Buckle-Up Promise Cards

Geller, E. S., and Lehman, G. R. (1991). The Buckle-up Promise Card A Versatile Intervention for Large-Scale Behavior Change. Journal of Applied Behavior Analysis, 24, 91-94. 

My students and I have also distributed "Buckle-Up Promise Cards" during church services (Talton, 1984), throughout a large university campus (Geller et al., 1989), and at the Norfolk Naval Base (Kalsher et al., 1989). In every case, a significant number of pledge-card signers increased their use of safety belts after their initial commitment behavior.
