Validación del Cuestionario pediátrico de calidad de vida™ (Pediatric Quality of Life Inventory™) Módulo neuromuscular, versión 3. 0 en español para Argentina / Validation of the Pediatric Quality of Life Inventory™, Neuromuscular Module, version 3. 0 in Spanish for Argentina

Objetivo: Evaluar las propiedades psicométricas del Cuestionario pediátrico de calidad de vida (PedsQLTM 3.0) Módulo Neuromuscular, versión en español para Argentina, en niños entre 2 y 18 años con enfermedades neuromusculares. Población y métodos: Estudio observacional, analítico, prospectivo, de validación, realizado en el Hospital Garrahan entre el 19 de marzo de 2019 y el 9 de marzo de 2020. A los 10-15 días se realizó el retest del cuestionario para validar en los pacientes que reportaron estabilidad. Resultados: Participaron 185 niños y sus padres. Sobre la factibilidad de la herramienta, los participantes comprendieron fácilmente su contenido. La confiabilidad resultó aceptable, con una consistencia interna de 0,82 en niños y 0,87 en padres y un coeficiente de correlación intraclase en el retest de 0,70 en niños y 0,82 en familiares. Sobre la validez del constructo se confirmaron 8 de 11 hipótesis establecidas (72,7 %). Conclusión: El cuestionario fue validado en sus propiedades psicométricas

Objective: To assess the psychometric properties of the Pediatric Quality of Life Inventory™ (PedsQL™ 3.0), Neuromuscular Module, version in Spanish for Argentina, for children aged 2-18 years with neuromuscular disease. Population and methods: Observational, analytical, prospective validation study conducted in Hospital Garrahan between March 19th, 2019 and March 9th, 2020. The retest questionnaire was administered 10-15 days later to validate it among patients who reported a stable condition. Results: A total of 185 children and their parents participated. In terms of the questionnaire's feasibility, its content was easily understood by participants. Its reliability was acceptable, with an internal consistency of 0.82 among children and 0.87 among parents and a retest intraclass correlation coefficient of 0.70 among children and 0.82 among parents. In relation to the construct validity, 8 of the 11 hypotheses established (72.7 %) were confirmed. Conclusion: The questionnaire's psychometric properties were validated.

Translation and validation of the Life Satisfaction Index for Adolescents scale with neuromuscular disorders: LSI-A Brazil / Tradução e validação da escala de qualidade de vida para adolescentes com doenças neuromusculares para português do Brasil: LSI-A Brasil

ABSTRACT Objective To validate the Life Satisfaction Index for Adolescents (LSI-A) scale, parent version and patient version, for Duchenne muscular dystrophy (DMD), spinal muscular atrophy (SMA) and limb-girdle muscular dystrophy (LGMD). Methods The parent version of the instrument was divided into Groups A, B, C and D; and the patient version, divided into B, C and D. For the statistical calculation, the following tests were used: Cronbach's α, ICC, Pearson and the ROC Curve. Results The parent and patient versions of the instrument are presented, with the following results in the overall score, respectively: Cronbach's α, 0.87 and 0.89; reliability, r 0.98 and 0.97; reproducibility, ICC 0.69 and 0.80; sensitivity, 0.78 and 0.72; specificity, 0.5 and 0.69; and accuracy, 64% and 70.4%. Conclusion According to the validity and reproducibility values, the LSI-A Brazil parent and patient versions, are clinically useful to assess quality of life in DMD, SMA or LGMD and may also be useful for other neuromuscular disorders.

RESUMO Objetivo Validar a escala Life Satisfaction Index for Adolescents (LSI-A) versão pais e versão paciente para doenças neuromusculares. Método O instrumento versão pais foi dividido nos Grupos A,B, C e D; e paciente, em B, C e D. Para cálculo estatístico utilizou-se os testes α de Cronbach, CIC, Pearson e Curva ROC. Resultados Valor de Cronbach versão pais e paciente no escore geral, 0.87 e 0.89; confiabilidade,0.98 e 0.97;reprodutibilidade,entre 0.59 e 0.69 e, entre 0.58 e 0.80; sensibilidade, 0.78 e 0.72; especificidade, 0.5 e 0.69; e acurácia, 64% e 70.4% respectivamente. Conclusão Conforme a validade e reprodutibilidade, o LSI-A Brasil versão pais e paciente é útil clinicamente para avaliar a Qualidade de Vida da Distrofia Muscular de Duchenne, Amiotrofia Espinhal Progressiva ou Distrofia Muscular tipo Cinturas e pode ser usado para outras doenças neuromusculares.
