Earnings nonresponse in household surveys is widespread, yet there is limited evidence on whether and how nonresponse bias affects measured earnings. This paper examines the patterns and consequences of nonresponse using internal Current Population Survey individual records linked to administrative Social Security Administrative data on earnings for calendar years 2005-2010. Our findings confir...

The present study examined pretreatment and process predictors of individual nonresponse to psychological group treatment of binge eating disorder (BED). In a randomized trial, 162 overweight patients with BED were treated with either group cognitive-behavioral therapy or group interpersonal psychotherapy. Treatment nonresponse, which was defined as nonabstinence from binge eating, was assessed...

BACKGROUND Low response and reporting errors are major concerns for survey epidemiologists. However, while nonresponse is commonly investigated, the effects of misclassification are often ignored, possibly because they are hard to quantify. We investigate both sources of bias in a recent study of the effects of deployment to the 2003 Iraq war on the health of UK military personnel, and attempt ...

Methods for estimating nonresponse bias are reviewed and several methods are tried on the 1980 GSS. The results indicate that various estimating procedures are inappropriate and that even the more promising techniques can provide faulty estimates of nonresponse bias. By its nature, nonresponse bias is very difficult to assess accurately and no simple, certain method exists. Tom W. Smith is Seni...

In sample surveys, we always deal with two types of errors: Sampling error and non-sampling error. One of the most common non-sampling errors is nonresponse. This error happens when some sample units are not observed or viewed but they do not answer some of the questions. The complete prevention of this error is not possible, but it can be significantly reduced. The non-response causes bias and ...

The Current Population Survey (CPS) adjusts the sampling weights for nonresponse to match population controls based on cells which combine similar primary sampling units (PSU) based on size and urbanicity. The adjustment method assumes that the nonresponse is random within the adjustment cells. This adjustment increases weights for responding units in PSUs with higher nonresponse. The present s...

BACKGROUND Informal caregiving is becoming more relevant with current trends such as population ageing. However, little is known about nonconsent and nonresponse bias in caregiving research. We investigated nonconsent and nonresponse bias in a sample of informal caregivers who participated in the LifeLines Cohort Study, and were invited for participation in an additional caregiving study. MET...

Is Earnings Nonresponse Ignorable? Earnings nonresponse in the Current Population Survey is roughly 30% in the monthly surveys and 20% in the annual March survey. Even if nonresponse is random, severe bias attaches to wage equation coefficient estimates on attributes not matched in the earnings imputation hot deck. If nonresponse is ignorable, unbiased estimates can be achieved by omitting impu...

A large-scale mixed-mode experiment linked to the Dutch Crime Victimization Survey was conducted in 2011. The experiment consisted of two waves; one wave with random assignment to one of the modes web, paper, telephone and face-to-face, and one follow-up wave to the full sample with interviewer modes only. The objective of the experiment is to estimate total mode effects and more specifically t...
