Dissociative and hypnotic experiences in eating disorder patients: an exploratory study

Area of Science:

• Psychology
• Psychiatry
• Clinical Psychology

Background:

• Eating disorders are complex mental health conditions.
• Dissociation and hypnotizability are psychological phenomena that may be relevant to eating disorders.
• Previous research has explored these links, but further investigation is warranted.

Purpose of the Study:

• To explore the relationship between hypnotizability, subjective experiences during hypnosis, and dissociation in individuals with eating disorders.
• To compare these measures between eating disorder patients and a control group.
• To examine differences in dissociation and hypnotizability among subtypes of eating disorders.

Main Methods:

• A study involving 53 eating disorder patients.
• Assessment of dissociation using the Dissociation-Questionnaire (DIS-Q).
• Measurement of hypnotizability with the Stanford Hypnotic Clinical Scale (SHCS), subjective experiences with the Dutch Phenomenology of Consciousness Inventory (DPCI), and resistance to hypnosis with the Dutch Resistance to Hypnosis Scale (DRHS).

Main Results:

• Eating disorder patients scored significantly higher on dissociation (DIS-Q) and hypnotizability (SHCS) compared to controls.
• Bulimic and mixed-type anorexic patients reported higher scores on DIS-Q and SHCS than restricting anorexics, with a significant difference noted for DIS-Q's loss of control subscale.
• Positive correlations were observed between DIS-Q and SHCS, but their moderate strength suggests they measure distinct constructs.

Conclusions:

• Eating disorder patients demonstrate elevated levels of both dissociation and hypnotizability.
• Dissociation, particularly loss of control, may differentiate subtypes of anorexia nervosa and bulimia nervosa.
• While correlated, hypnotizability and dissociation appear to represent separate psychological constructs in the context of eating disorders.
