基于互联网和计算机的认知行为治疗已被引入作为新的方法来提供标准，高质量的治疗，可以减少护理的障碍。本综述的目的是定量总结文献研究的治疗效果，互联网或计算机为基础的治疗（ICT）对焦虑。确定了19项随机对照ICT试验，并采用固定效应和随机效应荟萃分析技术。加权平均效应量（Cohen’s d）显示，ICT在结果测量中上级等待名单和安慰剂分配（ds = 0.49 -1.14）。ICT的效果也等同于治疗师提供的焦虑症治疗。然而，由于样本量小、很少使用安慰剂对照和其他方法学问题，结论受到限制。此外，现有研究的数量限制了按诊断小组进行分析的机会;初步支持使用信通技术治疗惊恐障碍和恐怖症。需要大型的、设计良好的安慰剂对照试验来证实和扩展这项荟萃分析的结果。(C)2008 Wiley Periodicals，Inc.

Internet-and computer-based cognitive-behavioral treatments have been introduced as novel approaches to deliver standard, quality treatment that may reduce barriers to care. The purpose of this review is to quantitatively summarize the literature examining the treatment effects of Internet- or computer-based treatment (ICT) on anxiety. Nineteen randomized controlled ICT trials were identified and subjected to fixed and random effects meta-analytic techniques. Weighted mean effect sizes (Cohen's d) showed that ICT was superior to waitlist and placebo assignment across outcome measures (ds = .49-1.14). The effects of ICT also were equal to therapist-delivered treatment across anxiety disorders. However, conclusions were limited by small sample sizes, the rare use of placebo controls, and other methodological problems. In addition, the number of available studies limited the opportunity to conduct analyses by diagnostic group; there was preliminary support for the use of ICT for panic disorder and phobia. Large, well-designed, placebo-controlled trials are needed to confirm and extend the results of this meta-analysis. (C) 2008 Wiley Periodicals, Inc. J Clin Psychol 65: 53-75, 2009.
