Dr. Jennifer Wildes provides an introduction to eating disorders, phenotypic heterogeneity, identifying homogeneous low-weight eating disorder phenotypes, mapping homogeneous phenotypes on to mechanisms, and implications for treatment.

Educational objectives:

Upon completion of this activity, participants should be able to:

  • Explain the importance of characterizing phenotypic heterogeneity (e.g., differing patterns of symptoms) in eating disorders.
  • Describe sources of phenotypic heterogeneity in eating disorders.
  • Discuss how variations in two forms of cognitive flexibility might help to explain phenotypic heterogeneity in eating disorders.
