目的:利用多層面Rasch模式編製桌球反手擰球技術效標參照測驗。方法:研究對象以40位競技選手,組別分為精熟組23位、非精熟組17位,實施桌球反手擰球技術效標參照測驗,以FACETS程式估計選手、評分者、試做次數和試題等四個層面的測驗。結果:測驗資料適合Rasch模式;效標參照評量的分界分數在能力5.69邏輯子(logit),其介於原始分數422分和421分之間,以及效度係數0.75,信度的一致性比率0.88、柯恆kappa係數0.75和修正kappa係數0.75。結論:桌球反手擰球技術效標參照測驗具有良好的測驗品質,能鑑別競技選手反手擰球技術的精熟。
Purpose: The objective for this study was to construct of criterion-referenced test for backhand twist skills in table tennis using many-facet Rasch measurement model. Methods: 40 athletes were selected as the study subjects and was separated to two groups: 23 of them in Masters and 17 in Non-masters. The backhand twist technique criterion-referenced tests were applied to all of the subjects. The athletes, raters, trials and items were evaluated using many-facet Rasch measurement model. Results: The test data were fitted for Rasch model; The ability of cut-off score for criterion of validity reference test was 5.685 logit that corresponds to the original score between 422 and 421, and the validity coefficient was 0.75. The reliabilities of the agreement proportion was 0.88, the Cohen kappa was 0.75 and the modified kappa was 0.75. Conclusion: The criterion-referenced test for backhand twist skills in table tennis did generate good quality test results, and can be used to distinguish the master of backhand twist skills in athletes.
