Abstract
Project Summary
Sedentary behavior (i.e., sitting) has emerged as an important risk factor for chronic diseases and mortality.
Working adults accumulate large volumes of daily sedentary time. Sit-stand workstations are now the fastest
growing employee benefit yet evidence-based interventions are not being implemented to support their use.
Our team has recently completed the largest and most definitive efficacy trial on the impact of an intervention
designed to support use of sit-stand workstations and reduce sedentary behavior in the workplace. Stand &
Move at Work (SMW) is a multicomponent, social-ecological behavioral intervention that we tested in 24
industry, government, and academic worksites (N=630 workers). 12-month intervention effects included: (a)
sustained reductions in sedentary time (~60 min/8 h workday); (b) reduced body weight and improved chronic
disease risk factors among those with high baseline risk; and (c) reduced musculoskeletal pain. We are now
proposing a new trial that tests the role of expert facilitation to enhance effectiveness and implementation of
the SMW intervention. We used the Integrated - Promoting Action on Research Implementation in Health
Services (iPARIHS) framework to inform our new trial through: (a) organizing our implementation outcomes
from our efficacy trial; (b) conducting industry-based discovery interviews; and (c) piloting our enhanced
implementation strategy in several new worksites. This current proposal describes a 2-arm group-randomized
hybrid effectiveness-implementation (type 2) trial to test the effectiveness of SMW for reducing sedentary time
in the workplace, and to test an implementation strategy (i.e., expert facilitation) for improving implementation
fidelity. Worksites (N=24) will be observed over 3 months of sit-stand workstation use only, and will then be
randomized to 12 months of either: (a) SMW (web-delivered); or (b) SMW+ (web-delivered + expert
facilitation). Our dual primary outcomes will be reductions in objectively-measured sedentary time
(effectiveness) and intervention fidelity (implementation) over 12 months. Because facilitation increases
intervention cost, we will also assess incremental cost benefit of our interventions (secondary aim). Finally, we
will explore fidelity as a driver of effectiveness, examine within-worksite differences in sedentary time pre- and
post- implementation, and measure organizational sustainability of effectiveness and implementation at 24
months. The potential health benefits of sit-stand workstations and associated worksite health promotion
programs will not be realized in the workforce at large until we test the most effective and efficient way to
implement evidence-based interventions. This project is among the first initiatives to address this growing trend
in worksite health, and will answer important questions related to effectiveness, implementation, and cost
benefit. Optimal strategies for delivering the SMW intervention will be identified and new knowledge will be
generated on how facilitation can enhance implementation fidelity of workplace health initiatives, both of which
will increase the public health impact of evidence-based interventions.
