目的：本研究旨在探討舞蹈系女學生的身體質量指數、身體形象、體重壓力對於社會體型焦慮之假設模型的驗證。方法：以200名舞蹈系女學生為研究對象，檢測工具為個人基本資料問卷、身體形象量表、體重壓力量表、社會體型焦慮量表，並以結構方程模式(SEM)進行假設模式之驗證。結果：身體質量指數不會顯著影響體重壓力；身體質量指數會顯著影響身體形象；身體質量指數會顯著影響社會體型焦慮；體重壓力不會顯著影響身體形象；體重壓力會顯著影響社會體型焦慮；身體形象會顯著影響社會體型焦慮。結論：除引導她們正確的維持體態之外，最初選才也是要嚴格控制。未來探討舞者社會體型焦慮議題時，可結合「參與動機」，驗證是否較高社會體型焦慮會影響參與動機。此外，亦可擴大至男性，因追求美好身形已不再是女性的專利。

Purpose: The study was designed to examine the hypothetic model of body mass index, body image, and weight pressure in predicting social physique anxiety in female students from dance department. Methods: Two hundred female students of dance department were recruited as participants. Demographic data questionnaire, body image scale, weight pressure scale, and social physique anxiety scale were used to obtain data, and structural equation modeling (SEM) was used to examine the hypothetic model. Results: Body mass index didn't significantly affect weight pressure, while had great impact on body image and social physique anxiety. Weight pressure didn't significantly affect body image, but did significantly affect social physique anxiety. Body image significantly affected social physique anxiety. Conclusions: Controlling the recruiting process strictly in the early phase is also important besides guiding the female students to keep fit in correct ways. When conducting research about dancers' social physique anxiety in the future, it's worthwhile to include the "participating motivation" variable to investigate whether social physique anxiety would affect participating motivation. Besides, male dancers can be future participants, because pursuing ideal figure is no longer exclusive right for females only.
