Computerized and, more recently, Internet-based treatments for depression have been developed and tested in controlled trials. The aim of this meta-analysis was to summarize the effects of these treatments and investigate characteristics of studies that may be related to the effects. In particular, the authors were interested in the role of personal support when completing a computerized treatment. Following a literature search and coding, the authors included 12 studies, with a total of 2446 participants. Ten of the 12 studies were delivered via the Internet. The mean effect size of the 15 comparisons between Internet-based and other computerized psychological treatments vs. control groups at posttest was d = 0.41 (95% confidence interval [CI]: 0.29-0.54). However, this estimate was moderated by a significant difference between supported (d = 0.61; 95% CI: 0.45-0.77) and unsupported (d = 0.25; 95% CI: 0.14-0.35) treatments. The authors conclude that although more studies are needed, Internet and other computerized treatments hold promise as potentially evidence-based treatments of depression.
计算机化治疗和最近基于互联网的抑郁症治疗已经在对照试验中得到开发和测试。本荟萃分析的目的是总结这些治疗方法的效果，并研究可能与效果相关的研究特征。特别是，作者对在完成计算机化治疗时个人支持的作用很感兴趣。在进行文献检索和编码后，作者纳入了 12 项研究，共有 2446 名参与者。12 项研究中有 10 项是通过互联网进行的。在互联网上进行的与其他计算机化心理治疗相比的 15 项比较的结果，在测试后发现，d = 0.41（95%置信区间[CI]：0.29-0.54）。然而，这种估计受到支持（d = 0.61；95%CI：0.45-0.77）和不支持（d = 0.25；95%CI：0.14-0.35）治疗之间显著差异的调节。作者得出结论，尽管需要更多的研究，但互联网和其他计算机化治疗作为抑郁症的潜在循证治疗方法具有一定的前景。
