Is cyberchondria specific to hypochondriasis?

Cyberchondria (i.e., excessive health-related Internet search linked to psychological distress) is usually associated with health anxiety, but relationships with other psychopathological symptoms were also found. However, studies are lacking in patients with hypochondriasis, and it remains unclear whether cyberchondria and its subfacets are specific to hypochondriasis (i.e., higher levels in hypochondriasis compared to other mental disorders). Patients with hypochondriasis (N = 50), a clinical (N = 70), and a healthy comparison group (N = 51) completed two questionnaires on cyberchondria whose combined 17 subscales were reduced to three relevant cyberchondria subfacets by second-order factor analysis. The cyberchondria subfacet emotional distress/negative consequences linked to health-related Internet searches showed significantly higher scores in patients with hypochondriasis than in the two comparison groups (d >= 1.7) and was the only predictor of dimensional health anxiety (beta = .58, p <= .001). The two subfacets type/extent of health-related Internet searches and characteristics of the Internet (e.g., attitude toward unreliability, vast amounts of information) were less specifically associated with hypochondriasis. The results are consistent with models of cyberchondria and hypochondriasis, particularly on the anxiety-reinforcing vicious circle and maintaining factors. Based on the findings, practical implications are discussed.
