Abstract
One hundred and sixty problem drinkers admitted to in-patient care were rated according to the severity of their alcohol dependence by means of two standarized questionnaires (SADQ and SADD). A bimodal distribution of scores previously reported with the SADQ was not reproduced with either questionnaire, but there was a highly significant correlation (r = 0.806) between the SADQ and SADD scores. There was 59% agreement between the two questionnaires in their placing of scores within three categories of dependence severity. The results suggest a degree of caution in equating current estimates of minimal, mild to moderate and severe dependence on the SADQ with low, medium and high dependence, respectively, on the SADD. Some difficulties experienced by subjects in completing the two questionnaires are discussed.
