ERP exposes the patient to the obsessional trigger and prevents the compulsive response. The patient learns through HABITUATION that anxiety naturally decreases on its own without performing the compulsion. Statement 1 (replacing thoughts) is not how ERP works — it is acceptance + non-engagement, not thought replacement. Statement 3 (medication to dampen anxiety) UNDERMINES exposure because the patient never learns the anxiety self-resolves. Statement 4 (avoid all triggers) is the opposite of ERP — between-session avoidance prevents generalization.
In-depth explanation
The therapeutic mechanism of ERP is the anxiety habituation curve: anxiety spikes during exposure, peaks within 30-60 minutes, and falls naturally if the compulsion is not performed. Each repeat exposure produces a faster, lower curve. Anything that short-circuits the curve (PRN benzo, mental rituals, reassurance-seeking) blocks therapy progress.
