Bulimia Nervosa01:30

Bulimia Nervosa

These behaviors create a cycle that temporarily lowers stress levels but can result in severe long-term health consequences. Breaking these habits is essential to reduce the risk of chronic diseases and improve overall well-being. Three primary changes that support better health include quitting smoking, reducing alcohol intake,...

Introduction to Psychological Disorders

245
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...

Depressive Disorders: Etiology01:27

Depressive Disorders: Etiology

55
Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
Biological Factors in Depression
Biological predispositions significantly influence the risk of developing depressive disorders. Genetic studies highlight the role of variations in the serotonin transporter...

Area of Science:

  • Psychiatry
  • Clinical Psychology
  • Public Health

Background:

  • Maladaptive eating behaviors are common in the US, particularly among college students.
  • Eating disorders (EDs) have high mortality rates and are linked to increased suicide risk, even at subclinical levels.

Purpose of the Study:

  • To examine the associations between specific problematic eating behaviors and suicide-related constructs and behaviors.
  • To investigate the relationship between dimensional measures of eating behaviors and overall suicide risk.

Main Methods:

  • 188 college students (62% women) completed the Eating Disorder Examination-Questionnaire and measures of suicidality.
  • A semistructured clinical interview was used to categorize suicide risk.

Main Results:

  • Moderate to strong associations were found between eating disorder examination questionnaire scores and suicide constructs.
  • Purging behavior showed the highest correlation with overall suicide risk (ρ=0.36).

Conclusions:

  • Findings support the interpersonal-psychological theory of suicide.
  • Results highlight practical implications for developing targeted interventions for at-risk individuals.
