A growing body of recent evidence links high volumes of sitting time to risk of major chronic diseases and premature mortality [1]. Only very high volumes of moderate- to vigorous-intensity physical activity (≥60 min per day), which are achieved by less than 5% of the population, have been seen to attenuate the risk of death associated with high sitting time, according to a recent meta-analysis using data from over 1 million adults [2]. Correspondingly, the national physical activity and health guidelines have a dual message of move more and sit less [3].

Sitting time can be strongly contextually driven, dictated by the environmental and social settings in which it occurs [4]. For many working adults, the majority of daily sitting time is accrued in the occupational environment [5], with desk workers spending on average 70% to 80% of their working day sitting [6]. Much of this sitting time is accrued in prolonged, unbroken bouts of 30 min or longer [6]: a pattern that potentially places them at increased risk for poor cardiometabolic [7,8] and musculoskeletal [9] health. As the proportion of industry sectors that involve desk-based work has increased substantially in recent decades, with further increases being forecast [10], the desk-based workplace has been identified as a key setting in which to target reductions in prolonged sitting time [11]. The relevance for occupational health and safety, as well as for public health, of addressing this behavior is reflected in Safe Work Australia’s acknowledgment of prolonged workplace sitting as an emergent work health and safety issue [12].

Within this context, the Stand Up Australia collaborative research program was developed [13]. Its aim was to understand how to reduce prolonged sitting time in the workplace and the benefits that may ensue, with the explicit intention of informing translation into practice. A series of pragmatic, researcher-led intervention trials, with participant numbers ranging from 32 to 231, assessed the effectiveness of different strategies (organizational, and environmental, individual; alone or in combination) to support workers to stand up, sit less, and move more in the workplace, with a particular focus on the desk-based workplace [6,14-18]. This Stand Up Australia program of research demonstrated that it is feasible and acceptable to introduce strategies within desk-based workplaces to create a dynamic work environment (which encourages more movement, more often) and to do so without detrimentally impacting on productivity [19]. Such strategies can lead to reductions in workplace sitting time that are substantial (eg, >1.5 hours per 8 hours at the workplace [14]) and sustained (≥12 months [6]). These findings have further been corroborated by other research groups [20,21] and supported by several systematic reviews [22-26]. With a body of evidence on the feasibility and benefits of reducing workplace sitting time, there is now a strong demand for advice, assistance, and support in implementing evidence-based strategies into policy and practice. However, tools and resources to support such implementation at scale do not exist. To meet this appetite, the BeUpstanding Champion Toolkit was developed collaboratively based on evidence from Stand Up Australia and the broader sedentary behavior and health research field.

The no-cost, web-based BeUpstanding Champion Toolkit [27] provides a step-by-step implementation guide and associated multimedia resources to enable a workplace champion to deliver the intervention program (BeUpstanding) within their own work team, independent of input from external expert stakeholders (ie, researchers) [13]. In line with better practice [28] and existing frameworks for program delivery [29], the program is underpinned by a participative and collaborative approach, tailoring of strategies to the organization, visible organizational support for the program, a strong evaluation framework, and communication of program outcomes, including through automated reports. The program allows for repeated delivery, with champions encouraged to continue to make sustainable changes and build on previous success within their work teams. However, in a key distinction from the researcher-led Stand Up Australia interventions, BeUpstanding was designed specifically for delivery by workplace champions (ie, dedicated staff members). A train-the-champion approach was used as workplace champions have been shown to be critical to the success of workplace interventions, acting as role models and drivers for staff participation and work team change [30-32]. This approach also facilitates wide-scale delivery as the workplace (rather than the research team) is responsible for program delivery.

The translation of what has been learned from the Stand Up Australia intervention trials to the BeUpstanding program has involved multiple, iterative phases [13]. These phases have been underpinned by the key principles guiding dissemination of broad-reach health behavior programs [33], including partnerships with key stakeholders, ensuring fit of the program with the organizational goals, integration of outcomes important to informing funders and advancing science, systematic tracking of the resources needed for implementation and intervention, and the maintenance of program fidelity while being flexible and responsive. Central to this has been the development of the technology platform underpinning the toolkit. This platform has not only enabled the evaluation of the effectiveness of the program but has also facilitated insights into the levels of engagement with the program components.

