Brief Summary:
The purpose of this study is to investigate areas of the brain responsible for self-regulation in adult women who have never had an eating disorder with women who have bulimia nervosa. More specifically, investigators are interested in changes in brain activation (e.g., changes in blood flow and oxygen use) when inhibiting responses and regulating emotions. Data collection will rely on a technology called functional magnetic resonance imaging (fMRI).

Outcome Measures

Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Self-Regulatory Control [ Time Frame: Day 2 (fMRI Scan) ]
    Functional Magnetic Resonance Imaging will be used to assess brain activation associated with motor inhibitory control and affect regulation in women with bulimia nervosa (BN)


Secondary Outcome Measures :
  1. Goal-Directed Action Control [ Time Frame: Day 1 ]
    An computerized instrumental learning task will be used to assess performance of women with and without bulimia nervosa.

  2. Eating Disorder Relevance [ Time Frame: Day 0 ]
    The Eating Disorder Examination (EDE) will be conducted to assess relative associations of motor, affective, and goal-directed action control with bulimia nervosa severity.
