Plain English Summary
Background and study aims
Prolonged sitting time contributes to health outcomes such as poor mental health, musculoskeletal disorders, diabetes and cardiovascular disease. Sedentary behaviour is the norm in contact centres and some employees report spending up to 95% of their shift in a sedentary position. The UK is home to some of the largest contact centres in Europe, employing 4% of the workforce (about 1 in 25 employees). Contact centres often have rigid layouts and a specific culture whereby staff have low autonomy and high productivity targets. Although there have been interventions to reduce sitting time in a range of workplaces, few have been developed specifically for contact centres. This lack of specific interventions for an ‘at risk’ workforce means they may fall behind other employees when it comes to reducing sedentary activity. Researchers have developed a multi-level intervention to reduce sitting time in contact centres, called Stand Up for Health (SUH). The intervention is co-produced with employees and activities are developed that are specific to each contact centre. It promotes ownership, acceptability, transferability and sustainability. It has been running for a year in a pilot centre in Edinburgh (Ipsos Mori Edinburgh, see video http://www.scphrp.ac.uk/stand-up-for-health/) and is gaining momentum there, with new activities being added by the staff. The researchers now wish to assess its feasibility and acceptability in other contact centres, and whether they can undertake a large trial in the future. This study aims to implement SUH in 10 contact centres to test: a) whether it is feasible and acceptable to recruit contact centres and their employees and collect the data required; b) does it work in the way it is intended to do, or does it need modifying; c) does it appear to be showing some evidence of effectiveness which is worth investigating in a larger study.

What does the study involve?
Contact centres are randomly allocated to receive the intervention at different time points, and are assessed to see who is taking part, is it being implemented, and is it working as intended. The results are used to make changes to the intervention as needed. The main outcome is whether it is feasible to undertake such a trial in contact centres, and to see if there is change in workplace sitting time. Other outcomes include mental wellbeing at work, musculoskeletal disorders, productivity and job satisfaction. The intervention begins with a ‘workshop’ that takes place at a contact centre, where staff have a chance to try out, suggest and vote for the activities they want to try out. They also describe the environment, location, existing equipment and other assets which are then used to plan the activities. Some small pieces of equipment are available to loan and try out through the SUH research team. These activities are then converted into an action plan to be implemented over a number of weeks. A key intervention component is the creation of a SUH implementation group made up of all levels of contact centre staff who ensure that activities are implemented. At the end of the intervention period a second workshop is held to check in as to which activities have worked and which haven’t. Further prioritisation and choosing of future activities is undertaken. A website is developed with useful resources and opportunities for the contact centres to blog/share their experiences and create a community of SUH contact centres.
What are the possible benefits and risks of participating?
Benefits are that contact centres have a chance to implement policies and practices which may impact positively on their workforce. Risks are that the workforce do not want to participate.

Sedentary behaviour in contact centres
The unit of randomisation is contact centres. A computer-generated block randomisation algorithm will be used to randomly allocate each contact centre to start the intervention at one of five timepoints, three months apart. Randomisation in this way allows the researchers to introduce the intervention to each site in an unbiased way unrelated to time or the particular circumstances of each site. It also helps ensure there is an approximate balance on average across all the intervention start times in terms of participant or contact centre characteristics. The total duration of the intervention is around 3 months. In order to minimise cost and participant burden for this trial, and since the main purpose of the trial is to test study processes and procedures, data will only be collected at a maximum of three occasions per site: at the end of the control period, and at 3 and 6 months after the end of the intervention in each site. Sites 1 and 6 will not have a control period, and sites 5 and 10 will not have a post-intervention period, in order to minimise the duration of the study for which there is no concurrent vertical comparison between control and post-intervention periods. To increase the response rate, participants will be paid a small amount (£5 end of the control period and £10 for 3 months data) for taking part in data collection.
The initial stage of the intervention includes a ‘workshop’ that takes place at a contact centre, where staff have a chance to try out, suggest and vote for the activities they want to try. They also describe the environment, location, existing equipment and other assets which are then used to plan the activities. Some small pieces of equipment will be available to loan and try out through the SUH research team. These activities are then converted into an action plan to be implemented over a number of weeks. A key intervention component is the creation of a SUH implementation group made up of all levels of contact centre staff who ensure that activities are implemented. At the end of the intervention period a second workshop is held to check in as to which activities have worked and which haven’t. Further prioritisation and choosing of future activities is undertaken. A website will be developed with useful resources, and opportunities for the contact centres to blog/share their experiences and create a community of SUH contact centres.
Primary outcome measure
Sedentary time in the workplace (objectively measured), measured using activPAL™ devices, which are small, thigh-worn devices for assessing posture and is the preferred measurement instrument for assessing changes in occupational sitting. Participants wear the device continuously for seven days (during waking/sleeping hours and water-based activity) to provide adequate reliability. Following recommended procedures, the researchers will isolate and determine changes in accumulated sedentary time whilst at work. Data will be collected at a maximum of three occasions per site: at the end of the control period, and at 3 and 6 months after the end of the intervention in each site. Sites 1 and 6 will not have a control period, and sites 5 and 10 will not have a post-intervention period, in order to minimise the duration of the study for which there is no concurrent vertical comparison between control and post-intervention periods.
Secondary outcome measures
1. Sedentary time in the workplace subjectively measured using the Occupational Sitting and Physical Activity Questionnaire (OSPAQ)
2. Overall sedentary behaviour objectively measured using activPAL™ devices to assess changes in prolonged sitting time in the workplace (bouts of ≥ 30 minutes), total sedentary time (i.e. including time outside the workplace such as at home and leisure time), workplace and total standing time, and workplace and total sit-to-stand transitions
3. Physical activity assessed objectively using activPAL™ devices to assess changes over time in the workplace and total stepping, and subjectively using the International Physical Activity Questionnaire (long), last 7 days self-administered
4. Objective measures of productivity including: absenteeism, presenteeism, call handling time, time spent talking, time spent on hold, time spent wrapping up a call, attendance, or sick leave. Subjective measures assessed using the Utrecht Work Engagement Scale and other measures in similar studies
5. Mental wellbeing measured using the Warwick-Edinburgh Mental Well-being scale (WEMWBS)
6. Back pain measured using the Roland-Morris Disability Questionnaire
7. Activity use and preference measured using questionnaires developed by the researchers
8. Staff turnover measured by the number of people leaving and number of new joiners over the study period (both in the contact centre as a whole and in the people taking part in the research)
9. Demographics (age, gender, medical conditions which may impact on sedentary behaviour)
Measured at a maximum of three occasions per site: at the end of the control period, and at 3 and 6 months after the end of the intervention in each site