Phase 1, described in detail elsewhere [13], involved initially creating BeUpstanding from the Stand Up Australia interventions. This development occurred in close collaboration with government occupational health, safety, and well-being partners to ensure strong alignment with existing workplace health, safety, and wellness frameworks. It was also developed with consideration of the partner requirements (optimization criteria [34]) that the program have the following attributes: low cost or no cost to workplaces, feasible for workplaces to deliver, scalable, and compatible with existing programs, including the frameworks and language used. These considerations, and the learnings from the preceding trials, collectively led to the “train-the-champion” approach, the use of a web-based toolkit, and the framing of the intervention around the three stages commonly used in government workplace health, safety, and well-being programs (ie, Plan, Do, and Review). The low cost/no cost requirement also meant that sit-stand workstations, which have been shown to effectively reduce workplace sitting (particularly when part of a multicomponent approach) [35], are not a core component or requirement for participation in the program.

Phase 2 involved a quantitative and qualitative evaluation of a small-scale pilot of the beta (test) version of the toolkit [36]. Seven teams of workers in mostly desk-based occupations were included, collectively covering diverse sectors: blue and white collar sectors; government and nongovernment; metropolitan and regional; and small, medium, and large organizations. Overall, the pilot phase demonstrated that the BeUpstanding Champion Toolkit (beta version) was feasible and acceptable for use by workplace champions and that the program delivered through the toolkit was effective at raising awareness, building a supportive work team culture, and reducing workplace sitting time [36,37]. The piloting of the toolkit showed an average reduction in self-reported workplace sitting time of 34 min per 8-hour workday (95% CI −51 min to −14 min) following approximately 3 months of intervention. This level of effect on sitting time has previously demonstrated significant improvements in some indicators of cardiometabolic health [38]. Champions typically spent 30 min to 1 hour per week on the program during this pilot phase [36]. Notably, interviews with the workplace champions 12 months after initial implementation found that teams continued to support the strategies, including through policy development (eg, centralized printers) and dedicated resource funding (eg, purchase of sit-stand desks) [37].

The learnings from phase 2 then informed the optimization of the toolkit (phase 3) to ensure it was fit for purpose for an implementation trial. Phase 3 included the development of a web-based, user-friendly onboarding system (to both promote the toolkit and enable champions to sign up for the toolkit) using human-centered design principles [39], enhanced backend capacity of the toolkit (to facilitate multiple simultaneous users), development of an embedded survey management and data collection system, and enhanced graphic design.

This updated version was tested via a soft launch of the program, with over 100 champions enrolling in the program during this period (September 2017 to May 2019). Several key learnings were gained from these early adopters. Firstly, despite the minimal promotion during the soft launch, there was strong uptake of the program, with champions enrolled from throughout Australia and across multiple sectors. This provides strong indication that there is an industry need for a program such as BeUpstanding. Secondly, workplaces were at different stages of readiness, with some champions wanting only to use select program materials (eg, posters) to help raise awareness of the importance of sitting less and moving more, whereas others were ready to run the full program. Thirdly, there was wide variation in how champions engaged with the toolkit, measured by the number of log-ons, with some champions repeatedly logging on throughout the program and others logging on rarely and/or infrequently. Finally, we found that although the toolkit was designed well for delivery by a single champion to their team of workers, it was not sufficiently flexible for larger organizations with large workplaces. It was identified that in a number of instances, there was a combined team formed of several teams led by champions who each adopted more nuanced roles (such as oversight without necessarily directly intervening on staff). Adaptations to the toolkit were made accordingly to suit a range of toolkit user roles.

