Test-retest reliability of the computer-assisted DIA-X-5 interview for mental disorders

Abstract

Background: There is a need of comprehensive standardized diagnostic assessment tools of psychopathology that match recent changes in diagnostic classification systems, such as the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Therefore, the computer-assisted DIA-X-5 was developed and its test-retest reliability was explored. The DIA-X-5 is based on the DIA-X/M-CIDI (Diagnostisches Expertensystem für psychische Störungen/Munich-Composite International Diagnostic Interview) which referred to the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Methods: A convenience sample (N = 60, age: 15-67) was interviewed twice with the computer-assisted DIA-X-5 interview, on average nine days apart, by trained and blinded interviewers. The DIA-X-5 is a standardized instrument for research purposes covering symptoms, syndromes and diagnoses from eleven classes of mental disorders according to the DSM-5 with matching F codes of the 10th edition of the International Classification of Diseases (ICD-10). Results: Kappa values ranged from 0.90 for post-traumatic stress disorder to 0.30 for social anxiety disorder. For age of onset and age of recency, test-retest reliability as measured by intra-class correlation was satisfying with values above 0.90 for most disorders. Conclusions: Test-retest reliability of the DIA-X-5 syndromes and diagnoses were comparable to those of previous DSM-IV/DIA-X diagnoses for most disorders. Due to low case numbers for some diagnoses, further research in larger samples is required.

The interaction of 5‐HTT variation, recent stress, and resilience on current anxiety levels in adolescents and young adults from the general population

“…Diagnostic status was assessed with an updated version of the Munich composite international diagnostic interview (Wittchen & Pfister, 1997) providing lifetime and 12‐month diagnoses of a range of mental disorders according to Diagnostic and Statistical Manual of Mental Disorders , fifth edition (Hoyer et al, 2020). The fully standardized computer‐assisted personal interviews were conducted face‐to‐face by trained clinical interviewers.…”

The Behavior and Mind Health (BeMIND) study: Methods, design and baseline sample characteristics of a cohort study among adolescents and young adults

“…The DIA‐X/M‐CIDI provides lifetime and 12‐month diagnoses for a wide range of mental disorders including anxiety, depressive, bipolar, substance use, somatic symptom/somatoform, psychotic disorders, and eating disorders and was originally designed to assess DSM‐IV (APA, ) and ICD‐10 (WHO, ) criteria. The updated version was created to asses diagnoses according to DSM‐5 (APA, ) and a broader range of disorders (e.g., also disruptive behavior, attention‐deficit/hyperactivity, and impulse‐control disorders; DIA‐X‐5; Hoyer et al, submitted). The fully standardized computer‐assisted personal interviews were conducted face‐to‐face by trained clinical (psychology/medical) interviewers.…”

How current and past anxiety disorders affect daily life in adolescents and young adults from the general population—An epidemiological study with ecological momentary assessment

“…Age at last occurrence reports of participants may also have been biased by recall error. However, time based information of the Composite International Diagnostic Interview revealed good ICCs (Hoyer et al, 2020; Kessler & Üstün, 2004; Wittchen et al, 1998). Fourth, the present study did not control for inflation of Type 1 error.…”
