背景：在随机对照试验中，互联网网站被证明在治疗抑郁和焦虑方面是有效的。目的：比较认知行为治疗网站(http://moodgym.anu.edu.au))自发访问者的焦虑和抑郁结果与同一网站的随机对照疗效试验的结果。方法：对2001年4月至2003年9月期间MoodGYM网站的所有社区访问者进行抽样：作为大型试验的一部分，随机分配到MoodGYM网站的182名参与者和访问该网站的19607名访问者(公共注册者)。症状评估(测验)在网站干预中重复进行，以允许检查跨模块的症状变化。结果：结果变量是(1)年龄、性别、初始抑郁严重程度评分和尝试评估的次数，以及(2)基于Goldberg焦虑和抑郁评分的症状变化测量，至少记录两次。结果：公共登记者和试验参与者在性别、年龄或初始抑郁水平上没有差异，相对于先前发表的流行病学数据集，两组患者的抑郁水平都较高。试验参与者完成了更多的评估。焦虑或抑郁的变化得分没有显著差异，公共注册者和试验参与者都通过培训计划得到了改善。结论：认知行为疗法网站的公共注册者在焦虑和抑郁症状方面发生了显著变化。变化的程度与在网站上登记参加随机对照试验的参与者没有不同。
Background: In randomized controlled trials Internet sites have been shown to be effective in the treatment of depression and anxiety. However, it is unclear if the positive effects demonstrated in these trials transfer to community users of such sites.Objective: To compare anxiety and depression outcomes for spontaneous visitors to a publicly accessible cognitive behavior therapy website (MoodGYM) (http://moodgym.anu.edu.au) with outcomes achieved through a randomized controlled efficacy trial of the same site.Methods: All community visitors to the MoodGYM site between April 2001 and September 2003 were sampled: 182 participants in the BlueMood Trial who had been randomly assigned to the MoodGYM site as part of a large trial and 19607 visitors (public registrants) to the site. Symptom assessments (quizzes) were repeated within the website intervention to allow the examination of change in symptoms across modules. Outcome variables were (1) age, gender, initial depression severity scores, and number of assessments attempted, and (2) symptom change measures based on Goldberg anxiety and depression scores recorded on a least two occasions.Results: Public registrants did not differ from trial participants in gender, age, or initial level of depression, which was high for both groups relative to previously published epidemiological data sets. Trial participants completed more assessments. No significant differences in anxiety or depression change scores were observed, with both public registrants and trial participants improving through the training program.Conclusions: Public registrants to a cognitive behavior therapy website show significant change in anxiety and depression symptoms. The extent of change does not differ from that exhibited by participants enrolled on the website for a randomized controlled trial.
