Posttraumatic Stress Disorder and Major Depressive Disorder: Investigating the Role of Overlapping Symptoms in Diagnostic Comorbidity
Abstract
Studies of posttraumatic stress disorder (PTSD) have found high levels of comorbid major depressive disorder (MDD). One reason suggested for the comorbidity is the symptom overlap (contaminated symptoms) between the disorders. The present study investigated the contribution of contaminated symptoms (anhedonia, concentration, and sleep problems) to the comorbidity of PTSD and MDD. PTSD symptoms were subdivided into two groups: the contaminated symptoms and the 14 unique symptoms. It was speculated that if the contaminated symptoms are responsible for the comorbidity, then they will show less specificity than the unique symptoms, will be less highly correlated with a PTSD symptom total count, and be more frequently endorsed in PTSD patients with than without MDD. These hypotheses were tested in a sample (N = 1300) of psychiatric outpatients, 260 of whom had lifetime PTSD. None of the hypotheses were supported, thereby suggesting that the comorbidity between PTSD and MDD is not an artifact of symptom overlap.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
