Eating disorder patients exhibit higher perceived external control and less assertiveness compared to healthy individuals. These traits, along with inwardly directed hostility, were also prevalent in psychiatric patients, suggesting shared psychological factors.

Area of Science:

  • Psychology
  • Psychiatry
  • Clinical Psychology

Background:

  • Anecdotal evidence suggests eating disorder patients feel controlled by family and society, yet lack assertive behaviors.
  • This perception warrants empirical investigation to understand the psychological underpinnings of eating disorders.

Purpose of the Study:

  • To compare assertiveness, locus of control, and family dynamics in patients with eating disorders versus control groups.
  • To investigate the prevalence of inwardly directed hostility and perceived family control in anorexia nervosa and bulimia nervosa.

Main Methods:

  • A comparative study involving female patients with anorexia nervosa and bulimia nervosa.
  • Inclusion of control groups: psychiatric patients, dieters, and non-dieting individuals.
  • Assessment using measures for eating disorder symptomatology, locus of control, assertiveness, hostility, and family dynamics.

Main Results:

  • Eating disorder patients reported significantly higher external locus of control compared to healthy controls.
  • Patients with eating disorders demonstrated lower self-assertion and less perceived family encouragement of independence.
  • No significant differences were found between eating disorder patients and psychiatric controls on most measures.

Conclusions:

  • Eating disorder patients share psychological characteristics, such as external control and low assertiveness, with other psychiatric patient groups.
  • Perceived external control and reduced assertiveness may be significant factors in the development or maintenance of eating disorders.
  • Findings suggest a potential overlap in psychological profiles between eating disorders and other psychiatric conditions.
