  abstract  = {This study examined the effectiveness of psychological interventions for severe health anxiety (SHA) regarding somatic symptoms (SS) and health anxiety (HA). The databases Web of Science, EBSCO, and CENTRAL were searched on May 15, 2019, May 16, 2019, and August 5, 2019, respectively. Eighteen randomized controlled trials (N = 2,050) met the inclusion criteria (i.e., hypochondriasis, illness anxiety disorder or somatic symptom disorder with elevated HA being assessed with validated interviews: use of standardized outcome measures). Two reviewers independently evaluated the studies' risk of bias using the Revised Cochrane Risk-of-Bias Tool for randomized trials (RoB-2) tool. Overall, psychological interventions were significantly more effective than waitlist, treatment-as-usual, or placebo post-treatment (g(SS) = 0.70, g(HA) = 1.11) and at follow-up (g(SS) = 0.33, g(HA)= 0.70). CBT outperformed other psychological interventions or pharmacotherapy for HA post- treatment (Hedge's g(HA) = 0.81). The number of sessions did not significantly predict the effect sizes. In sum, psychological interventions were effective for SHA, but the generalizability of the results for SS is limited, because only two high-quatity trials contributed to the comparison.},

  abstract  = {ObjectivePsychotherapy for hypochondriasis has greatly improved over the last decades and cognitive-behavioral treatments are most promising. However, research on predictors of treatment outcome for hypochondriasis is rare. Possible predictors of treatment outcome in cognitive therapy (CT) and exposure therapy (ET) for hypochondriasis were investigated. MethodCharacteristics and behaviors of 75 patients were considered as possible predictors: sociodemographic variables (sex, age, and cohabitation); psychopathology (pretreatment hypochondriacal symptoms, comorbid mental disorders, and levels of depression, anxiety, and somatic symptoms); and patient in-session interpersonal behavior. ResultsSeverity of pretreatment hypochondriacal symptoms, comorbid mental disorders, and patient in-session interpersonal behavior were significant predictors in multiple hierarchical regression analyses. Interactions between the predictors and the treatment (CT or ET) were not found. ConclusionsIn-session interpersonal behavior is an important predictor of outcome. Furthermore, there are no specific contraindications to treating hypochondriasis with CT or ET.},

  abstract  = {Objective: Cognitive-behavioral therapy (CBT) has been shown to be effective in treating hypochondriasis. However, there are doubts regarding the long-term effectiveness of CBT for hypochondriasis, in particular for follow-up periods longer than 1 year. The aim of the present study was to evaluate the long-term effectiveness of cognitive therapy (CT) and exposure therapy (ET) for the treatment of hypochondriasis. Method: Seventy-five patients with a diagnosis of hypochondriasis who were previously treated with CT or ET were contacted 3 years after treatment. Fifty (67\%) patients participated and were interviewed by an independent and blinded diagnostician using standardized interviews. Results: We found further improvements after therapy in primary outcome measures (d = .37), general functioning (d = .38), and reduced doctor visits (d = .30) during the naturalistic follow-up period. At the 3-year follow-up, 72\% of the patients no longer fulfilled the diagnosis of hypochondriasis. Based on the main outcome measure, we found response rates of 76\% and remission rates of 68\%. At follow-up, only 4\% of patients were taking antidepressant medication. Additional psychological treatment was utilized by 18\% of the patients during the follow-up period (only 8\% because of health anxiety). We found no overall differences between CT and ET. Only a trend for a greater deterioration rate in CT (13\%) in comparison to ET (0\%) was found. Conclusions: Our results suggest that 2/3 of the patients with hypochondriasis were remitted in the long term. Thus, remission rates after CBT were twice as high as in untreated samples.},
