Summary

Individuals with bulimia nervosa demonstrate higher hypnotizability compared to control groups. This increased susceptibility to hypnosis is linked to their dissociative tendencies, not response patterns.

Area of Science:

  • Psychology
  • Psychiatry
  • Eating Disorders

Background:

  • Bulimia nervosa is often associated with increased hypnotizability and dissociation.
  • Previous research suggests bulimic individuals differ from control groups and those with other eating disorders in these aspects.

Purpose of the Study:

  • To compare hypnotic susceptibility in patients with bulimia nervosa versus a control group.
  • To investigate the role of dissociation in the hypnotizability of bulimic individuals.

Main Methods:

  • A comparison between 15 inpatients with bulimia nervosa (DSM III-R) and 15 age- and education-matched controls.
  • Utilized the Harvard Group Scale of Hypnotic Susceptibility/Form A (HSGHS:A) with 12 standardized suggestions.

Main Results:

Related Experiment Videos

  • Bulimic patients exhibited significantly higher hypnotizability scores than the control group.
  • A methodological analysis confirmed that observed behavior, not response bias, accounted for the higher scores.

Conclusions:

  • Bulimia nervosa patients show enhanced hypnotizability, likely related to their dissociative capacity.
  • The increased dissociation may be a causal factor or an accompanying feature of bulimia nervosa.
