目的：探討有氧舞蹈者體型滿意度及自我呈現動機在運動依賴的差異。方法：本研究為橫斷調查，自高雄市11間健身中心隨機選取參與者後，讓其填寫體型滿意度、自我呈現動機與運動依賴等量表，發出983份問卷，回收955份，有效樣本共927位，平均年齡36.17（SD=9.48）歲，男女各為205和722人。將資料以雙因子多變量變異數分析及Pearson相關分析處理。結果：（一）體型滿意度與自我呈現動機在持續性、耐受性及意圖影響差異達顯著水準，事後比較發現高低體型滿意度組之高自我呈現動機組得分高於低自我呈現動機組；低自我呈現動機組之高體型滿意度得分高於低體型滿意度。（二）體型滿意度在戒斷症狀、持續性、耐受性及活動削減差異達顯著水準，事後比較發現高體型滿意度得分高於低體型滿意度。（三）自我呈現動機對全部運動依賴構面主要效果達顯著水準，事後比較發現高自我呈現動機得分高於低自我呈現動機。（四）體型滿意度及自我呈現動機與運動依賴存在顯著正相關。結論：體型滿意度與自我呈現動機是影響運動依賴顯著的因子，參與有氧舞蹈目標若在管控體型以及發展形象，行為過量時有發生運動依賴的風險。

Purpose: This study aimed to compare the exercise dependence among aerobic dance participants with different levels of body satisfaction and self-presentation motivation. Methods: The study followed a cross-sectional design. Participants were randomly sampled from eleven fitness centers located in Kaohsiung who enrolled in the aerobic dance classes. After providing informed consents, participants were asked to share their opinions of body satisfaction, self-presentation motivation, and exercise dependence behaviors. A total of 983 questionnaires were distributed, and 955 questionnaires were returned with 927 valid samples. The average age of the participant was 36.17 (SD=9.48), including 205 male and 722 female participants. A two-way multivariate analysis of variance and Pearson's correlation analysis were adopted for data analysis. Results: (1) The patterns of continuance, tolerance, and intention effects were significant differences between different body satisfaction and self- presentation motivation. The post-hoc test shows that aerobic dance participants have high/low body satisfaction with a high self-presentation motivation score performed more positive on the aforementioned three variables than those who with a low self-presentation motivation. Also, the low self-presentation motivation with a high body satisfaction score performed more positive on the aforementioned three variables than those who with a low body satisfaction score. The patterns of withdrawal, continuance, tolerance, and reduction in other activities were significant differences between different body satisfaction. The post-hoc test shows that aerobic dance participants with a high body satisfaction score performed more positive on the aforementioned three variables than those who with a low body satisfaction score. (3) Aerobic dance participants with high self-presentation motivation performed more positive on the behavior in all dimensions of exercise dependence than those who with low self-presentation motivation. (4) There are significant positive correlations between body satisfaction, self-presentation motivation, and exercise dependence. Conclusions: Body satisfaction and self-presentation motivation are two important factors in explaining exercise dependence. Furthermore, when people who participating aerobics exercise with the goal of "weight control" and "self-image development" and having the behavior of excessive exercise could take the risk of being exercise dependence.
