We often cheer for others in our daily lives, not only for our favorite celebrities but also for our family, friends, and even strangers. In actual cheering situations, some people cheer enthusiastically while others are less interested in cheering, indicating that there are individual differences in cheering tendencies. This study developed a cheering tendency scale to examine the factors of willingness to cheer for others. The exploratory factor analysis showed that the cheering tendency includes the following four factors: a) interest in a likable person, b) attunement to other observers, c) promoting a positive situation of others, and d) overcoming a negative situation of others. The result of Cronbach’s 𝛼 coefficient and correlation analysis with the related scales showed sufficient reliability and validity of our developed scale. Moreover, we conducted a cluster analysis, with the result that the respondents could be classified into the following four clusters: a) active cheering group, b) self-sufficient cheering group, c) passive cheering group, and d) non-cheering group. We conclude that the developed scale is sufficiently reliable and valid to characterize cheering behavior, personality traits, and the tendency to have a “fave” by cluster, which can be used for further cognitive studies.
