BACKGROUND
Internet-based cognitive behavioural therapy (iCBT) for depression is effective when guided by a clinician, less so if unguided.
QUESTION
Would guidance from a technician be as effective as guidance from a clinician?
METHOD
Randomized controlled non-inferiority trial comparing three groups: Clinician-assisted vs. technician-assisted vs. delayed treatment. Community-based volunteers applied to the VirtualClinic (www.virtualclinic.org.au) research program, and 141 participants with major depressive disorder were randomized. Participants in the clinician- and technician-assisted groups received access to an iCBT program for depression comprising 6 online lessons, weekly homework assignments, and weekly supportive contact over a treatment period of 8 weeks. Participants in the clinician-assisted group also received access to a moderated online discussion forum. The main outcome measures were the Beck Depression Inventory (BDI-II) and the Patient Health QUESTIONnaire-9 Item (PHQ-9). Completion rates were high, and at post-treatment, both treatment groups reduced scores on the BDI-II (p<0.001) and PHQ-9 (p<0.001) compared to the delayed treatment group but did not differ from each other. Within group effect sizes on the BDI-II were 1.27 and 1.20 for the clinician- and technician-assisted groups respectively, and on the PHQ-9, were 1.54 and 1.60 respectively. At 4-month follow-up participants in the technician group had made further improvements and had significantly lower scores on the PHQ-9 than those in the clinician group. A total of approximately 60 minutes of clinician or technician time was required per participant during the 8-week treatment program.
CONCLUSIONS
Both clinician- and technician-assisted treatment resulted in large effect sizes and clinically significant improvements comparable to those associated with face-to-face treatment, while a delayed treatment control group did not improve. These results provide support for large scale trials to determine the clinical effectiveness and acceptability of technician-assisted iCBT programs for depression. This form of treatment has potential to increase the capacity of existing mental health services.

背景
基于互联网的认知行为疗法(iCBT)在有临床医生指导时有效,如果没有指导则效果较差。
问题
技术人员的指导是否与临床医生的指导一样有效?
方法
比较三组的随机对照非劣效性试验:临床医生辅助组、技术人员辅助组和延迟治疗组。社区志愿者申请参加 VirtualClinic(www.virtualclinic.org.au)研究计划,141 名患有重度抑郁症的参与者被随机分组。在临床医生和技术人员辅助组中,参与者可以使用包含 6 个在线课程、每周家庭作业和 8 周治疗期间每周支持性联系的抑郁 iCBT 计划。临床医生辅助组的参与者还可以访问一个经过Moderated(审核)的在线讨论论坛。主要结局指标是贝克抑郁量表(BDI-II)和患者健康问卷-9 项(PHQ-9)。完成率很高,在治疗后,两组的 BDI-II(p<0.001)和 PHQ-9(p<0.001)评分均低于延迟治疗组,但彼此之间没有差异。在 BDI-II 上的组内效应大小分别为临床医生辅助组的 1.27 和技术人员辅助组的 1.20,在 PHQ-9 上,分别为 1.54 和 1.60。在 4 个月的随访中,技术人员组的参与者进一步改善,PHQ-9 得分显著低于临床医生组。在 8 周的治疗计划中,每个参与者大约需要 60 分钟的临床医生或技术人员时间。
结论
临床医生和技术人员辅助治疗均导致大的效应量和临床显著改善,与面对面治疗相关的改善相当,而延迟治疗对照组则没有改善。这些结果为确定技术人员辅助 iCBT 方案治疗抑郁症的临床有效性和可接受性的大规模试验提供了支持。这种治疗形式有可能增加现有心理健康服务的能力。
