¹Present refers to a rating of 3 on signs, symptoms, or criteria assessed during the SCID-based research interview, consistent with scoring on the SCID (First et al., 2010); likewise “subthreshold” refers to a rating of 2 on these criteria.

²Criteria referenced in the table refer to the DSM-IV-TR criteria rated in the SCID for MDE and PTSD, respectively (American Psychiatric Association, 2000; First et al., 2010).
