Plain English Summary
Background and study aims
High alcohol consumption puts people at risk of poor health, and can also be bad for society. Since most adults in Sweden are in work, the workplace provides an important place to deliver an alcohol prevention programme. The overall aim of this study is to investigate potential effects of an alcohol prevention programme in workplaces.
Who can participate?
Organisations with above-average hazardous alcohol consumption and at least 100 employees. The employee participants must be aged at least 16 years and work at the organisation for at least 2 years after the organisation enters the study.
What does the study involve?
Organisations will be randomly allocated to one of two groups. Group 1 will receive training by Alna, a non-profit organisation that provides addiction prevention services. The training helps organisations to develop an implement an alcohol policy, and provides skills training for managers. Skills training aims to aid managers to identify early signs of hazardous alcohol consumption and increase managers’ confidence to address problems with alcohol early. Group 2 will receive the same training 1 year after Group 1. Managers and employees in all organisations are assessed using self-administered questionnaires at the beginning of the study, as well as 12 and 24 months later.
What are the possible benefits and risks of participating?
Managers will be able to identify early signs of hazardous alcohol consumption in the organisation and will be more likely to initiate early alcohol interventions. There is no direct physical or psychological harm to participating in the study.
Where is the study run from?
Department of Public Health Sciences, Stockholm University (Sweden)

Cluster randomised study of an alcohol prevention programme in the workplace
Acronym

Study hypothesis
To evaluate whether the alcohol prevention programme, which consists of organisational alcohol policy development and skills training among manager, leads to:
1. An increase in the reporting of inclination to engage in a conversation with an employee when suspicion and or worry about hazardous alcohol consumption arises
2. An increase in the employees' knowledge about where in the workplace one might get support in regarding hazardous alcohol consumption
3. An increased number of early interventions by managers (e.g. by engaging in a dialogue) to help employees with hazardous alcohol consumption or other types of harmful use
4. Managers and employees engaging in more sustainable alcohol use as measured by sum of Alcohol Use Disorder Identification Test (AUDIT) categories
5. Fewer cases of hazardous alcohol consumption among managers and employees as measured by AUDIT scores
6. Managers reporting being more confident in handling hazardous alcohol consumption in the workplace

Condition
Alcohol harm prevention delivered in the workplace
Intervention
Randomisation
The organisations were matched based on type of sector (e.g. hospitality sector) and size of organisations into blocks. Each block is allocated to either intervention or control group by a computer-generated program (random.org)
Intervention group
The first component focuses on implementation of organisational alcohol. Alna will assist managers to improve and implement organisational alcohol policy, where the policy is based on Alna’s previous experiences. This includes examples on responsibility and operational plan. The policy will be executed together with managers on three to four occasions, each lasting for approximately 2 h, depending on the availability of the organisation.
The second component of the programme is skills development training, with the purpose of helping managers to be able to identify early signals of hazardous alcohol consumption and to be able to act upon signs of behaviours that may lead to adverse effects for both employees and the organisation. Managers will attend two training workshops directed by Alna, which lasts for 3.5 h per session. The workshop will cover various topics regarding addiction, prevention and dialogues about hazardous use of alcohol. At the end of the second session, a ‘checklist for managers regarding alcohol use’ will be introduced. This checklist includes topics such as: different types of alcohol use; prevalence of alcohol use; risk factors; tools to start a dialogue with employees; signs to identify hazardous alcohol use; the role of workplace culture and policy in alcohol consumption; roles and responsibility of the organisation; implementation checklist to understand purpose of the intervention; and discussions on ambiguous cases.
Control group
Organisations that have been allocated to the control group will be placed on a waitlist and will continue their usual practice. Control organisations will receive the same prevention programme as the intervention group after 12 months follow-up.

Primary outcome measure
Managers' self-rated inclination to initiate early alcohol interventions by engaging in a dialogue with employees who may have hazardous alcohol consumption, measured using a 5-point Likert scale at baseline, 12- and 24-months follow-up periods
Secondary outcome measures
The following will be assessed at baseline, 12- and 24-months follow up, using self-administered questionnaires for managers and employees. Questionnaires will investigate:
1. Knowledge about where to support regarding hazardous alcohol consumption
2. Whether hazardous alcohol consumption has made them worried or made them take action
3. Change in alcohol consumption
4. Level of alcohol problems among managers and employees
