The purpose of this study was to examine the psychometric proprieties of the Peabody Developmental Motor Scales II (PDMS-2) (FOLIO; FEWELL, 2000), using a Portuguese sample group. The Portuguese version of PDMS-2 was applied, according to the manual guidelines of PDMS-2, to 540 children, aged 36 to 71 months from fifteen preschools. The results of the confirmatory factor analysis (S-Bχ2=3.3, p=.349; CFI =1.0, NFI =.99, NNFI=.99, RMSEA =.013) support that the Portuguese version presents a model of two factors (Fine and Gross Motor) as does the original version. Most of the subtests showed a good internal consistency (α = .76 to .95) and good test-retest reliability (ICC = .85 to .95). These findings indicate that the Portuguese version PDMS-2 is an accurate and valid tool to assess the gross and fine motor skills of Portuguese preschoolers.
