Knowledge of Attention Deficit Disorders Scale - deutsche Fassung
The KADDS is a questionnaire to measure a person's expertise on attention deficit hyperactivity disorder (ADHD). It was developed by Sciutto and colleagues (2000) to assess existing and missing knowledge and misconceptions among parents of children with ADHD, their teachers and educators, and other educational and clinical professionals. The questionnaire can also be used by students and other adults. The KADDS contains 36 statements on ADHD, divided into the scales (1) Symptoms and diagnosis of ADHD, (2) Treatment of ADHD, (3) General aspects of the disorder in terms of cause or course. Reliability: The internal consistency is Cronbach's Alpha = .69 (total scale) or Alpha = .29-.52 (scale level). Validity (content and construct validity): During the development of the KADDS (original English version) only items were included in the scale whose content statements were empirically confirmed and sufficiently documented. The intercorrelations between the subscales are significant and moderately pronounced. Participants of a further training on ADHD scored significantly better on the KADDS items in the post- and follow-up test than before the workshop (= change sensitivity).
