New-wave behavioral therapies in obsessive-compulsive disorder: Moving toward integrated behavioral therapies.

New-wave behavioral therapies in obsessive-compulsive disorders (OCDs) comprise of third-wave therapies and newer cognitive therapies (CTs). This review covers outcome studies published in English until December 2017. A total of forty articles on mindfulness-based CT, metacognitive therapy, acceptance and commitment therapy, and danger ideation reduction therapy in the form of single-case studies, case series, open-label trials, two-group comparison studies, and randomized controlled studies were included. Results show that studies on these therapies are limited in number. Methodological limitations including lack of active control groups, randomized controlled trials, small sample sizes, and short follow-up periods were also noted. However, the available literature demonstrates the feasibility and utility of these therapies in addressing the issues unresolved by exposure and response prevention (ERP) and cognitive behavior therapy (CBT). These therapies were often combined with traditional ERP and CBT based on the profile and response of the client; hence, it is unclear whether they can be used as standalone therapies in the larger segment of the OCD population. Supplementary use of these strategies alongside established therapies could provide better utilization of resources. In view of the need for such integration, further research is warranted. The use of sound methodologies and establishing the mechanism of action of these therapies would assist in choosing the techniques for integration.
