The PDMS-2 was developed in 2000 as an updated version of the original Peabody Developmental Motor Scales (PDMS), first published in 1983. Designed for children from birth to 6 years, it was created to provide a comprehensive assessment of motor skills. The second edition introduced enhanced norms, improved psychometric properties, and expanded age ranges. Published by Pro-Ed, the PDMS-2 reflects advancements in motor development research and clinical practice, ensuring accurate and reliable evaluations.
Structure and Components of PDMS-2
The PDMS-2 includes six subtests evaluating gross and fine motor skills in children aged birth to 6 years, providing a comprehensive assessment of motor development in early childhood.
2.1 Subtests and Categories
The PDMS-2 consists of six subtests: Reflexes, Stationary, Locomotion, Object Manipulation, Grasping, and Visual-Motor Integration. These categories assess various motor skills, from basic reflexes to complex movements, in children aged birth to 6 years. Each subtest evaluates specific abilities, providing a detailed understanding of a child’s motor development and identifying potential delays or difficulties in coordination and dexterity.
2.2 Assessment of Gross and Fine Motor Skills
The PDMS-2 evaluates both gross motor skills, such as walking, running, and balance, and fine motor skills, including grasping, drawing, and object manipulation. Specific subtests like Stationary and Locomotion target gross motor abilities, while Grasping and Object Manipulation focus on fine motor precision. This dual assessment provides a comprehensive understanding of a child’s motor development, helping to identify delays and track progress over time.

This process ensures the tool’s validity and applicability for assessing motor skills in various clinical and educational settings nationwide.
3.2 Interpretation of Scores
The PDMS-2 provides standardized scores based on national norms, including percentiles, standard scores, and age equivalents. These scores help identify if a child’s motor skills are typical or delayed. Clinicians interpret scores to determine motor proficiency and guide intervention planning. The tool offers clear criteria for classifying motor skill levels, ensuring accurate assessment and informed decision-making for children’s developmental needs.
Administration and Scoring
The PDMS-2 requires trained examiners to administer and score tests, involving observation of motor tasks and application of standardized scoring criteria to ensure reliable results.
4.1 Examiner Requirements and Training
The administration of PDMS-2 requires trained professionals with expertise in motor development. Examiners must thoroughly understand the assessment manual and undergo specific training to ensure accurate and reliable testing. Proper training includes learning to observe and score motor tasks effectively, as well as interpreting results based on standardized criteria. This ensures consistency and validity in evaluating children’s motor skills across different settings.
4.2 Scoring Criteria and Reliability
The PDMS-2 employs a standardized scoring system to ensure reliable results. Each task is scored based on specific criteria, with clear guidelines to minimize examiner bias. High inter-rater reliability has been reported, indicating consistency across different assessors. This robust scoring system supports accurate identification of motor delays and progress monitoring, making it a dependable tool for both clinical and research applications in pediatric motor assessment.
