“…However, during the intervention phases, the number of students observed entering the restroom to hand wash did not change. Interestingly, the behavior change techniques used in our pilot research have been previously shown to influence student hand hygiene (e.g., Surgeoner, Chapman, & Powell, 2009), the hand hygiene of food preparation staff (e.g., Geller, Eason, Phillips, & Pierson, 1980) as well as other important health behaviors (e.g., Berry, Geller, Calef, & Calef, 1992;Williams, Thyer, Bailey, & Harrison, 1989). However, university students in this cafeteria setting were not influenced by these traditional intervention techniques.…”
