Methods Following a specific methodology for cultural adaptation, direct and back translations were carried out, together with cognitive interviews with pediatric occupational therapists, to analyze the comprehensibility of the translated version.

Finally, inter-rater reliability was analyzed in a sample of typically developing children aged between 4 years old and 6 years and 11 months (n = 12).
