ADHD Rating Scale-IV in a sample of Spanish schoolchildren: normative data and internal consistency for teachers and parents
Introduction. The ADHD Rating Scale-IV (ADHD RS-IV) is one of the most use scales for attention deficit hyperactivity disorder (ADHD), because has cut-off point regarding age, gender and setting, but the normalization data is based on American school samples. Aim. Evaluation of cut-off point of ADHD-RS-IV for parents and teachers in a Spanish sample. Subjects and methods. The study used the score of ADHD-RS-IV from a prevalence study of ADHD in school children of 6-12 years. Using an intrasubject design between the three evaluators (parents and teachers) and the results of each subscale (IN, H/I, and TOT) according to gender and age factors. Then, we analyzed the reliability and internal consistency for each subscale and evaluator. Results. There are no significant differences between the father and the mother; but there are between teachers, and father and/or mother scores. In relation to gender factor, boys’ score is higher on inattention and hyperactivity-impulsivity than girls’. Our results show a reversal tendency in comparison with the American samples, in our case parents’ scores were significantly higher than teachers’. Conclusion. The use and normalization of the ADHD RS-IV will need to account not only for age, gender and setting but also for socio-cultural aspects.
