Reliability and validity of the test of gross motor development-II in Korean preschool children: applying AHP.

Kim et al. (2014) · Research in developmental disabilities 2014
★ The Verdict

TGMD-II keeps its reliability and validity when used with Korean preschoolers.

✓ Read this if BCBAs serving Korean preschoolers who need baseline or progress motor data.
✗ Skip if Clinicians who only treat school-age or non-Korean populations.

01Research in Context

01

What this study did

Researchers checked if the TGMD-II test works well for Korean preschoolers.

They gave the gross-motor test to 121 children without disabilities.

One trained tester scored every child to see if results stayed the same.

02

What they found

The scores were steady and matched what the test promises.

The study says the Korean version is ready for preschool use.

03

How this fits with other research

Costa et al. (2017) did the same kind of job with a Chinese social-skills scale.

Both papers show that translated tests can keep their strength in East-Asian kids.

Westendorp et al. (2014) looked at gross-motor growth in older children with learning disorders.

They found big delays, while Chung-Il et al. saw typical scores in healthy preschoolers.

The two studies do not clash—they just map different groups and ages.

04

Why it matters

If you work with Korean preschoolers, you can trust TGMD-II scores to spot motor needs.

Use the test at intake, then track change every few months.

A clear motor number helps you write goals and show parents real progress.

03Original abstract

The Test of Gross Motor Development-II (TGMD-II) is a frequently used assessment tool for measuring motor ability. The purpose of this study is to investigate the reliability and validity of TGMD-II's weighting scores (by comparing pre-weighted TGMD-II scores with post ones) as well as examine applicability of the TGMD-II on Korean preschool children. A total of 121 Korean children (three kindergartens) participated in this study. There were 65 preschoolers who were 5-years-old (37 boys and 28 girls) and 56 preschoolers who were 6-years-old (34 boys and 22 girls). For internal consistency, reliability, and construct validity, only one researcher evaluated all of the children using the TGMD-II in the following areas: running; galloping; sliding; hopping; leaping; horizontal jumping; overhand throwing; underhand rolling; striking a stationary ball; stationary dribbling; kicking; and catching. For concurrent validity, the evaluator measured physical fitness (strength, flexibility, power, agility, endurance, and balance). The key findings were as follows: first, the reliability coefficient and the validity coefficient between pre-weighted and post-weighted TGMD-II scores were quite similar. Second, the research showed adequate reliability and validity of the TGMD-II for Korean preschool children. The TGMD-II is a proper instrument to test Korean children's motor development. Yet, applying relative weighting on the TGMD-II should be a point of consideration.
