Randomized controlled trial of a sun protection intervention for children of melanoma survivors

We studied whether a melanoma survivor-centered intervention was more effective than materials available to the general public in increasing children's sun protection.

In a randomized controlled trial, melanoma survivors (n = 340) who had a child ≤ 12 years received a targeted sun protection intervention (DVD and booklets) or standard education. Primary outcomes were children's sunburns, children's sun protection, and survivors' psychosocial factors at baseline and postintervention (1 and 4 months).

The intervention increased children's sunscreen reapplication at 1 month (P = 0.002) and use of wide-brimmed hats at 4 months (P = 0.045). There were no effects on other behaviors or sunburns. The intervention improved survivors' hats/clothing self-efficacy at both follow-up assessments (P = 0.026, 0.009). At 4 months, the intervention improved survivors' clothing intentions (P = 0.029), knowledge (P = 0.010), and outcome expectations for hats (P = 0.002) and clothing (P = 0.037). Children's sun protection increased with survivors' intervention use. The intervention was less effective in survivors who were female or who had a family history, older children, or children with higher baseline sun protection scores.

A melanoma survivor-centered sun protection intervention can improve some child and survivor outcomes. The intervention may be more effective in survivors who have younger children or less experience with sun protection. Intervention delivery must be enhanced to maximize use.

This is the first study to examine a sun protection intervention for children of melanoma survivors. Findings will guide interventions for this important population at increased melanoma risk.
