AbstractInternet addiction and cyberchondria have a bidirectional relationship. However, no known studies have evalu￾ated the moderating role of anxiety sensitivity in that relationship. The study aimed to determine whether anxi￾ety sensitivity moderates the relationship between internet addiction and cyberchondria among Jordaniannurses. Data were collected from 303 nurses using a web-based survey and convenience snowballing samplingmethods using a cross-sectional research design. The Internet Addiction Test and the short version of theCyberchondria Severity Scale were used to assess internet addiction and cyberchondria. Nurses reported mildinternet addiction, low anxiety sensitivity, and moderate cyberchondria. Also, these findings suggested that sensi￾tivity to anxious feelings moderates the relationship between internet addiction and cyberchondria. These find￾ings would help nurses use psychosocial interventions for people with internet addiction and cyberchondria byunderstanding how their anxiety sensitivity promotes their internet addiction and cyberchondria.Keywordscyberchondria, health anxiety, health sensitivity, internet addiction, nurse
