| As blood supply and demand are in a precarious balance, we need to constantly recruit new donors to replace deferred and withdrawn donors. Several studies revealed that donation intentions are influenced by: (1) affective attitude, (2) personal, (3) subjective, and (4) descriptive norms, and (5) self-efficacy. A content analysis on the recruitment leaflets showed that affective attitude, personal norms, and self-efficacy were hardly targeted. Adding this information needs to increase effectiveness of the leaflets. To target subjective and descriptive norms we studied the willingness of donors to engage in recruitment by discussing their blood donation experiences with family and friends. As the majority of donors were positive, we want to compare different strategies to ask donors to engage in recruitment. |
