BACKGROUND: While it is know that depressive symptoms are common in eating disorders (EDs), it is unclear whether these symptoms differ from those in depressive disorders (DDs) with regard to severity and quality.
METHODS: Beck Depression Inventory II (BDI-II) scores at admission to treatment of 4.895 inpatients with a unipolar DD and 3.302 inpatients with an ED were compared by means of independent t-tests and Cohen's d effect sizes with regard to: (1) overall severity (BDI-II total score), (2) six facets of depression identified by non-metric multidimensional scaling of the German BDI-II validation sample, and (3) individual items.
RESULTS: (1) The two groups did not differ with regard to the BDI-II total score. (2) There was no difference in the facet Depressive Core Symptoms. Patients with DDs had higher scores for Diminished Activation (d = 0.40) and patients with EDs had higher scores for Negative View of Self (d = 0.40). (3) Patients with DDs showed higher score on the item Loss of Energy (d = 0.48), while patients with EDs sored higher on Self-Dislike (d = 0.48) and Changes of Appetite (d = 0.48).
CONCLUSIONS: Depression in EDs seems to be as severe as in DDs and may show similar core aspects (e.g., Sadness, Loss of Pleasure). Qualitative differences suggested that individual additional symptoms of depression need to be differently addressed in therapy. The pronounced Negative View of Self in EDs is in line with the "core low self-esteem", a central component of the prevalent transdiagnostic model of EDs.
