Purpose

The primary aim of the Δέσμη Μέτρησης Κινητικής Ικανότητας [ΔΜΚΙ-46] is to assess children aged 4.5 to 14.5 years. It is intended to serve as a useful “tool” for educators, researchers, and psychologists conducting clinical studies. Through this, they can evaluate children’s motor skills, design exercise programs, assess dysfunctions related to the improper functioning of their motor system, and detect developmental disturbances early on.

Key Features

The ΔΜΚΙ-46 consists of 46 diagnostic tests, categorized into eight categories, and was developed by Bruininks in 1978. The raw scores are “transformed” into “classes,” based on a comprehensive index that expresses motor efficiency. Additionally, a shorter version of the test with 14 items is available.

Scoring

The scoring of the ΔΜΚΙ-46 varies, either by applying a scale or assigning whole-number scores. These scores are then compared with tables derived from the test’s calibration phase. The final score is the sum of these values, with a higher score corresponding to better performance.

Validity and Reliability

The validity of the ΔΜΚΙ-46 is supported by research related to motor development concerning its structure. Validity checks were conducted in three ways: Correlation of performance scores with age. Evaluation of internal consistency across the sections. Assessment of the content structure and the relationship between diagnostic tests.
In terms of reliability, the test showed coefficient values ranging from low (r = 0.68) to moderate (r = 0.88). For all sections, indices greater than 0.80 were recorded. The internal consistency reliability index (Cronbach’s α) is 0.87 for children aged 5 to 8 years in Greece.
