Translation, cross‐cultural adaptation, validity and reliability of the Brazilian Portuguese version of Activity Scale for Kids questionnaire

Abstract

Background: The Activity Scale for Kids (ASK) assesses the physical disability of children (5 to 15 years old) with neurological, orthopaedic or rheumatic diseases. The objective of this study was to translate and cross-culturally adapt the ASK for Brazilian Portuguese and assess the validity and reliability of the instrument.Methods: A total of 67 children and adolescents with musculoskeletal, neurological or rheumatic diseases participated in the study. We evaluated the comprehension of the pre-final version of the questionnaire in 24 participants and reliability and validity in the other 43 participants. The translation and adaptation of ASK to Brazilian Portuguese followed guidelines from previous studies. The validity of the Brazilian Portuguese version of the ASK was verified through Spearman's correlation with the Pediatric Quality of Life Inventory™ Version 4.0 (PedQL). Intraclass correlation coefficient verified inter-and intra-evaluator reliability, while internal consistency was assessed using Cronbach's alpha. Scores were used to assess the standard error of the mean and minimal detectable change. Results:The Brazilian Portuguese version of the ASK presented excellent reliability, internal consistency, agreement and moderate correlation with PedsQL (0.522, P < 0.001) between ASK performance and PedsQL; 0.537, P < 0.001 between ASK capacity and PedsQL. Conclusion:The Brazilian Portuguese version of the ASK has good validity and reliability and may be used by professionals and researchers to assess the functioning of children and adolescents with disabilities.

The global estimate of children and adolescents with disabilities is approximately 150 million (World Health Organization & World Bank, 2011), with Brazil having approximately 12.4 million people; 4.4% are children and adolescents (from 0 to 17 years old), and 1.0% present physical disabilities (Malta et al., 2016). Physical Disabilities in children and adolescents occur mainly due to non-transmissible chronic diseases, such as rheumatic, neurological

Psychometric properties of the Spanish version of the Activities Scale for Kids (ASK): reliability, validity and the Rasch model

“…The aim of the present study was to validate the Spanish version of both the ASKc and ASKp scales. The results of the analysis yielded evidence on the reliability and validity of the scales, both of which were considered adequate for a test of these characteristics and were consistent with the data obtained from both the original version and other versions 13 14 21 23–27. These results therefore indicate that ASK is an ideal instrument for evaluating problems of functionality and/or disability among children in the field of clinical rehabilitation in Spain.…”

“…ASK has been translated into Italian, 14 21 Spanish, 22 Portuguese, 23 Brazilian, 24 Persian or Farsi, 25 German 26 and Nepali, 27 and analyses of the psychometric properties of all versions yielded adequate results. However, there are at present no validated versions of ASKc and ASKp in Spanish.…”
