Abstract

OBJECTIVE: The Semi-Structured Assessment for Drug Dependence and Alcoholism (SSADDA) yields Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) diagnoses for a variety of psychiatric disorders, including alcohol and drug dependence. Using generalizability theory, we sought to ascertain the sources of unreliability for DSM-IV substance-dependence diagnoses and their criterion counts. METHOD: Two hundred ninety-three subjects (52.2% women) were interviewed twice over a 2-week period, and a generalizability coefficient and an index of dependability (with confidence intervals) were calculated for each dependence category. RESULTS: Overall, there were good-to-excellent reliabilities for the more common diagnoses and criterion counts, including tobacco, alcohol, cocaine, and opioid dependence. The reliabilities were not as good for marijuana dependence and the less common diagnoses of stimulant, sedative, and other drug dependence. There was greater variability between interviewers (inter-rater reliability) than occasions (test-retest reliability). However, for most diagnoses, the subject by occasion variability was larger than the subject by interviewer variability, indicative of greater consistency in the contribution by interviewers to the ordering of subjects than in the contribution by subjects themselves between the two interviews. CONCLUSIONS: These results are consistent with prior findings that the SSADDA yields reliable diagnoses and criterion counts for the more prevalent substance-dependence diagnoses. The present analysis extends these findings by showing that the greatest source of unreliability was the subjects' report. This underscores the need for efforts to increase the reliability of substance-dependence diagnoses (and by extension other self-reported phenotypic features) by enhancing the consistency of the information provided by the subjects interviewed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
