Hypothesis
This study aimed to evaluate comorbidity for Major Depression in a large Eating Disorder sample and both personality and anger as clinical characteristics of patients with Eating Disorders and Major Depression.
Conclusion
The study found that 19.5% of Eating Disorder patients suffered from comorbid Major Depression, with significant differences among diagnostic subtypes.
Supporting Evidence
- 19.5% of Eating Disorder patients were found to have comorbid Major Depression.
- 48.7% of patients reported clinically significant depressive symptomatology.
- 73% of patients with Major Depression exhibited irritable mood.
- High Harm Avoidance and low Self-Directedness predicted Major Depression independently of Eating Disorder severity.
Takeaway
This study looked at people with eating disorders and found that many also had depression, especially those who get angry easily.
Methodology
The study assessed 838 Eating Disorder patients using psychiatric evaluations and psychometric questionnaires.
Potential Biases

Limitations
The study lacked a control group of healthy subjects and did not consider lifetime comorbidity.
