Behavioral community intervention to reduce the risk of skin cancer.

Researchers ran a summer-long program at two public pools. They picked teen lifeguards to model hat and sunscreen use, posted daily goals, and held a weekly raffle for families who signed a sun-safe pledge.

Kids and adults swam as usual. The team simply watched how many people wore shirts, hats, or used sunscreen before and after the program.

Children tripled their use of hats, shirts, and sunscreen. Adults nearly doubled their use. Lifeguards, who started with the lowest rates, showed the biggest jump.

The gains held for the rest of the summer with no extra staff time.

Ellingsen et al. (2014) also taught safety skills in the community, but they used short computer lessons plus quick in-person drills. Both studies show brief, low-cost programs can change real-world health behavior.

Renne et al. (1976) taught sick children to use asthma machines with scripts and praise. D et al. used peer models and raffle tickets instead of direct teaching, yet both got strong skill gains.

Sofronoff et al. (2011) ran two short group seminars for parents. D et al. ran one brief pool campaign. Both cut adult problem behavior—sunburn risk versus harsh parenting—showing that simple group packages can work across very different goals.

You can copy this at any community site. Pick popular teens to model the target behavior, post a daily count everyone can see, and add a small raffle. No extra staff, no extra cost, and you still triple healthy habits.
