Bulimia Nervosa01:30

Bulimia Nervosa

Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Binge Eating Disorders01:23

Binge Eating Disorders

Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...
Aggression01:47

Aggression

Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for hire...
Borderline Personality Disorder01:25

Borderline Personality Disorder

Borderline Personality Disorder is a complex and multifaceted mental health condition characterized by pervasive instability in interpersonal relationships, self-image, emotions, and impulse control. This instability manifests in extreme emotional reactions, fear of abandonment, and self-destructive behaviors. The disorder significantly impacts daily functioning, often leading to distress in both personal and professional domains.

Introduction to Psychological Disorders01:19

Introduction to Psychological Disorders

Abnormal behavior, often referred to as mental illness, results from changes in brain function that influence thought patterns, behaviors, and social interactions. Psychologists and psychiatrists typically assess abnormal behavior using three primary criteria: deviance, maladaptation, and personal distress, particularly when these traits persist over long periods.
Deviant Behavior
Deviance in behavior refers to actions or thought patterns that significantly diverge from societal norms or...

Area of Science:

  • Psychiatry
  • Clinical Psychology
  • Eating Disorder Research

Background:

  • Eating disorders (EDs) are associated with behavioral and cognitive aggression dimensions.
  • Empirical research on the relationship between aggression and EDs is limited.

Purpose of the Study:

  • To investigate the empirical relationship between aggression and eating disorders.
  • To compare aggression levels in patients with anorexia nervosa and bulimia nervosa against healthy controls.

Main Methods:

  • 112 female patients with anorexia nervosa (n=61) or bulimia nervosa (n=51) and 631 healthy female high school students (controls) completed self-report measures.
  • Instruments included the Eating Attitudes Test, Bulimic Investigatory Test of Edinburgh, Body Attitudes Test, and Buss-Perry Aggression Questionnaire (AQ).

Main Results:

  • Eating disorder symptom scores positively correlated with aggression questionnaire scores in both patients and controls.
  • Anorexia nervosa patients scored lower on physical and verbal aggression than controls.
  • Bulimia nervosa patients scored higher on anger than controls, but similar on other aggression facets.

Conclusions:

  • Patients with bulimia nervosa exhibit a higher propensity for anger.
  • Anorexia nervosa may involve difficulties in anger expression and outward-directed aggression.
  • Potential confounding factors include the younger age of controls and reliance on self-report data.
