Introduction: The purpose of the present research is to compare the Turkish translations of school and home versions of the Scales for Diagnosing Attention-Deficit/Hyperactivity Disorder (SCALES) developed by Ryser and McConnell with respect to age and gender and to examine the correlation between the two scales. Method: The research was conducted with 102 teachers and parents of 891 children aged between 5.0 and 14.11 years. 656 scale forms of parents returned to us were included in the study. The teachers filled in teacher information form, child information form, SCALES-School Rating Scale and the Turkish version of Conners' Teacher Rating Scale. The parents filled in family information form, child information form and SCALES-Home Rating Scale and the Turkish version of the Conners' Home Rating Scale. Results: When SCALES-Home Rating Scale and SCALES-School Rating Scale scores of each age group were compared using t-test, it was observed that the difference in all sub-scale scores in the 5-9 age group was significant and it was also observed that in the 10-13 and 13+ age groups, the difference was significant only in the hyperactivity field. The correlation between SCALES-School Rating Scale and SCALES-Home Rating Scale was investigated. The correlation between sub-scales measuring the same abilities was found to be between 0.1 and 0.26. Conclusion: We assume that the Turkish version of the SCALES is a valid and reliable instrument for diagnosing ADHD. Since SCALES-Home Rating Scale scores were higher than SCALES-School Rating Scale scores and the correlation between the two scales was low, we assume that the objectivity of parents' ratings was limited.. Future validity studies on diagnosed children are needed.
