The Validity of the Short Alcohol Dependence Data (SADD) Questionnaire: a short self-report questionnaire for the assessment of alcohol dependence

The evidence for the unitary nature of alcohol dependence is discussed and the usefulness of existing instruments to measure dependence is reviewed. Three separate studies are presented that support the validity of SADD. Several measures of construct and concurrent validity are investigated including comparison with the SADQ and EADS. Attention is drawn to the discriminating characteristics of SADD in the mild/moderate dependence range.
