Summary
Witnessing discrimination against LGBTQ+ individuals (vicarious trauma) increases eating disorder risk. This risk is directly linked and indirectly mediated by emotional dysregulation and low self-esteem.
Area of Science:
- Psychology
- Public Health
- Sociology
Background:
- Minority stress is linked to eating disorders.
- Limited research exists on vicarious trauma from witnessing heterosexist events in LGBTQ+ populations.
Purpose of the Study:
- Examine the association between vicarious trauma and eating disorder risk.
- Investigate the mediating roles of emotional dysregulation, self-esteem, and shame.
Main Methods:
- Anonymous online survey of 376 LGBTQ+ individuals in Italy.
- Self-report questionnaires on heterosexist experiences and eating behaviors.
- Descriptive, bivariate, and mediation analyses using the PROCESS macro.
Main Results:
- Significant positive associations found between vicarious trauma, eating disorder risk, emotional dysregulation, low self-esteem, and shame.
- Vicarious trauma had a direct effect on eating disorder risk.
- Indirect effects of vicarious trauma on eating disorder risk were mediated by low self-esteem and emotional dysregulation.
Conclusions:
- Vicarious trauma directly impacts eating disorder risk in LGBTQ+ individuals.
- Emotional dysregulation and low self-esteem partially mediate this relationship.
- Interventions addressing minority stress and its consequences are crucial for LGBTQ+ health equity.
