BACKGROUND
Exposure-based cognitive-behavioural therapy (CBT) delivered via the internet has been shown to be effective for severe health anxiety (hypochondriasis) but has not been compared with an active, effective and credible psychological treatment, such as behavioural stress management (BSM).
AIMS
To investigate two internet-delivered treatments - exposure-based CBT v. BSM - for severe health anxiety in a randomised controlled trial (trial registration: NCT01673035).
METHOD
Participants (n = 158) with a principal diagnosis of severe health anxiety were allocated to 12 weeks of exposure-based CBT (n = 79) or BSM (n = 79) delivered via the internet. The Health Anxiety Inventory (HAI) was the primary outcome.
RESULTS
Internet-delivered exposure-based CBT led to a significantly greater improvement on the HAI compared with BSM. However, both treatment groups made large improvements on the HAI (pre-to-post-treatment Cohen's d: exposure-based CBT, 1.78; BSM, 1.22).
CONCLUSIONS
Exposure-based CBT delivered via the internet is an efficacious treatment for severe health anxiety.
背景
基于暴露的认知行为疗法（CBT）通过互联网进行已被证明对严重的健康焦虑（疑病症）有效，但尚未与行为压力管理（BSM）等积极、有效和可信的心理治疗进行比较。
目的
在一项随机对照试验（试验注册：NCT01673035）中，研究两种通过互联网提供的治疗方法——基于暴露的 CBT 与 BSM 对严重健康焦虑的疗效。
方法
将主要诊断为严重健康焦虑的参与者（n=158）分配到为期 12 周的基于暴露的 CBT（n=79）或 BSM（n=79）治疗中，通过互联网进行。健康焦虑量表（HAI）是主要结局指标。
结果
与 BSM 相比，基于互联网的暴露 CBT 显著改善了 HAI。然而，两组在 HAI 上都有较大的改善（治疗前至治疗后的 Cohen's d：暴露 CBT，1.78；BSM，1.22）。
结论
通过互联网进行的基于暴露的 CBT 是治疗严重健康焦虑的有效方法。
