The CIDI is a fully standardised diagnostic interview designed for assessing mental disorders based on the definitions and criteria of ICD-10 and DSM-III-R. Field trials with the CIDI have been conducted in 18 centres around the world, to test the feasibility and reliability of the CIDI in different cultures and settings, as well as to test the inter-rater agreement for the different types of questions used. Of 590 subjects interviewed across all sites and rated by an interviewer and observer, 575 were eligible for analysis. The CIDI was judged to be acceptable for most subjects and was appropriate for use in different kinds of settings. Many subjects fulfilled criteria for more than one diagnosis (lifetime and six-month). The most frequent lifetime disorders were generalised anxiety, major depression, tobacco use disorders, and agoraphobia. Percentage agreements for all diagnoses were above 90% and the kappa values were all highly significant. No significant numbers of diagnostic disconcordances were found with lifetime, six-month, and four-week time frames.
OBJECTIVES: This study determined prevalence estimates of problem gambling and relationships to other psychiatric and substance use disorders. METHODS: In 1981, the Diagnostic Interview Schedule was used to collect epidemiological information on problem gambling and other disorders from 3004 adults in St. Louis, Mo. RESULTS: The lifetime prevalence of pathological gambling was 0.9%; 46% of those surveyed gambled recreationally. Problem gamblers (those reporting at least one gambling-related problem) were 9.2% of the sample and were predominately White (69%), male (78.2%), and young than nongamblers. They were at increased risk for several psychiatric diagnoses, especially for antisocial personality disorder, alcoholism, and tobacco dependence. CONCLUSIONS: Clinicians treating alcoholism and tobacco dependence may need to screen for problem gambling. Additional research in the context of increased gambling opportunities is needed.
The CIDI-SAM is a fully-structured interview that ascertains DSM-III, DSM-III-R, Feighner, RDC and ICD-10 diagnoses for alcohol, tobacco and nine classes of psychoactive drugs. It was designed at the request of the WHO/ADAMHA Task Force on Psychiatric Assessment instruments to expand the substance abuse sections of the CIDI. Using a test-retest design, the diagnostic and item reliabilities of this instrument were tested in a sample of 39 patients in substance abuse treatment at three St. Louis treatment facilities. Kappa values and their 95% confidence intervals, and Yule's Y values are reported. The average kappa for DSM-III substance disorders was 0.84, for DSM-III-R it was 0.82. We report, on the average, excellent kappa values for individual alcohol and drug symptoms. We also ascertained from the respondent's themselves the reasons why answers to specific questions might have been discordant. The findings from this unique 'discrepancy interview' are reported.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
