This is a 2-arm group-randomized hybrid effectiveness-implementation (HEI type 2) study to test an evidence-based intervention (EBI) known as Stand & Move at Work(SMW) to reduce sedentary time in the workplace, and to test the role of expert facilitation (SMW+) for improving intervention fidelity.

Primary Aim: To assess worksite-level reduction in sedentary time and intervention fidelity over 12 months Secondary Aim: To assess cost effectiveness of the intervention at 12 and 24 months

Worksite-Level Inclusion Criteria:

• More than 80% of employees work full time (30+ hours per week).
• At least 45 employees in the worksite with sit-stand workstations working at least three days per week
• Occupations require primarily desk-based work (e.g., computer- and telephone-based)
• Willing to allow the researchers to distribute online research surveys to all employees in order to allow the program to be evaluated.
• Allow 30 randomly selected individuals to wear an activity monitor in several 7-day intervals across two years.
• Willing to be randomized to either intervention.
• Willing to identify one or more worksite champions to implement the Stand & Move at Work™ program.

Worksite-level exclusion criteria:

• Involved in previous interventions to reduce sitting and increase standing and moving at work in the last 24 months.
• Involved in the Stand and Move I intervention.
• Another worksite within the same organization is participating in the program and contamination across those worksites cannot be avoided.

Employee-level inclusion criteria:

• 18 years or older
• Willing to provide informed consent

Access to databases and associated software tools generated under the project will be available for educational, research and non-profit purposes. Such access will be provided using web-based applications, as appropriate. Publication of data shall occur during the project, if appropriate, and at the end of the project, consistent with normal scientific practices. Research data to document, support and validate research findings will be made available after the main findings from the final research data set have been accepted for publication. Such research data will be de-identified to prevent the disclosure of personal identifiers.

Protocol and analysis plan will be available for sharing in 2022. Analytical code and data sets will be available for sharing following publication of the primary and secondary outcome papers.
