Champions for health: a web-based acceptance and commitment therapy (ACT) intervention to enhance emotional wellbeing and encourage engagement with lifestyle behavioral changes

INTERVENTION: 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.
