“…First, despite that early studies suggest a unidimensional construct of volunteer motivation (e.g., Cnaan and Goldberg-Glen 1991), extensive research has identified the critical role different motivations of volunteering play in shaping individuals' perceptions, attitudes, and behaviors toward volunteer work (Cialdini et al 1987;Mesch et al 1998;Phillips and Phillips 2011;Smith 1981;Stukas et al 2016). For instance, other-oriented, altruistic motives of volunteering are positively related to satisfaction and intentions to continue (Stukas et al 2016), participation in corporate volunteering (Sekar and Dyaram 2017), and commitment (Veludo- de-Oliveira et al 2015), while selforiented motives are negatively related to such concepts. Second, another stream of research has taken a functionalist perspective in exploring the role of volunteer motivation, suggesting that different motives may appeal to different individuals through different functional mechanisms such as value, understanding, social, career, protective, and enhancement (Clary et al 1998;Snyder et al 2000).…”
