Body image distortion in bulimia nervosa.
Summary
Women with bulimia nervosa often misperceive their body size, overestimating body widths. Treatment significantly reduced this body image distortion, particularly for waist and hip measurements.
Area of Science:
- Psychology
- Psychiatry
- Body Image Research
Background:
- Body image disturbances are common in eating disorders.
- Accurate body size perception is crucial for psychological well-being.
Purpose of the Study:
- To investigate body image perception in women with bulimia nervosa compared to controls.
- To explore factors influencing body size overestimation in bulimia nervosa.
- To assess the impact of treatment on body image perception.
Main Methods:
- Utilized a visual size estimation apparatus to measure body width perception.
- Compared 50 women with bulimia nervosa to 19 age- and weight-matched female controls.
- Assessed changes in body image perception following a 10-session outpatient treatment program.
Main Results:
- Both groups overestimated body widths, but not neutral object widths.
- A trend suggested bulimics overestimated more than controls, though not significantly.
- Bulimics with a higher weight index and those heavier than matched controls showed greater overestimation.
- Treatment led to a significant decrease in overestimation of waist and hip width.
Conclusions:
- Women with bulimia nervosa exhibit altered body size perception, overestimating body widths.
- Body weight and dissatisfaction appear linked to the degree of body size overestimation.
- Outpatient treatment can effectively improve body image perception in individuals with bulimia nervosa.
