Abstract
Introduction Moving beyond numeric representations of risk perceptions, we examine cognitive causation, or superstitious thinking, and negative affect in risk as predictors of MC1R (i.e., moderate v. high risk) skin cancer genetic testing and responses to this testing. Methods Participants ( N = 496) completed baseline assessments using validated measures of cognitive causation (beliefs that thinking about cancer risk increases cancer likelihood) and negative affect in risk (negative feelings generated during risk perception) and subsequently received a test offer. Participants could access a website to learn about and request genetic testing. Those who tested ( n = 167) completed assessments of cognitive and affective reactions 2 wk after testing, including the Impact of Events–Revised Intrusive thoughts subscale. Results Those with higher negative affect in risk were less likely to return a saliva sample for testing (odds ratio = 0.98, 95% confidence interval = 0.96–0.99). Those with higher cognitive causation reported more fear ( b = 0.28–0.31; P ’s
