减少欺凌是公共卫生的优先事项。Kiva,一个以学校为基础的反欺凌计划,有效减少芬兰的欺凌行为,需要在其他国家进行严格的测试,包括英国。该试验旨在测试Kiva在减少英国学校中儿童报告的欺凌行为方面的有效性和成本效益。审判目前正在进行中。招聘于2019年10月开始,但由于COVID-19大流行和由此导致的学校关闭,于2020年10月重新开始。
设计:双臂实用多中心集群随机对照试验,具有嵌入式过程和成本效益评估。
来自四个地区的116所小学;北威尔士,西米德兰兹郡,英格兰东南部和西南部。结果将在学生级别(7-11岁;n=大约13,000名学生)进行评估。
Kiva是一个具有普遍行动的整个学校计划,该计划着重强调改变旁观者的行为,以及为处理欺凌事件提供一致策略的指示行动。Kiva将在一个学年内实施。
通常的做法。
在基线和12个月的随访中,使用广泛使用和验证的OlweusBully/Victim问卷通过自我报告评估学生级别的欺凌受害情况。
学生水平的欺凌行为;学生心理健康和情感幸福感;学生水平,和角色,欺凌;与学校相关的福祉;学校出勤率和学业成绩;以及教师应对欺凌的自我效能感,心理健康,和倦怠。
假定ICC为0.02的116所学校(每个手臂58所)将提供90%的能力,以识别22%的相对减少,具有5%的显着性水平。
招募的学校将按关键阶段2的规模和免费学校膳食状态按1:1分层进行随机分组。过程评估:评估实施保真度,确定对Kiva实施的影响,并检查干预机制。经济评估:自我报告的受害情况,儿童健康实用程序9D,客户服务收据库存,使用服务的频率,干预成本。卫生经济分析将从学校和社会的角度进行。
这项双臂实用多中心集群随机对照试验将评估Kiva抗欺凌干预措施,以产生有效性的证据。该计划在英国的成本效益和可扩展性。我们的综合流程评估将评估实施保真度,确定对英格兰和威尔士实施Kiva的影响,并检查干预机制。综合卫生经济分析将从学校和社会的角度进行。我们的试验还将通过测试Kiva在整个社会经济梯度中是否有效,提供有关计划对不平等影响的证据。

Reducing bullying is a public health priority.
KiVa, a school-based anti-bullying programme, is effective in reducing bullying in Finland and requires rigorous testing in other countries, including the UK. This trial aims to test the effectiveness and cost-effectiveness of
KiVa in reducing child reported bullying in UK schools compared to usual practice. The trial is currently on-going. Recruitment commenced in October 2019, however due to COVID-19 pandemic and resulting school closures was re-started in October 2020.
Design: Two-arm pragmatic multicentre cluster randomised controlled trial with an embedded process and cost-effectiveness evaluation.
116 primary schools from four areas; North Wales, West Midlands, South East and South West England. Outcomes will be assessed at student level (ages 7-11 years; n = approximately 13,000 students).
KiVa is a whole school programme with universal actions that places a strong emphasis on changing bystander behaviour alongside indicated actions that provide consistent strategies for dealing with incidents of bullying.
KiVa will be implemented over one academic year.
Usual practice.
Student-level bullying-victimisation assessed through self-report using the extensively used and validated Olweus Bully/Victim questionnaire at baseline and 12-month follow-up.
student-level bullying-perpetration; student mental health and emotional well-being; student level of, and roles in, bullying; school related well-being; school attendance and academic attainment; and teachers\' self-efficacy in dealing with bullying, mental well-being, and burnout.
116 schools (58 per arm) with an assumed ICC of 0.02 will provide 90% power to identify a relative reduction of 22% with a 5% significance level.
recruited schools will be randomised on 1:1 basis stratified by Key-Stage 2 size and free school meal status. Process evaluation: assess implementation fidelity, identify influences on KiVa implementation, and examine intervention mechanisms. Economic evaluation: Self-reported victimisation, Child Health Utility 9D, Client Service Receipt Inventory, frequency of services used, and intervention costs. The health economic analysis will be conducted from a schools and societal perspective.
This two-arm pragmatic multicentre cluster randomised controlled trial will evaluate the KiVa anti-bullying intervention to generate evidence of the effectiveness, cost-effectiveness and scalability of the programme in the UK. Our integrated process evaluation will assess implementation fidelity, identify influences on KiVa implementation across England and Wales and examine intervention mechanisms. The integrated health economic analysis will be conducted from a schools and societal perspective. Our trial will also provide evidence regarding the programme impact on inequalities by testing whether
KiVa is effective across the socio-economic gradient.
