Methodology and Data Collection
Data Analysis
Reporting and Dissemination
Identify your intervention stage:
Planning –
You and your partners are in the process of designing your intervention goals, objectives, activities, partners’ roles and responsibilities, and resources needed to carry out the intervention.
Implementation –
You and your partners are engaged in intervention delivery.
Enforcement/maintenance –
You and your partners are trying to sustain the intervention beyond the original timeline for intervention delivery.
Depending on your intervention stage, your evaluation plan may address one or more of the following four evaluation types:
1. Formative evaluation
Planning stage → Formative evaluation Formative evaluation is frequently referred to as “community assessment”, or the examination of a community’s assets, needs, current resources, strengths, and challenges. Asset mapping identifies the changes that need to occur in the community to improve health. Needs assessment documents the resources and supports that already exist in your community. A comprehensive formative evaluation can address:- Decisions about where to focus resources and interventions in order to maximally benefit the community;
- Understanding of the relationships between pedestrian safety interventions, pedestrian and driver behaviors, and health and related outcomes;
- Characteristics of the partnership and the population prior to intervention to identify factors for tracking or monitoring change; and
- Contextual factors that can influence the intervention or evaluation (e.g., concentrated poverty or areas with a small local tax base, rural communities or areas with a small population density).
2. Process evaluation
Implementation stage → Process evaluation
Process evaluation helps you and your partners determine how well the intervention is working.
Factors such as feasibility, cost, reach, and unanticipated barriers can positively or negatively affect implementation fidelity and the population’s satisfaction with the intervention.
Process evaluation involves an assessment of how well intervention activities are carried out (e.g., policies, media, partner or community meetings), including evaluation of both the partnership and the pedestrian safety intervention.
3. Impact evaluation
If intervention implementation is partially or fully complete, impact evaluation can demonstrate how and to what degree intervention objectives have been attained.
4. Outcome evaluation
If intervention implementation is fully complete, outcome evaluation demonstrates how and to what degree intervention goals have been attained.
Multi-component and complex pedestrian safety interventions
You and your evaluation partners may have different policy, practice, environmental, programmatic, or promotional components in various intervention stages, thus multiple types of evaluation may be occurring simultaneously.
“Downstream” and “Upstream” intervention components
You and your evaluation partners are likely to evaluate your policy, practice, environmental, programmatic, or promotional components or your “downstream” intervention strategies.