These key learnings, which were complemented by discovery interviews and in-depth case studies with select participants (chosen to capture insights across sectors, locations, organizational size, and toolkit engagement), were used to inform further optimization of the program and toolkit and the protocol development for the national implementation trial of the BeUpstanding program (phase 4). Adaptions were done taking into account considerations from multiple perspectives, including the end users, the partners, the researchers, and the financial constraints [34,40]. The aims of this paper are to describe the current version of the BeUpstanding program and the methods and protocol for evaluating the BeUpstanding program in the context of a national implementation trial.

The BeUpstanding program is designed to be implemented within a workplace (broadly, defined as from one organization, with the same workplace policies) by a champion to their work team (colocated members of the workplace) of which the champion is also a member. Larger workplaces may run BeUpstanding by having several champions deliver the intervention to their teams concurrently. For the purposes of accrual targets and statistical analyses, these multiple teams are counted as one combined team. There are three phases to the program (plan, do, and review) and five steps as part of the BeUpstanding program (Table 1). Each step has associated tasks for the champion to complete, noting that not all tasks may be relevant for all champions because of their workplace and/or work team requirements. The toolkit provides information (training) on the purpose of each step and task and resources to support the implementation of each task. As part of the implementation trial, champions will receive further training via coaching calls. The most critical step of the program is the staff workshop (Step 3.3). This step is designed to get everyone in the work team on board in terms of why and how the team can BeUpstanding together. In line with participatory design principles [41], work teams are encouraged to collectively choose three strategies to stand up, sit less, and move more to implement, based on which best suit their team’s needs and existing culture. Some strategy suggestions, according to the hierarchy of control [42], are provided within the toolkit (Table 2 shows a modified version of this resource). Staff members may choose to implement more than the three team strategies. Alternate suggestions for raising awareness and enabling this collective decision making are provided when running the workshop with all staff at the same time is infeasible (eg, because of shift work). Champions are encouraged to run the BeUpstanding program for 8 weeks from the launch, sending emails and rotating posters on a weekly basis for the first 4 weeks and fortnightly for the second 4 weeks, with the posters and emails organized according to the recommended schedule. Collectively, the workshop, posters, and emails are designed to raise awareness of the benefits of sitting less and moving more, build a supportive culture for change, and encourage participants to take action to achieve this change. Owing to the participative nature of choosing the strategies, and the ability of the champion to tailor the emails, the actual intervention program is bespoke for each work team. The champion is responsible for running and evaluating the program, which includes sending all staff in their work team links to the web-based evaluation surveys (Task 2.2; Task 5.1). Champions are also encouraged to hold staff events (eg, a lunchtime walk and wear your sneakers to work day) and to celebrate and promote individual and whole-of-team success. All staff in the work team will potentially be exposed to the intervention messages (posters and emails), and all staff can choose their level of involvement with both the strategies and the evaluation components. The toolkit encourages champions to run BeUpstanding (or components of thereof) with their team on an annual basis.

The aim of this study is to evaluate the BeUpstanding program in the context of a national implementation trial. The research questions to be answered are those important to informing the dissemination (phase 5) [13]: in particular, who takes part in the program, how the program was delivered, did the program work (and for whom did it not work), and how much did it cost. The RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) Framework [49] will be used to guide the evaluation, with assessment of the adoption/reach of the program (the number and characteristics of work teams and participating staff), program implementation (completion by the champion of core program components), effectiveness (on workplace sitting, standing, and moving), and maintenance (sustainability of changes). The implementation trial is funded by a National Health and Medical Research Council (NHMRC) of Australia Partnership Project Grant (number 1149936), which includes cash and/or in kind support from the five partners (see below). Ethical approval was gained by The University of Queensland Human Research Ethics Committee (approval number 2016001743). The trial was prospectively registered on May 12, 2017 (ACTRN12617000682347), before the soft launch of the program and last updated on the June 11, 2019. All participants will provide informed consent to participate.

