目的：本研究目的在編製發展2X2尚年級學重健身運動動機氣候量表(Motivational Climate Scale for Children Exercise,簡稱2X2 MCSCE)，以成就目標理論爲架構，兩階段
研究抽取臺中市國民小學五、六年級1202名學生爲有效樣本。方法：統計分析包含項目 分析、探索式與驗證式因素分析、多群組分析等。結果：結果顯示，量表包含4個因素， 精熟趨近、精熟逃避、表現趨近、表現逃避，共計16題，且此量表有良好信效度及測量 不變性，部分適合度指標未達標準。結論：量表適用於高年級學童健身運動動機氣候的測 量，未來可持續修正本量表。

Purpose: The purpose of the present study was to develop the 2X2 Motivational Climate Scale for Children Exercise derived from achievement goal theory. A total number of effective sample 1202 Taichung County elementary school fifth and sixth grade students were recruited from two data collection phases. Methods: The statistical analyses included exploratory factor analysis, confirmatory factor analysis, as well as multi-group analysis. Results: The results revealed that the 2X 2 Motivational Climate Scale for Children Exercise contained four subscales, including “approach mastery,” “avoidance mastery,” “approach performance,” and “avoidance performance, with a total of 16 items. In addition, the scale demonstrated satisfactory reliability, validity and measurement invariance, but a few fit measures didn’t reach the standards. Conclusion: The scale is a sound instrument for use in measuring children exercise motivational climate, and research endeavors may keep revising it in the future.
