ADHD Traits in German School-Aged Children: Validation of the German Strengths and Weaknesses of ADHS Symptoms and Normal Behavior (SWAN-DE) Scale.

Objective: The Strengths and Weaknesses of ADHS-Symptoms and Normal Behavior (SWAN) Scale has been developed to support the dimensional assessment of ADHD symptoms by capturing variance on both poles of the ADHD continuum. The present study provides the first validation of the German version of SWAN (SWAN-DE).

Method: Based on a sample of N = 343 children from the general population and N = 62 children with ADHD, both aged between 8 and 18 years, normality, internal consistency, test-retest reliability, and different validity indices were examined.
