Peabody Developmental Motor Scale – 2nd Edition [PDMS-2]
The PDMS-2 assesses fine and gross motor skills of children from birth to 5 years old. The four gross motor subtests are reflex, stationary, locomotion, and object manipulation, while the two fine motor subtests are grasping and visual-motor integration. The total score is determined by the sum of the points of each subtest. The manual reports a good index of internal consistency for each subtest (α = 0.89 to 0.95) and for each motor quotient (0.96 to 0.97), acceptable temporal stability through the test-retest with an interval of one week (α = 0.73 to 0.96 depending on the age level), and high inter-observer fidelity (which varied between 0.97 to 0.99 for subtests and between 0.96 and 0.98 for the motor quotients) [
