“…In previous research, these items were found to be most effective in separating instructed malingerers from honest responding participants 16 . Note also that several studies have demonstrated that even a small set of well-chosen validity items can distinguish careful from careless or exaggerating respondents 10,15,17 .…”

-Background and Objectives:The potential link between dissociative symptoms and symptom over-reporting has been given little attention. In two student samples (N's = 139 and 113) and a clinical sample (N = 21), we examined whether self-reported dissociative symptoms are related to symptom over-reporting.Methods: We relied on different measures of dissociation and over-reporting. In the clinical sample, we looked at whether the well-established link between dissociative symptoms and sleep disturbances would survive if we corrected for symptom over-reporting.Results: Dissociativity correlated with symptom over-reporting in the student samples, but not in the clinical sample. Correcting for over-reporting tendencies did not fundamentally alter the relationships between dissociative symptoms and sleep disturbances in the clinical sample.Conclusions: Our results suggest that the overlap between symptom over-reporting and dissociativity is much more a problem in nonclinical than in clinical samples.

Identifying psychological vulnerabilities: Studies on police suspects’ mental health issues and police officers’ views

2018

Psychological vulnerabilities in police suspects may interfere with the demands of police interrogations, and thereby increase the risk of an unreliable statement, or even a false confession. This study examined: (1) the prevalence of a number of psychological vulnerabilities in police arrestees, and (2) the views of police officers on identifying vulnerable suspects. Both have not been studied previously in the Dutch context. Psychological assessments of a sample of police suspects (N = 149) showed that about 60% rated positive on a mental health screen, and, compared to the general Dutch population, levels of psychopathology, depression, anxiety, stress and interrogative suggestibility were significantly higher. In a second study in police detectives (N = 103), 55% stated that they had not interrogated a vulnerable suspect within the previous 12-month period, and again 55% mentioned that they did not take any special precautions when interrogating vulnerable suspects. Forty-two per cent of police detectives took precautions when interrogating vulnerable suspects, such as consulting their supervisor, a police psychologist, the public prosecutor or a specialised police interrogator. The two studies together indicate that police officers seriously underestimate the base rate of psychological vulnerabilities among suspects. Implications for police interrogation training and supervision are provided.

The total score of the WCS is the sum of the scores of all items (range = 0 -16), and a score of 4 or higher serves as an indication for malingering (Merckelbach et al, 2014).…”

“…To check for malingering (simulation of physical and psychological symptoms), we used a short form (SF) of the Wildman Symptom Checklist (WCS; Wildman & Wildman, 1999). The WCS SF contains four items about serious but non-credible symptoms that have proven to be a reliable predictor of malingering (Merckelbach, Smeets, & Jelicic, 2008;Merckelbach, Langeland, De Vries, & Draijer, 2014). An example of a WSC item is: 'Sometimes I have such a bad headache that my feet hurt'.…”

“…All interrogation transcripts were anonymised after the analyses.This study was approved by the standing Ethical Review Committee Psychology and Neuroscience of Maastricht University (ERCPN number: 03_10_2014), the Office of the Attorney General of the Netherlands, the Chief Constable of the Dutch National Police Force.Measures MalingeringIn order to detect possible malingering of symptoms, a short form (SF) of the Wildman Symptom Checklist (WSC;Wildman & Wildman, 1999) was included in the assessment battery. Previous research found that out of the original 70 items of the WCS, four items discriminated optimally between respondents who were asked to answer honestly and respondents asked to exaggerate symptoms(Merckelbach, Smeets, & Jelicic, 2008;Merckelbach, Langeland, De Vries, & Draijer, 2014). The four items of the WSC SF concern non-credible, yet disturbing, cognitive symptoms: 'I have headaches that are so severe my feet hurt', 'The buzzing in my ears keeps switching from the left to the right', 'I notice that the colour of things around me keeps shifting', and 'I find myself frequently blacking out when I sit down.'…”
