Any scoring system for a sports event is expected to be fair and justify. With a fair and justified scoring system, some participants win the victory and gain respect, whereas, those who lose the game are sincerely convinced. Cheerleading competitions have been held for years in Taiwan and the scoring system has also been updated several times. As for the cheerleading competition organized by Chinese Taipei University Sports Federation in 2009, the scoring criteria include areas of techniques, gymnastics, and flow of routine. The purpose of this study was to help technical judges not score areas of gymnastics and flow of routine, in order to avoid biased evaluation and multiple point deduction. The research method utilized in the study was experimental design, and the regulatory focus theory was included. One hundred twenty-three college students, who were participated in cheerleading competitions were randomly assigned into promotion focus (2 groups) × performance (3 groups) groups. The results reported that hints have impacts on participants' choosing regulatory focus. When having promotion orientation resulted from hints, participants were less likely to achieve biased scores. Furthermore, study results conclude that without hints judges in a cheerleading competition were more likely to be concerned with promotion focus. Also, they were more likely to compare the performance of various teams (rather than scoring the specific criterion) and be biased (additional points or multiple point deduction). However, when the regulatory focus theory was adopted (i.e., judges are given hints), judges were more likely to have defensive focus when being asked to request participants to write down the past and current responsibility and obligations. In addition, the validity of scores given by judges with defensive focus was tested and the rationality was proved. These findings may help to improve the scoring system of cheerleading and provide future references to scoring system for other sports events. This study results also showed the fair and justified scoring system in cheerleading competitions.
