Claims of amnesia for criminal offenses: psychopathology, substance abuse, and malingering

The forensic psychiatric examiner often encounters defendants who deny memory for their offense. Past research proposes a variety of factors to account for offense amnesia. To date there have been few systematic studies of offense amnesia in relation to psychiatric diagnosis, either alone or in combination with other known factors such as substance use and malingering. We studied 53 pretrial felony defendants who had been referred for psychiatric examination; 40% claimed amnesia for their offense. Examinees with psychotic disorders in general, and schizophrenia in particular, were relatively less likely to claim amnesia than were examinees with other diagnoses. Substance use at the time of the offense and associated substance use disorder diagnoses were positively associated with offense amnesia. Malingering diagnosed by general clinical criteria was a poor predictor of amnesia claims. These data suggests that two prominent reasons for referral for forensic psychiatric evaluation include the presence of psychotic symptoms and claims of amnesia for the offense.

The role of the defense psychiatrist in workmen's compensation cases

Tomorrow's psychiatrist should be more cognizant, competent, and comfortable in forensic science matters. Psychiatric cases are increasingly the subjects of litigation, but justice in the court depends on able advocacy by all parties. Advocacy for patient-plaintiffs is more similar to customary clinical roles than is advocacy for defendant insurance companies, which nevertheless are as needful of competent psychiatric experts as patient-plaintiffs if justice is to be done. Ironically, defense psychiatrist can do much to help patient-plaintiffs if they understand their roles correctly. Since legal systems are designed to produce justice, not therapy, the forensic competence of future psychiatrists will help to make litigation more therapeutic and just for patients. This paper describes the peculiarities of psychiatric work in litigated workmen's compensation cases, focusing on the role of the defense psychiatrist. We will highlight the constructive and therapeutically gratifying potentials of this work. Greater familiarity with the process will help to enlist the interest and participation of psychiatrist in workmen's compensation cases for the ultimate benefit of the patients and improvement of the legal system.     

A study of amnesia in homicide cases and forensic psychiatric experts' examination of such claims

About one third of defendants in homicide cases claim amnesia during the time of their alleged act. Examining the authenticity of claimed amnesia is a special challenge for forensic experts. Because the experts' conclusions have legal implications, it is useful to study the characteristics of defendants who claim amnesia regarding a homicidal act and how forensic experts assess these defendants' claims. The forensic psychiatric reports from 2001 to 2007 on 102 Norwegian defendants charged with homicide were assessed quantitatively with a structured rating form. Due to multiple comparisons p of .003 was chosen. Twenty-six defendants claimed partial and 17 claimed total amnesia. No significant differences in the characteristics of the defendants were found between the partial, total, and no amnesia claiming groups. Claims of partial or total amnesia did not change the procedures and content of the forensic experts' examination. A memory test was applied in only one case. Despite the seriousness of the crime and the difficulty of assessing amnesia, the experts did not apply psychological testing of memory function or appropriate tests of possible malingering. Guidelines or standardized procedures for evaluation of defendants who claim amnesia should be developed. This could eventually contribute to more reliable and valid evaluations by forensic experts and increase the probability of just court outcomes.

Behind closed doors: the effect of pretrial publicity on jury deliberations

Abstract

Effective treatment of aggressive behaviour and accurate release decision making are necessary components of adequate clinical practice in forensic psychiatric units. Unfortunately, methods to identify treatment targets and ameliorate aggressive behaviour have developed at a slower pace than risk assessment technologies. Recent progress on the identification of offence paralleling or functionally equivalent behaviour offers a framework for individually tailored treatment and idiographic release decision making, although empirical scrutiny of this approach is inadequate. This paper describes an examination of the relationship between aggressive behaviour prior to admission with aggression during inpatient psychiatric treatment, and reconviction for violent offending following discharge. Results showed a relationship between pre- and post-admission aggression but no relationship between aggression during inpatient psychiatric treatment with either pre-admission aggressive behaviour or violent recidivism. These findings indicate the importance of state psychological variables, specifically those states affected by symptoms of psychiatric illness, as well as environmental activators and inhibitors of violence that operate within the hospital. These require inclusion in an adequate functional analysis of aggressive behaviour for forensic psychiatric patients.     

Survey of methods for the rating of psychiatric impairment in Australia

One of the enduring clinical issues in the assessment of plaintiffs in personal injury and workers' compensation claims, as well as applicants for social security and disablement benefits, is that of the evaluation of impairment and work incapacity. Many writers on this topic confuse the concepts of impairment and disability, and similar confusion is reflected in a number of the rating methods that purport to evaluate impairment but in reality assess disability. In Australia there are 20 distinct statutory schemes for workers' compensation, motor accident compensation, and social security and other benefits, which utilise a variety of methods for the rating of psychiatric impairment. Recent legislative changes designed to restrict access to personal injury compensation at common law, which in two Australian State jurisdictions require the use of impairment rating scales, also specify the rating methods to be used in the assessment of psychiatric impairment. This article discusses the concepts of impairment and disability as defined by the World Health Organisation, and reviews the various methods for the rating of psychiatric impairment that are specified by statute in the federal and State jurisdictions in Australia.

