Relationships between cyberchondria and obsessive-compulsive symptom dimensions.

Researchers have recently begun to investigate a vicious cycle of escalating physical health concerns and online medical information seeking coined "cyberchondria". Research has shown that cyberchondria is strongly associated with health anxiety (HA), but there is a dearth of work investigating the potential relationships between cyberchondria and other anxiety-related pathologies. One such condition is obsessive-compulsive disorder (OCD), which could theoretically be related to cyberchondria given the physical health relevant focus of certain types of OC symptoms. The current study sought to investigate the potential relationship between cyberchondria OCD across OC symptom dimensions. Community participants (N=468) were recruited via online crowdsourcing to complete a battery of self-report questionnaires including cyberchondria and OC measures. Structural equation modeling revealed significant unique associations between both contamination/washing and responsibility for harm/checking symptoms, and cyberchondria, such that greater cyberchondria was associated with greater OC symptoms after controlling for HA and trait negative affect. These results suggest that similar to proposed models of cyberchondria and HA, cyberchondria could potentially play a role in the development/maintenance of two dimensions of OC symptoms, or vice versa. Future work will need to determine the causal nature of these relationships or whether they are simply co-occurring phenomena.
