A randomized controlled trial of a reading-based weight bias intervention

Area of Science:

• Psychology
• Public Health
• Behavioral Science

Background:

• Weight bias, negative attitudes towards larger bodies, is widespread and linked to adverse health outcomes and discrimination.
• Existing interventions to reduce weight bias show mixed results.
• Combining interventions targeting weight controllability beliefs, stereotypes, and empathy may offer a more effective approach.

Purpose of the Study:

• To evaluate a reading-based intervention designed to reduce weight bias.
• The intervention aimed to decrease beliefs about weight controllability, reduce stereotypes, and promote empathy.

Main Methods:

• 319 participants were randomly assigned to read either a fictional narrative about a peer with obesity or informational material on overweight and obesity.
• The study compared outcomes between the intervention and control groups.

Main Results:

• The reading intervention significantly reduced overall weight bias and beliefs about weight controllability from baseline to 1-month follow-up.
• No significant differences were observed in bias related to character disparagement or physical unattractiveness.
• Results were controlled for body mass index and gender.

Conclusions:

• A combination-approach reading intervention is a promising strategy for reducing overall weight bias.
• Future research should focus on enhancing interventions to specifically address negative attitudes related to character and attractiveness.
• Findings can inform programs aimed at reducing weight stigma and improving mental health.
