The prevalence of feigning and concealment of Covid-19 infections in an international sample.

We asked 463 participants from 21 countries whether they had feigned and/or concealed having a coronavirus infection during the pandemic period. 384 respondents (83%) reported having experienced a coronavirus infection. They were, on average, younger and reported more chronic health issues than participants who said they had never been infected.

#StudentsToo. prevalence of sexual assault reports among students of three European universities and their actions post-assault.

Objective: Previous research has indicated high rates of sexual assault (SA) among US students (> 25%). Yet this type of investigation has been less frequent at European universities.

Methods: We conducted an investigation at three universities, two Dutch universities (N = 95 and N = 305) and one university in Belgium (N = 307).

The Impact of Different Forms of Coaching on the Structured Inventory of Malingered Symtomatology (SIMS).

Background: Psychometric symptom validity instruments (SVTs) can be vulnerable to coaching, which can negatively affect their performance. Our aim was to assess the impact that different types of coaching may have on the sensitivity of the Structured Inventory of Malingered Symptomatology (SIMS).

Methods: A simulation design was used with 232 non-clinical adults divided into five experimental simulation conditions and 58 patients with anxious-depressive symptomatology derived from a traffic accident.

The English-language version of the Self-Report Symptom Inventory: a pilot analogue study with feigned head injury sequelae.

Questionnaire-based symptom validity tests (SVTs) are an indispensable diagnostic tool for evaluating the credibility of patients' claimed symptomatology, both in forensic and in clinical assessment contexts. In 2019, the comprehensive professional manual of a new SVT, the Self-Report Symptom Inventory (SRSI), was published in German. Its English-language version was first tested in the UK.

Prevalence Estimates of Symptom Feigning and Malingering in Spain.

Symptom feigning and malingering should be evaluated in forensic contexts due to their important socio-economic consequences. Despite this, to date, there is little research in Spain that evaluates its prevalence. The aim of this study was to investigate this issue using the perception of the general population, students, and professionals of medicine and forensic psychology.

Symptom coaching and symptom validity tests: An analog study using the structured inventory of malingered symptomatology, Self-Report Symptom Inventory, and Inventory of Problems-29.

In this pilot and exploratory study, we tested the robustness of three self-report symptom validity tests (SVTs) to symptom coaching for depression, with and without additional information available on the Internet. Specifically, we divided our sample ( = 193) so that each subject received either the Structured Inventory of Malingered Symptomatology (;  = 64), the Self-Report Symptom Inventory (;  = 66), or the Inventory of Problems-29 (;  = 63). Within each of the three subgroups, approximately one third of participants were instructed to respond honestly (Genuine Condition, = 21; = 24; = 26) and approximately two-thirds were instructed to feign depression.

Presenting the consequences of feigning: Does it diminish symptom overendorsement? An analog study.

Feigning causes personal and societal consequences, in both civil and criminal context. We investigated whether presenting the consequences of feigning can diminish symptom endorsement in feigned Posttraumatic Stress Disorder (PTSD). We randomly allocated non-native English speaking undergraduates ( = 145) to five conditions: 1) Truth tellers ( = 31), 2) Civil context feigners ( = 27), 3) Civil context warned feigners ( = 26), 4) Criminal context feigners ( = 29), and 5) Criminal context warned feigners ( = 32).

Consistency does not aid detection of feigned symptoms, overreporting does: Two explorative studies on symptom stability among truth tellers and feigners.

Practitioners always want to exclude the possibility that a patient is feigning symptoms. Some experts have suggested that an inconsistent symptom presentation across time (i.e.

Overlooking Feigning Behavior May Result in Potential Harmful Treatment Interventions: Two Case Reports of Undetected Malingering.

Clinicians tend to overestimate their ability to recognize feigning behavior in psychiatric patients, especially if it concerns patients who have been admitted for observation. Feigning can be either externally motivated (e.g.

Detecting feigned high impact experiences: A symptom over-report questionnaire outperforms the emotional Stroop task.

Background And Objectives: The Modified Stroop Task (MST) effect refers to a prolonged reaction time (RT) in color-naming words related to an individual's disorder. Some authors argue that its absence in people who claim symptoms might be an indication of feigning.

Method: We tested whether the MST effect is robust against feigning attempts and compared its absence as an index of feigning with over-reporting tendencies on a symptom questionnaire (i.

The Modified Stroop Task Is Susceptible to Feigning: Stroop Performance and Symptom Over-endorsement in Feigned Test Anxiety.

Some researchers argue that the modified Stroop task (MST) can be employed to rule out feigning. According to these authors, modified Stroop interference effects are beyond conscious control and therefore indicative of genuine psychopathology. We examined this assumption using a within-subject design.

Verifiability on the run: an experimental study on the verifiability approach to malingered symptoms.

Several studies on the verifiability approach found that truth-tellers report more verifiable details than liars. Therefore, we wanted to test whether such a difference would emerge in the context of malingered symptoms. We obtained statements from undergraduates ( = 53) who had been allocated to three different conditions: truth-tellers, coached malingerers and naïve malingerers.

Posttraumatic Stress Disorder and Diminished Criminal Responsibility as "New Evidence" in Criminal Revision Procedures.

Posttraumatic stress disorder (PTSD) may affect victims of crime, but may also be reported by offenders. In the postappeal phase, offenders may claim to suffer from chronic PTSD and argue that this indicates diminished criminal responsibility at the time the index crime was committed. As members of a Dutch criminal cases review commission, we recently encountered two cases in which PTSD was presented as new evidence that would justify a reopening of the case.

Alexithymia as a potential source of symptom over-reporting: An exploratory study in forensic patients and non-forensic participants.

The traditional interpretation of symptom over-reporting is that it indicates malingering. We explored a different perspective, namely that over-reporting of eccentric symptoms is related to deficits in articulating internal experiences (i.e.

Plausibility Judgments of Atypical Symptoms Across Cultures: an Explorative Study Among Western and Non-Western Experts.

Symptom validity tests (SVTs) are predicated on the assumption that overendorsement of atypical symptoms flags symptom exaggeration (i.e., questionable symptom validity).
