So far, modeling approaches for not-reached items have considered one single underlying process. However, missing values at the end of a test can occur for a variety of reasons. On the one hand, examinees may not reach the end of a test due to time limits and lack of working speed. On the other hand, examinees may not attempt all items and quit…

Randomized response techniques (RRTs) are applied to reduce response biases in self-report surveys on sensitive research questions (e.g., on socially undesirable characteristics). However, there is evidence that they cannot completely eliminate self-protecting response strategies. To address this problem, there are RRTs specifically designed to…

Response style, one common aberrancy in non-cognitive assessments in psychological fields, is problematic in terms of inaccurate estimation of item and person parameters, which leads to serious reliability, validity, and fairness issues (Baumgartner & Steenkamp, 2001; Bolt & Johnson, 2009; Bolt & Newton, 2011). Response style refers to…

This study explores the acquiescent response style (ARS) among respondents in the Czech Republic. To analyse ARS, confirmatory factor analysis (CFA) was employed and the response style (RS) was modelled as a latent variable. The RS factor in the CFA model must be validated by its relationship to education and age, i.e. proxies of cognitive…

The responses of non-effortful test-takers may have serious consequences as non-effortful responses can impair model calibration and latent trait inferences. This article introduces a mixture model, using both response accuracy and response time information, to help differentiating non-effortful and effortful individuals, and to improve item…

Research suggests that certain characteristics of survey items may impact participants' responses. In this study we investigated the impact of several of these characteristics: vague wording, question-versus-statement phrasing, and full-versus-partial labeling of response options. We manipulated survey items per these characteristics and randomly…

Web surveys are an established data collection mode that use written language to provide information. The written language is accompanied by visual elements, such as presentation formats and shapes. However, research has shown that visual elements influence response behavior because respondents sometimes use interpretive heuristics to make sense…

Low test-taking effort as a validity threat is common when examinees perceive an assessment context to have minimal personal value. Prior research has shown that in such contexts, subgroups may differ in their effort, which raises two concerns when making subgroup mean comparisons. First, it is unclear how differential effort could influence…

The aim of the current research was to provide recommendations to facilitate the development and use of anchoring vignettes (AVs) for cross-cultural comparisons in education. Study 1 identified six factors leading to order violations and ties in AV responses based on cognitive interviews with 15-year-old students. The factors were categorized into…

Self-assessment measures are commonly used in questionnaire surveys. However, one of the problems with self-reports is that they may be prone to differences in scale usage among respondents. The anchoring vignette method addresses this issue. It relies on two assumptions: response consistency and vignette equivalence. Here we aim to develop a…

Identifying and considering test-taking effort is of utmost importance for drawing valid inferences on examinee competency in low-stakes tests. Different approaches exist for doing so. The speed-accuracy+engagement model aims at identifying non-effortful test-taking behavior in terms of nonresponse and rapid guessing based on responses and…

Regulatory focus is a strong predictor for a person's behaviour in signal detection tasks. While a promotion focus is related to a risky response strategy (hits, false alarms), a prevention focus is associated with a conservative strategy (correct rejections, misses). The present research is based on the assumption that multiple-choice (MC)…

This study investigated the impact of students' test-taking effort on their growth estimates in reading. The sample consisted of 7,602 students (Grades 1 to 4) in the United States who participated in the fall and spring administrations of a computer-based reading assessment. First, a new response dataset was created by flagging both…

Contamination of responses due to extreme and midpoint response style can confound the interpretation of scores, threatening the validity of inferences made from survey responses. This study incorporated person-level covariates in the multidimensional item response tree model to explain heterogeneity in response style. We include an empirical…

Web, or online, probing has the potential to supplement existing questionnaire design processes by providing structured cognitive data on a wider sample than typical qualitative-only question evaluation methods can achieve. One of the practical impediments to the further integration of web probing is the concern of survey managers about how the…
