We thank Signorelli et. al. for their interest in our article 1 and for sharing the complementary data from their ANZCHOG Survivorship Study, which included 402 long-term childhood cancer survivors from Australia and New Zealand. They found higher proportions of survivors who were not worried about late effects (57%) and subsequent neoplasms (60%) compared to our results for reported levels of concern in the North American Childhood Cancer Survivor Study, but certainly both studies highlight the fact that a substantial subgroup of survivors have low levels of concern about their future health. We would like to reiterate here that the goal of survivorship education and care should be to provide survivors with an understanding of the potential late effects associated with childhood cancer and treatments and to foster an appropriate level of concern, which may not be uniform for all survivors. Therefore, it is important to consider survivors' treatment history and risk profile when evaluating their reported levels of concern. Ultimately, some degree of concern may be beneficial if it motivates at-risk survivors to take an active role in their health care and follow established survivorship care guidelines. Accordingly, we were very interested to see the data from Signorelli et al. from their analyses of associations between perceptions of risk or degree of worry and engagement with follow-up care. However, it is important to note that their analysis was based on cross-sectional data. Because survivors reported their current follow-up engagement at the same time they reported their risk perceptions and levels of worry, it is impossible to determine the direction of their reported associations. Levels of perceived risk and frequency of worries may influence follow-up engagement, but it is also plausible that survivors exposed to more follow-up care have different perceptions and worries as a result. We faced similar issues in our analysis, where we were only able to examine self-reported screening behaviors in a subgroup of survivors with longitudinal data. Additional studies are warranted that can prospectively examine the impact that survivors' levels of concern or worry may have on their future behaviors. We fundamentally agree with Signorelli et. al. in their assertion that the key objective of future efforts should be maximizing survivors' understanding of their personal health risks, promoting risk
