This subtest includes tasks like picking up small beads, using tweezers, and drawing lines and shapes. The Visual-Motor Integration subtest assesses the coordination between visual perception and motor skills, evaluating a child’s ability to copy shapes and patterns, draw lines, and complete puzzles. This subtest is crucial for tasks like writing, drawing, and building, which require the integration of visual information with fine motor control.

These subtests provide a comprehensive evaluation of a child’s fine motor development, encompassing essential skills for self-care, play, and academic success. They are particularly valuable for identifying potential delays or difficulties in areas like hand-eye coordination, manipulation skills, and visual-motor integration, which can impact a child’s ability to perform everyday tasks and participate in various activities.

Administration and Scoring

The PDMS-2 is administered individually to children, typically in a quiet and comfortable setting. The examiner presents the child with a series of tasks, observing their performance and recording their responses. The tasks are presented in a standardized manner, ensuring consistency across administrations. Each task is scored based on the child’s ability to complete it successfully, with specific criteria outlined in the examiner’s manual. Scores are then converted into standard scores, allowing for comparison to a normative sample of children of the same age.

The PDMS-2 includes detailed guidelines for administering the test, ensuring that the examiner understands the proper procedures and scoring criteria. The manual also provides detailed instructions for interpreting the results, allowing the examiner to draw meaningful conclusions about the child’s motor development. The scoring system is designed to be user-friendly, making it easy for examiners to record and interpret the child’s performance.

Interpreting Results

The PDMS-2 provides a comprehensive assessment of a child’s motor skills, offering valuable insights into their developmental progress.
