Perceived susceptibility to breast cancer moderates the effect of gain- and loss-framed messages on use of screening mammography.

Abstract

This study examined the role of three distinct beliefs about risk (risks associated with screening, construal of the function of screening as health-affirming or illness-detecting, and perceived susceptibility to breast cancer) in moderating women's responses to framed messages that promote mammography. Three hundred fifty-five women recruited from an inner city hospital, nonadherent to guidelines for receiving annual screening mammograms,were randomly assigned to view a gain- or loss-framed video message about the importance of mammography. Mammography screening was self-reported at a 3-month follow-up. Only perceived susceptibility to breast cancer significantly moderated the effect of message framing on screening. Women with average and higher levels of perceived susceptibility for breast cancer were significantly more likely to report screening after viewing a loss-framed message compared to a gain-framed message. No effects of framing on reported screening were observed for women with lower levels of perceived susceptibility. The study identifies a key role for perceived susceptibility in shaping responses to framed messages that promote cancer screenings.