Diagnosis of antisocial personality disorder and criminal responsibility

The present study empirically investigates whether personality disorders and psychopathic traits in criminal suspects are reasons for diminished criminal responsibility or enforced treatment in high security hospitals. Recently, the tenability of the claim that individuals with personality disorders and psychopathy can be held fully responsible for crimes has been questioned on theoretical bases. According to some interpretations, these disorders are due to cognitive, biological and developmental deficits that diminish the individual's accountability.The current article presents two studies among suspects of serious crimes under forensic evaluation in a Dutch forensic psychiatric observation clinic. The first study examined how experts weigh personality disorders in their conclusions as far as the degree of criminal responsibility and the need for enforced forensic psychiatric treatment are concerned (n = 843). The second study investigated associations between PCL-R scores and experts' responsibility and treatment advisements (n = 108).The results suggest that in Dutch forensic practice, the presence of a personality disorder decreased responsibility and led to an advice for enforced forensic treatment. Experts also take characteristics of psychopathy concerning impulsivity and (ir)responsibility into consideration when judging criminal accountability. Furthermore, they deem affective deficiencies sufficiently important to indicate suspects' threat to society or dangerousness and warrant a need for forensic treatment.     

U.S. Industries v. Director: "claim" versus "condition" in the analysis of workers' compensation cases

Under most workers' compensation statutes, an injury must "arise out of " and "in the course of" employment in order to qualify as a compensable disability. In U.S. Industries v. Director, the Supreme Court held that the Longshoremen's and Harbor Workers' Compensation Act must be strictly construed to avoid transforming the compensation system into a form of social insurance. In U.S. Industries, the Court denied a disability claim based on an arthritic condition which was manifested while the worker was at home in bed. This Note contends that the Supreme Court neglected to consider pertinent medical realities when analyzing the causation question. Thus, the decision undermines the overall rationale behind workers' compensation legislation. Nonetheless, the Note argues that the case does not relax the requirement of adequately scrutinizing the causative elements underlying any reasonable claim for disability benefits. An analysis adequately accommodating both medical and legal facts, instead of relying upon the vagaries of statutory interpretation, is necessary to improve the efficiency and fairness of workers' compensation disability determinations.     

Work Impairment and Disability in Posttraumatic Stress Disorder: A Review and Recommendations for Psychological Injury Research and Practice

Work impairment and disability are common consequences of posttraumatic stress disorder (PTSD), as reflected by significant rates of sickness absence, failure to return to work, and reduced work performance. Within the psychological injury field, the issue of work impairment and disability in PTSD often arises in workers’ compensation and disability insurance claims and in personal injury litigation. In this context, clinical and forensic practitioners are faced with challenges in rendering expert opinions on diagnosis, causality, prognosis, and recommendations for treatment and rehabilitation. To promote understanding of this important, yet understudied area, there are three aims of this paper: first, to review the current literature on work impairment and disability associated with PTSD; second, to draw on this literature to present a biopsychosocial framework of work impairment and disability in PTSD; and third, to offer suggestions for improving the assessment and management of PTSD-related work impairment and disability.     

Forensic psychiatric inpatients and aggression: An exploration of incidence,prevalence, severity,and interventions by gender

BackgroundPrevious investigations suggest that women judged to be not criminally responsible on account of mental disorder (NCR-MD) differ markedly from their male counterparts in important ways, underscoring the necessity of subsequent study.ObjectiveThe goal of the present study was to inform our understanding of the presenting profile of female forensic psychiatric patients and contrast their risk of inpatient aggression with their male counterparts.MethodThe population of patients assessed and/or treated at a secure Canadian forensic psychiatric hospital were available for study. In total, 527 patients had complete data and were part of intensive retrospective file reviews; inpatient aggression was evaluated using the Overt Aggression Scale.ResultsWomen were no less likely than men to have a violent index offence and to perpetrate inpatient aggression. Examining the range of aggressive behaviours and severity levels did little to increase the relevance of gender to inpatient risk.DiscussionFemale forensic patients represent a highly selected subgroup of women with exceptional clinical and behavioural challenges and associated treatment needs.     

