Internet-delivered cognitive behaviour therapy (ICBT) is effective for treating anxiety and depression. The relative benefits of offering standard weekly compared to optional weekly therapist support in conjunction with ICBT within routine care has not been examined. Patients seeking ICBT for depression and or anxiety in routine care were randomized to standard (n=92) or optional (n=88) weekly support. The optional approach resulted in therapists receiving half as many messages from (1.70 vs. 3.96) and sending half as many messages to patients (3.62 vs. 7.29). Optional Support was associated with lower completion rates (56.6% versus 82.4%), but, similar to Standard Support, resulted in large reductions on the GAD-7 (within Cohen's d≥1.08; avg. reduction ≥47%) and PHQ-9 (within Cohen's d≥0.82; avg. reduction ≥43%) at post-treatment and 3-month follow-up. Optional weekly support appears clinically effective and acceptable for many patients and may reduce costs, but safety requires monitoring given lower completion rates.
互联网为基础的认知行为疗法（ICBT）在治疗焦虑和抑郁方面是有效的。在常规护理中，与 ICBT 一起提供标准每周与可选每周治疗师支持的相对益处尚未得到检验。在常规护理中寻求 ICBT 治疗抑郁和/或焦虑的患者被随机分配到标准（n=92）或可选（n=88）每周支持。可选方法导致治疗师收到的消息数量减少一半（1.70 对 3.96），发送给患者的消息数量也减少一半（3.62 对 7.29）。可选支持与较低的完成率相关（56.6% 对 82.4%），但与标准支持一样，在治疗后和 3 个月随访时，GAD-7（Cohen's d≥1.08；平均减少≥47%）和 PHQ-9（Cohen's d≥0.82；平均减少≥43%）也有很大的降低。对于许多患者来说，可选的每周支持似乎具有临床效果和可接受性，并且可能降低成本，但由于完成率较低，需要监测安全性。
