Abstract
The malingered psychosis has increasingly occurred over the past few years due to the tendency towards care in the community and the closures of long-stay psychiatric institutions. Thus, it is required to identify malingered psychosis to reach accurate forensic assessments and inhibit misuse of restricted healthcare resources and miscarriages of justice. Despite the fact that some practical psychometric tools and strategies have been proposed for diagnosing true psychosis over the past decades, the differentiation between true psychosis and malingered psychosis is still sometimes challenging. Accordingly, it seems crucial to identify innovative and reliable diagnostic alternatives. Hence, the present article summarizes a collection of evidence that can be used by researchers to improve future assessment of oropharyngeal microbiome composition as a feasible diagnostic marker for true psychosis in a forensic psychiatric setting.

Abstract
This study examined the effectiveness of the negative distortion measures from the Personality Assessment Inventory (PAI) and Inventory of Problems-29 (IOP-29), by investigating data from a community and a forensic sample, across three different symptom presentations (i.e., feigned depression, posttraumatic stress disorder [PTSD], and schizophrenia). The final sample consisted of 513 community-based individuals and 288 inmates (total N = 801); all were administered the PAI and the IOP-29 in an honest or feigning conditions. Statistical analyses compared the average scores of each measure by symptom presentation and data source (i.e., community vs. forensic sample) and evaluated diagnostic efficiency statistics. Results suggest that the PAI Negative Impression Management scale and the IOP-29 are the most effective measures across all symptom presentations, whereas the PAI Malingering Index and Rogers Discriminant Function generated less optimal results, especially when considering feigned PTSD. Practical implications are discussed.

On the Use of Eye Movements in Symptom Validity Assessment of Feigned Schizophrenia. PSYCHOLOGICAL INJURY & LAW 2022.

Abstract
AbstractAssessing the credibility of reported mental health problems is critical in a variety of assessment situations, particularly in forensic contexts. Previous research has examined how the assessment of performance validity can be improved through the use of bio-behavioral measures (e.g., eye movements). To date, however, there is a paucity of literature on the use of eye tracking technology in assessing the validity of presented symptoms of schizophrenia, a disorder that is known to be associated with oculomotor abnormalities. Thus, we collected eye tracking data from 83 healthy individuals during the completion of the Inventory of Problems – 29 and investigated whether the oculomotor behavior of participants instructed to feign schizophrenia would differ from those of control participants asked to respond honestly. Results showed that feigners had a longer dwell time and a greater number of fixations in the feigning-keyed response options, regardless of whether they eventually endorsed those options (d > 0.80). Implications on how eye tracking technology can deepen comprehension on simulation strategies are discussed, as well as the potential of investigating eye movements to advance the field of symptom validity assessment.

Abstract
The purpose of this study was to determine how malingered PTSD behavior affects the performance of a continuous performance task (CPT). An analog trauma group, two malingering groups (with or without educational intervention), and a control group were organized according to simulation design. During the CPT, the numbers of errors and response time indicators along with post-error slowing (PES) and recovery (PER) process were measured. Results are as follows: First, the analog trauma group showed deficits of response inhibition and a higher level of PES compared to the control group. Second, malingered PTSD caused a significant number of errors, inconsistent performance, and no PES. Third, there was a significantly more impaired and inconsistent performance in the low level of knowledge of disability. Finally, a discriminant accuracy of more than 90% appeared in the discriminant analysis of all group comparison conditions. Taken together, the results of this study show that post-error behavior indicators are affected by malingered PTSD, and differences according to the degree of knowledge of PTSD can also be confirmed. These results are expected to be used as basic data for the development of tasks for the detection of malingerers in clinical scenes in the future.

Abstract
Auditory verbal hallucinations (AVH) frequently cause significant distress and dysfunction, and may be unresponsive to conventional treatments. Some voice-hearers report an ability to fully control the onset and offset of their AVH, making them significantly less disruptive. Measuring and understanding these abilities may lead to novel interventions to enhance control over AVH. Fifty-two voice-hearers participated in the pilot study. 318 participants with frequent AVH participated in the validation study. A pool of 59 items was developed by a diverse team including voice-hearers and clinicians. After the pilot study, 35 items were retained. Factorial structure was assessed with exploratory (EFA, n = 148) and confirmatory (CFA, n = 170) factor analyses. Reliability and convergent validity were assessed using a comprehensive battery of validated phenomenological and clinical scales. CFA on the final 18 items supported two factors for a Methods of Control Scale (5 items each, average ω = .87), and one factor for a Degree of Control Scale (8 items, average ω = .95). Correlation with clinical measures supported convergent validity. Degree of control was associated with positive clinical outcomes in voice-hearers both with and without a psychosis-spectrum diagnosis. Degree of control also varied with quality of life independently of symptom severity and AVH content. The Yale control over perceptual experiences (COPE) Scales robustly measure voice-hearers' control over AVH and exhibit sound psychometric properties. Results demonstrate that the capacity to voluntarily control AVH is independently associated with positive clinical outcomes. Reliable measurement of control over AVH will enable future development of interventions meant to bolster that control.

