Study Overview

  • Title: A Comparison of Eating Disorders and Body Dysmorphic Disorder on Body Image and Psychological Adjustment.

  • Authors: James C. Rosen and Elena Ramirez.

  • Publication: Journal of Psychosomatic Research.

  • Date: 1998.

  • Objective: To compare body image disturbance and psychological adjustment in eating disorders and body dysmorphic disorder (BDD).

Research Background

  • Eating disorders and body dysmorphic disorders are characterized by body image disturbances.

  • Limited prior research on the similarities and differences between these two disorders.

  • Importance of clarifying the relationship could enhance understanding of body image and psychopathology.

Methodology

  • Participants:

    • 45 women with anorexia or bulimia nervosa.

    • 51 individuals diagnosed with body dysmorphic disorder (BDD).

    • 50 nonclinical controls.

  • Assessment Tools:

    • Eating Disorder Examination: Utilized for diagnosis of anorexia nervosa and bulimia nervosa.

    • Body Dysmorphic Disorder Examination (BDDE): For diagnosing BDD and measuring symptoms.

    • Brief Symptom Inventory: To assess psychological symptoms.

    • Rosenberg Self-Esteem Scale: To gauge self-esteem levels.

Key Findings

  • General Observations:

    • Both disorders display severe body image symptoms and negative self-esteem compared to controls.

    • Eating disorder patients showed more widespread psychological symptoms.

Body Image Disturbance

  • Eating disorder patients concentrated on weight and body shape.

  • BDD subjects reported a variety of physical complaints and higher negative self-evaluation associated with appearance.

Psychological Symptoms

  • Eating disorder patients exhibited more significant psychological distress than BDD patients based on the Brief Symptom Inventory.

  • BDD patients reported more avoidance due to self-consciousness about appearance and negative self-evaluation linked to appearance.

Appearance Concerns

  • Area of Concern Distribution:

    • Eating disorders predominantly focused on lower body areas.

    • BDD concerns were more diverse, including skin imperfections and facial features.

Discussion

  • Comparison of Disorders:

    • Although there are differences in the locations of perceived defects, both disorders demonstrate high levels of body dissatisfaction and preoccupation with appearance.

    • Eating disorders might involve greater psychological maladjustment, partly due to self-blame for body image issues, which is less common in BDD due to inherited features.

  • Social Functioning Impacts:

    • BDD is significantly distressing with social functioning impairments linked to high avoidance behavior.

Conclusions and Future Research

  • Conclusion:

    • Eating disorders and BDD share comparable psychological features despite differences in symptom focus and severity of psychological distress.

  • Recommendations for Future Studies:

    • Need for further empirical research to explore the overlaps and distinctions between these disorders.

    • Investigating cognitive abnormalities and their relations within the context of each disorder could provide insights into their pathology.
