Measuring Real Time Decision-Making About Ultraviolet Radiation (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 Design:||Observational Model: Cohort
Time Perspective: Prospective
|Official Title:||Measuring Real Time Decision-Making About UVR Protection|
- To generate models explaining decision-making about four UVR protection behaviors (sunscreen use, shade-seeking, hat use, use of protective clothing) in melanoma FDRs. [ Time Frame: 1 year ] [ Designated as safety issue: No ]
- 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 ] [ Designated as safety issue: No ]
|Study Start Date:||October 2009|
|Estimated Study Completion Date:||October 2015|
|Estimated Primary Completion Date:||October 2015 (Final data collection date for primary outcome measure)|
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.
