INTRODUCTION: The quality of life related to health of children with pediatric neuromuscular diseases is studied from the perspective of self-perception and parent-perception. It is therefore essential to dispose valid scales such as Pediatric Quality of Life inventory (PedsQL) Neuromuscular Module for its correct assessment. AIM: To assess the validity and reliability of the Spanish version of PedsQL Neuromuscular Module for self-perceived and parent-perceived quality of life of children aged 8-18 with neuromuscular disorders. SUBJECTS AND METHODS: The cognitive validity of the Spanish version of PedsQL was carried out with Mapi Research Trust permission. Subsequently, a test-retest was performed with 90 children volunteers with neuromuscular diseases, 50 aged 8-12 and 40 aged 13-18, and 85 of those children's parents. This allowed an evaluation of PedsQL intra-observer concordance and internal consistency. Finally, construct validity was evaluated through factor analysis. RESULTS: The Cronbach alpha and all correlation intra-observer coefficients were higher than 0.8, indicating excellent validity and reliability and a higher internal consistency. The construct validity analysis suggested that a new construct with more might be a better fit than three and it will be able to explain a higher percentage of variability. CONCLUSIONS: The Spanish version of PedsQL Neuromuscular Module for self-perceived and parent-perceived quality of life of children aged 8-18 presented excellent validity and reliability.
