The current study evaluated a brief, informant-based autism interview: the Developmental, Dimensional and Diagnostic Interview -- Adult Version (3Di-Adult). Feasibility, reliability and validity of the Dutch 3Di-Adult was tested amongst autistic participants (n = 62) and a non-autistic comparison group (n = 30) in the Netherlands. The 3Di-Adult…

The current experiment examined the effects of combining two interview techniques on information elicitation and lie detection in multiple interviews. Participants were interviewed online over three weeks. Two-thirds of the participants (n = 114) were presented with the model statement (MS) interview technique in Interview 1 and were asked to…

The putative confession (PC) instructions ("[suspect] told me everything that happened and wants you to tell the truth") increases children's honesty. However, research has shown that children who maintain secrecy despite the PC are more convincing. We examined whether (a) the PC undermines adults' deception detection abilities or (b)…

The Self-Administered Interview (SAI©) is designed to elicit detailed witness reports in the aftermath of incidents. In two sets of meta-analyses, we compared the number of correct details reported, the number of incorrect details reported, and the accuracy of reports provided by witnesses in initial reports (SAI© vs. other reporting formats) and…

Introduction: Young people with intellectual disabilities (ID) are at an increased risk for experiencing mental health issues compared to their peers without disabilities. Further, there are limited resources available to help accurately assess mental health disorders and that are accessible for adolescents with ID. Method: This paper describes…

Identifying illicit behavior in survey research is inherently problematic, since self-reports are untrustworthy. We argue that fraudulent interviewers can, however, be identified through statistical deviance of the distributional parameters of their interviews. We document that a high proportion of the variation in the data is due to the…

Sketching while narrating involves describing an event while sketching on a blank paper (self-generated sketch) or on a printed map. We compared the effects of self-generated sketches and printed maps on information elicitation and lie detection. Participants (N = 211) carried out a mock mission and were instructed to tell the truth or to lie…

Sham marriages occur frequently, and to detect them, partners are sometimes interviewed together. We examined an innovative method to detect deceit in such interviews. Fifty-three pairs of interviewees, either friends (truth tellers) or pretended to be friends (liars), were interviewed about their friendship. Just before the interview, they…

There is an increasing need for cross-cultural qualitative studies in an era of globalization. A focus group of five researchers, who were involved in a large international research project, identified effective strategies and challenges associated with five key domains of qualitative research with key informants: identification, recruitment,…

In information gathering interviews, follow-up questions are asked to clarify and extend initial witness accounts. Across two experiments, we examined the efficacy of open-ended questions following an account about a multi-perpetrator event. In Experiment 1, 50 mock-witnesses used the timeline technique or a free recall format to provide an…

Few studies have investigated eyewitnesses' ability to predict their later lineup performance, known as "predecision confidence." We applied calibration analysis in two experiments comparing predecision confidence (immediately after encoding but prior to a lineup) to postdecision confidence (immediately after a lineup) to determine which…

The verifiability approach (VA) is a lie-detection tool that examines reported checkable details. Across two studies, we attempt to exploit liar's preferred strategy of repeating information by examining the effect of questioning adult interviewees before the VA. In Study 1, truth tellers (n = 34) and liars (n = 33) were randomly assigned to…

Cross-cultural qualitative research is essential to develop practical approaches to promote adult education and training in diverse societies. Yet, little systematic guidance is available to successfully conduct a large-scale cross-national qualitative inquiry in general, and in virtual settings in particular. The purpose of this study is to…

Research has begun to investigate the reliability of cannabis-intoxicated eyewitnesses; however, no studies have evaluated eyewitness memory among chronic cannabis users after a minimum 24-h abstinence. This study compared cannabis users' (n = 23) and nonusers' (n = 26) eyewitness recall/identification and investigated the relationship between…

Decades of empirical research has demonstrated that exclusionary discipline is a racialized mechanism through which schools systematically remove Black and brown children from the learning environment. Although development of Functional Behavior Assessments (FBAs) and linked behavior support plans has been identified as a solution to exclusionary…
