The testers in this research are the college volleyball athletes ?218 people in total? who participated in the college volleyball league match of the 97th academic year. According to the database that the writer has been collected through the surveys and the analysis of one-way MANOVA, Pearson product-moment correlation, and other related statistics methods. The results show as followed. 1.In the aspect of the Coach?s Positive Sense Leadership Behavior ?for example, training and instruction behavior, democratic behavior, social support behavior, award and praising behavior?, the ego-orientated college volleyball athletes have better performance than the task-orientated ones. In the aspect of the Coach?s Negative Sense Leadership Behavior, on the contrary, ego-orientated college volleyball athletes perform better than the ego-orientated ones. 2.The relationship between the Task Orientation and most of the Coach?s Positive Leadership Behavior is positive; it can effectively predict the ?democratic behavior? and ?award and praising behavior? in leadership behaviors. On the contrary, it shows negative or none relationship between the Ego Orientation and most of the Coach?s Positive Leadership Behavior, and the positive relationship between the Ego Orientation and the Coach?s Negative Leadership Behavior. The results above not only support the Achievement Goad Theory and the assumptions in this research, but also conform to the previous research results.
