Penn State Hershey Sitting and Health Study

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to: (a) evaluate if a desk-based elliptical device can help employees to increase their daily physical activity without compromising work productivity; and (b) evaluate the effects of different types of incentives for pedaling the desk-based elliptical device on employees' pedaling quantity over a one-month intervention period. The study will involve placing a compact elliptical device (provided at no cost by the research team) under employees' desk at Penn State Hershey Medical Center/College of Medicine. Data evaluating the effects of the elliptical device on work productivity will be obtained from both employees and the employees' supervisors.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Usual Delayed Compensation, Money<br>Will receive delayed monetary compensation with Amazon gift card, non performance-contingent. | Behavioral: Desk-based pedaling device and pedaling incentives provided<br>* Varying types of incentives, equivalent in monetary value, will be randomly assigned across the 6 arms to promote regular desk-based pedaling. A free desk-based pedaling device will be provided. Effects on amount of desk-based pedaling and work productivity will be evaluated.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Worker Productivity | Self-report assessments of worker productivity. The assessments will ask about work productivity in the prior 4-week period. | Baseline (1 month period prior to program start) and post-program (immediately after program ends) | 
| Elliptical Device Pedaling Quantity | Objectively-measured pedaling quantity from elliptical device | 1 month (4 weeks) during pedaling program | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| User satisfaction, process evaluations | Satisfaction with intervention condition | Post-program (immediately after program ends) | 
| General (non-desk pedaling) physical activity | Self-reported physical activity | Baseline (1 month period prior to program start) and post-program (immediately after program ends) |
