Abstract:
|
Converted Refusals have been hypothesized or proposed to decrease nonresponse bias of survey estimates. However, few studies have tested this hypothesis due to the lack of administrative data on these individuals. Beginning in 1999, the start of the continuous National Health and Nutrition Examination Survey, administrative data has been used to identify converted refusals. Focusing on adults 20 years and older we will address the issue of non-response bias by measuring the impact on converted refusals upon survey estimates. New sample weights will be constructed with the converted refusals treated as non-respondents. Based on these sample weights, the percent of adults with selected health characteristics will be estimated. These estimates will then be compared to corresponding estimates based on original sample weights where the converted refusals were treated as survey participants
