Compulsive behaviours — repetitive actions performed despite a desire to stop, often in response to anxiety, intrusive thoughts or emotional distress — significantly affect quality of life and can be debilitating when severe. They are central features of OCD but also occur in BDD, hoarding disorder, skin picking, hair pulling and other presentations. Specialist psychological therapy, particularly ERP-based CBT, produces reliable and often significant improvement.
Compulsive behaviour involves repetitive actions that are performed to reduce anxiety or distress, or in response to obsessional thoughts, urges or rigid rules. The relief is temporary — anxiety returns, driving further compulsion in a self-maintaining cycle. Compulsions can be behavioural (checking, washing, ordering, touching) or mental (reviewing, reassuring oneself, neutralising thoughts).
While compulsions are the defining feature of OCD, they also feature in body dysmorphic disorder (reassurance-seeking, checking), hoarding disorder, trichotillomania (hair pulling), dermatillomania (skin picking), and as features of anxiety disorders more broadly.
Compulsive behaviours may present as:
Compulsive behaviours respond well to specific psychological approaches:
OCD Action, OCD UK and the BDD Foundation can help find appropriate specialist therapists. It is important to work with a therapist trained specifically in ERP — general CBT without the ERP component is significantly less effective for compulsive presentations. NHS specialist OCD services exist in most regions.
We don't currently have any therapies mapped to this condition.
No — OCD takes many forms. Common themes include contamination fears, harm OCD (fear of harming self or others), pure O (intrusive thoughts without visible compulsions), relationship OCD, scrupulosity (religious or moral obsessions), and symmetry or ordering. Compulsions can be visible behaviours or entirely mental rituals.
Compulsions relieve anxiety rapidly and reliably, making them powerfully reinforcing even when unwanted. Willpower alone attempts to suppress behaviour without addressing the anxiety-relief cycle maintaining it. ERP specifically addresses this cycle by allowing anxiety to arise and naturally reduce without the compulsion — the mechanism through which lasting change occurs.
Exposure and Response Prevention (ERP) involves systematically facing feared triggers while refraining from the compulsive response. This allows the anxiety associated with the trigger to naturally reduce (habituation) and teaches the brain that the feared consequence does not materialise without the compulsion. It is the most evidence-based treatment for OCD and related presentations.
No — mental compulsions (reviewing events for reassurance, mentally neutralising thoughts, reassuring oneself) are common and often unrecognised. People with predominantly mental compulsions may believe they have 'pure O' (obsessions without compulsions) when in fact the compulsions are internal. ERP can target mental compulsions as well as behavioural ones.
Yes — SSRIs (selective serotonin reuptake inhibitors) have good evidence for OCD and are often used alongside ERP-based CBT. Combined treatment produces better outcomes than either alone in many cases. Medication decisions should be made with a GP or psychiatrist.
