本研究利用人格五因子形容詞的概念，嘗試量化人格形容詞來探討人群之間性格的相似程度。本研究透過社團群體、人際群體以及情侶關係來驗證相似度。研究結果顯示在人際群體中，以經驗開放性為主要指標。在高度任務環境下的群體，以負責性為主要的指標。而情侶關係是以部分性格相似為主要指標。綜言之，研究結果解釋了群體個性的聚合，會按照群體所處的不同環境條件與需求背景，呈現出在特定五型分數上聚合較明顯的現象。
This research proposes a novel method to quantify the similarities among adjectives by utilizing the concept of Big Five model. This research verifies the proposed method through three types of group:social group, interpersonal group, and couple. The results reveal that
“openness to experience” is the indicator for the natural formation of an interpersonal group. Conscientiousness is the indicator for the formation of a task-oriented group. Couples mostly have at least one construct of similarity. In summary, result shows the cohesion of a group has various effects on particular constructs of Big Five model based on demands and environment.
