Randomized Controlled Trial
A cluster randomized trial of sun protection at elementary schools. Results from year 2.
Elementary schools are one potential venue for sun protection interventions that reduce childhood sun exposure. ⋯ This intervention increased use of hats at school through Year 2 but had no measurable effect on skin pigmentation or nevi. Whether school-based interventions can ultimately prevent skin cancer is uncertain.

Randomized Controlled Trial
Efficacy of a weight-loss website based on positive deviance. A randomized trial.
Web-based interventions for weight control could promote more-widespread dissemination of weight-loss opportunities; however, they remain limited in effectiveness. Incorporating weight-control practices used by individuals with long-term weight-loss success ("positive deviants") may improve the efficacy of web-based weight control interventions. ⋯ User-generated weight-loss practices from "positive deviants" could promote weight control in web-based interventions; however, further research is needed to improve program efficacy.
