Do German Children Differ? A Validation of Conners Early Childhood™.

The present study aimed to validate the German version of the Conners Early Childhood (EC)™ among German-speaking children. A total of 720 parental and 599 childcare provider ratings of 2- to 6-year-old children were surveyed throughout Germany. Validity was assessed by calculating exploratory factor analyses (EFAs) and confirmatory factor analyses (CFAs), and a series of multivariate analyses of variance (MANOVAs) to analyze associations between Conners EC™ symptom ratings and sociodemographic variables.
