香港中學生拾放豆袋測試的效度及信度

Abstract

LANGUAGE NOTE | Document text in English; abstract also in Chinese.

The test most often recommended for measuring upper body strength and endurance is the pull-ups which has often been criticized because of the large number of zero scores. In the last academic school year, twelve secondary schools under the Po Leung Kuk group administered the Bailey Bridge Test for measuring upper body strength and endurance in their own physical fitness test battery. The purpose of this study was to investigate the validity and reliability of the Bailey Bridge Test for secondary school students. A total of 1,906 secondary school students, aged 13-19, from 4 schools, participated in the study. Criterion validity was assessed by correlating Bailey Bridge Test with bent-knee push-up and hand grip strength. A sample of subjects were tested on two different days on Bailey Bridge Test to establish stability reliability. To conclude, the Bailey Bridge test shows unacceptable validity with barely acceptable reliability.

一般用來測試上肢肌力的引體向上方法，受試者很常會取得零分而影響教師對學生的評估。去年本港保良局屬下十二間中學，製定出一套體適能測試方案，並採用了拾放豆袋測試來量度學生的上肢肌力。本文目的是評審拾放豆袋測試的效度和信度。共有1,906位13至14歲的中學生參與本研究，以屈膝掌上壓及手握力測試的相關系數作爲效標關聯效度的指標；再測法則用來計算信度。研究結果顯示拾放豆袋測試的效度未能被接受，信度也偏低。
