Cyberchondria and intolerance of uncertainty: examining when individuals experience health anxiety in response to Internet searches for medical information.

Individuals frequently use the Internet to search for medical information. However, for some individuals, searching for medical information on the Internet is associated with an exacerbation of health anxiety. Researchers have termed this phenomenon as cyberchondria. The present research sought to shed further light onto the phenomenology of cyberchondria. In particular, the moderating effect of intolerance of uncertainty (IU) on the relationship between the frequency of Internet searches for medical information and health anxiety was examined using a large sample of medically healthy community adults located in the United States (N=512). The purported moderating effect of IU was supported. More specifically, the relationship between the frequency of Internet searches for medical information and health anxiety grew increasingly stronger as IU increased. This moderating effect of IU was not attributable to general distress. These results suggest that IU is important for better understanding the exacerbation of health anxiety in response to Internet searches for medical information. Conceptual and therapeutic implications of these results are discussed.
