Alcohol abuse and dependence: consistency in reporting of symptoms over ten years.
The present study assesses the stability of the diagnosis of alcoholism among a sample of St Louis, USA Epidemiological Catchment Area Study participants. The Diagnostic Interview Schedule was used at Time 1 and the Composite International Diagnostic Interview--Substance Abuse Module was used at 10-year follow-up. Alcohol abuse and dependence were diagnosed using DSM-III criteria. Kappa values and Yule's statistics for agreement in diagnoses, criterion groups and individual symptoms are reported. Fair to good measurement of agreement was shown for any diagnosis of alcohol abuse or dependence versus no diagnosis. The criterion group for "impairment in social or occupational functioning" showed the highest agreement of the three criterion groups studied. Agreement was lower for individual symptoms of alcoholism. Incident cases accounted for some of the inconsistency in responses over 10 years. Other types of inconsistency found were changing response from yes to no, changing response from no to yes but not meeting the definition of an incident case, and misstating age of onset of symptoms. Mean per cent inconsistency across all symptoms was 11.4%. Further research regarding reasons for inconsistencies is needed.
