New version of the Pediatric Evaluation of Disability Inventory (PEDI-CAT): translation, cultural adaptation to Brazil and analyses of psychometric properties

Abstract

BackgroundThe Pediatric Evaluation of Disability Inventory-Computer Adaptive Test (PEDI-CAT), developed with innovative measurement methodologies, evaluates functioning of children and youth, from 0 to 21 years, with different health conditions. It is a revision of an earlier instrument (PEDI) that has been used in national and international clinical practice and research. It was felt to be necessary to make this new version (PEDI-CAT) available in Brazil.ObjectivesTranslate and culturally adapt the PEDI-CAT to the Brazilian-Portuguese language and test its psychometric properties.MethodThis methodological study was developed through the following stages: (1) translation, (2) synthesis, (3) back-translation, (4) revision by an expert committee, (5) testing of the pre-final version, and (6) evaluation of the psychometric properties. The 276 translated PEDI-CAT items were divided into three age groups (0-7, 8-14, and 15-21 years).ResultsThe PEDI-CAT translation followed all six stages. The adaptations incorporated cultural and socioeconomic class specificities. The PEDI-CAT/Brazil showed good indices of inter-examiner (intraclass correlation coefficient-ICC=0.83-0.89) and test-retest (ICC=0.96-0.97) reliability, good internal consistency (0.99) and small standard error of measurement in all three age groups (0.12-0.17). Factor analyses grouped the items from the three functional skills domains into one factor, and items from the responsibility scale into three factors, supporting the adequacy of these factor solutions to the conceptual structure of the instrument and the developmental model.ConclusionThe PEDI-CAT/Brazil is a theoretically consistent, culturally appropriate, and reliable instrument. Its availability in Brazil will contribute to the evaluation and measurement of functional outcomes from clinical interventions, longitudinal follow-up, and rehabilitation research.

“…The overall score is transformed to a normative score (based on age) and a continuous score that will be used in the analyses. The PEDI-CAT has been translated and adapted culturally to Brazil [43].…”

“…The PEDI-CAT is the computerized version of PEDI and has been translated and adapted culturally to Brazil [33]. It is answered by the children's caregiver and has an item bank divided into two domains: (1) mobility, which includes 75 items ranging from basic motor skills (e.g., sitting without support) to more difficult motor skills (e.g., running or climbing a step ladder).…”

“…En adultos, se reporta el uso de escalas como escala de Tinetti, escala FIM (Functional independence measure), Time up and go, índice de Barthel y fugl meyer, estas predicen la funcionalidad en miembros superiores e inferiores en actividades como agarres funcionales, alcances funcionales y actividades de la vida diaria (Canbek, 2013) (Gautschi, 2016) (Hwang, 2016) (Kato, 2007) (Lugo, 2007) (Lundquist, 2016) (Ohura, 2014) (Oveisgharan, 2006) (Page, 2012) (Panella, 2008) Instrumentos de evaluación fisioterapéutica en población adulta y pediátrica Utilizadas en la práctica clínica; una revisión de la literatura presenten algún tipo de discapacidad que altere la funcionalidad y la realización de actividades de la vida diaria. Adicionalmente, estas escalas poseen índices de validez y confiabilidad altos para su utilización en la práctica clínica (Berg, 2016) (Compagnone, 2014) (Dumas, 2015) (Eliasson, 2006) (Graham, 2004) (Grilli, 2006) (Lee J.
