A clinician’s quick guide to evidence-based approaches: obsessive compulsive disorder (version 2)

The first edition of this guideline was published in 2014, shortly after the publication of the DSM-5, which had moved obsessive compulsive disorder (OCD) for the first time to being the central disorder within its own category, including disorders with similar phenomenology, such as body dysmorphic disorder, along with disorders with repetitive behaviours such as trichotillomania and skin-picking disorder. While much of the knowledge from the first edition remains current in terms of CBT as a frontline treatment, unsurprisingly this new edition also incorporates elements from the current zeitgeist of therapy more generally, including third wave approaches, advances in access to treatment, and other more recent developments.
