  • Vital Signs

    Open AccessAndrea S Gentzke, Melisa R Creamer et al.ARTICLEMMWR. Surveillance Summaries2019

    INTRODUCTION: Tobacco use is the leading cause of preventable disease and death in the United States; nearly all tobacco product use begins during youth and young adulthood. METHODS: CDC, the Food and Drug Administration, and the National Cancer Institute analyzed data from the 2011-2018 National Youth Tobacco Surveys to estimate tobacco product use among U.S. middle and high school students. Prevalence estimates of current (past 30-day) use of s…

  • Tobacco Product Use and Cessation Indicators Among Adults — United States, 2018

    Open AccessMelisa R Creamer, Teresa W Wang et al.ARTICLEMMWR. Surveillance Summaries2019

    Cigarette smoking is the leading cause of preventable disease and death in the United States (1). The prevalence of adult cigarette smoking has declined in recent years to 14.0% in 2017 (2). However, an array of new tobacco products, including e-cigarettes, has entered the U.S. market (3). To assess recent national estimates of tobacco product use among U.S. adults aged ≥18 years, CDC, the Food and Drug Administration (FDA), and the National Canc…

  • Population prevalence and predictors of self-reported exposure to court-ordered, tobacco-related corrective statements

    Kwamaine Blake, Gordon Willis et al.ARTICLETobacco Control2019

    In the first 6 months of corrective statement implementation, an estimated 40.6% of US adults reported at least one exposure to any corrective statement, and current smokers were more likely than never smokers to report exposure. Traditional media channels can be effective for tobacco-related message dissemination; however, they may fail to reach more than half of the adult population without additional targeted communication efforts

  • Improving Vignette Descriptions and Question Formats to Measure Distance Vision

    Open AccessYanfang Su, Gordon Willis et al.ARTICLECAM2017Cited by: 1References: 25

    Vignette design has been largely neglected in anchoring vignette studies. This study aimed to contribute to the science of vignette design by developing and evaluating vignettes for measuring vision in rural China. Cognitive interviews were conducted among 36 participants in a Chinese middle school. The respondents either directly evaluated vision of the vignette character (i.e., noncomparative judgment) or compared their own vision with that of …

  • Influence of English-language Proficiency on the Cognitive Processing of Survey Questions

    Open AccessHyunjoo Park, M Mandy Sha et al.ARTICLECAM2016References: 9

    When recruiting respondents for cognitive interviews testing translated survey questionnaires, researchers often recommend interviewing monolingual non-English speakers because they are the likely users of the translations. However, these individuals are hard to recruit, and there is no standard definition of monolingual. Using cognitive interview data collected from pretesting of Chinese and Korean translations of the American Community Survey L…

  • Sources of Interactional Problems in a Survey of Racial/Ethnic Discrimination

    Timothy P Johnson, S Shariff-Marco et al.ARTICLEInternational Journal of Public…2014Cited by: 2References: 4

    Cross-cultural variability in respondent processing of survey questions may bias results from multiethnic samples. We analyzed behavior codes, which identify difficulties in the interactions of respondents and interviewers, from a discrimination module contained within a field test of the 2007 California Health Interview Survey. In all, 553 (English) telephone interviews yielded 13,999 interactions involving 22 items. Multilevel logistic regressi…

  • What Do Our Respondents Think We're Asking? Using Cognitive Interviewing to Improve Medical Education Surveys

    Gordon Willis, Gordon B Willis et al.ARTICLEJournal of Graduate Medical…2013

    Consider the last time you answered a questionnaire. Did it contain questions that were vague or hard to understand? If yes, did you answer these questions anyway, unsure if your interpretation aligned with what the survey developer was thinking? By the time you finished the survey, you were probably annoyed by the unclear nature of the task you had just completed. If any of this sounds familiar, you are not alone, as these types of communication…

  • Reproducibility of physical activity recall over fifteen years

    Open AccessAshley Wilder Smith, Kathleen A Cronin et al.ARTICLEBMC Public Health2013

    PA recall from the distant past is moderately reproducible, but poor at the individual level, among young and middle aged adults

