Development and validation of a short form of the German Developmental Behaviour Checklist for Teachers (DBC-T)

The proposed short form complements the full version of the DBC-T and offers a time-efficient means of assessing multiple students simultaneously, as often required in school and research contexts. WHAT THIS PAPER ADDS?: This study develops and validates a short form of the German Developmental Behaviour Checklist (DBC-T) that assess emotional and behavioural problems in children and adolescents with intellectual disability. The proposed short form retains the subscale format of the DBC-T, allowing for interpretation of the subscale scores. The short form demonstrated good psychometric properties. As a reliable, valid and time-efficient instrument, the short version may supplement the full version.
