The Use of the Short‐Form Alcohol Dependence Data Questionnaire (SADD) in Brazilian Alcoholic Patients *

Abstract

Summary The possibility of applying the short‐form Alcohol Dependence Data questionnaire (SADD) to an interview situation was tested in an alcoholic sample. This was in contrast to using the self‐completion questionnaire as was originally proposed. The correlation between the SADD, when applied to an interview situation and the SADD, when used as a self‐completion questionnaire, as evaluated by the Spearman correlation coefficient, was r = 0.81. A test‐retest reliability using the self‐completed form provided a correlation of r = 0.90. Split‐half reliability obtained far both the interview and self‐completion questionnaire yielded correlations of r = 0.88 and r = 0.82 respectively. The interview version of the SADD can, therefore, be utilised with illiterate subjects. Furthermore, it has provided data showing that the SADD clearly discriminated between a sample of normal volunteers ( n = 55) and a sample of alcoholics ( n = 50).
