Transcript of PDMS-2
The Peabody Developmental Motor Scales - second edition
The PDMS-2 is an early childhood motor development program that assess and trains gross and fine motor skills
This assessment can be used from birth until 5 years of age
(PDMS-2) is composed of six subtests that measure
interrelated abilities in early motor development
Reflexes (Re) - This subtest measures aspects of a child's ability to automatically react to environmental events.
Because reflexes typically become integrated by the time a child is 12 months old, this subtest is given only to children
ages 2 weeks through 11 months.
Stationary (St) - This subtest measures a child's ability to sustain control of the body within its center of gravity and
Locomotion (Lo) - This subtest measures behaviors that children use to transport themselves from one place to another,
such as crawling, walking, running, hopping, and jumping forward.
Object Manipulation (Ob) - This subtest measures a child's movements needed to catch and throw objects. Because
these skills do not become apparent until a child reaches 11 months of age, this subtest is only given to children ages 12
months and older.
Grasping (Gr) - This subtest measures a child's ability to use his or her hands. It begins with the ability to hold an object
with one hand and progresses up to actions involving the controlled use of the fingers of both hands to button and
Visual-Motor Integration (Vi) - This subtest measures a child's ability to use his or her visual perceptual skills to perform
complex eye-hand coordination tasks such as reaching and grasping for an object, building with blocks, and copying
All of the PDMS-2 subtests contribute to a
Total Motor Quotient
(TMQ). This score can most appropriately be thought of
as the best estimate of overall motor abilities. In addition, each subtest contributes to either the
Gross Motor Quotient
(GMQ) or the
Fine Motor Quotient
Gross Motor Quotient (GMQ) - This quotient measures the ability to utilize the large muscle systems to move from place
to place, assume a stable posture when not moving, react automatically to environmental changes, and catch/throw
Fine Motor Quotient (FMQ) - This quotient measures a child's ability to use his or her hands and arms to grasp objects,
stack blocks, draw figures, and manipulate objects.
The new edition has updated data, the absence of gender and racial bias, norms stratisfied by age, and is valid for a wide variety of subgroups
The PDMS-2 was normed on 2,003 children residing in 46 U.S. states and one Canadian province
Administration: 20-30 minutes for each motor-related subtest or 45-60 minutes for entire assessment
The PDMS-2 has been found to be the most valid and reliable test of its kind
