The authors compared guided Internet-delivered self-help with one session of live-exposure treatment in a sample of spider-phobic patients. A total of 30 patients were included following screening on the Internet and a structured clinical interview. The Internet treatment consisted of five weekly text modules, which were presented on a web page, a video in which exposure was modelled, and support provided via Internet. The live-exposure treatment was delivered in a 3-hr session following a brief orientation session. The main outcome measure was the behavioural approach test (BAT), and as secondary measures the authors used questionnaires measuring anxiety symptoms and depression. Results showed that the groups did not differ at posttreatment or follow-up, with the exception of the proportion showing clinically significant change on the BAT. At posttreatment 46.2% of the Internet group and 85.7% in the live-exposure group achieved this change. At follow-up the corresponding figures were 66.7% for the Internet group and 72.7% for the live treatment. Within-group effect sizes for the spider phobia questionnaire were large (d = 1.84 and 2.58 for the Internet and live-exposure groups, respectively, at posttreatment). The authors conclude that guided Internet-delivered exposure treatment is a promising new approach in the treatment of spider phobia.
作者比较了指导型互联网自助治疗和单次现场暴露治疗在一组蜘蛛恐惧症患者中的效果。共有 30 名患者在互联网筛查和结构化临床访谈后入选。互联网治疗包括五个每周的文本模块，这些模块在网页上呈现，其中包括一个暴露模型的视频，并通过互联网提供支持。现场暴露治疗在简短的介绍会议后进行 3 小时的会议。主要的结果衡量标准是行为接近测试（BAT），作为次要衡量标准，作者还使用了测量焦虑症状和抑郁的问卷。结果显示，两组在治疗后或随访时没有差异，除了 BAT 上显示临床显著变化的比例。在治疗后，互联网组的 46.2%和现场暴露组的 85.7%达到了这一变化。在随访时，互联网组的这一比例为 66.7%，现场治疗组为 72.7%。蜘蛛恐惧症问卷的组内效应大小很大（互联网组和现场暴露组分别为 1.84 和 2.58，治疗后）。作者得出结论，指导型互联网暴露治疗是蜘蛛恐惧症治疗的一种有前途的新方法。
