Internet-based cognitive-behavioural therapy for severe health anxiety: randomised controlled trial
Open accessAbstract
Background: Hypochondriasis, characterised by severe health anxiety, is a common condition associated with functional disability. Cognitive–behavioural therapy (CBT) is an effective but not widely disseminated treatment for hypochondriasis. Internet-based CBT, including guidance in the form of minimal therapist contact via email, could be a more accessible treatment, but no study has investigated internet-based CBT for hypochondriasis. Aims: To investigate the efficacy of internet-based CBT for hypochondriasis. Method: A randomised controlled superiority trial with masked assessment comparing internet-based CBT ( n = 40) over 12 weeks with an attention control condition ( n = 41) for people with hypochondriasis. The primary outcome measure was the Health Anxiety Inventory. This trial is registrated with ClinicalTrials.gov (NCT00828152). Results: Participants receiving internet-based CBT made large and superior improvements compared with the control group on measures of health anxiety (between-group Cohen's d range 1.52–1.62). Conclusions: Internet-based CBT is an efficacious treatment for hypochondriasis that has the potential to increase accessibility and availability of CBT for hypochodriasis.

In the citing paper
“In a series of randomised controlled trials (RCTs), Hedman and colleagues have demonstrated the efficacy of internet-delivered CBT (iCBT) for health anxiety, and showed that it outperforms control groups (online forums and internet-delivered behavioural stress management), and leads to improvements in health anxiety that are maintained up to 1-year follow-up ( Hedman et al., 2011 ; Hedman, AxelSSO”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
