Analytic Methodology Work Group Meeting, National Health Security Preparedness Index February 2, 2015 April 8, 2015 NHSPI Program Management Office University of Kentucky

Agenda Scaling Measures Old = actual/max ; trimming at +2 S. D New = (actual – min)/(max-min) Weighting Approach Old = equal weighting of items within subdomains gives rise to large differences in implicit weighting in the overall Index New = weights based on expert panel Delphi ratings An Equal Opportunity University �

Scaling and Weighting Don’t want the measure scaling to have a differential impact on Index scores Dichotomous v. continuous Do want the weighting to be explicit and reflect underlying science

Scaling Measures New scaling [(actual – min)/(max-min)] does not exercise a differential impact on Index scores Dichotomous & continuous measures scaled similarly

Weighting • Expert panel, online Delphi approach – What gets weighted? • measures, subdomains, and/or domains? – Weighted with respect to what? • state-specific risks, all hazards, uniform planning scenarios? – Who are the experts?
