In Japan, 'Journey of the Brave', a cognitive behavioural therapy (CBT)-based anxiety preventive education programme, was previously developed and its effectiveness examined in two small-scale controlled trials. These studies had some limitations, including a small number of participants and not having regular classroom teachers as programme facilitators. Therefore, we conducted a large-scale controlled trial, with teachers as programme implementers.
Twenty-seven elementary schools participated: 1622 and 1123 children were allocated to the intervention and control groups, respectively. The intervention group received a programme comprising ten 45-min sessions, while the control group underwent the regular school curriculum. Anxiety symptoms among participants were assessed using the Spence Children's Anxiety Scale (SCAS) at three stages (pre-intervention, post-intervention, and follow-up).
Following primary analysis, estimated mean changes in SCAS from baseline to follow-up were - 4.91 (95% CI - 5.91, - 3.90) in the intervention group and - 2.53 (95% CI - 3.52, - 1.54) in the control group; the group difference was 2.37 (95% CI 1.42, 3.33, p < 0.0001). Children in the intervention group showed significant reduction in their anxiety score versus children in the control group.
The results showed a statistically significant anxiety score reduction in the intervention group, thus verifying the programme's effectiveness.

在日本，先前开发了一项名为“勇敢之旅”的基于认知行为疗法（CBT）的焦虑预防教育计划，并在两项小规模对照试验中检验了其有效性。这些研究存在一些局限性，包括参与者数量少以及没有正规的课堂教师作为计划实施者。因此，我们进行了一项大规模对照试验，由教师作为计划实施者。
27所小学参与其中：分别将1622名和1123名儿童分配到干预组和对照组。干预组接受了一个由十节45分钟课程组成的计划，而对照组则接受常规学校课程。在三个阶段（干预前、干预后和随访）使用斯宾斯儿童焦虑量表（SCAS）评估参与者的焦虑症状。
经过初步分析，干预组从基线到随访时SCAS的估计平均变化为-4.91（95%CI -5.91，-3.90），对照组为-2.53（95%CI -3.52，-1.54）；组间差异为2.37（95%CI 1.42，3.33，p<0.0001）。与对照组儿童相比，干预组儿童的焦虑得分显著降低。
结果显示干预组的焦虑得分在统计学上有显著降低，从而验证了该计划的有效性。试验注册 大学医院医学信息网络（UMIN）：UMIN000032517。2018年5月10日注册——追溯注册，https://upload.umin.ac.jp/cgi-open-bin/ctr_e/ctr_view.cgi?recptno=R000037083。
