The potential of telemental health applications for obsessive–compulsive disorder

BackgroundOnly a small percentage of patients with obsessive-compulsive disorder (OCD) receive adequate treatment. Reasons include a high level of shame and stigmatisation and the paucity of specialised treatment services. Telemental health (TMH) treatment could improve the therapeutic situation as has been shown for various mental disorders. This review critically evaluates the current body of evidence on TMH applications for OCD patients. The review focuses on studies that include exposure therapy with response prevention as the best validated treatment component.MethodsRelevant publications were identified through computerised searches of the databases PsycINFO and PubMed and manual searches. No date or study type restrictions were applied.ResultsTwenty-four studies on different types of TMH applications were identified: bibliotherapy (7), telephone-delivered (11), computer-aided (3), online self-help group (1) and video-conference (2). Nearly all interventions lead to a significant improvement of OC symptoms. Effect sizes ranged from 0.46 to 2.5.ConclusionsPreliminary evidence suggests that TMH applications represent a low-threshold, efficacious, time-effective and economic treatment for patients with OCD. Future studies are needed to further investigate the potential of TMH treatment to improve health care for patients with OCD.

► Preliminary evidence suggests that telemental health applications provide an effective treatment for OCD.
► Future studies are necessary to determine the components critical to the treatment outcome.
► Studies on manual-based writing therapy, effective in other disorders, are required.