A single-arm design will be used to evaluate the BeUpstanding program, with repeated cross-sectional evaluations at preprogram (0 weeks), end of program (approximately 8 weeks; primary endpoint), and at 9 months postprogram (approximately 12 months post sign up). Repeated cross-sectional evaluations provide a flexible evaluation protocol [50] that can assess change within retained members of the baseline survey cohort over time and more general time trends (owing to both changes over time within participants and some fluidity in work team membership, such as because of workforce turnover).

On the basis of data reported by the champion as part of the web-based registration process, eligible Australian-based work teams will be those who had not run the BeUpstanding program previously with a minimum of five staff members, job roles or tasks that predominantly involve desk-based work, and a staff member willing to perform the duties of a workplace champion. Champions must also be planning to run the program within the recruitment window. For large organizations, including those located across numerous sites, multiple work teams from the one organization will be eligible to participate. These will be treated as a single combined team when the intervention is concurrent and within a workplace as per the criteria; otherwise, separate teams will be permitted to participate. Each champion will invite all employees within their work team to participate in the program and its evaluation. All workers invited will be considered eligible unless they indicate within the staff survey that they are unable to currently walk or stand for at least 10 min without an assistive device or requiring assistance from another person. Accrual targets have been set at 50 or more work teams per priority sector and 10,000 or more staff exposed to the program in total (see sample size). Performance against these accrual targets will be reviewed at the quarterly steering committee meetings, with the promotion and marketing plan adapted as required to ensure targets are met.

The implementation trial will be conducted in partnership with five Australian workplace health and safety policy and practice organizations: Safe Work Australia, Comcare, Queensland Office of Industrial Relations, The Victorian Health Promotion Foundation (VicHealth), and Healthier Workplace Western Australia. These organizations are responsible for developing, implementing, and/or promoting Australian workplace health and safety policy. Each partner has committed to endorse and promote the toolkit across their relative jurisdictions. Desk-based employees from a wide cross-section of industries will be targeted, inclusive of sectors collectively identified as priorities by the partners (small business, regional, call center, blue collar, and government). To ensure efforts are coordinated, a detailed action-mobilization plan will be developed with the partners. The plan, which will include an annual promotional push via an awareness raising event, will build on and coordinate with existing communication channels and resources from the partners and participating institutes, including social media, web links, email listservers, newsletters, workplace health promotion and occupational health networks, conferences, and workshops.

The BeUpstanding website [27] is designed for workplace champions; however, anyone can freely sign up to use the BeUpstanding Champion Toolkit via the registration survey (sign up form) on the BeUpstanding website. At signup, a user identifier is generated and a welcome email is automatically sent that includes details regarding the implementation trial. To unlock the toolkit contents, the user is required to complete the champion profile survey and is asked to nominate their intended role as a toolkit user (which might be a workplace champion or another nondelivery role, such as senior decision maker, interested staff member.). Following completion of this survey, champions with work teams that appear eligible for the implementation trial will be invited via a phone call from the research team to participate in the implementation trial, with recruitment continuing until accrual targets are met. This phone call with the champion will be used to confirm the eligibility of the work team for involvement in the implementation trial, ascertain from the champion the likely readiness of the work team to participate in the program, and confirm the contact details of the workplace champion (and an alternate contact). Those eligible and indicating interest in trial participation will be sent additional information on trial participation requirements, namely, confirmation of organizational support to run the five-step BeUpstanding program and commitment to the implementation trial evaluation components. The champion’s electronic consent to the trial will be required before implementation trial enrolment.

Outcome and process data and the characteristics of the workplaces, champions, and staff taking part in the implementation trial will be collected via the dedicated, stand-alone BeUpstanding website (Registration Survey; Champion Profile Survey; Workplace Audit; Staff Surveys —baseline, end program, and maintenance; Strategy Survey; Program Completion Survey; and toolkit analytics) and by the project manager (implementation checks and qualitative interviews), as outlined in Figure 1. Champions will be required to provide informed web-based consent for their data to be used by the research team before completing the Champion profile survey, with further consent required to participate in the implementation trial. Staff will be required to provide informed consent for their data to be used by the research team before completing each of the staff surveys. Data for staff are anonymous; however, to enable participants to be tracked across data collection points, each staff survey includes three questions designed to generate a unique (but anonymous) identifier for the staff participant when used in combination with the champion ID: day of the month they were born on, first letter of mothers first name, and last three digits of their mobile number.

