Take A Stand for Workplace Health: A Sit-stand Workstation Project Evaluation

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to examine the contribution of sit-stand workstations to total daily physical activity in a multi-component office-based 12 month intervention.

Detailed Description
-----------------
This study adopts a randomised control trial design and is mixed methods (qualitative and quantitative). The outcome data from the trial is quantitative. Alongside this a qualitative process evaluation will be conducted to inform the intervention, explain trial results and understand the intervention implementation and context (Cathain et al. 2014). Two worksites will participate in this study, in line with COCHRANE recommendations for randomised control trials.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: multi-component intervention<br>Sit-stand workstation provision The multi-component intervention will align with the World Health Authority's promotion of a healthy workplace model, which emphasises that best-practice workplace health interventions should involve an integrated approach involving organisation and individual level approaches to behaviour change (WHO, 2010). Thus, participants will receive a sit-stand workstation with additional support to use the sit-stand workstation. | Behavioral: Sit-stand workstation provision<br>* The research compares the effects of a sit-stand workstation only and a multi-component sit-stand workstation intervention including individual and organisation-level approaches, with usual office-based working practice (no sit-stand workstation) over 12 months.<br>* Other names: Ergotron: workfit-A, workfit-D;|
| Experimental: Sit-stand workstation only<br>Sit-stand workstation provision Participants in this arm will receive a sit-stand workstation. They will not receive any support to use the sit-stand workstation, except some health and safety advice upon installation. | Behavioral: Sit-stand workstation provision<br>* The research compares the effects of a sit-stand workstation only and a multi-component sit-stand workstation intervention including individual and organisation-level approaches, with usual office-based working practice (no sit-stand workstation) over 12 months.<br>* Other names: Ergotron: workfit-A, workfit-D;|
| No Intervention: Usual practice (seated workstation)<br>This arm is the control group. They will continue to use their usual seated workstation for the duration of the study. | |

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Physical Activity | ActivPAL: Sitting and standing will be measured objectively using the ActivPAL device. The ActivPAL provides reliable measures of total sitting time and standing time, and number of sit-to-stand transitions per hour (Lyden et al. 2012). ActiGraph (GT3X+): Physical activity intensity and duration will be measured objectively using the ActiGraph activity monitor.The GT3X reliably classifies physical activity intensity in free-living environments (Ozemek et al. 2014). Activity diaries: These dairies will be used to assess the type and context of physical activity behaviour. A text reminder will be sent to all participants once daily for the duration of the data collection period. Text message models have shown some success in increasing compliance to research (Armstrong et al. 2009). | Measured 5 times over 13 months, for seven days each time. Time points = baseline, 1-2weeks, 3 months, 6 months and 12 months |
