Methods of Data Collection for
SCHIP Evaluations
SCHIP Workshop presenter Linda Bilheimer, Deputy
Assistant at the Congressional Budget Office, discussed basic approaches and data sources
for evaluation of State SCHIP programs.
There are three basic methods States can use to evaluate SCHIP, and most States will
likely use some combination of all of these approaches:
- Sample Surveys. These surveys are critical tools since they provide
population-based estimates. Although the Current Population Survey (CPS) is most
widely utilized, States should use it with caution since it is not designed to provide
State-specific estimates. Standard errors are high when attempting to extrapolate
State-specific data, since each State represents only a small subset of the CPS
population.
- Administrative Databases. These databases can yield information
on effectiveness of outreach and enrollment strategies, stability of coverage,
displacement of private coverage, and effects of SCHIP on access and use of services.
- Qualitative Analyses Based on Site Visits. Visits to sites where
uninsured children and families are likely to be can yield valuable information on the
effectiveness of outreach and enrollment strategies.
In evaluating SCHIP, States will want to look at the effects of all aspects of the
program on insurance coverage. This will require assessments of all program processes from
outreach and enrollment strategies to participants' use of services.
