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...
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...

Psychosexual Stages of Personality: Oral01:16

Psychosexual Stages of Personality: Oral

The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.

Self-Discrepancy Theory02:45

Self-Discrepancy Theory

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.
Bullying02:04

Bullying

A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is bullying.

Area of Science:

  • Psychology
  • Public Health
  • Psychiatry

Background:

  • Subclinical eating disorders (ED) are common but understudied regarding age and gender.
  • Limited knowledge exists on symptom variations and psychosocial links.

Purpose of the Study:

  • Investigate age trends and gender differences in binge eating, purging, and compensatory behaviors (CB).
  • Examine the relationship between these behaviors and psychosocial problems.

Main Methods:

  • Utilized data from the "Young in Norway" longitudinal study (ages 14-34).
  • Employed statistical analyses including chi-squared tests, logistic random intercept models, and analyses of covariance.

Main Results:

  • Compensatory behaviors (CB) decreased with age in both genders.
  • Binge eating declined significantly over time only in females.
  • Females showed a higher risk for purging, which correlated with severe psychosocial issues like anxiety, depression, and low self-concept.

Conclusions:

  • Purging behaviors identify a high-risk group needing targeted intervention.
  • Severity differences among subclinical ED suggest potential reformulation of EDNOS in DSM-V.
