Evaluation of Adjustments for Nonresponse Bias Applied to Provider Nonresponse in the National Immunization Survey
نویسندگان
چکیده
Among the threats to validity of conclusions from a health survey is the bias who can result from differences between people who respond to the survey and people that do not respond. When respondents and nonrespondents have very different characteristics and the proportion of nonrespondents is at least moderately large, unadjusted survey estimates are often severely biased. Thus, it is important to evaluate the effect of nonresponse bias on the survey estimates.

OBJECTIVES The National Immunization Survey (NIS) uses two phases of data collection to obtain vaccination information from a sample of young children: a random-digit-dialing (RDD) survey for identifying households with children 19-35 months of age, followed by a mail survey for obtaining provider-reported vaccination histories about these children. Provider-reported vaccination histories are u...
متن کاملNonresponse prediction in an establishment survey using combination of statistical learning methods
Nonrespose is a source of error in the survey results and national statistical organizations are always looking for ways to control and reduce it. Predicting nonrespons sampling units in the survey before conducting the survey is one of the solutions that can help a lot in reducing and treating the survey nonresponse. Recent advances in technology and the facilitation of complex calculations...
متن کاملUsing Interviewer Observations To Improve Nonresponse Adjustments: NES 2004
Variables used in nonresponse adjustments are sometimes associated with the response outcome and sometimes with survey variables. Both associations are paramount to the reduction of nonresponse bias in survey estimates. We demonstrate that it is only when both are present that adjustments change the point estimate of the mean from the unadjusted mean. We also set out to test whether the relativ...
متن کاملStatistical Issues in a Record Check Study of Childhood Immunization
The National Immunization Provider Record Check Study is used to assess the quality of household reporting of vaccination levels for children aged 19 to 35 months. Provider nonresponse is handled by a statistical adjustment and estimates of reporting quality are produced. The findings show that both response bias and variance should be considered in this evaluation.

National Health Interview Survey (NHIS) survey weights account for complex survey design, nonresponse, and post-stratification. The National Center for Health Statistics (NCHS) can link Medicare data to NHIS respondents. A self-selected subset of NHIS participants are not “eligible” for linkage to Medicare since they refused to provide a social security number (SSN), a Health Insurance Claim (H...
