[1-4] The main goal of our study was to make travel JQ1 supplier health experts aware of differences in risk perception and to encourage more research. We agree that PRISM, an easily applicable tool, needs to be further validated for risk perception research.[3] A number of methods are available, including risk scales and a variety of

questionnaires addressing different aspects of risk perception. As risk perception strongly influences behavior[5] which finally determines the risks, the ideal method to measure people’s risk perception, and eventually to validate other methods, should be consistent with their (changed) behavior. As our priority was to discuss our findings in the context of travel medicine research, integrating concepts of risk perception research would have gone beyond the scope of our study. However, psychological mechanisms influencing risk perception, including both cognitive factors such as the perceived likelihood, severity and susceptibility[5] or the availability heuristic,[6] and emotional factors such as the affect heuristic,[6, 7] are doubtlessly most important to understand risk perception and develop risk conversation strategies.[1] For instance,

optimism or optimism bias, an underestimation of likelihood[8] mentioned by our colleague, most likely influenced the travelers’ risk perception of STIs and other risks. Upon cursory comparison, some of our results differ from findings of risk perception research, for Target Selective Inhibitor Library purchase Docetaxel order example factor-analytic representations, a method of the psychometric paradigm used by our colleague to adjust Figure 3. Factor-analytic representations are three-dimensional frameworks for hazard characteristics. Two axes, the “dread” axis and the “unknown” axis, each represent a set of correlating characteristics while a third axis reflects the number of exposed people. Dread was correlated highest with risk perception.[9] Road traffic accidents, for instance, were

characterized as well-known and medium-dreaded[7, 9] or underestimated in terms of personal mortality[10] whereas accidents were perceived as relatively high risk in our study. However, the perception of risks is not static and depends, among other factors, on study population demographics, voluntariness of exposure,[9] media coverage,[6, 7, 11] and on the context. Many studies explore risk perception of specific health hazards in general[6, 7, 9] or in familiar surroundings.[10, 12] Leisure travel is usually voluntary, time-limited, and often involves visiting unfamiliar places. In the context of travel, dreaded or familiar risks might not be the ones our colleague claims them to be.
