1. Development: Items were developed based on the DSM-5 and ICD-11 criteria 2. Evaluation: Psychometric evaluation of the symptoms checklists will be carried out in both a clinical sample (N= 300; 4;00 -17;11 years) and a community sample (N= 300; 4;00 -17;11 years). This evaluation includes item analyses as well as analyses of the factorial structure, reliability and convergent, divergent and differential validity. The psychometric properties of symtom checklist are to be assessed at the Center for Child and Adolescent Psychotherapy (CEKIP Cologne) at the University Hospital of Cologne. In addition, a community sample is planned through residents' registration offices. Both samples will receive a written informed consent form and the required questionnaires. 3. Standardization: Standards will be calculated for the clinical sample and the community sample. 4. Further study objectives: Correlations with comorbid symptoms and psychosocial impairments.
