健身運動心理需求滿足感量表修訂之研究

目的：本研究之目的爲透過一系列量化研究程序來修訂一份具信、效度中文版本的健身運動心理需求滿足感量表。方法：參與者爲自來北、中、南地區有健身習慣的685位成年民眾（研究一：228人、研究二：229人、研究三爲228人），平均年齡爲40.0±10.16歲。所有參與者完成健身運動心理需求滿足感量表。研究者分別以探索性因素分析、驗證性因素分析和複核效化等方法進行資料分析。結果：在進行探索性因素分析後得到三個分量表，分別命名爲勝任感、自主性和關係感，解釋變異量爲80.44%，內部一致性係數分別爲.95、.96和.94。在進行驗證性因素分析後，由模式內在結構的適配評鑑結果顯示觀察變項與潛在變項皆具有良好的信度、聚合效度和區別效度。在進行複核效化的結果顯示模式健身運動心理需求滿足感量表具有穩定性。結論：本研究結果顯示量表具有良好信、效度及建構效度，建議後續研究利用本量表進行相關研究工作。

Purpose: to revise a reliable and valid scale of the Chinese-version through a series of quantitative research procedures to measure the psychological need satisfaction in exercise. Methods: The study sample consisted of 685 adults (228 for Phase I, 229 for Phase II, and 228 for Phase III) from the north, center and south of Taiwan with regular physical exercise habits (mean age was 40±10.16). The collected data were processed through exploratory factor analysis, confirmatory factor analysis and cross-validation analysis. Results: Exploratory factor analysis identified three subscales termed competence, autonomy and relatedness. The variance explained for the three subscales accounted for 80.44%, with corrected item-total correlations, .95, .96 and .94 for Subscale I, II and III, respectively. The confirmatory factor analysis found the whole model's fit indices satisfied observed and latent variables, which showed satisfactory reliability, convergent validity and discriminant validity. The cross-validation analysis further substantially supported the stability of the scale developed. Conclusion: The results indicated the scale revised had satisfactory reliability, validity and construct validity. Future research on related areas by using the current scale is recommended.
