Measuring Real Time Decision-Making About Ultraviolet Radiation (UVR) Protection

January 5, 2026 updated by: Memorial Sloan Kettering Cancer Center

Measuring Real Time Decision-Making About UVR Protection

The purpose of this study is to understand how people make decisions about sun protection. This study is important in helping to protect against sun exposure, since it is a main risk factor for melanoma. The investigators would like to understand the decisions people make about sun protection so that they can improve their ability to help individuals who may be at risk for melanoma.

Study Overview

Status

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Patients whose FDRs may be eligible for this study will be identified by a member of the patient's treatment team, the protocol investigator, or research team at Memorial Sloan-Kettering Cancer Center (MSKCC) will identify patients who are melanoma patients.

Description

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.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
screening questionnaire
This study will involve two phases. Guided by EDTM, we will first build models of decision-making about UVR protection (sunscreen use, shade-seeking, hat use, use of protective clothing)using in-home ethnographic interviews with 25 melanoma FDRs (Phase I). In Phase II, we will test the validity of each composite model. This will be completed using EMA data collection with 60 different melanoma FDRs from Phase I who will report on their sunscreen use, shade-seeking, use of hat, and use of UVR protective clothing and decision-making regarding these outcomes via interactive voice response (IVR) system and audio narrative diaries (using a digital voice recorder). We will examine the validity of each model and examine the influence of theory-driven affective and cognitive predictors of UVR protection maintenance across time.
Behavioral: screening questionnaire
Phase I involves in-home interviews of 25 participants to understand the factors that affect participants' decision-making about UVR protection (sunscreen use, shade-seeking, hat use, use of protective clothing). In Phase II, we plan to recruit a sample of 60 melanoma first degree relatives (FDRs) and use an electronic narrative diary to record their daily behaviors about UVR protection. They will be asked to carry a interactive voice response (IVR) system for 14 days and they should be in the continental United States.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants Interviewed on UVR Protection Behaviors.
Time Frame: 1 year
To generate models explaining decision-making about four UVR protection behaviors (sunscreen use, shade-seeking, hat use, use of protective clothing) in melanoma FDRs. This was an inductive, qualitative study using an open-ended interview to accomplish the Aim. Cohort 1 was used for this Aim.
1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
To Examine Theory-driven Affective and Cognitive Predictors of UVR Protection Maintenance (Sunscreen Use, Shade-seeking, Hat Use, and Use of UVR Protective Clothing)Assessed in Real Time.
Time Frame: 1 year
To examine theory-driven affective and cognitive predictors of UVR protection maintenance (sunscreen use, shade-seeking, hat use, and use of UVR protective clothing) assessed in real time. Phase 1 was not assessed for this Outcome Measure.
