Anorexia Nervosa01:28

Anorexia Nervosa

Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.

Self-Discrepancy and Its Effects

252
Self-discrepancy theory explains how people compare their actual self to their ideal and ought selves and how mismatches between these self-guides can lead to emotional distress. Developed by E. Tory Higgins, the theory distinguishes among three components of self-concept: the actual self, the ideal self, and the ought self. These refer respectively to how individuals perceive themselves, how they aspire to be, and how they believe they are obligated to be. Emotional well-being, self-esteem,...

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Self-Regulation01:25

Self-Regulation

184
Self-regulation, also known as self-control, encompasses a range of cognitive and behavioral processes that allow individuals to adjust their internal states and outward actions to align with socially acceptable norms and long-term goals. It plays a fundamental role in adaptive functioning, from resisting impulsive behaviors to persisting through challenging tasks. While its benefits are widely recognized, self-regulation is not limitless. Muraven and Baumeister's theory posits that...

Bulimia Nervosa01:30

Bulimia Nervosa

619
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...

Introduction to Psychological Disorders

936
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...

Summary

Psychological inflexibility worsens disordered eating when internalizing thin ideals. Psychological flexibility does not offer protection, and acceptance may be harmful if focused on thinness.

Area of Science:

  • Psychology
  • Clinical Psychology
  • Eating Disorder Research

Background:

  • Internalizing thinness ideals is linked to disordered eating.
  • Protective factors against disordered eating are crucial for individuals internalizing thinness ideals.
  • Psychological flexibility and inflexibility are explored as potential moderators.

Purpose of the Study:

  • To investigate psychological flexibility and inflexibility as moderators in the relationship between thin-ideal internalization and disordered eating.
  • To identify specific components of psychological inflexibility that influence disordered eating.
  • To examine the role of acceptance in this context.

Main Methods:

  • College women (N=201) completed measures of psychological flexibility/inflexibility, thin-ideal internalization, and disordered eating.
  • Statistical analyses were used to examine moderation effects.

Main Results:

  • Psychological inflexibility significantly moderated the link between thin-ideal internalization and disordered eating.
  • Specific inflexibility components (Fusion, Lack of Present Moment Awareness, Lack of Values, Inaction) were significant moderators.
  • Contrary to hypotheses, acceptance was positively related to disordered eating.

Conclusions:

  • Psychological inflexibility exacerbates disordered eating risks associated with thin-ideal internalization.
  • Interventions may need to address specific inflexible processes rather than solely promoting acceptance.
  • Acceptance of thinness-related thoughts may be detrimental, highlighting the need for value-guided action.
