Plain English Summary
Background and study aims
Globally prevalence rates of common mental disorder (CMD) such as anxiety and depression are high. In the UK estimated population incidence rates are between 4-10%. The individual and economic cost is significant. In the UK, the estimated costs of mental health problems are £70-100 billion each year and account for 4.5% of GDP. Thus prevention and early intervention make economic sense.
In contrast, positive mental health and wellbeing are associated with benefits across health, social and economic domains. WHO report the following benefits: improved overall functioning, better lifestyle choices, greater educational attainment, higher income and higher productivity. Positive wellbeing has been proposed as a protective factor which may contribute to positive physical health and associated reductions in mortality. For example, one study found positive wellbeing to be associated with reductions in cardiovascular mortality in a healthy population. Thus interventions focused on improving physical health and wellbeing could promote positive aspects of health and lead to numerous health benefits at a population level.
Barriers to access
Patient and public access to psychological treatments to treat CMDs is often limited by long waiting lists, inadequate numbers of trained professionals able to meet the high demand for face-to-face therapies and social stigma attached to mental health in general. The experience of social stigma causes many not to initiate or continue effective treatment. Web-based interventions do not require users to identify themselves, the anonymity afforded through these platforms may encourage higher rates of personal disclosure and thus could be therapeutically beneficial.
As a result internet and web-based interventions provide a cost-effective means by which to deliver health promotion and wellbeing interventions.
Thus the current study aims to conduct a cluster randomized control trial (RCT) to evaluate the impact of an acceptance and commitment therapy (ACT) based emotional wellbeing intervention on; lifestyle behaviour change; adherence and engagement with lifestyle behaviour change modules and emotional wellbeing.
Who can participate?
Members of staff at recruited organizations who are able to access the website
What does the study involve?
This evaluation will be achieved by inviting staff at selected organizations to take part in a 12-week staff health challenge. Participants will be able to take part by signing up to a website called Champions for Health. They will have the opportunity to choose a health challenge to take part in that is suited to their health needs and will be randomized to receive access to the emotional wellbeing intervention or not.
What are the possible benefits and risks of participating?
It is anticipated that participation in the study could bring benefits at individual level in regards to improved physical health through the adoption of positive lifestyle behaviour change. In addition to this it is anticipated that positive benefits will be seen to those randomised to receive the wellbeing intervention who engage with it for the 12 week duration.
There are no anticipated risks to participants who consent to take part in this study.

Emotional wellbeing and lifestyle behaviour change
Participants are required to register on the study website, provide consent and complete a study registration form with baseline health and wellbeing questionnaires. They will then be automatically allocated to either the control or intervention arms based on the information they provide about their employing organization and site location within the organization. Participants are randomized at a cluster level, with each different site within the SBUHB health board (at which participants are employed) randomly allocated to either the intervention or the control arm. The researcher is blinded to this allocation. The website programmer used a randomly generated sequence to pre-program the website to allocate participants accordingly.
The intervention arm receives an emotional wellbeing intervention based on acceptance and commitment therapy (ACT). The intervention is available to participants via the Champions for Health website for 12 weeks and has been designed to be accessed on a weekly basis. However, participants will have access to all 12 weeks immediately and are free to navigate the resources as they wish. Each week contains an ACT skill to learn, practice exercises and an interactive motivational goal-setting tool.
The control arm participants have no access to the wellbeing intervention.
Both control and intervention participants will have access to five lifestyle behavior change modules via a health promotion website. The baseline health and wellbeing questionnaires are repeated for all participants at 12 weeks.
Primary outcome measure
Emotional wellbeing measured by the Warwick-Edinburgh mental wellbeing scale (WEMWBS) and the patient health questionnaire for depression and anxiety (PHQ4) at baseline and 12 weeks
Secondary outcome measures
Psychological inflexibility and experiential avoidance measured by the Acceptance and Action Questionnaire-Revised (AAQ-II) at baseline and 12 weeks

IPD sharing statement:
The datasets generated during and/or analyzed during the current study will be available upon request from Menna Brown via email on email@example.com. The raw data collected in the study without identifying data will inlclude, pre and post wellbeing scores (where completed), enrolment to modules and engagement with modules. This data will be available until completion of the PhD project it is linked to (which is anticipated in July 2021). It will be made available in an Excel spreadsheet. Consent from participants will be obtained.
