Breaking barriers: using the Behavior Change Wheel to develop a tailored intervention to overcome workplace inhibitors to breaking up sitting time
Abstract Background The workplace is a prominent domain for excessive sitting. The consequences of increased sitting time include adverse health outcomes such as cardiovascular disease and poor mental wellbeing. There is evidence that breaking up sitting could improve health, however, any such intervention in the workplace would need to be informed by a theoretical evidence-based framework. The aim of this study was to use the BCW to develop a tailored intervention to reduce workplace sitting in desk-based workers. Methods The Behaviour Change Wheel (BCW) framework with the COM-B (Capability, Opportunity, Motivation – Behaviour) theoretical model at the hub was used to guide the process of intervention development. Twenty-five office-based workers with high amounts of self-reported workplace sitting were interviewed using questions developed with the TDF. Results The majority of participants felt they were physically capable of breaking up their sitting time, while all participants stated the importance of having knowledge regarding both guidelines for sitting time and the consequences of excess sitting. A supportive organisational culture was identified as important, along with the need for environmental context and resources. Both reflective and automatic motivation were identified as potential targets for behaviour change interventions. Seven intervention functions and three policy categories from the BCW were identified as relevant. Finally, 39 behaviour change techniques (BCTs) were identified as potential active components for an intervention to break up sitting time in the workplace. Conclusions The BCW framework provided a systematic process for developing a theory-driven and co-created intervention packages that can be used to break up and decrease prolonged sitting in office workers. Intervention designers should consider these BCW factors and BCTs when developing interventions to break up workplace sitting.
