I have no conflicts of interest to discloseSlide3

Eating Disorders And obsessive Compulsive DisorderEating disorders (EDs) and obsessive-compulsive disorder (OCD) are highly comorbid

Which comes first?

Is it possible that these symptoms are interrelated?

Pallister & Waller, 2008Slide4

Network AnalysisNetwork analysis allows us to identify:

How symptoms of comorbid disorders are associated with each other

Bridge symptoms, which may explain how symptoms of one disorder are connected to symptoms of another disorder

, & Craver, 2011Slide5

Possible Bridge Symptoms: Perfectionistic thoughts & Behaviors

Perfectionism is highly related to eating disorders

Maintenance and developmental factor

Perfectionism is also highly related to OCD

Perfectionism OCD

Perfectionistic cognitions and behaviors may be a bridge between eating disorder and OCD symptoms

Bardone

-Cone et al., 2007; Lee et al., 2009Slide6

Current Study

What symptoms are central in an OCD & ED symptom network?

Does perfectionistic thoughts and behaviors bridge between OCD and ED symptoms?

Does an OCD & ED symptom network remain similar across one month?Slide7

Participants

Participants are 168 individuals diagnosed with an eating disorder

Primarily anorexia nervosa (n = 120; 71.4%)

Currently in treatment (n = 117; 69.6%)

Diagnosed with OCD (n = 24; 14.3%)

Average age = 26.3 (SD = 9.44)

Primarily female (n = 159; 94.6%)

Primarily European American (n = 156; 92.9%)Slide8

PROCEDUREParticipants recruited from eating disorder clinic after discharge

Completed the Obsessive Compulsive Inventory, Eating Disorder Inventory-II, & the Frost Multidimensional Perfectionism Scale

One month later completed these measures again

Time 1 OCD/ED: Centrality

OCD

I am upset by unpleasant thoughts that come into my mind against my will

I find it difficult to control my own

thoughts

ED

I am terrified of gaining weight

I think my thighs, buttocks are too large

OCD symptoms more central than ED symptomsSlide12

What about Perfectionism?Slide13
Slide14

OCD, ED, & Perfectionism CentralityIf I do not do well all the time, people will not respect me (

The fewer mistakes I make, the more people will like me (

Time 2: OCD & ED networkDo these networks remain the same across time?Slide16
Slide17

Time 2 CentralityOCD

I am upset by unpleasant thoughts that come into my mind against my will

I have saved up so many things that they get in the way

ED

I am terrified of gaining weight

I think my buttocks are too large

I eat or drink in secrecy Slide18

ConclusionsOCD and ED cluster into two separate symptom networks

OCD symptoms are overall most central

Specifically, symptoms associated with difficulty controlling thoughts & having unwanted thoughts

Consistent with literature on eating disorder thoughts

Perfectionistic behaviors and thoughts cluster in between OCD and EDs

Most central items are related to social judgments on being imperfect

Networks are similar across one month with some minor differences

Bardone-Cone et al., 2007;

Bulik

et al., 2003Slide19

LimitationsInherent limitations with network analysis

No fit indices

Relatively small sample

Limited measurement of OCD and EDSlide20

IMPLICATIONSPerhaps treatments of comorbid OCD/ED should be tailored to focus on negative or uncontrollable thoughts

Mindfulness/acceptance therapies?

Perfectionism could be a target that reduces symptoms of both OCD and ED

CBT for perfectionism reduces anxiety, depression, and eating disorder symptomsSlide21
