- Abstract
Introduction and objective: Instruments for diagnosing attention-deficit/ hyperactivity disorder (ADHD) in childhood are well validated and reliable, but diagnosis of ADHD in adults remains problematic. To date the Conners Adult ADHD Rating Scales (CAARS) are the international standard for questionnaire assessment. The current study is the first to evaluate a German version of the CAARS. Methods: We recruited 850 healthy German subjects to fill out the CAARS and questions on socio-demographic variables. Explorative (EFA) and confirmative factor analyses (CFA) were conducted to obtain factor structure and to replicate the original American-model. Results: EFA of the German sample results in a six factor solution explaining 52% of the variance; CFA based on the original American-model showed a high model-fit. Analyses of normative data showed significant influences of age, gender, and education level on the emerging subscales. Discussion: EFA results in different factors for the German sample, but CFA shows such a high model fit that the use of each instrument in its cultural context is justified with comparable ratings of symptomatology. Conclusion: The German version of the CAARS is a cross-culturally valid instrument for the assessment of adult ADHD.
