目的:本研究是利用兩組獨立樣本以探索性和驗證性因素分析檢定運動能力內隱理論量表的因素效度,另外,本研究也檢定不同運動能力理論與內在動機和無動機的關係。方法:本研究徵募535名運動選手為研究對象,主要的統計方法是探索性和驗證性的因素分析以及簡單相關分析。結果:發現運動能力內隱理論量表具有良好的因素效度、幅合效度、區別效度及組合信度;本質理論與無動機呈正向關係,與內在動機呈負向關係,增進理論與內在動機呈正向關係,與無動機呈負向關係。結論:運動能力內隱理論量表是一份具有心理計量品質的問卷,適用於測量運動選手在不同運動能力內隱理論上的採用情形。
Purpose: This study aimed to test validity of implicit theories of sport ability scale (ITAAS) via two independent samples using exploratory and confirmatory factor analyses. Also, this study was to examine the relations of entity theory and incremental theory to intrinsic motivation and amotivation. Methods: Five hundred thirty five Taiwanese sport athletes were recruited. Main analyses were explore and confirmatory factor analyses and simple correlation analysis. Results: The results of exploratory and confirmatory factor analyses showed that the hypothesized model of ITAAS had acceptable factorial validity, discriminant validity, convergent validity, and construct reliability. The correlational results indicated that entity theory positively related to amotivation and negatively to intrinsic motivation. For incremental theory, it had the positive relation to intrinsic motivation and the negative relation to amotivation. Conclusion: According to these results, ITAAS demonstrated a good psychometric property and was suitable to measure variation of athletes in the adopting different sport ability theories.
