Table 2: Previous studies on older adults’ motivations for using senior citizen centers. care services [63, 64]. These findings provide theoretical evidence supporting the hypothesis that older adults' motivations for using senior citizen centers differ based on the type of eldercare system. Extensive research has been conducted on Busan, reflecting its social and economic characteristics. Busan has a significantly higher aging rate than other urban areas in Korea, engendering a surging demand for senior welfare services [16, 17, 18]. Most studies on senior citizen centers in Busan have focused on the efficiency of facility operations, user satisfaction, and physical accessibility [14, 19, 20]. Consequently, research on the motivations of senior citizen center users concerning social access and mental health is lacking [21]. Therefore, based on the previous studies listed in Table 2, this study aims to empirically demonstrate the relationship between older adults' motivations for using senior citizen centers and the type of eldercare system, focusing on the district of Yeongdo-gu in Busan.
