Regarding the consent form, the information sheet and the rest of the questionnaires which were in English, first they were translated by the researcher into Greek. All translations were reviewed by two Greek parents and a Greek Lecturer in Linguistics at University of Cambridge for understanding and relevance of the translated terms. All translations were adjusted according to the reviewers' comments. At the end, a Greek-American Health Professional checked if the final Greek translations matched the original English ones. The Conners and the SQD have officially been translated in Greek.
