Wireless substitution: state-level estimates from the National Health Interview Survey, 2010-2011.

Objectives: This report updates subnational estimates of the percentage of adults and children living in households without a landline telephone but with at least one wireless telephone (i.e., wireless-only households).

Comparing errors in Medicaid reporting across surveys: evidence to date.

Objective: To synthesize evidence on the accuracy of Medicaid reporting across state and federal surveys.

Data Sources: All available validation studies.

Study Design: Compare results from existing research to understand variation in reporting across surveys.

Deployment of a mixed-mode data collection strategy does not reduce nonresponse bias in a general population health survey.

Objective: To assess nonresponse bias in a mixed-mode general population health survey.

Data Sources: Secondary analysis of linked survey sample frame and administrative data, including demographic and health-related information.

Study Design: The survey was administered by mail with telephone follow-up to nonrespondents after two mailings.

Wireless substitution: state-level estimates from the National Health Interview Survey, January 2007-June 2010.

Objectives: This report presents state-level estimates of the percentage of adults and children living in households that did not have a landline telephone but did have at least one wireless telephone. National estimates for the 12-month time period from July 2009 through June 2010 indicate that 23.9% of adults and 27.

Who doesn't authorize the linking of survey and administrative health data? A general population-based investigation.

Purpose: To determine the extent of authorization bias in a study linking survey and medical record data in a general population-based investigation.

Methods: Authorization status (authorized data linkage vs. not) was ascertained through a sequential mixed mode mail and telephone survey conducted in Olmsted County, MN.

Health Insurance Portability and Accountability Act (HIPAA) authorization and survey nonresponse bias.

Objectives: To extend earlier work (Beebe et al, Med Care. 2007;45:959-965) that demonstrated Health Insurance Portability and Accountability Act authorization form (HAF) introduced potential nonresponse bias (toward healthier respondents).

Research Design: The sample frame from the earlier experiment was linked to administrative medical record data, enabling the comparison of background and clinical characteristics of each set of respondents (HAF and No HAF) to the sample frame.

Twenty years of coverage: an enhanced current population survey-1989-2008.

Objective: To create a consistent time series to understand coverage trends by harmonizing 20 years of insurance coverage estimates from the Current Population Survey (CPS) that are an available public resource.

Data Source: 1990-2009 CPS Annual Social and Economic Supplement data.

Study Design: CPS data are enhanced to account for methodological and conceptual changes in health insurance measurement and population control totals.

Wireless substitution: state-level estimates from the National Health Interview Survey, January-December 2007.

Objectives: This report presents state-level estimates of the percentage of households that do not have a landline telephone, but do have at least one wireless telephone. These wireless-only households made up 14.7% of U.

Survey-related experiential and attitudinal correlates of future health survey participation: results of a statewide survey.

Objective: To determine the survey-related experiential and attitudinal correlates of future health-related survey participation.

Participants And Methods: From July 21, 2005, through October 25, 2005, we conducted a mixed-mode mail and telephone survey of 1636 noninstitutionalized Minnesota residents aged 18 years or older. The overall response rate was 49%.

Four decades of population health data: the integrated health interview series as an epidemiologic resource.

The National Health Interview Survey (NHIS) is a primary source of information on the changing health of the US population over the past 4 decades. The full potential of NHIS data for analyzing long-term change, however, has rarely been exploited. Time series analysis is complicated by several factors: large numbers of data files and voluminous documentation; complexity of file structures; and changing sample designs, questionnaires, and variable-coding schemes.

Local access to care programs (LACPs): new developments in the access to care for the uninsured.

Context: New, locally based health care access programs are emerging in response to the growing number of uninsured, providing an alternative to health insurance and traditional safety net providers. Although these programs have been largely overlooked in health services research and health policy, they are becoming an important local supplement to the historically overburdened safety net.

Methods: This article is based on a literature review, Internet search, and key actor interviews to document programs in the United States, using a typology to classify the programs and document key characteristics.

The effects of survey mode and asking about future intentions on self-reports of colorectal cancer screening.

Colorectal cancer (CRC) screening rates are often ascertained via self-reports but can be subject to overreporting bias. Asking about intention to get screened before asking about past screening may minimize overreporting of cancer screening. In a statewide survey conducted from July through October of 2005, we embedded an experiment that tested the effect of question ordering (asking about future intention to get screened before or after asking about past screening; "future first" and "future second," respectively), crossed with survey mode (mail versus telephone), on CRC screening rates.

The impact of smoking-cessation intervention by multiple health professionals.

Background: Smokers have contact with many different types of health professionals. The impact of tobacco intervention by multiple types of heath professionals is not known.

Methods And Materials: As part of the 2003 Minnesota Adult Tobacco Survey, smokers (n=1723) reported on tobacco treatment by medical doctors, nurses, dentists, pharmacists, or other health professionals.

Mixing web and mail methods in a survey of physicians.

Objective: To assess the effects of two different mixed-mode (mail and web survey) combinations on response rates, response times, and nonresponse bias in a sample of primary care and specialty internal medicine physicians.

Data Sources/study Setting: Primary data were collected from 500 physicians with an appointment in the Mayo Clinic Department of Medicine (DOM) between February and March 2005.

Study Design: Physicians were randomly assigned to receive either an initial mailed survey evaluating the Electronic Medical Record (EMR) with a web survey follow-up to nonrespondents or its converse-an initial web survey followed by a mailed survey to nonrespondents.

Comparison of two within-household selection methods in a telephone survey of substance abuse and dependence.

Purpose: Random-digit dial telephone surveys often rely on the random selection of one respondent within the household. We compared a new method of within-household selection to a standard "next birthday" approach on selected survey process measures, respondent characteristics, and substantive results.

Methods: From October 2004 through June 2005, we conducted a survey of adults in Minnesota to obtain information about substance use and need for treatment.

Mail surveys resulted in more reports of substance use than telephone surveys.

Objective: To determine to what extent the substance-use information obtained in surveys is affected by method of data collection.

Study Design And Setting: Questions on the use of alcohol and drugs were administered to samples of Minnesota adults assigned to one of two conditions to test the effect of mode of administration (mail and telephone); 816 persons completed the survey, roughly one half by mail and one half by telephone.

Results: Those interviewed by telephone revealed more heavy use of alcohol, but the mail sample includes disproportionate numbers of respondents from demographic groups that exhibit less use.

Increasing response rates in a survey of Medicaid enrollees: the effect of a prepaid monetary incentive and mixed modes (mail and telephone).

Objectives: We sought to evaluate the effect of pairing a mixed-mode mail and telephone methodology with a prepaid US 2.00 dollars cash incentive on response rates in a survey of Medicaid enrollees stratified by race and ethnicity.

Research Design: Sampling was conducted in 2 stages.
