Intra-rater Reliability for the Questionnaire on Activity Limitations and Participation Restrictions of Children With ADHD

Introduction: Questionnaires for evaluating activity limitations and participation restrictions in children with ADHD (CLARP-TDAH) has recently been developed in Colombia, based on the suggestions made by the WHO from the International Classification of Functioning, Disability and Health (ICF), allowing clinical evaluation beyond an evaluation of the functionality and functioning of children in their family and school environments. Previous research with the questionnaire proved useful in the multidisciplinary approach of Colombian children with ADHD. This study determines the level of intra-rater reliability for questionnaires CLARP-TDAH Parents and Teachers. Methods: The study included a non-random sample of 203 Colombian children attending school and diagnosed with ADHD. Intra-rater reliability and the reproducibility of the results was determined using the Kappa index. The informants were parents and teachers. Results: Kappa values >0.7 were obtained for the intra-rater reliability of the questionnaire domains of CLARP-TDAH Parents, while for CLARP-TDAH Teachers domains these values were >0.8. Conclusions: CLARP-TDAH questionnaires are a tool with a good level of intra-rater reliability, which allows a reliable assessment of activity limitations and participation restrictions in order to determine the level of functioning at home and school.
