Cognitive-Behavioural Model of BDD
Veale (2004) · Body dysmorphic disorder
Written by Tarun Vermani, Trainee Clinical Psychologist Last reviewed
Veale's cognitive-behavioural model of body dysmorphic disorder (2004) explains preoccupation with a perceived flaw as a distorted, observer-perspective image of the feature, held against exacting appearance standards and maintained by checking, comparing and concealment.
Cognitive-Behavioural Model of BDD
Veale (2004)
Trigger
A trigger that brings appearance to mind — catching sight of yourself in a mirror or reflection, a photo, a comment, or entering a situation where you feel looked at.
Negative Image & Beliefs
A distorted mental image of the feature, viewed from an observer's perspective, with attention zooming in on the perceived defect. Processed against exacting internalised standards about appearance and its importance — 'my nose is huge and deformed', 'if I look flawed I'm worthless and will be rejected'.
Distress
Painful emotions — shame, disgust, anxiety and low mood — driven by the appraisal of the feature and what it is taken to mean about the self.
Rumination / Checking
Self-focused attention, rumination and checking — mirror gazing, comparing the feature with other people's, mentally going over it, and seeking reassurance. Checking and comparing amplify the distortion and keep the feature salient.
Avoidance / Concealment
Safety behaviours, concealment and avoidance — camouflage with make-up, hair, clothing or posture, grooming rituals, skin picking, pursuit of cosmetic procedures, and avoiding mirrors, photos or social situations. These prevent disconfirmation and maintain preoccupation and distress.

Understanding the model
Most of us have parts of our appearance we'd change, but in body dysmorphic disorder (BDD) a perceived flaw takes over — it feels glaringly obvious and deeply distressing, even when others can't see a problem. This model shows how BDD keeps itself going.
A trigger — often a mirror, a photo, or a comment — brings appearance to mind. Up comes a distorted internal picture of the feature, seen as if through someone else's eyes, with attention zooming in on the part that feels wrong. Held up against very high standards for how you 'should' look, it seems ugly or abnormal.
That brings painful feelings — shame, disgust, anxiety, low mood — and a strong pull to do something about it.
So people check mirrors, compare themselves with others, go over the flaw in their mind, and try to hide or fix it with make-up, grooming, clothing or procedures, while avoiding situations where they feel exposed. These responses ease the distress briefly but keep attention locked on the feature, strengthen the distorted image, and stop you finding out that others aren't reacting as you fear — so the preoccupation continues.
Questions therapists ask about this model.
Frequently asked questions
What maintains BDD according to this model?
A trigger such as a mirror, a photograph or a comment brings appearance to mind and calls up an internal picture of the feature, seen as if through someone else's eyes, with attention zoomed in on the part that feels wrong. Measured against very high standards it looks abnormal, bringing shame, disgust, anxiety and low mood. Mirror checking, comparing, concealment and avoidance then ease the distress briefly while keeping attention locked on the feature.
How does it differ from the OCD model?
Both describe checking, comparing and reassurance-seeking, and NICE CG31 covers both presentations. In Salkovskis's OCD model (1985) the driver is the meaning given to an intrusive thought, usually responsibility for preventing harm. Here the driver is the distorted image of a specific feature, and what the client takes their appearance to say about their worth and about how others will treat them.
How did the BDD model develop?
Veale and colleagues (1996) first set out a cognitive-behavioural model of body dysmorphic disorder. Veale (2004) extended it, giving a central place to the distorted, observer-perspective image of the feature, to attention that zooms in on it, and to how much appearance matters to the client's sense of self. Wilhelm, Phillips and Steketee (2013) describe a related cognitive-behavioural approach to body dysmorphic disorder, so clinicians may meet overlapping terms in both.
