title: A brief motivational interview promotes internal motivation to donate blood among young adults with and without a prior donation history.
abstract: 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.
  
  
  
  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.
  
  
  
  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.
  
  
  
  A brief motivational interview may enhance donation intention and intrinsic motivation among both experienced donors and nondonors alike.
