BACKGROUND Recruitment and retention of first‐time and repeat donors is essential to maintain a stable blood supply. Recent evidence has shown that promoting internal motivation may be an effective strategy to enhance donation behavior. We tested the efficacy of an in‐person motivational interview at increasing internal motivation and intention to donate. STUDY DESIGN AND METHODS A sample of 219 donors and nondonors (69.4% female; mean ± SD age, 19.2 ± 1.1 years; 52.1% nondonors) were randomly assigned to either a motivational or a knowledge interview. Immediately before and after the interview participants completed a measure of donation intention and the Blood Donor Identity Survey, which is a multidimensional measure of donor motivation. RESULTS A latent profile analysis revealed three distinct latent classes, which were identified as low internal motivation, mid internal motivation, and high internal motivation. Comparison of change in latent class from pre‐ to postinterview revealed that a higher proportion of participants in the motivational interview group moved to a more internally motivated class compared to the knowledge interview group (i.e., 34% vs. 4%, respectively). Further, relative to the knowledge interview group, participants in the motivational interview group reported greater increases in intention to donate. CONCLUSION A brief motivational interview may enhance donation intention and intrinsic motivation among both experienced donors and nondonors alike.
