目的:本研究之目的旨在建構一個整合性的身體意象假設模型,藉以檢驗媒體傳播效應、身體意象與運動參與程度等變項間之潛在關係。方法:研究對象是國內三所大學之636名女性學生(平均年齡20.11歲,標準差1.54歲),所使用的量表包括「媒體接觸量表」、「身體意象問卷」以及「運動參與程度量表」。結果:經結構方程模式分析結果顯示:(一)假設模型對於資料的適配度佳(χ^²/df=2.05、RMSEA=.04、NFI=.97、CFI=.99、SRMR=.02);(二)媒體傳播效應對於身體意象具有顯著的負向影響;(三)身體意象對於運動參與程度具有顯著的負向影響;(四)媒體傳播效應對於運動參與程度未具顯著影響。結論:根據上述結果,研究者建議體育教師與心輔同仁可以開設多元且合宜的瘦身減重課程,配合舉辦有益身心健康的體能性休閒活動,藉此灌輸學生關於身體意象方面的知識,佐以推廣從事規律運動所帶來的益處,以導正傳播媒體所傳達的偏差體型概念。研究者除對結果進行深入討論外,並將對未來研究提出具體建議。
Purpose: The purpose of this study was to examine a hypothesized model of the latent relationships among media broadcasting effect, body image, and exercise behavior. Methods: The participants consisted of 636 female students (mean age=20.11 years old, SD=1.54) from three domestic universities. The research instruments included ”media exposure scale”, ”body image inventory”, and ”exercise behavior scale”. Results: Using Structural Equation Modeling to analyze the data, the results revealed that: (1) the hypothesized model fit the data appropriately (χ^2/df=2.05, RMSEA=.04, NFI=.97, CFI=.99, SRMR=.02); (2) media broadcasting effect was found to be negatively predicted body image; (3) body image was found to be negatively predicted exercise behavior; (4) media broadcasting effect was not significantly related to exercise behavior. Conclusion: Based on the results above, the researchers suggested physical education teachers and school psychologists open suitable and diverse weight-control courses as well as provide sport-oriented extracurricular activities so as to enhance students' knowledge about body image and promote the benefits of regular exercise in an effort to correct the concept of body shape disturbance conveyed by the mass media. Recommendations for future research were further provided in the discussion.