Abstract
AbstractResearch on malingering detection has not yet taken full advantage of eye tracking technology. In particular, while several studies indicate that patients with schizophrenia behave notably differently from controls on specific oculomotor tasks, no study has yet investigated whether experimental participants instructed to feign could reproduce those behaviors, if coached to do so. Due to the automatic nature of eye movements, we anticipated that eye tracking analyses would help detect feigned schizophrenic problems. To test this hypothesis, we recorded the eye movements of 83 adult UK volunteers, and tested whether eye movements of healthy volunteers instructed to feign schizophrenia (n = 43) would differ from those of honest controls (n = 40), while engaging in smooth pursuit and pro- and anti-saccade tasks. Additionally, results from our investigation were also compared against previously published data observed in patients with schizophrenia performing similar oculomotor tasks. Data analysis showed that eye movements of experimental participants instructed to feign (a) only partially differed from those of controls and (b) did not closely resemble those from patients with schizophrenia reported in previously published papers. Taken together, these results suggest that examination of eye movements does have the potential to help detecting feigned schizophrenia.

Abstract
Malingering is the intentional fabrication of symptoms for material gain. Malingering among frequent utilizers and patients with psychiatric symptoms is suspected to be common in emergency settings but difficult to detect and manage. We present a case report of a 50-year-old man feigning psychosis and suicidality in order to obtain shelter. Strategies to identify malingered psychiatric symptoms are presented. Understanding how malingering is adaptational can help clinicians begin to manage these patients and symptoms in a compassionate manner that preserves healthcare resources, improves patient care, and reduces the risk of burnout for clinicians.

Abstract
The first part of the series of three articles on posttraumatic stress disorder (PTSD) in Court to appear in the journal reviews the history of the construct of PTSD and its presentation in the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition; American Psychiatric Association, 2013) and the ICD-11 (International Classification of Diseases, 11th Edition; World Health Organization, 2018). There are 20 symptoms of PTSD in the DSM-5. PTSD symptoms are arranged into a four-cluster model, which has received partial support in the literature. Other four-factor models have been found that fit the data even better than that of the DSM-5. There is a five-factor dysphoria model and two six-factor models that have been found to fit better the DSM-5 PTSD symptoms. Finally, research is providing support for a hybrid seven-factor model. An eighth factor on dissociation seems applicable to the minority of people who express the dissociative subtype. At the epidemiological level, individuals can expect trauma exposure to take place about 70% over one's lifetime. Also, traumatic exposure leads to traumatic reactions in about 10% of cases, with PTSD being a primary diagnosis for trauma. Once initiated, PTSD becomes prolonged in about 10% of cases. Polytrauma and comorbidities complicate these prevalence statistics. Moreover, the possibility of malingered PTSD presents confounds. However, the estimate for malingered PTSD varies extensively, from 1 to 50%, so that the estimate is too imprecise for use in court without further research. This first article in the series of three articles appearing in the journal on PTSD in Court concludes with discussion of complications related to comorbidities and heterogeneities, in particular. For example, PTSD and its comorbidities can be expressed in over one quintillion ways. This complexity in its current structure in the DSM-5 speaks to the individual differences involved in its expression.

Abstract
Few changes were made to the diagnostic criteria for schizophrenia in DSM-5. Schizophrenia is a chronic mental illness with positive symptoms (delusions, hallucinations, disorganized speech and behavior), negative symptoms, and cognitive impairment. Discoveries in genetics, neuroimaging, and immune function continue to advance understanding of the etiologies for this elusive disease. The authors reviewed the current literature to give an overview. The topics include historical foundations, epidemiology, suicide risk, genomewide association studies, twin studies, neuroimaging, ventricular size, complement component 4 mediated synapse elimination, major histocompatibility complex markers, and associations seen in obstetrical complications, nutritional issues, prodromal and attenuated states, cannabis use, childhood trauma, immigration, and traumatic brain injury. Also reviewed are expressed emotions of caregivers and recidivism, conditions comorbid with obsessive-compulsive disorder, mood disorders, substance use, and finally some legal and ethical issues. These important developments in elucidating the disease mechanism will likely allow for the development of future novel treatment strategies.

Abstract
The paper outlines the difference between the so-called normal (common) lying and pathological lying. Pathological lying is an intriguing topic, still lacking any strong professional consensus, clear etiology, treatment options and prognoses. The paper explores some possible psychological mechanisms of pathological lying, reviews biological factors in pathological lying, and considers forensic significance of normal and pathological lying. The relationship between pathological lying and mental disorders is also discussed. The authors suggest that lying should be considered as a heterogenic and multidimensional behavioral pattern. The paper highlights how important it is to assess the patient's control over lying, the function of lying, insight into and awareness of lying, as well as the effect of lying on everyday functioning.

Abstract
Correctional facilities are a major provider of mental health care throughout the United States. In spite of the numerous benefits of providing care in this setting, clinicians are sometimes concerned about entering into correctional care because of uncertainty in prescribing practices. This article provides an introduction to prescription drug use, abuse, and diversion in the correctional setting, including systems issues in prescribing, commonly abused prescription medications, motivation for and detection of prescription drug abuse, and the use of laboratory monitoring. By understanding the personal and systemic factors that affect prescribing habits, the clinician can develop a more rewarding correctional practice and improve care for inmates with mental illness.

