Peabody Developmental Motor Scales Version 2

Instrument Name: Peabody Developmental Motor Scales Version 2

Abbreviation: PDMS-2

Description of Tool:

The Peabody Developmental Motor Scales Version 2 is a ClinRO + PerfO developed to assess gross and fine motor skills in children from birth through five years of age. It is composed of 249 items covering the following domains:
Reflexes (Re) (8 items)
Stationary (St) (30 items)
Locomotion (Lo) (89 items)
Object Manipulation (Ob) (24 items)
Grasping (Gr) (26 items)
Visual-Motor Integration (Vi) (72 items)

Minimum Qualification Required by COA Administrator: MA or BA

Comment:

Adapted from the Peabody Developmental Motor Scale published in 1983

Year: 2000

Objective of Development:

To assess gross and fine motor skills in children from birth through five years of age

Population of Development: Age range (therapeutic indication):

0-71 months (Developmental Disabilities)
Validated with children on the autistic spectrum, with cerebral palsy, receiving physical therapy for various diagNoses, and premature children and babies

Pediatric Population(s) in which COA has been used:

Mental Disorders; Nervous System Diseases; Congenital, Hereditary, and Neonatal Diseases and Abnormalities; Cardiovascular Disease ; Female Urogenital Diseases and Pregnancy Complications; Nutritional and Metabolic Diseases; Eye Diseases; Musculoskeletal Diseases; Neoplasms; Respiratory Tract Diseases; Digestive System Diseases; Virus Diseases; Otorhinolaryngologic Diseases; Pathological Conditions, Signs and Symptoms; Wounds and Injuries; Respiratory Tract Diseases

COA type:

Number of Items 249 tests (the number of tests administered is specific of each child, depending on the age and the level of development)

Mode of Administration:

Data Collection Mode:

Time for Completion: 45 to 60 minutes for the entire assessment. Approximately 20 to 30 minutes for gross motor or fine motor assessments, respectively.

Response Scales: 3-point verbal rating scale ranging from 0 "unable to perform", 1 "partial performance", 2 "correct performance"

Summary of Scoring:

Available scores:
3 composite scores (Sum of standard scores are presented as percentiles, standard scores, and age equivalents. Score ranges were not reported.)
Gross Motor Quotient
Fine Motor Quotient
Total Motor Quotient

Cut-Off score for children with or without fine motor: 16th percentile, child is considered to have fine motor problems
Cut-Off score at risk and pre-term infants: 16th percentile for gross motor skills in infants at the 4 month age level

Weighting:
No

Score Interpretation:
Higher score= Better developed motor abilities
