Description

The TGMD-3 has two subtests. The first subtest, Locomotor, measures the gross motor skills that require fluid, coordinated movements of the body as the child moves in one direction or another. The second subtest, Ball Skills, measures the gross motor skills that demonstrate efficient throwing, striking, and catching movements. The TGMD-3 provides an overall composite (Gross Motor). The two subtest scaled scores are combined to form the Gross Motor composite. The Examiner’s Manual discusses the test’s theoretical and research-based foundation, item development, standardization, administration and scoring procedures, normative tables, and guidelines for using and interpreting the test’s results.

The average coefficient alpha is .88 for the Locomotor subtest and .89 for the Ball Skills subtest, and is .93 for the composite. New validity studies demonstrate the test’s ability to differentiate children with cognitive impairments and autism spectrum disorder from typically developing children. For the cognitive impairment sample, a Gross Motor Index cutoff score of 90 resulted in a sensitivity of .71, a specificity of .91, and a receiver operating characteristic/area under the curve of .87. For the autism spectrum disorder sample, a Gross Motor Index cutoff score of 85 resulted in a sensitivity of .76, a specificity of .91, and a receiver operating characteristic/area under the curve of .86.
