Data collected during psychoeducational evaluations can be compromised by response bias: clients not putting forth sufficient effort on tests, not being motivated to do well, or not being fully honest and careful when completing rating scales and contributing similar self-report data. Some of these problems apply to data from third-party…

To improve the validity of self-report measures, researchers should control for response style (RS) effects, which can be achieved with IRTree models. A traditional IRTree model considers a response as a combination of distinct decision-making processes, where the substantive trait affects the decision on response direction, while decisions about…

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…

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…

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…

Questionnaires routinely measure unipolar and bipolar constructs using rating scales. Such rating scales can offer odd numbers of points, meaning that they have explicit middle alternatives, or they can offer even numbers of points, omitting the middle alternative. By examining four types of questions in six national or regional telephone surveys,…

Insincere respondents can have an adverse impact on the validity of substantive inferences arising from self-administered questionnaires (SAQs). The current study introduces a new method for identifying potentially invalid respondents from their atypical response patterns. The two-step procedure involves generating a response inconsistency (RI)…

Even though there is an increasing interest in response styles, the field lacks a systematic investigation of the bias that response styles potentially cause. Therefore, a simulation was carried out to study this phenomenon with a focus on applied settings (reliability, validity, scale scores). The influence of acquiescence and extreme response…

This document describes the following two new student engagement metrics now included on NWEA™ MAP® Growth™ reports, and provides guidance on how to interpret and use these metrics: (1) Percent of Disengaged Responses; and (2) Estimated Impact of Disengagement on RIT. These metrics will inform educators about what percentage of items from a…

Psychologists have become increasingly interested in the intra-individual variability of psychological measures as a meaningful distinguishing characteristic of persons. Assessments of intra-individual variability are frequently based on the repeated administration of self-report rating scale instruments, and extreme response style (ERS) has the…

To measure the response style of acquiescence, researchers recommend the use of at least 15 items with heterogeneous content. Such an approach is consistent with its theoretical definition and is a substantial improvement over traditional methods. Nevertheless, measurement of acquiescence can be enhanced by two additional considerations: first, to…

In this study, we investigated how empirical indicators of test-taking engagement can be defined, empirically validated, and used to describe group differences in the context of the Programme of International Assessment of Adult Competences (PIAAC). The approach was to distinguish between disengaged and engaged response behavior by means of…

Even when relatively infrequent, careless and random responding (C/RR) can have robust effects on individual and group data and thereby distort clinical evaluations and research outcomes. Given such potential adverse impacts and the broad use of self-report measures when appraising addictions and addictive behavior, the detection of C/RR can…

Previous research has found the effects of acquiescence to be generally consistent across item "aggregates" within a single survey (i.e., essential tau-equivalence), but it is unknown whether this phenomenon is consistent at the" individual item" level. This article evaluated the often assumed but inadequately tested…

The use of psychological tests to help identify the noncredible overreporting of psychiatric disorders is a long-standing practice that has received considerable attention from researchers. The purpose of this study was to experimentally determine whether feigning specific psychiatric disorders moderated the influence of coaching on the detection…
