Summary

This completed study from Memorial Sloan Kettering Cancer Center looked at how people with a close family member who had melanoma make decisions about sun protection. Researchers interviewed 94 participants and used an electronic diary to track daily behaviors like sunscreen use and seeking shade. The goal was to understand the factors behind these choices to help improve future sun safety programs.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this research could help design better programs to encourage sun protection in people with a family history of melanoma.
What could go wrong
This is a small, observational study that does not test any treatment. The findings may not apply to everyone and are meant to guide future research, not provide immediate solutions.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * A first-degree biological relative (a child, sibling or parent) as per self report of an MSKCC follow-up surgical patient diagnosed with melanoma as per pathology report or clinician's judgment; * English-fluent; the surveys were designed and validated in English and are not currently available in other languages. Translation of questionnaires into other languages would require reestablishing the reliability and validity of these measures. Therefore, participants must be able to communicate in English to complete the surveys. * 18 years of age or older; * For Phase I only: FDRs who live within a 50 mile radius of MSKCC to make it feasible for Ms. Shuk to be able to arrive at each person's home for the in-home interview without the cost being prohibitive; * For Phase I only: Can recall a period when s/he was out in the sun for at least one hour on a sunny day this past summer 2009. * For Phase I only: Can recall a separate period when s/he was out in the sun for at least one hour on a sunny day this past summer 2009, but s/he was in a different location from the period referenced above. * For Phase II only: FDRs who self-report at least 1 consecutive hour in the morning (dawn to 12:30pm) and 1 consecutive hour in the afternoon (12:30-5pm) of daily (weekend and weekday) outdoor activities on the screening questionnaire Exclusion Criteria: * First-degree relatives of melanoma patients who report never using UVR protection; * Patient's who provide consent for Phase I will not be eligible for Phase II. * Any first-degree relative of a melanoma patient who already has a first-degree relative who consented to the study; * Unable to provide informed consent.
