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.
