The PDMS–3 has five core subtests and one supplemental subtest:
Core Subtests
Body Control:
- This subtest measures the ability to move the limbs and trunk, postural reactions, standing, bending, extending, stooping, balancing, jumping upward. It is an estimated of the child’s ability to sustain control of his or her body within its center of gravity and retain equilibrium.
Body Transport:
- This subtest measures the ability to make movements that propel the child from one location to another, such as rolling, crawling, creeping, walking, running, jumping forward and sideward, sliding, hopping, and skipping.
Object Control:
- This subtest measures the ability to coordinate motor movements that require the incorporation of perception and movement, such as throwing, catching, bouncing, and kicking a ball.
Hand Manipulation:
- This subtest measures the ability to move the hands and fingers (and arms as appropriate) to complete tasks and measure dexterity. This includes manipulation of objects such as blocks, cups, and drawing instruments.
Eye–Hand Coordination:
- This subtest measures the ability to interpret visual stimuli in coordination with and–finger movements. It is an estimate of the child’s ability to integrate and use his or her visual perceptual skills to perform complex eye–hand coordination tasks.
Supplemental Subtest
Physical Fitness:
- This supplemental subtest measures the ability to perform activities like push–ups, sit ups, repetitive jumps, running speed, throwing for distance, and sit and reach/flexibility.
Composites
The PDMS–3 has three composites:
- These composites are derived from combining the results of the subtests to achieve strong and better indices of performance. The scores of these composites are more reliable and valid than the subtests.
Gross Motor Index:
- This composite is a combination for the results of the Body Control, Body Transport, and Object Control (children 16 months and older) subtests, which measure the use of the large muscle systems. This index score represents the child’s ability to us the large muscle systems to react to environmental changes, assume a stable posture when not moving, move from place to place, and catch, throw, and kick balls.
Fine Motor Index:
- This composite is a combination of the results of the Hand Manipulation and Eye–Hand Coordination subtests, which measure the use of the small muscle systems. This index score represents the child’s ability to use his or her fingers, hands, and to some extent arms to grasp objects, stack blocks, draw figures, and manipulate objects
Total Motor Index:
- This composite is formed by a combination of the results of the gross and fine motor core subtests. Because of this, it is the best estimate of overall motor abilities.
