Factors associated with inconsistent sun protection in first-degree relatives of melanoma survivors.

First-degree relatives (FDRs) of melanoma survivors are at heightened risk for developing melanoma, but use sun protection inconsistently. To develop appropriate interventions, in this article we identify factors related to sun protection inconsistency in melanoma FDRs using ethnographic decision tree modeling. We conducted in-home interviews with 25 melanoma FDRs balanced across gender and sunbathing attitudes and identified factors related to daily decision making about use of sunscreen, shade seeking, hats, and clothing.
