基于互联网的干预措施可以有效治疗焦虑和抑郁。元分析证据表明，它们应该在人的支持下提供，以达到最佳效果。然而，这些发现并没有在支持和不支持的干预措施的直接比较中得到一致的复制。本研究探讨了支持在基于互联网的问题解决治疗（PST）的焦虑和/或抑郁症状的作用。从一般人群中招募具有轻度至中度焦虑和/或抑郁症状的成人，并随机分配至：（I）无支持的PST（n = 107），（2）按要求提供支持的PST（n = 108），（3）每周提供支持的PST（n = 106），（4）无基于互联网的干预，但非特定聊天或电子邮件（n = 110），（5）等待列表控制（WLC; n = 106）。主要结果是基线和6周后测量的焦虑症状（HADS）和抑郁症状（CES-D）。首先根据意向治疗原则（ITT）进行分析，并对干预完成者进行重复分析。只有接受每周支持的PST的参与者在抑郁症状方面的改善程度显着高于WLC。焦虑的结果不太稳健，但有利于每周的支持条件。研究结果强调了结构性支持在基于互联网的抑郁和焦虑干预中的重要性。爱思唯尔有限公司出版
Internet-based interventions can be effective treatments for anxiety and depression. Meta-analytic evidence suggests that they should be delivered with human support to reach optimal effects. These findings have not consistently been replicated in direct comparisons of supported and unsupported interventions, however. This study examined the role of support in Internet-based problem solving treatment (PST) for symptoms of anxiety and/or depression. Adults with mild to moderate symptoms of anxiety and/or depression were recruited from the general population and randomized to: (I) PST without support (n = 107), (2) PST with support on request (n = 108), (3) PST with weekly support (n = 106), (4) no Internet-based intervention but non-specific chat or email (n = 110), or (5) waitlist control (WLC; n = 106). Primary outcomes were symptoms of anxiety (HADS) and depression (CES-D) measured at baseline and 6 weeks later. Analyses were first based on the intention-to-treat principle (ITT) and repeated with intervention completers. Only participants who received PST with weekly support improved significantly more than WLC for depressive symptoms. Results for anxiety were less robust but in favor of the weekly support condition. The results underscore the importance of structural support in Internet-based interventions for depression and anxiety. Published by Elsevier Ltd.
