Steps in using the three dimensional Haddon matrix
| Step | Activity |
|---|---|
| 1 | Use community needs assessment data to determine the problem in need of intervention |
| 2 | Define dimension #1 (columns) of matrix as the targets of change (host, agent/vehicle or vector, physical environment, social environment) |
| 3 | Define dimension #2 (rows) of matrix by delineating the precise event and phases of change (pre-event, event, post-event) |
| 4 | Define dimension #3 (depth) of matrix by delineating value criteria, defining each in clear terms |
| 5 | Determine weights to be applied to each value listed in dimension #3 |
| 6 | Brainstorm potential interventions and fill in cells formed by columns and rows |
| 7 | Organize and/or collect data to permit assessment of each criterion for each intervention under consideration |
| 8 | Assess each intervention according to its attributes relative to each value criterion |
| 9 | Conduct overall assessment using weights for each value criterion across the set of interventions and criteria |
| 10 | Make decisions about best options |
| 11 | Explain decisions based on criteria applied and assessment of each intervention option according to the criteria |
| 12 | Document the assessment process to assist in future reanalyses |
