Up until now, only two studies have explicitly focused on the role of emotion regulation strategies in hypochondriasis and health anxiety [14, 15]. Fergus and Valentiner [14] found inasampleofstudents(N=503;Mage=19.1,SDage=2.3years; 68 % female) that the regulation strategies cognitive avoidance (β=.09) and reappraisal (β=−.11) are significant predictors of disease convictions. Marcus et al. [15] investigated the relationship between health anxiety and the regulation strategies of rumination and catastrophizing. In this study (N= 198 students; Mage=21.1, SDage=4.1 years; 76 % female), a significant correlation (r=.24) between rumination and health anxietywasfound.Thisassociationdidnotonlyresultfromthe shared variance with negative affectivity because rumination was also directly related to health anxiety. The results also showed that catastrophizing ambiguous bodily symptoms (e.g.,tointerpretheadacheasasignofabraintumor)isdirectly associated with health anxiety (r=.19).
