The purpose of the present study was to examine the effectiveness of an Internet-based clinician-assisted computerized cognitive behavioural therapy programme for social phobia.
A total of 105 individuals with social phobia were randomly assigned to a six-lesson cognitive behavioural treatment programme or to a waitlist control group. Treatment consisted of four components: six online lessons; homework assignments; participation in an online discussion forum; and regular email contact with a therapist. An intention-to-treat model was used for data analyses.
A total of 78% of treatment group participants completed all lessons, and post-treatment data were obtained from 93/105 participants. Significant post-treatment differences between treatment and waitlist participants were found on two measures of symptoms of social phobia. Mean within- and between-group effect sizes (Cohen's d) for the primary social phobia outcome measures were 1.15, and 0.95, respectively.
These results were comparable with those obtained in exemplary face-to-face treatment programmes. They provide further positive data about the utility of Internet-based guided self-help programmes for people with common mental disorders.
本研究旨在检验基于互联网的、由临床医生辅助的计算机化认知行为疗法对社交恐惧症的疗效。
总共105名社交恐惧症患者被随机分配到一个六节课的认知行为治疗项目组或候补对照组。治疗包括四个部分：六节在线课程；家庭作业；参与在线讨论论坛；以及与治疗师定期进行电子邮件联系。数据分析采用意向性分析模型。
治疗组中共有78%的参与者完成了所有课程，93/105名参与者提供了治疗后的相关数据。在社交恐惧症症状的两项测量指标上，治疗组和候补组参与者在治疗后存在显著差异。社交恐惧症主要结果测量指标的组内和组间平均效应量（科恩d值）分别为1.15和0.95。
这些结果与在典型的面对面治疗项目中获得的结果相当。它们为基于互联网的引导式自助项目对常见精神障碍患者的效用提供了更多积极数据。
