Table 1

Samples of the use of theory of planned behavior to study the intention of the students to perform blood donation, showing the sample and the main results.

Sample	Results	Reference
Students at a public higher learning institution in Malaysia	The results showed that knowledge that the more blood they donate, the more lives will be saved influences the students’ intention to blood donation	[18]
Private higher education students, Jimma town, Oromia, Ethiopia	Blood donation intentions are mainly determined by perceived barriers, subjective norms, and the attitude of respondents toward voluntary blood donation	[19]
Undergraduate students at the University of Ulster, Coleraine	The results provided strong support for the role of self-efficacy as a major determinant of blood donation intention	[20]
Medical students in Pakistan	The results indicated that perceived behavioral control, anticipated regret, and attitude were the most influential factors in determining intention of blood donation	[16]
University students, 18 years or older, since this is the minimum age necessary to give blood	The results indicate that self-efficacy is the construct with the greatest influence on the intention to donate blood, followed by attitude, with moral norm also having a high indirect influence through attitude	[21]
Undergraduate students at College of Health Sciences in Northeast Portugal	The results showed that the motivations of “be a civic duty” had a significant impact on donor status	[17]
