- sessions can last over 90 minutes with 15-20 sessions within 3 weeks
the success rate of exposure and response preventiong
the treatment is at least partially effective for more the 50% of OCD clients

therapised-guided exposure is better than therapist-assisted self-guided exposure and invivo combined
exposure via imagination is superior to exposure in vivo alone
cognitive approach to OCD treatment
- effectiveness
CBT –> need exposure and reponse prevention
- focus on clients convictio that imaginary events may actuall come true
- CBT effectiveness –> looks better than pharmacological treatment
exercise for OCD?
