NASS Review of Revision to OMB 0584- NEW

Study of WIC Food Package Costs and Cost Containment

September, 2016

By Chunlin Dong, Mathematical Statistician

• The research purpose and objectives of this study are clearly explained in “Supporting Statement Part A.pdf”.

• Using the same data collection mode – computer assisted telephone interview - for both the current WIC Participant Survey and former WIC Participant Survey helps to ensure consistent data.

• The Sampling Frame and Sampling Design are appropriate.

  • A procedure is outlined to ensure the quality of the sampling frame: addressing possible duplication and removing records that do not qualify.

  • Explicit stratification by state, urban/rural category and by infant presence and implicit stratification by family participants.

  • The sample size will be increased to anticipate non-response.

  • Sampling weights will be adjusted to account for unit nonresponse.

• It is appropriate to collect data at several different time points in order to conduct an in-depth analysis in health outcomes and the trends in redemption.

SUGGESTIONS

1. Consider changing the column names in Table A.12.1 - Supporting Statement Part A.pdf - to that highlighted with a yellow background.
