Priority of Risk (But Not Perceived Magnitude of Risk) Predicts Improved Sun-Protection Behavior Following Genetic Counseling for Familial Melanoma.

摘要: BACKGROUND Understanding multiple components of risk perceptions is important because perceived predicts engagement in prevention behaviors. PURPOSE To examine how (perceived magnitude and worry about risk, prioritization the management one's risk) changed following genetic counseling with or without test reporting, to which these prospectively predicted improvements sun-protection behavior 1 year later. METHODS A prospective, nonrandomized study design was used. Participants were 114 unaffected members melanoma-prone families who (i) underwent testing for a CDKN2A/p16 mutation (n = 69) (ii) at comparably elevated based on family history but not (no-test controls, n 45). reported perception baseline, immediately counseling, month after counseling. RESULTS Factor analysis indicated three components. Carriers increased priority cancer worry. No-test controls showed no changes any perception. Among noncarriers, remained high all assessments, whereas decreased. Of components, greater uniquely improved self-reported sun protection post-counseling. CONCLUSIONS Priority seems be component distinguishable from worry, may an predictor daily behavior, (iii) only participants received positive melanoma result.
