Lifetime diagnoses based on the SCID-I/NP (hereafter, referred to as the SCID) were the main outcome measures. We required that each disorder be characterized by clinically significant functional impairment (e.g., absenteeism,) or clinically significant distress (e.g., pervasive distress about the symptoms, seeking treatment). The median interval between screening and the SCID was 3 months (range: 1-15). Graduate students, research assistants, or postdoctoral fellows were interviewers who were trained through self-study, didactics, role-playing, observations, and tests of diagnostic ability. Interviewers were also trained to assess not otherwise specified (NOS) diagnoses. When a NOS diagnosis was assigned, interviewers noted which criteria set the symptoms most closely resembled. Interviewers presented assessments to doctoral-level supervisors at diagnostic meetings. The present study only includes analyses of clinically-significant cases that met full criteria for one or more DSM syndromes.