Abstract
While auditory hallucinations (AH) are prototypic psychotic symptoms whose clinical presence is often equated with a psychotic disorder, they are commonly found among those without mental illness as well as those with nonpsychotic disorders not typically associated with hallucinations in DSM-IV. This incongruity presents a significant challenge for clinical work and efforts to revise the next iteration of the DSM. Auditory hallucinations found among "normal" people suggest that either AH are not as pathologic as they are typically taken to be, or that less-than-hallucinatory experiences are routinely mischaracterized as AH. Such hallucinations in the context of conversion disorder, trauma, sensory deprivation, and certain cultural settings strengthen an association between AH and psychopathology but suggest limited diagnostic specificity and relevance. It may be useful to think of AH like coughs-common experiences that are often, but not always, symptoms of pathology associated with a larger illness. Although these issues have been known for many years, they are rarely discussed in American psychiatry and need to be addressed in future research and clinical work.

Abstract
Malingering presents special challenges to the practicing clinician, including diagnostic uncertainty, the confrontation of potentially criminal conduct, and countertransference and personal reactions. Maintaining a traditional clinical approach to the patient suspected of malingering enables the therapist to draw analogies to other disorders and utilize customary diagnostic and therapeutic skills. Malingering has long been recognized in the military, and has predictably come to the forefront of clinical practice during a time of war. The art in military medicine is to find a way to make our ethical and fiduciary responsibility to act in the best interest of the patient coincide with the needs of the system. In this context, malingering can also be viewed as an immature or primitive defense in a very stressful situation, and approached accordingly. This article discusses key elements of the history and mental status examination in the clinical assessment of malingering, and therapeutic analogies that offer the possibility of a positive outcome for an otherwise potentially negative encounter.

Abstract
OBJECTIVE To describe a patient with feigned psychosis who was admitted to an acute psychiatric unit under the Mental Health Act, and to discuss the clinical features of malingering in this treatment setting. METHOD Case report. RESULTS A 40-year-old man with no known past psychiatric history was brought by police to the Emergency Department. He gave a history of paranoia, hallucinations and bizarre behaviour and was admitted to a secure ward. Treatment with parenteral medication was required due to hostile and aggressive behaviour. Collateral history was inconsistent with his reported symptoms and, when confronted with this information, he acknowledged fabricating his symptoms in order to obtain a disability pension. CONCLUSIONS It is important to consider malingering as a differential diagnosis in patients who present with atypical features and have clear external incentives for their behaviour. With improved health literacy and access to health information, individuals who are marginalized in society and have limited social and occupational opportunities may malinger symptoms for obvious personal gain. Inconsistency between reported symptoms and clinical observations, as well as contradictory collateral information from multiple sources, are helpful tools in diagnosing malingering. It is important for clinicians to identify malingerers early and limit unnecessary admissions.

Abstract
OBJECTIVE This paper aims to study the detection of individuals malingering posttraumatic stress disorder (PTSD) in criminal and civil situations. METHOD A brief history of PTSD and its rise to prominence in legal circles are discussed. The characteristics of individuals who malinger and particularly those who fake PTSD are discussed. Diagnostic dilemmas inherent to the condition, such as the definition of a traumatic exposure, what constitutes a PTSD flashback and the potential for normal symptom exaggeration, are explored. RESULTS The typical presentation of malingered symptoms is presented to help clinicians detect commonly seen malingering patterns. Suggestions for interview techniques, Minnesota Multiphasic Personality Inventory test values and sources of collateral information to help detect malingering are reviewed. CONCLUSION The paper concludes with a review of the typical presentations of malingered PTSD symptoms and a reminder that physicians need to distinguish legitimate symptoms from faked or embellished presentations.

Abstract
Lying and deception are behaviors that have been studied and discussed extensively in the scientific, philosophical and legal communities for centuries. The purpose of this article is to provide a general overview of the literature and thinking to date about deception, followed by an analysis of the efficacy and evolution of lie detection techniques. The first part explores the definitions of lying, from animal behaviorists' perspectives to philosophical theories, along with demographics and research about the prevalence of lying and characteristics of those who lie. This is followed by a discussion of possible motivations for lying, moral arguments about the legitimacy of or prohibition against lying, and developmental theorists' explanations for the growth of a human being's capacity to lie. The first section provides an introduction for the second part, a historical and critical review of lie detection techniques. Early methods, such as phrenology and truth serums are contrasted with more modern-day approaches, such as polygraphy and functional MRIs. Conclusions are drawn about whether technology has really advanced the art of detecting deception. Finally, the article enters a discussion about the law's response to lie detection methods and to deception in general. United States landmark cases, at both the state and federal level, are critiqued with regard to their impact on the admissibility into court of lie detection methods as evidence. Just as the scientific community has been wary of embracing many of these methods, so has the legal community. Through a review of the legal, scientific and pseudo-scientific issues surrounding deception, a greater understanding is reached of the complexity of this universal and morally loaded behavior.
