The Workplace Sitting Intervention
A local council employs 240 office staff across two sites. A survey finds staff sit for an average of 9.5 hours per day, with 62% reporting neck or lower back discomfort in the past month. Only 21% accumulate 150 minutes of moderate activity per week. The council has a $40,000 budget and 12 months. Management proposes standing desks for all 240 staff ($36,000). Staff representatives propose a multi-component program: 10-minute walking meetings, two 15-minute activity breaks per week, a stairwell challenge, and manager training ($22,000), with the remainder for evaluation. One site has no showers and limited secure bike storage.
1. Compare the two proposals using a health promotion planning framework, and recommend an approach.

Comparison using a planning framework (assess, plan, implement, evaluate):
| Criterion | Standing desks only | Multi-component program |
|---|---|---|
| Evidence base | Modest effect on sitting time; little effect on total activity | Consistent evidence that multi-component workplace programs reduce sitting and increase activity |
| Reach | All 240 staff, but passive use | Reaches motivated staff; walking meetings and breaks can reach more if manager-supported |
| Addresses barriers | Does not address time, culture, or facilities | Addresses culture via manager training; does not address showers or bike storage |
| Sustainability | One-off capital cost; no ongoing support | Requires ongoing scheduling and leadership commitment |
| Evaluation | Easy to measure usage | Built-in evaluation budget |
Recommendation: Adopt the multi-component program as the core, because it targets the organisational culture and sedentary behaviour that the 9.5-hour sitting average reflects, and because it includes evaluation. Use part of the standing desk budget for a smaller number of shared height-adjustable desks at hot-desk stations, and allocate funds to secure bike storage, since the facility gap is a concrete barrier to the 21% activity figure.
Caveat: Without manager training being mandatory and breaks being scheduled rather than optional, uptake will likely be low and unequal.
2. Identify the outcome and process indicators the council should use to evaluate the program after 12 months.
Read the worked answer
Process indicators (was it delivered as planned?):
- Number and proportion of staff attending at least one activity break per week, and number of walking meetings held.
- Proportion of managers who completed training, and staff-reported managerial support.
- Number of stairwell challenge participants and desks installed.
- Uptake of bike storage and shower access if provided.
Outcome indicators (did anything change?):
- Change in self-reported daily sitting time (target: reduce from 9.5 hours).
- Change in proportion meeting 150 minutes of moderate activity per week (baseline 21%).
- Change in prevalence of neck and lower back discomfort in the past month (baseline 62%).
- Optional objective measures such as pedometer steps or sit-stand time from a subsample.
Design notes: Use a pre-post survey with the same questions and a comparison group at a third site if available. Report participation by site, since one site lacks showers and storage, and stratify by job role to check whether benefits are concentrated among already-active staff. Set targets in advance and report confidence intervals rather than only averages.
