Abstract

Recently, the American Psychiatric Association published the 5th edition of the DSM (DSM­5), making several important changes from the DSM­IV­TR. At this time, there is no published structured interview for DSM­5 psychiatric disorders. Furthermore, most existing structured interviews assess only the diagnostic criteria, without gathering specific information needed for differential diagnosis and treatment planning. The Diagnostic Interview for Anxiety, Mood, and OCD and Related Neuropsychiatric Disorders (DIAMOND; Tolin et al., 2013) is a semistructured clinical interview that was designed to assess the diagnostic criteria for a range of DSM­5 disorders, with additional clinical information (e.g., associated cognitive, emotional, and behavioral features; common differential diagnoses) gathered for the Anxiety, Mood, and OCD and Related Disorders. The poster will introduce the readers to this new diagnostic interview, which has gone through several rounds of initial feasibility testing, with iterative feedback from users at various stages of professional development. Mean (SD) administration time is 74.0 (30.2) minutes, or 32.6 (24.0) minutes per DSM­5 diagnosis, making the DIAMOND feasible for use in clinical, research, and training settings. Data collection is ongoing (current n = 21) to evaluate the reliability and validity of the DIAMOND for diagnosing Anxiety, Mood, and OCD and Related Disorders. By the time of the conference, we anticipate having data from at least 50 adults seeking psychiatric treatment in various settings and levels of care (e.g. specialty outpatient clinic for anxiety and OCD related disorders, schizophrenia rehabilitation program, an inpatient psychiatric unit). Interrater reliability (IRR) will be examined by administering the DIAMOND twice within a 48­hour period by two different interviewers. Test­retest reliability will be examined by administering a third DIAMOND approximately one week from the initial administration by one of the first two interviewers. For evaluating convergent and divergent validity analyses, we administered a range of self­report measures that address the diagnoses covered by the DIAMOND (obsessive­compulsive disorder, body dysmorphic disorder, hoarding disorder, trichotillomania, skin­picking disorder, specific phobia, social phobia, panic disorder, depression, mania, posttraumatic stress disorder, psychosis, eating disorders, somatoform disorders, substance use disorders, and attention deficit­hyperactivity disorder). IRR will be determined by calculating kappa coefficients for each diagnosis and intraclass correlation coefficients for each severity rating between rater 1 and rater 2 at time 1.Test­retest reliability will be determined by calculating kappa coefficients for each diagnosis and intraclass correlation coefficients for each severity rating for the same rater at times 1 and 2. Convergent and divergent validity will be determined by calculating between­samples t­tests, using the presence and absence of each Anxiety, Mood, and OCD and Related Disorder as the independent variables, and scores on the self­report measures as the dependent variables. Findings will be discussed in light of clinical utility and research applications.
