本研究乃國內首度針對大專院校競技啦啦隊員進行大規模調查，據以檢視雙元熱情模式對正負向行為後果－得獎績效與運動傷害之影響，並建立雙元熱情－時間變數－行為後果的路徑關係。本研究針對2008年參加全國大專院校啦啦隊錦標賽之參賽隊員，施以問卷調查，獲有效樣本498份，並以描述性統計、t檢定、線性結構方程式分析資料。結果確認雙元熱情的兩構面－調和型熱情與偏執型熱情，以及雙元熱情對正向得獎績效與負向運動傷害的直接與間接效果。結論：一、大專院校啦啦隊員普遍抱持高度熱情參與啦啦隊活動，且擁有偏執型熱情者佔近2/3的高比例。二、國內曾因練習受傷的大專院校啦啦隊員比例近八成五，凸顯啦啦隊運動傷害之嚴重性。三、雙元熱情越高，則得獎績效越好，且遭致的運動傷害也越多；其中偏執型熱情的影響力大於調和型熱情。四、除了偏執型熱情對得獎績效具正向直接效果之外，其餘路徑皆須透過參與資歷與投注時間，來間接影響得獎績效與運動傷害，凸顯時間變數的中介角色。

This was the first empirical study to survey the impact of dualistic passions towards positive behavioral outcomes-award performance and negative outcomes-sport injuries among Taiwan college cheerleaders, and so as to explore the path from dualistic passion through time variables to positive and negative outcomes. Among the 498 valid samples from participants in the 2008 National College Cheerleader Championship, using descriptive statistics, t-test, ANOVA as well as SEM to analyze the data, the result confirmed the two subdimensions, namely harmonious passion and obsessive passion, as well as the direct and indirect effect of a dualistic model of passion-time relative variables- positive/negative outcomes. This research obtained the following conclusions: 1. College cheerleaders generally possess high levels of passion with almost 2/3 of participants displaying obsessive passion. 2. Serious sports injuries are light with almost 85% of participants used to getting hurt during practice. 3. The higher the harmonious and obsessive passion, the better the participants' award performance in the competition and the higher the likelihood of injury. Obsessive passion was shown to have a stronger influence than harmonious passion. 4. With obsessive passion the only one to show a direct path of effect to a participant's award performance, all other paths go through mediators of time variables, e.g. seniority and dedicated time, to indirectly affect the two outcomes.
