Target-setting method

Percentage point improvement

Target-setting method details
Percentage point improvement from the baseline using Cohen's h effect size of 0.10.
Target-setting method justification
Trend data were evaluated for this objective but it was not possible to project a target because the trend was moving away from the desired direction and the slope of the line was not statistically significant. A percentage point improvement was calculated using Cohen's h effect size of 0.1. This method was used because the Healthy People 2030 Workgroup Subject Matter Experts (SMEs) expected the overall percentage may be difficult to change. Although this target is ambitious, the SMEs believed that progress may be made through multicomponent interventions, especially for medically underserved women.


Comparable HP2020 objective
Retained, which includes core objectives that are continuing from HP2020 with no change in measurement.



Effect size h=0.1 was chosen to correspond with 10% improvement from a baseline of 50%.
