This study examined how message framing effects can be moderated by two types of risk: (a) perceived effectiveness in preventing a risk and (b) perceived susceptibility to the risk. The results indicate that the perceived effectiveness moderated framing effects on the intention to use sunscreen such that a loss-framed message was more effective when perceived effectiveness was low, whereas a gain-framed message was more effective when perceived effectiveness was high. In addition, perceived susceptibility to skin cancer moderated framing effects on the intention to use sunscreen and the intention to wear long pants such that a loss-framed message was more effective when perceived susceptibility was high.
