RESUMEN
OBJECTIVES: Cyberchondria involves the excessive and compulsive use of the Internet to search for health information. The present study investigated the relative contribution of health cognitions and metacognitions about health anxiety to prospective cyberchondria scores, controlling for health anxiety and hours spent online per day. METHODS: A convenience sample of 221 participants was recruited for the purpose of this study with a final sample totaling 125 participants (58.4% females, Mage = 34.51 years) who completed the full survey at baseline (T0 ) and a measure of cyberchondria after 30 days (T1 ). RESULTS: The results of the study showed that metacognition about health anxiety relating to beliefs about the uncontrollability of thoughts was the only significant predictor of prospective cyberchondria scores when controlling for health anxiety. CONCLUSIONS: These results offer further support to the role of beliefs about the uncontrollability of thoughts in cyberchondria. The implications of the findings are discussed.
