Intrusive Thoughts – Moralistic and Relationship OCD – CBT treatment
Did you know that a study in 1992 by the highly esteemed psychologists Christine Purdon and David Clark (Purdon and Clark, 1992) found that 22% of men, without a diagnosed mental health condition, have thoughts of fatally pushing a friend? Women were shown not to fair a little better (9%…). But, still, 1 in 11 women or 1 in 5 men, do not find themselves acting on these thoughts.
Intrusive thoughts can be profoundly unsettling, not because of their content but because of the meaning people attach to them. When a distressing idea appears suddenly and without invitation, it’s easy to assume it reveals something important—about your morality, your intentions, or your relationships. For people experiencing moralistic OCD or relationship OCD, this interpretation becomes the engine of anxiety. Cognitive Behavioural Therapy (CBT) offers a way of stepping back from these interpretations and understanding intrusive thoughts are just part of the mind’s natural activity rather than evidence of danger or personal failure.
CBT treatment often starts with psychoeducation. Many people feel isolated by their intrusive thoughts, convinced that no one else could possibly think the things they do. Learning that intrusive thoughts are normal and universal—and that their presence says nothing about character—can be quietly transformative for many of the clients I see. In moralistic OCD, thoughts often centre on fears of being harmful or immoral. In relationship OCD, they may revolve around doubts about compatibility, attraction, or commitment. CBT helps people recognise that these thoughts are not moral verdicts or relationship assessments; they are simply mental events. However, naturally it can be tricky to determine what are our actual beliefs and what are intrusive thoughts.
Given this, CBT encourages a shift in how thoughts are interpreted. Cognitive restructuring invites people to examine the assumptions that give intrusive thoughts their power. Someone might ask themselves: “What am I assuming this thought means?” or “What evidence supports the conclusion I’m drawing?” This process isn’t about arguing with the thought but about loosening the grip of rigid interpretations. Over time, individuals begin to see the thought as uncomfortable rather than meaningful.
Exposure and Response Prevention (ERP) builds on this foundation. ERP involves allowing the intrusive thought to be present without engaging in the usual mental rituals—checking, analysing, seeking reassurance, or trying to “solve” the discomfort. For moralistic OCD, this might mean asking a client to notice a distressing thought without launching into moral self‑examination. For relationship OCD, it might involve sitting with uncertainty about feelings without testing the relationship or mentally reviewing past interactions. ERP helps the mind learn that discomfort can rise and fall naturally, and that intrusive thoughts lose their intensity when they are not fed by compulsive responses.
CBT treatment often also involves behavioural experiments. Behavioural experiments offer another gentle but powerful intervention. These experiments test the predictions that intrusive thoughts often carry. For example, with someone with moralistic OCD I might ask them to see if they can allow a thought to pass without neutralising it and observe that nothing dangerous happens. Someone with relationship OCD might be asked to spend time with their partner while allowing uncertainty to exist, noticing that connection can still emerge even when doubt is present. These experiences help build a more flexible, compassionate understanding of the mind.
Finally, CBT encourages a return to values. Intrusive thoughts often pull people into avoidance, rumination, or self‑monitoring. Values‑based action redirects attention toward what matters—kindness, curiosity, connection, integrity. When behaviour is guided by values rather than fear, intrusive thoughts begin to feel less central and less authoritative.
CBT does not aim to eliminate intrusive thoughts; instead, it helps people relate to them differently. In doing so, it opens space for a life that feels more grounded, more intentional, and less governed by the noise of the mind.
