A brief online intervention significantly improved body image satisfaction and motivation to change body image in individuals seeking eating disorder information on social media. This micro-intervention offers a promising approach to address body image concerns.
Area of Science:
- Psychology
- Digital Health
- Eating Disorder Research
Background:
- Young individuals at risk for eating disorders often use social media and search for body image-related content.
- Previous research demonstrated a guided chat-based intervention's effectiveness in reducing eating disorder pathology.
Purpose of the Study:
- To assess if a modified single-session mini-course could reduce body image concerns.
- To evaluate the intervention's impact on individuals searching for eating disorder-related terms on social media.
Main Methods:
- A web-based mini-course was developed from a prior chat-based intervention.
- 525 individuals accessed and completed the mini-course via a social media prompt over two months.
Main Results:
- Significant improvement in body image satisfaction (p < .001, Cohen's d = 0.54).
- Significant increase in motivation to change body image (p < .001, Cohen's d = 0.28).
- Participants reported the program was enjoyable and easy to use.
Conclusions:
- A single-session micro-intervention delivered via social media can effectively improve body image.
- This approach shows potential for early intervention among at-risk individuals.
- Digital interventions offer accessible avenues for addressing body image concerns.
