The adult developmental coordination disorders/dyspraxia checklist - German: Adapted factor structure for the differentiation of DCD and ADHD

Abstract

Background: The Adult Dyspraxia/DCD Checklist (ADC) is the only existing self-report questionnaire to screen adults for potential Developmental Coordination Disorder (DCD). It was developed in English and Hebrew, however, its factor structure has not yet been assessed. Aims: The goals of the current study were to (1) develop and refine a German translation, (2) explore the emerging factors in a new and restructured ADC in German and apply this structure to an English ADC, and (3) explore its potential for distinguishing DCD versus ADHD. Method: In a series of three studies, we assessed comprehensibility of the translation and revisions to the questionnaire. We further examined subscale structure in a sample of N=148 individuals with DCD or ADHD and retested it in an English-speaking sample (N=134). Results: Overall, we found decent reliability and construct validity for the German ADC. Three components emerged with themes of fine motor coordination, gross motor coordination, and executive functions which had strong psychometric properties in German and English. Conclusions: The studies collectively highlight the German translation is effective and  has strong potential to differentiate DCD and  ADHD. Most notably, there are unique symptom profiles in motor and executive functioning difficulties in adults with DCD or ADHD.
