“…Different studies worldwide have underlined the need to increase the number of blood donors among undergraduates (De Los Santos and Firmo, 2019). However, despite growing interest in the issue, especially among health sciences students (Cicolini and et al, 2019;Dean et al, 2018;Gomes and et al, 2019), most research has been conducted outside Europe, and therefore, the majority of available evidence comes from these sociocultural contexts (Eshak et al, 2019;Gazibara et al, 2015). In recent years, Portuguese (Gomes and et al, 2019) and Italian (Alfieri, 2017;Cicolini and et al, 2019;Zito et al, 2012) researchers have worked with younger students, highlighting the importance of putting good attitudes into practice even though the voluntary donation system is already considered to be working (De Los Santos and Firmo, 2019;WHO, 2010).…”
