[Basler drug- and alcohol-questionnaire. First experiences in the construction of a test instrument for evaluation of dependency of drug-and/or alcohol-consumers (author's transl)].
In order to provide an estimation of the degree of drug and/or alcohol dependency the authors designed a questionnaire. In this paper the basic steps of item analysis, factor analysis and calculation of reliability (split-half-method) are reported. After elimination of 6 items out of 65 the item-metric and factorial characteristics as well as the reliability of the instrument could be judged as satisfactory. On the item level two factor analytical solutions were interpreted. The first one showed one factor covering the general concept of dependency, the second one suggested a 3- dimensional differentiation in terms of 1. negative self-concept, 2. obsessional traits, and 3. addictive illness behavior.
