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 not available for this objective. 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) took into consideration the stakeholder coalitions located throughout the country that have contributed to cancer control plans to help lower the number of people affected by cancer. Most cancer control plans include priorities related to skin cancer prevention. Therefore, the SMEs viewed the target as ambitious yet achievable.


Methodology notes

Data include adolescents who reported a sunburn one or more times in the past 12 months.


Comparable HP2020 objective
Retained, which includes core objectives that are continuing from Healthy People 2020 with no change in measurement.
Revision History
