Hypothesis

Anorexia nervosa patients will show more severe suicide attempts than those with bulimia nervosa and non-eating disordered attempters.

Conclusion

Anorexia nervosa patients have more serious suicide attempts, which may explain their higher suicide rates.

Supporting Evidence

  • AN patients were more likely to have made a serious attempt.
  • AN patients had a higher expectation of dying from their attempts.
  • Clinical markers of eating disorder severity were linked to the seriousness of attempts.

Takeaway

People with anorexia nervosa are more likely to try to kill themselves in a serious way compared to those with bulimia or no eating disorders.

Methodology

Potential Biases

Participant Demographics

Participants were aged 18-75, French-speaking, and had Western European ancestry.
