Psychological outcomes achieved by university students as a result of club activities were investigated, and club activities were classified in relation to organizational traits. University students (n=459) participated in Study 1 and (n=193) participated in Study 2. The results indicated that psychological outcomes could be classified into three categories: adjusting to the group, practicing, and growth through events. Adjusting to the group was related to events that cultivated personal exchanges, practicing was related to events that completed practice, and growth through events was related to events associated with facing the self. Moreover, psychological outcomes were related to organizational traits of openness and group formality. Based on these findings, suggestions for achieving efficient group management are discussed.
