Table 5 Second stage filter analysis

From: Cost-effectiveness of active transport for primary school children - Walking School Bus program

Level of evidence Equity Acceptability Feasibility Sustainability Side-effects
May be effective:
No Level I or II evidence
Modelling based on Level IV evidence
Further effectiveness data sought but does not appear to support intervention's effectiveness.
Moderate equity concerns:
Less access for children in rural and remote areas
Less acceptable to older children in primary schools
Requires a big time commitment from the school community, which may not be acceptable to all schools
Likely issues:
Variations in service delivery model between states make national implementation complex and question of appropriate auspicing body difficult.
Substantial fixed costs for set-up and ongoing maintenance
Likely issues:
Program requires ongoing funding & support, which may impact on sustainability.
Less traffic, pollution, safer around schools.
Facilitates social networks.
Increases awareness of local neighbourhoods
Enhances pedestrian skills.
May be positive impacts on family travel behaviour
Potential to decrease the number of parents walking
Decision points
: Weak evidence of effectiveness
Moderate issue Not a major issue Some significant concerns Issue which needs to be addressed Significant wider positive benefits
Policy considerations:
The WSB intervention is not cost-effective in terms of its effect on obesity in children under current uptake results. Action to improve uptake is worthy of consideration. Further, the intervention was not designed as an obesity prevention initiative, but as a program to produce change in the travel behaviour of students and to promote a safer traffic environment around schools. Lack of data on the incremental change in the numbers taking up active transport as a consequence of the intervention is a key limitation.
