本研究的目的是：一、探討身體活動自我呈現自信心和體型滿意度對舞蹈系學生之減重意圖的預測情形；二、探討身體活動自我呈現自信心和體型滿意度對舞蹈系學生之飲食態度的預測情形。本研究以124位台北體院舞蹈系、台北藝術大學舞蹈系、台灣體院舞蹈系女大學生為研究對象。研究工具為身體活動自我呈現自信心量表、體型滿意度量表、減重意圖量尺及飲食態度量表。所蒐集的資料以多元逐步迴歸分析進行資料處理。本研究所得結果如下：一、「體重的控制」和「能力的展現」兩個因素對「減重意圖」的解釋變異量達11.7%。二、「身體吸引力」、「體重的控制」和「能力的展現」三個因素對「飲食態度」的解釋變異量達16.9%。顯示身體活動自我呈現自信心可以有效預測舞蹈系學生的減重意圖與飲食態度。

The purposes of this study were: 1. to explore the predictions of self-presentation confidence in physical activity and physique satisfaction on college students' intentions of weight reduction; 2. to explore the predictions of self-presentation confidence in physical activity and physique satisfaction on college students' eating attitudes. There were 124 female participants drawn from TPEC, TNUA, NTCPE. The research tools were Self-Presentation Confidence in Physical Activity Inventory, Physique Satisfaction Inventory, Intentions of Weight Reduction Scale and EAT-26. The collected data were analyzed by multiple stepwise regression analysis. The findings were as the following: 1. ”weight control” and ”ability presentation” could effectively predicted ”intentions of weight reduction” (11.7%). 2. ”physical attraction”, ”weight control” and ”ability presentation” could effectively predicted ”eating attitudes” (16.9%). Finally, the results were discussed, and the suggestions of practical application and future research were offered. That showed self-presentation confidence in physical activity could effectively predict weight reduction and eating attitudes in college student dancers.
