2. Prevalence of Co-Occurring Anxiety Disorders with Eating Disorders

  • Kaye et al. (2004) studied the co-morbidity of anxiety disorders in an eating disorder sample, and found the following:
  • Two-thirds of the subjects had one or more lifetime anxiety disorder
  • A majority of the subjects reported that their anxiety disorders preceded the onset of the eating disorder
  • The most common anxiety diagnoses were obsessive-compulsive disorder (OCD; 41%) and social phobia (20%)

3. Effects of a Co-Morbid Anxiety Disorder on Eating Disorder Symptomology

  • Clients with co-morbidity experience both a longer length of stay and an exacerbation of eating disorder symptoms such as:
  • Perfectionism
  • Obsessionality
  • Harm avoidance, including:
    • Higher degrees of worry, or anticipatory anxiety
    • Higher degrees of intolerance of uncertainty
    • Higher degrees of fatigue
    • Higher degrees of pessimism
  • Body image dissatisfaction
  • Higher scores on depression inventories

4. The Importance of Treating Co-Morbid Anxiety Disorders(Steinglass et al., 2010)

  • Studies report that individuals with anorexia nervosa endorse significantly higher levels of anxiety than healthy controls both while underweight and after weight restoration
  • Trait anxiety has been identified as a differentiating factor between patients who remitted from anorexia nervosa
    • Trait anxiety as measured by the State-Trait Anxiety Inventory (STAI; Speilberger)
  • Symptom substitution

5. Elements of Clinical Anxiety

  • Fear Cues:Stimuli and situations that elicit anxiety
  • Maladaptive Beliefs:Exaggerated estimates of threat
    • Catastrophizing
    • Probability Overestimation
  • Safety Behaviors: Actions intended to detect, avoid, or escape a negative or feared outcome (Abramowitz, 2011)

6. Elements of Clinical Anxiety

  • Safety Behaviors (continued; Abramowitz, 2011)
    • Passive avoidance
    • Checking and reassurance seeking
      • Checking locks, doors, outlets
      • Information seeking
      • Reassurance seeking
      • Visual checking
    • Compulsive rituals
      • Handwashing
      • Repetition of standing up, sitting down
      • Praying

7. Elements of Clinical Anxiety

  • Safety Behaviors(continued; Abramowitz, 2011)
    • Brief, covert (mini) rituals
    • Safety signals
      • Cell phone when leaving house
      • Anti-anxiety medication
      • Keys
      • Safe person

8. Eating Disorders as Obsessive-Compulsive Spectrum Disorders

  • Fear Cue: Fear of fat (Steinglass et al., 2010)
  • Maladaptive Beliefs:Irrational thoughts regarding food, weight, and shape; overestimation of the likelihood and consequences associated with the threat
  • Safety Behaviors:Passive avoidance, body checking, restriction, purging, compulsive exercise, calorie counting, food rituals

9. The Application of Anxiety Treatments to Eating Disorders

  • Outcome studies suggest that Exposure and Response Prevention Therapy (ERP) is an effective form of treatment for co-morbid eating and anxiety disorders:
  • Results indicate that CBT with a primary focus on ERP is a successful treatment approach for treating persons with both obsessive-compulsive disorder and an eating disorder. Significant changes in the severity of obsessive-compulsive symptoms, depressive symptoms, and eating disorder symptoms were noted(Adams, Riemann, Weltzin, & McGinty, 2007) .

10. Exposure and Response Prevention Therapy

  • Exposure
  • Graduated, repetitive, and consistent exposure to situations and thoughts that provoke anxiety and distress
    • Situational/In vivo exposure
    • Imaginal exposure
  • While performing the exposure, the client imagines the feared consequence(s) of the exposure
  • The client remains exposed to the cue until the associated anxiety decreases
  • Goal is to achieve habituation, or the decrease in anxiety due only to the passing of time
    • Within-trial habituation
    • Between-trial habituation

11. Exposure and Response Prevention Therapy 12. Exposure and Response Prevention Therapy

  • Response Prevention
  • Refraining from behaviors that are meant to reduce anxiety
    • Behavioral rituals
    • Mental rituals
    • Avoidance
  • Clients learn that feared consequences of exposure are irrational
  • Example:Eat a feared food such as potato chips( exposure ), no purging/binging/exercise/restriction ( response prevention ).

13. Fear Hierarchy Formation

  • Generate a list of external and internal triggers that provoke anxiety and induce urges to engage in behaviors
  • Assess feared consequences if client was exposed to a trigger
  • Assess responses to feared situations:
    • Passive avoidance
    • Behavioral rituals
    • Mental rituals
  • Generate a list of feared situations
  • Ask the client to provide a subjective unit of distress (SUDS) rating for each situation

14. Fear Hierarchy Formation

  • Examples of assignments to generate data:
  • Assign clients to create a list of the following:
    • Good/bad foods
    • Avoided foods
    • Binge foods
  • Assign clients to complete a an exhaustive list of their ritual behaviors at the table, and to identify what purpose these rituals serve
  • Assign clients to write A Typical Day
    • in my eating disorder.
    • in my exercise addiction.
    • in my OCD.

15. Fear Hierarchy Formation

  • Assign clients to write The Worst Day of My Eating Disorder
  • Assign clients to write out their exercise routine in exhaustive detail
