“…First, the intrinsic motivation of students who participated in overseas volunteer programs was positively associated with their general altruism (t = 5.090**, p < .01), and positively associated with their bridge social capital (t = 4.352**, p < .01), thus supporting H1 and H2, which is consistent with Kroll and Tantardini (2019). Second, addressing H3 and H4, the learning stimulation of students who participated in overseas volunteer programs is positively associated with their general altruism (t = 2.235*, p < .05), and is positively associated with the bridging social capital of the volunteers (t = 7.599****, p < .01), which is consistent with earlier findings (Hu et al, 2016;Zhou et al, 2020). Third, the general altruism of students who participated in overseas volunteer programs is positively associated with the volunteers' culture sharing intention (t = 5.063**, p < .05); compared with Saide et al (2019), the general altruism and culture sharing intention of the volunteering students are closely related, supporting H5, and the bridging social capital of students who participated in overseas volunteer programs is positively associated with their culture-sharing intention (t = 5.138**, p < .05), supporting H6.…”
