Background:
The Peabody Developmental Motor Scales - Second Edition (PDMS-2) has been used by health and educational professionals to assess the gross and fine motor skills of children with typical development, motor and/or cognitive delays, and disabilities.
Aim:
Investigate the validity and reliability of PDMS-2 for use in Brazil.
Methods:
For content validity, 13 professionals participated in the study. For construct validity, a sample of 637 children from birth until 71 months (0-23 months: n = 399; 24-71 months: n = 238) was assessed with the PDMS-2.
Results:
The PDMS-2 administered to the Brazilian population has psychometric characteristics equivalent to the original version.
Conclusion:
PDMS-2 is a valid and reliable tool for evaluating Brazilian children's motor development and providing appropriate support for clinical and educational intervention plans and follow-ups.
