How to evaluate the relationship between body dissatisfaction and eating disorders?

Most welcome.

Thank you.

Evaluating the relationship between body dissatisfaction and eating disorders involves:
1. Standardized assessment tools: Use validated scales (e.g., Body Shape Questionnaire, Eating Disorder Examination Questionnaire) to measure body dissatisfaction intensity and disordered eating behaviors (restriction, bingeing, purging).
2. Longitudinal correlational analysis: Track how baseline body dissatisfaction predicts the onset or escalation of eating disorder symptoms over months/years, controlling for genetic predispositions or cultural influences.
3. Experimental manipulation studies: Induce temporary body dissatisfaction (e.g., via social media exposure) and observe acute changes in eating behaviors (e.g., food intake, body checking), comparing responses across high/low baseline dissatisfaction groups.
