Stand & Move at Work II: Effectiveness and Implementation of a Worksite Wellness Program
(SMWII)
What this study is about
This is a 2-treatment group$1 group-randomly assigned 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.
View original scientific description
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.
Interventions

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
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
Where
- Phoenix, Arizona

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
