Comparison of interventions to reduce sun exposure.

Exposure to ultraviolet (UV) light is the leading behavioral cause of skin cancer. This study evaluated the efficacy of 2 interventions to reduce UV exposure in college students prior to an opportunity for high-intensity expo- sure. Participants of 1 college campus were assigned randomly to 1 of 2 interventions prior to their spring holiday spent in a warm, sunny location: (1) a community-based informational campaign, or (2) a combination of the campaign and a cognitive-behavioral small group intervention. Participants of a second college campus served as a comparison group. The cognitive-behavioral group exhibited increased knowledge, more positive attitudes toward UV protection, greater advancement through stages of change, and greater protective clothing use relative to the comparison or community-education groups. The informational campaign had little apparent impact in this study.
