“…From this, sport nostalgia is broken down into four dimensions, namely, experience (i.e., nostalgic feelings related to positive memories of the experience itself, sights, and environments in which sport takes place), socialization (i.e., nostalgia associated with past relationships with others at sporting events), personal identity (i.e., nostalgic feelings toward one's identity focusing on roles in sport), and group identity (i.e., nostalgia related to an individual's group experience, culture, and norm) [ 10 ]. Based on the four dimensions, researchers have developed nostalgia scales [ 22∗∗ , 23 , 24 , 25 ] and examined the various roles of nostalgia in sport and leisure [e.g., 18 , 26∗ , 27 , 28 , 29∗ , 30 , 31 ]. In other words, the multidimensional approach to nostalgia allowed researchers to investigate how it functions in sport and leisure.…”
