations with mild disorders where many participants do not complete the on-line course. Despite this there is some evidence that clinician-assisted computerized cognitive behavior therapy can result in significant improvements in depression with reduced demands on clinician time. To date there have been no trials of clinician assisted e-therapy in secondary care.
