Online treatments for child anxiety offer a potentially cost-effective and non-stigmatizing means to widen access to evidence-based treatments and meet the increasing demand on services; however, uptake in routine clinical practice remains a challenge. This study conducted an initial evaluation of the clinical effectiveness, feasibility and acceptability of OSI (Online Support and Intervention for child anxiety) within clinical practice. OSI is a co-designed online therapist-supported, parent-led CBT treatment for pre-adolescent children with anxiety problems.

This case series was part of routine service evaluation in a clinic in England where families were offered OSI to treat a primary anxiety difficulty among 7- to 12-year-old children; 24 families were offered OSI, and 23 took it up. Measures of anxiety symptomatology, functional impairment and progress towards therapeutic goals were taken at pre-treatment, post-treatment and 4-week follow-up. Treatment satisfaction and engagement were also measured throughout the intervention.

Mean anxiety symptoms significantly improved to below the clinical cut-off post-treatment, with further reduction at follow-up. Functional impairment also significantly improved and significant progress was made towards treatment goals. The majority of children showed reliable change in anxiety symptoms and reliable recovery by follow-up, and were discharged without needing further treatment for anxiety. Uptake, adherence and engagement in OSI were excellent, and parents reported high levels of satisfaction with the treatment.

We have provided initial evidence that OSI is feasible, acceptable to families, and appears to be associated with good outcomes within routine clinical practice.

儿童焦虑症的在线治疗提供了一种潜在的具有成本效益和非污名化的手段，以扩大获得循证治疗的机会并满足对服务日益增长的需求；然而，在常规临床实践中的应用仍然是一个挑战。本研究对 OSI（儿童焦虑在线支持和干预）在临床实践中的临床有效性、可行性和可接受性进行了初步评估。OSI 是一个共同设计的在线治疗师支持、家长主导的 CBT 治疗，用于治疗有焦虑问题的青春期前儿童。

该病例系列是英格兰一家诊所常规服务评估的一部分，该诊所为家庭提供 OSI 以治疗 7 至 12 岁儿童的原发性焦虑困难；为 24 个家庭提供了 OSI，其中 23 个接受了它。在治疗前、治疗后和 4 周的随访中对焦虑症状、功能障碍和治疗目标的进展进行了测量。在整个干预过程中还测量了治疗满意度和参与度。

平均焦虑症状在治疗后显着改善至临床临界值以下，随访时进一步减少。功能障碍也显着改善，治疗目标也取得了显着进展。大多数儿童在随访中表现出焦虑症状的可靠变化和可靠的恢复，并且无需进一步治疗焦虑即可出院。对 OSI 的吸收、依从性和参与度非常好，父母对治疗表示高度满意。

我们提供的初步证据表明 OSI 是可行的、家庭可以接受的，并且似乎与常规临床实践中的良好结果相关。
