Analysis and Validation of German Körperkoordinationtest für Kinder (KTK)

Objective: To verify the reliability and validity of German Körperkoordinationtest für Kinder (KTK) in the fundamental movement skills test of Chinese primary school students. Methods: 145 grades 1-5 students (age: 8.98±1.48 years old) from a primary school in Shanghai were selected as test subjects, and KTK and the American Gross Motor Development Test (TGMD) were used to test students' fundamental movement skills. Statistical test for validity. Results: The average KTK score of primary school students was 178.20±41.68, and the score increased with grades (F=11.94, P<0.001). The ICC in the test-retest reliability is between 0.966 and 0.992; the Cronbach's alpha coefficient in the internal consistency reliability is 0.820; the factor analysis model is well fitted in the construct validity (x²/df=0.036, RMSEA=0.001, AGFI=0.999); there was a moderate correlation between the concurrent validity and the TGMD total score (r=0.639, P<0.001). Conclusion: KTK has good reliability and validity in the fundamental movement skills test of Chinese primary school students, and it can be used as an effective evaluation tool for the development of fundamental movement skills of primary school students.
