The Effectiveness of the Item Count Technique in Eliciting Valid Answers to Sensitive Questions. An Evaluation in the Context of Self-Reported DelinquencyFelix Wolter & Bastian Laier
Surveys often contain sensitive questions, that is, questions about private, illegal, or socially undesirable behavior. When asked directly in standard survey modes, respondents tend to underreport these behaviors, yielding biased results. One method that promises more valid estimates than direct questioning (DQ) is the item count technique (ICT). In this paper, methodological benefits and disadvantages of the ICT, as compared to DQ, are empirically evaluated with regard to questions on self-reported delinquency. We present findings...

Panel surveys suffer from attrition. Most panel studies use propensity models or weighting class approaches to correct for non-random dropout. These models draw on variables measured in a previous wave or from paradata of the study. While it is plausible that they affect contactability and cooperativeness, panel studies usually cannot assess the impact of events between waves on attrition. The amount of change in the population could be seriously underestimated if such events had an...
Survey organizations rely on interviewers to make informed and efficient decisions about their efforts in the field, including which housing units they approach to knock on doors, make appointments, and obtain interviews. This paper presents initial findings from a feasibility test on a face to face survey, the US National Survey of Family Growth, in which the interviewers were equipped with GPS-enabled smartphones. This test included an experiment to determine if the use of the...
Positive, negative, and bipolar questions: The effect of question polarity on ratings of text readabilityNaomi Kamoen, Bregje Holleman, Huub Van Den Bergh & Ted Sanders
For decades, survey researchers have known that respondents give different answers to attitude questions worded positively (X is good. Agree-Disagree), negatively (X is bad. Agree-Disagree) or on a bipolar scale (X is bad-good). This makes survey answers hard to interpret, especially since findings on exactly how the answers are affected are conflicting. In the current paper, we present twelve studies in which the effect of question polarity was measured for a set of thirteen contrastive...
This paper reports the design and outcomes of a pilot study for the UK Household Longitudinal Study (UKHLS), Understanding Society, to develop and test the feasibility of collection of biomarkers by trained non-clinical interviewers. Feasibility tests performance of procedures, that they are technically satisfactory and reasonable in relation to alternatives. The dimensions reported are recruitment and training of interviewers, completeness, acceptability and time required for data collection, and quality of the biological samples. Some comparisons...
Worry about Crime among European Citizens: Model-Assisted Measurement using European Social Survey DataJonathan Jackson & Jouni Kuha
This paper examines new measures of fear of crime fielded in the European Social Survey. We use an analytical approach that combines statistical latent class modelling with pragmatic choices for the final classification of the responses into a six-category measure. We undertake an informal examination of the latent class solution in individual countries, and we show that frequency and impact indicators are reliable cross-national indicators (with configural or construct validity) of the experience of negative...
