Questionnaire designers use readability measures to ensure that questions can be understood by the target population. The most common measure is the Flesch-Kincaid Grade level, but other formulas exist. This article compares six different readability measures across 150 questions in a self-administered questionnaire, finding notable variation in calculated readability across measures. Some question formats, including those that are part of a battery, require important decisions that have large effects on the estimated readability of survey items. Other question evaluation tools, such as the Question Understanding Aid (QUAID) and the Survey Quality Predictor (SQP), may identify similar problems in questions, making readability measures less useful. We find little overlap between QUAID, SQP, and the readability measures, and little differentiation in the tools’ prediction of item nonresponse rates. Questionnaire designers are encouraged to use multiple question evaluation tools and develop readability measures specifically for survey questions.

In this article, we address the issue of reliability of quantitative data on multilingualism of the past obtained as recall data. More specifically, we investigate whether the interviewees’ assessments of the language repertoires of their late relatives (indirect data) provide results that are quantitatively similar to those obtained from the people of the same age range themselves (direct data). The empirical data we use come from an ongoing field study of traditional multilingualism in Daghestan (Russia). We trained machine learning models to see whether they can detect differences in indirect and direct data. We conclude that our indirect quantitative data on L2 other than Russian are essentially similar to direct data, while there may be a small but systematic underestimation when reporting others’ knowledge of Russian.

Attention checks detect inattentiveness by instructing respondents to perform a specific task. However, while respondents may correctly process the task, they may choose to not comply with the instructions. We investigated the issue of noncompliance in attention checks in two web surveys. In Study 1, we measured respondents’ attitudes toward attention checks and their self-reported compliance. In Study 2, we experimentally varied the reasons given to respondents for conducting the attention check. Our results showed that while most respondents understand why attention checks are conducted, a nonnegligible proportion of respondents evaluated them as controlling or annoying. Most respondents passed the attention check; however, among those who failed the test, 61% seem to have failed the task deliberately. These findings reinforce that noncompliance is a serious concern with attention check instruments. The results of our experiment showed that more respondents passed the attention check if a comprehensible reason was given.

Although list-style open-ended questions generally help us gain deeper insights into respondents’ thoughts, opinions, and behaviors, the quality of responses is often compromised. We tested a dynamic and a follow-up design to motivate respondents to give higher quality responses than with a static design, but without overburdening them. Our results showed that a follow-up design achieved longer responses with more themes and theme areas than a static design. In contrast, the dynamic design produced the shortest answers with the fewest themes and theme areas. No differences in item nonresponse and only minor differences in additional response burden were found among the three list-style designs. Our study shows that design features and timing are crucial to clarify the desired response format and motivate respondents to give high-quality answers to list-style open-ended questions.

Frequency of behaviors or amounts of variables of interest are essential topics in many surveys. The use of heuristics might cause rounded answers, resulting in the increased occurrence of end-digits (called heaping or digit-preference). For web surveys (or CASI), we propose using a conditional prompt as input validation if digits indicating heaping are entered. We report an experiment, where respondents in an online access panel (n = 2,590) were randomly assigned to one of three groups: (1) no input validation; (2) conditional input validation if rounding was presumed; and (3) input validation every time a numerical value was entered. Conditional input validation reduces heaping for variables with high proportions of heaped values. Unconditional input validation seems to be less effective.

To date, research on elite interviews has primarily focused on political or business settings in European and Anglo-American contexts. In this study, we examine the procedures involved in conducting elite interviews in academic settings, drawing on fieldwork with 53 senior scholars at 10 universities across five regions of northern China. We provide a detailed, critically reflective account of strategies to gain access, develop trust, and manage the power imbalance. Our account reveals the importance of the researcher’s professional identity in gaining participants’ trust and determining adequate forms of reciprocity.

Despite the widespread use of examples in survey questions, very few studies have examined their impact on survey responses, and the evidence is mainly based on data collected in the United States using questionnaires in English. This study builds on previous research by examining the effects of providing examples using data from a cross-national probability-based web panel implemented in Estonia (n = 730), Great Britain (n = 685), and Slovenia (n = 529) during Round 8 of the European Social Survey (2017/18). Respondents were randomly assigned a survey question measuring confidence in social media using Facebook and Twitter as examples, or another condition in which no examples were offered. The results show that confidence in social media was significantly lower in the example condition, although the effect size was small. Confidence in social media varied across countries, and the effect of providing examples was heterogeneous across countries and education levels. The implications of these findings are discussed.

Place-based initiatives often use resident surveys to inform and evaluate interventions. Sampling based on well-defined sampling frames is important but challenging for initiatives that target subpopulations. Databases that enumerate total population counts can produce overinclusive sampling frames, resulting in costly outreach to ineligible participants. Quantifying eligibility before sampling using machine learning algorithms can improve efficiency and reduce costs. We developed a model to improve sampling for the West Philly Promise Neighborhood’s biennial population-representative survey of households with children within a geographic footprint. This study proposes a method to estimate probability of study eligibility by building a well-calibrated predictive model using existing administrative data sources. Six machine-learning models were evaluated; logistic regression provided the best balance of accuracy and understandable probabilities. This approach can be a blueprint for other population-based studies whose sampling frames cannot be well defined using traditional sources.

Telephone surveys face more and more criticism because of decreasing coverage and increasing costs, and the risk of producing socially desirable answers. Consequently, survey administrators consider switching their surveys to the web mode, although the web mode is more susceptible to item nonresponse. Still, we do not know whether this is true for all question types. In this article, we analyze to what extent item nonresponse depends on question characteristics such as their form or difficulty in the telephone and the web mode. We use data from an experiment in which individuals randomly sampled from a population register are experimentally assigned to these two modes. Distinguishing effects on the frequency of don’t know responses, item refusals, and mid-scale responding, we find more don’t know responses and item refusals for the web mode generally, but no differences for mid-scale responding. However, this relationship depends on the characteristics of the question.

We review ethnographic methods that allow researchers to assess distress in a culturally sensitive manner. We begin with an overview of standardized biomedical and psychological approaches to assessing distress cross-culturally. We then focus on literature describing the development of reliable and valid culturally sensitive assessment tools that can serve as complements or alternatives to biomedical categories and diagnostic frameworks. The methods we describe are useful in identifying forms of suffering—expressed in culturally salient idioms of distress—that might be misidentified by biomedical classifications. We highlight the utility of a cognitive anthropological theoretical approach for developing measures that attend to local cultural categories of knowledge and experience. Attending to cultural insider perspectives is necessary because expressions of distress, thresholds of tolerance for distress, expectations about stress inherent in life, conceptions of the good life, symptom expression, and modes of help-seeking vary across cultures.