The promotional activities undertaken by partners will be recorded at the 6-weekly partner meetings, with their impact on registrations tracked through the analytics in the toolkit website. The promotional pathways will be tracked through URL identifiers, through Google Analytics, and via champion self-reporting through the champion profile survey. Factors potentially influencing uptake and engagement with the program (eg, number of teams within a workplace participating in the program) will also be tracked via the registration survey and implementation checks. To ensure minimum data accrual targets are met, the project manager will follow up with champions (via email/phone) where necessary to encourage and support data collection.

The project manager will have a minimum of five telephone contacts with the champion across the implementation trial evaluation: (1) recruitment, (2) confirmation of consent and explanation of next steps, (3) as soon as possible following the staff workshop, (4) at the end of the program, and (5) 9 months after the end of the program. Focus groups will be undertaken with a subsample of consenting staff from participating teams (n was approximately 15) at the end of the program to assess their perspectives on the processes and outcomes of the program. A mix of teams who made small/no, midrange, and large improvements and from different sectors will be purposively sampled, with focus groups conducted either in person or on the web via a virtual meeting room.

Outcomes and measures are shown in Table 3, along with the relevant RE-AIM indicators and measurement tools. As adoption logistically occurs before reach, RE-AIM is reported as ARIEM.

As an implementation study, there are some inherent limitations. The use of a single-group, pre- to poststudy design is primary among these. A randomized controlled trial (RCT) design was considered, as this design would provide more robust effectiveness outcomes. However, an RCT would not provide better data for the reach, adoption, and implementation outcomes. It was also unclear how to conduct an RCT while preserving the key intervention model being tested of a workplace champion delivering and evaluating the intervention, particularly given the BeUpstanding toolkit is already live and freely available. Experience from the pilot and early adopters phases (phases 2 and 3) led us to expect that we would not be able to recruit champions willing to act as controls and complete all the evaluation but receive none of the intervention (even if they received a delayed intervention). Even the evaluation requires a reasonable amount of effort on the part of the workplace champion: researchers have no contact with the staff. Anyone can sign up to the toolkit (including potential control organizations) meaning contamination would be very difficult to control in those who sign up and are allocated to the control arm. We would also need to expend significant resources tailoring the toolkit to perform the evaluation but not the delivery intervention functions for those champions whose teams were allocated to a control condition. Therefore, on balance, it was considered that the pre-post design was the most appropriate to evaluate the implementation trial.

Providing a menu of options and supporting work teams to collectively choose which intervention strategies will work best for them is a key strength of the program, with findings likely to provide key insights into possible higher order strategies to effectively support workers to sit less and move more [68], but this approach does mean that findings across work teams will not necessarily be directly comparable. It also means that strategies known to successfully achieve shifts in workplace sitting time, such as the use of sit-stand workstations as part of a multicomponent approach [35], will not necessarily be implemented by work teams. Furthermore, for some individuals, the strategies chosen by the team to BeUpstanding may not be appropriate for them personally. However, the primary questions to be answered are about the uptake, implementation, and costs of wide-scale implementation and the outcomes that can be achieved in this context; questions that are being answered through RE-AIM—a widely used framework for understanding dissemination [49]. Further strengths of the study include its pragmatic design. The toolkit readily facilitates uptake and delivery with minimal follow-up required from stakeholders. The program is also designed to be easily integrated into existing wellness, health, and safety initiatives. This presents an innovative model that has a high likelihood of being able to be generalized more broadly. Importantly, all five industry partners are ideally suited to use trial findings to directly shape and deliver national and international workplace policy and practice.