  • A comparison of alternative methods for measuring cigarette prices

    Frank J Chaloupka, John A Tauras et al.ARTICLETobacco Control2013

    The TUS-CPS can be used to construct valid measures of cigarette prices. Unlike the TBOT, the TUS-CPS captures the effect of price-reducing marketing strategies, as well as tax avoidance practices and non-traditional types of purchasing. Thus, self-reported data like TUS-CPS appear to have advantages over TBOT in estimating the 'real' price that smokers face

  • Do Additional Recontacts to Increase Response Rate Improve Physician Survey Data Quality

    Gordon Willis, Gordon B Willis et al.ARTICLEMedical Care2013References: 8

    BACKGROUND: Although response rates for physician surveys have been decreasing, it is not clear whether this trend is associated with an increase in survey nonresponse bias. One means for assessing potential bias is to conduct a level-of-effort analysis that compares data estimates for respondents interviewed during the first recruitment contact to respondents interviewed at later recontact cycles. METHODS: We compared early and later responders …

  • The meaning of ‘fruits’ and ‘vegetables’

    Open AccessFrances E Thompson, Gordon Willis et al.ARTICLEPublic Health Nutrition2011

    Objective Fruit and vegetable consumption is a focus of research and nutrition education; yet, there is no universal agreement on the meaning of ‘fruits’ and ‘vegetables’. Our objective was to describe survey respondent perceptions about a set of foods with regard to whether the food is a fruit, vegetable or something else. Design Three cross-sectional studies. Setting Two small studies involving cognitive interviewing sessions; and one large sel…

  • Comparing Cognitive Interviewing and Psychometric Methods to Evaluate a Racial/Ethnic Discrimination Scale

    Open AccessBryce B Reeve, Gordon Willis et al.ARTICLECAM2011Cited by: 27References: 22

    Proponents of survey evaluation have long advocated the integration of qualitative and quantitative methodologies, but this recommendation has rarely been practiced. The authors used both methods to evaluate the "Everyday Discrimination" scale (EDS), which measures frequency of various types of discrimination, in a multiethnic population. Cognitive testing included 30 participants of various race/ethnic backgrounds and identified items that were …

  • Measuring Everyday Racial/Ethnic Discrimination in Health Surveys

    Open AccessSalma Shariff-Marco, Nancy Breen et al.ARTICLEDu Bois Review Social Science…2011Cited by: 66References: 49

    While it is clear that self-reported racial/ethnic discrimination is related to illness, there are challenges in measuring self-reported discrimination or unfair treatment. In the present study, we evaluate the psychometric properties of a self-reported instrument across racial/ethnic groups in a population-based sample, and we test and interpret findings from applying two different widely-used approaches to asking about discrimination and unfair…

  • Cognitive testing of physical activity and acculturation questions in recent and long-term Latino immigrants

    Open AccessDavid Berrigan, Barbara H Forsyth et al.ARTICLEBMC Public Health2010

    Standardized survey questions related to acculturation and physical activity present somewhat different cognitive challenges. For PA related questions, problems with such questions were similar regardless of subject residence time or language preference. For acculturation related questions, residence time/language or education level influenced responses to such questions. These observations should help in the interpretation of survey results for …

    This article reports research on procedures for translating a survey questionnaire on tobacco use from English into Mandarin Chinese, Cantonese Chinese, Korean, and Vietnamese. The goal is to offer practical guidelines for researchers involved in translating questionnaires. The authors operationalize a five-step process for translation and evaluation based on the frameworks presented in Harkness, Van de Vijver, and Mohler (2003) and the U.S. Cens…

  • Cognitive Interviewing as a Tool for Improving the Informed Consent Process

    Open AccessGordon WillisARTICLEJournal of Empirical Research on…2006Cited by: 5References: 3

    Consent materials often contain complex information, legalese, and other features that render them difficult to comprehend in such a way that consent is truly informed. I propose that researchers adapt cognitive interviewing, normally used for the pretesting of survey questionnaires, to evaluate the understandability of consent materials and the way which subjects use this information to make decisions regarding participation. Cognitive interview…

    David Nelson, David E Nelson et al.ARTICLEJournal of Health Communication2004

    Little is known about access, sources, and trust of cancer-related information, or factors that facilitate or hinder communication on a population-wide basis. Through a careful developmental process involving extensive input from many individuals and organizations, the National Cancer Institute (NCI) developed the Health Information National Trends Survey (HINTS) to help fill this gap. This nationally representative telephone survey of 6,369 pers…
