Red flags

  • Calling 'ERP' what is actually exposure with rituals allowed, therapist reassurance, or endless psychoeducation without behavioural practice
  • Declaring ERP failed after inadequate dose, no between-session homework, or family accommodation left intact
  • Using prn benzodiazepines to blunt every exposure — may impair new learning
  • Starting high-intensity exposure during unmanaged suicide crisis, mania, or incapacity without stabilisation
  • Colluding with family accommodation (reassurance, checking for the patient) while claiming to treat OCD
  • Skipping ERP because an SSRI was started, or stopping indicated SSRI solely because ERP began

The one-line answer

Exposure and response prevention (ERP, or EX/RP) is the first-line behavioural psychotherapy for OCD: the patient confronts the obsession-evoking cue and blocks every compulsion — overt and mental — so the threatened catastrophe is put to the test and the prediction is disconfirmed. Foa showed EX/RP beats clomipramine alone; Simpson showed EX/RP beats risperidone and beats stress management as SRI augmentation; POTS showed CBT with ERP works in children. Half the name is response prevention — exposure without it is not ERP.[1][2][3][6]

Meet the patient

A 28-year-old nurse has spent four years hiding her cracked, bleeding hands from colleagues. She washes for forty minutes after every patient contact, sanitises her phone six times a shift, and asks her partner whether her hands are clean until he gives the answer that lets her stop. Her Y-BOCS is 28. Clomipramine took the edge off; the rituals did not move.[1][14]

The registrar's referral reads "OCD, refractory, consider augmentation." The examiner's question is sharper: what was the actual behavioural treatment she received, and was it ever ERP? Nine times in ten the answer is no — and that is the whole topic.[13][15]
