OCD
• DSM-V has reclassify under new grouping of Anxiety
  and Obsessive-Compulsive Spectrum Disorders.
  – Body Dysmorphic Disorder.
  – Hair-pulling Disorder.
• Characterized by either obsessions or compulsions.

Obsessions
• Recurrent, and persistent thoughts, urges, or images
  that are experienced as intrusive and unwanted and
  cause marked anxiety or distress.
• Person attempts suppress obsessions or to neutralize
  them with some other thought or action (i.e.,
  compulsion).

                                                                3	
  
Common Obsessions
• Contamination (1).
• Repeated doubt (2).
• Need for exactness or symmetry.
• Need to tell, ask or confess.
• Harming.
• Sexual imagery.
• Religious.

Compulsions
• Repetitive behaviors or mental acts that the person
  feels driven to perform in response to an obsession or
  according to rules that must be applied (i.e., ritual).
• Behaviors or mental acts are aimed at preventing or
  reducing anxiety or distress or preventing some
  dreaded event.

Assessment
• Yale-Brown Obsessive-Compulsive Scale (Y-BOCS;
  Goodman et al., 1989).
    – 60 symptom checklist (past and current).
       • Self-report version.
       • Childhood version (CY-BOCS).
    – 10 item severity rating scale (0-4).
       • 5 questions regarding obsessions.
       • 5 questions regarding compulsions.
       • Mean score for OCD = 24.

Y-BOCS
•    0- 7 = subclinical.
•    8-15 = mild.
• 16-23 = moderate (16 trial cut-off).
• 24-31 = severe.
• 32-40 = extreme.

ERP for OCD
• Key element to effective treatment for OCD.
  – Meyer (1966).
  – Based on the principle of habituation.
  – Habituation is the decrease in anxiety experienced with
    nothing but the passage of time.

Exposure and the Keys to Success
• Exposure is placing an individual in feared situations
  (targets the obsessions).
  – Needs to be prolonged enough to lead to within trial
    habituation (at least 50% reduction in anxiety).

Keys to Exposure
 – Needs to be repetitive enough to lead to between trial
   habituation (until causes minimal to no anxiety).
 – Treatment effect.

Keys to Exposure
 – Needs to be graduated (increases compliance).
   • Compliance with doing the exposures.
   • Compliance with doing the ritual prevention.

                                                                10	
  
 

Ritual Prevention
• Ritual Prevention is blocking the typical response or ritual
  before, during, and after exposure so habituation can take
  place (targets compulsions).

  – Replace the ritual with habituation as way of controlling anxiety.

Exposure Hierarchy Development
• Y-BOCS symptom checklist and severity rating scales.
• Generate specific exposure exercises.
• Patient rates each exercise on scale of 0-7 on
  perceived difficulty.
• Create exposure hierarchy.

                                                                                11	
  
Sample of Exercises
• 3’S
  – Touch bedroom door knob and don’t wash.
  – Turn on stove and turn off and don’t check.
  – Rotate couch pillow 15 degrees to left don’t fix.
  – Drive past high school at 9:30 a.m. don’t drive around block
    to check.

Outcomes
• American Psychiatric Association (2007) recognized
  ERP, SRI, or a combination as evidenced-based
  treatments for OCD.
• Foa et al. (1996) meta-analysis of 12 ERP studies with
  330 patients.
  – 83% much or very much improved.

                                                                   12	
  
Outcomes
• Greist et al. (1996) compared 18 studies with 294
  patients.
  – Average decrease in YBOCS of 11.8 with ERP (SRI’s=7.5).
• Foa et al (2005) multi-site study found:
  – CMI < ERP = ERP+CMI.
• ERP also effective for pediatric OCD (e.g., POTS
  Team, 2004).

Outcomes, con’t
• Low relapse rates with ERP.
  – Foa (1996) 16 studies with 376 patients found 76% much or
    very much improved at follow-up (average 2.5 years).

                                                                13	
  
Advantages of ERP
• Effective and robust.
• “Only” side effect is increased anxiety during treatment
  (can manage by conducting graduated exposure).
• Quick improvements (many after first week of treatment).

Disadvantages of ERP
• Hard work.
• Noncompliance.
• Absence of ERP.
• Quality of ERP when available.

                                                             14	
  
New Directions
• Attention Retraining.
  – Those with anxiety disorders have been found to exhibit an
    attention bias for disorder specific threat cues.
  – Computer program trains individuals to redirect their
    attention away from threat onto neutral cues thus correcting
    attention basis.
  – Leads to significant symptom reductions.

Attention Retraining
  – 6 randomized controlled trials.
  – Stand-alone treatment for generalized anxiety disorder,
    social anxiety disorder and chronic pain.
  – CBT enhancement for OCD.
     • Riemann, Kuckertz, Rozenman, Weersing & Amir (2013).
     • Enhanced outcome for OCD, social anxiety, and depression vs.
       placebo.

                                                                      15	
  
 

Summary
• OCD is a common and debilitating condition.
• Key element of effective treatment is ERP.
• Keys to effective exposure therapy include prolonged,
  repetitive and graduated exposure.
• Attention retraining may also prove to be effective in
  treating OCD stand-alone or as an augmentation to
  ERP.
