The cognitive-behavioral model of hypochondriasis: misinformation and triggers

According to the cognitive-behavioral model, hypochondriacal individuals hold dysfunctional assumptions about illness, which may be triggered by critical incidents. In this study 1,158 participants completed measures of hypochondriacal concerns and self-esteem, and estimated the likelihood of various symptoms indicating catastrophic and minor illnesses. Participants who were more hypochondriacal believed that catastrophic outcomes were more likely than did the less hypochondriacal participants, but they did not differ in their estimates for minor illnesses. Estimates of the likelihood of catastrophic illness and self-esteem independently contributed to the prediction of hypochondriacal concerns. In this study 2,177 participants completed a measure of hypochondriacal concerns, performed a scrambled-sentences task that included either illness terms or neutral terms, and completed a state anxiety inventory. The illness terms did not trigger higher levels of anxiety in the more hypochondriacal participants; instead, these terms appeared to make the less hypochondriacal participants as anxious as their hypochondriacal counterparts.
