Overall, crises and disasters have increased in the past decade, crises. Many studies that measure risk perceptions in relation to travel and tourism fail to properly conceptualize risk and ground their measures in theory. In order to advance the risk perception literature, theory must underlie and frame effective studies. Risk perceptions have been extended by adopting health theories and constructs. Outside of tourism, literature has advanced risk perceptions to include both cognitive and affective measures. Travel anxiety represents a measure of affective perceptions based upon the risk-as-feelings hypothesis. Travel anxiety and cognitive risk perceptions sum to provide overall risk perceptions. Recently, risk theorists have suggested an additional dimension – experiential risk perceptions. The chapter will outline the need for ongoing collection of risk perception data and how risk perceptions can be based in theory and conceptualized.
