This study examined the motives for different expressions of humor. University students (n=286) completed a questionnaire regarding motives for three types of humor expressions: aggressive humor, self-disparaging humor, and playful humor. Exploratory and confirmatory factor analyses indicated that the motives for the expressions of humor could be classified into five types: relationship construction, transmitting dissatisfaction, supporting others, managing self-impression, or supporting self. ANOVA was conducted to examine differences in the strengths of the motives among the three types of humor expressions. The results indicated that the motive for transmitting dissatisfaction was stronger in aggressive humor expressions than in the two other types of humor expressions. On the other hand, the motive for supporting others was weaker in aggressive humor expressions than in the two other types of humor expressions. Moreover, the motive for supporting self was stronger in self-disparaging humor expression than in aggressive humor expression.
