In this paper, we present the protocol for a cluster-randomised trial to evaluate the implementation and effectiveness of a workplace mental health intervention in the state-wide police department of the south-eastern Australian state of Victoria. n. The primary aims of the intervention are to improve psychosocial working conditions and mental health literacy, and secondarily to improve mental health and organisational outcomes.
METHODS/DESIGN: The intervention was designed collaboratively with Victoria Police based on a mixed methods pilot study, and combines multi-session leadership coaching for the senior officers within stations (e.g., Sergeants, Senior Sergeants) with tailored mental health literacy training for lower and upper ranks. Intervention effectiveness will be evaluated using a two-arm cluster-randomised trial design, with 12 police stations randomly assigned to the intervention and 12 to the non-intervention/usual care control condition. Data will be collected from all police members in each station (estimated at >20 per station). Psychosocial working conditions (e.g., supervisory support, job control, job demands), mental health literacy (e.g., knowledge, confidence in assisting someone who may have a mental health problem), and mental health will be assessed using validated measures. Organisational outcomes will include organisational depression disclosure norms, organisational cynicism, and station-level sickness absence rates. The trial will be conducted following CONSORT guidelines. Identifying data will not be collected in order to protect participant privacy and to optimise participation, hence changes in primary and secondary outcomes will be assessed using a two-sample t-test comparing summary measures by arm, with weighting by cluster size.
This intervention is novel in its integration of stressor-reduction and mental health literacy-enhancing strategies. Effectiveness will be rigorously evaluated, and if positive results are observed, the intervention will be adapted across Victoria Police (total employees ~16,500) as well as possibly in other policing contexts, both nationally and internationally.

在本文中，我们介绍一项整群随机试验的方案，以评估澳大利亚东南部维多利亚州全州警察部门工作场所心理健康干预措施的实施情况和效果。该干预措施的主要目标是改善心理社会工作条件和心理健康素养，其次是改善心理健康和组织成果。
方法/设计：该干预措施是在一项混合方法试点研究的基础上与维多利亚警方合作设计的，将针对警局内高级警官（如警长、高级警长）的多阶段领导力辅导与针对不同职级警官量身定制的心理健康素养培训相结合。干预效果将采用双臂整群随机试验设计进行评估，12个警察局被随机分配到干预组，12个警察局被分配到非干预/常规护理对照组。将从每个警察局的所有警察成员中收集数据（每个警察局估计超过20人）。心理社会工作条件（如监督支持、工作控制、工作需求）、心理健康素养（如知识、帮助可能有心理健康问题的人的信心）和心理健康将使用经过验证的测量方法进行评估。组织成果将包括组织抑郁症披露规范、组织犬儒主义和警局层面的病假率。该试验将按照CONSORT指南进行。为保护参与者隐私和优化参与度，将不收集识别数据，因此主要和次要结果的变化将使用双样本t检验进行评估，通过比较两组的汇总测量值，并按整群大小加权。
该干预措施在整合减轻压力源和提高心理健康素养策略方面具有创新性。将严格评估其有效性，如果观察到积极结果，该干预措施将在维多利亚警方（约16,500名员工）中推广，也可能在国内和国际的其他警务环境中推广。