Contacts with public services, with special reference to mental health care, preceding a serious crime: a retrospective study of 268 subjects of forensic psychiatric investigations

Between July 1995 and June 1996, 533 subjects underwent forensic psychiatric investigation I Sweden. Odd case numbers (n = 268) were included in the study. Of these 268 people, 50% had been in contact with psychiatric services during the six-month period preceding the crime leading to forensic psychiatric assessment. Contacts with psychiatric services during the six-month period preceding the crime were significantly more common in three categories of individuals than others. These were: women, individuals who were diagnosed as having a psychotic disorder during the forensic psychiatric investigation, and individuals found to suffer from a serious mental disorder as defined in the legislation. Subjects who were found not to suffer from a serious mental disorder and were thus not eligible for special sanctions on medicolegal grounds had significantly less psychiatric contacts before the crime, as did subjects under 20 years of age. However, these two groups still had considerably more psychiatric contacts than the general population. The present results suggest that the patient category studied requires special monitoring and case management in general psychiatry in Sweden. To this end, we call for closer studies of high-risk individuals, particularly of previously violent offenders and potentially violent offenders, and closer studies of their psychiatric contacts. This will provide a basis for the development of adequate programs and guidelines for effective care and treatment within the psychiatric sector.     

Workers’ Compensation Claimants with Low Back Pain: the Role of Dissatisfaction in the Transition to Disability

Workers’ compensation systems represent naturalistic settings that often are perceived as unjust by the injured workers for which such systems were developed. This study examined the role of dissatisfaction with medical care and employer treatment on disability outcomes among a cohort of workers who had sustained low back injuries. A race-stratified sample of 358 workers (171 African-Americans, 203 Caucasians) with first incident low back pain was evaluated 21 months and again at 72 months after claim settlement. Evaluation included data related to demographics, socioeconomic factors, injury severity, claim settlement, satisfaction with workers’ compensation (WC) processes, and disability status. Multinomial logistic regression analysis was used to predict disability status (no disability vs. early disability vs. late disability) at each of the two time points. Analyses revealed contributions of multiple variables to early disability, including unique variance related to dissatisfaction with medical care and treatment by the employer. At 72 months, only demographic factors (age, race) and the receipt of temporary total disability (TTD) after injury predicted late disability. Results are discussed relative to the contribution of injustice perceptions and systemic factors; directions for future research are proposed.     

Homicide by a Forensic Female Sample in Brazil: A Preliminary Study

The objective of the study was to evaluate the mental status of all women (n = 14) who were acquitted by reason of insanity of charges of murder or attempted murder and committed to a forensic psychiatric hospital in the state of Rio de Janeiro, Brazil. All cases were retrospectively examined, including medical files, technical records, and forensic experts' official reports. A conclusive psychiatric diagnosis was established using the Structured Clinical Interview for DSM‐IV Axis I and II Disorders and clinical and forensic records. The most common diagnosis was schizophrenia/schizoaffective disorders (n = 8; 57.3%). Most victims (n = 12; 75%) were close relatives of the patients. We found that 43% (n = 6) of the patients had a previous history of violent behavior. According to the initial psychiatric forensic evaluation, 5 patients (35.7%) had psychotic symptoms. It is expected that a growing understanding of motivational factors underlying homicidal behavior in mentally disturbed female offenders may further the implementation of effective preventive and therapeutic interventions.     

Doing justice to justice

Adshead's recognition that only when taken together can the many different conceptions of justice accommodate what is called for in the particularly demanding setting of forensic mental health care, is to be applauded. Each must be honoured and built into the systems of assessment and treatment that are the tasks of the forensic psychiatrist, she demonstrates. Adshead's far‐reaching revisions could resolve much that is troubling about the present practice of forensic psychiatry. Yet how much these revisions can overcome the moral dilemmas associated with dual roles in forensic psychiatry, is not so clear.     

Problems of female patients in a secure psychiatric hospital

Abstract

The problems experienced by a sample of 30 female offender-patients in a secure psychiatric hospital were surveyed using the Behavioral Coding System (BCS). Common problems are emotional difficulties, antisocial behaviors, auditory hallucinations, and self-injury. Problem profiles derived from medical records, key workers' reports, and patients' self reports differed. The survey revealed the necessity of revising the BCS better to identify relevant concerns in this particular population.     

First report from the Swedish National Forensic Psychiatric Register (SNFPR)

To the best of our knowledge, the present register is the only nationwide forensic psychiatric patient register in the world. The aim of this article is to describe the content of the Swedish National Forensic Psychiatric Register (SNFPR) for Swedish forensic patients for the year 2010. The subjects are individuals who, in connection with prosecution due to criminal acts, have been sentenced to compulsory forensic psychiatric treatment in Sweden. The results show that in 2010, 1476 Swedish forensic patients were assessed in the SNFPR; 1251 (85%) were males and 225 (15%) were females. Almost 60% of the patients had a diagnosis of schizophrenia, with a significantly higher frequency among males than females. As many as 70% of the patients had a previous history of outpatient psychiatric treatment before becoming a forensic psychiatric patient, with a mean age at first contact with psychiatric care of about 20 years old for both sexes. More than 63% of the patients had a history of addiction, with a higher proportion of males than females. Furthermore, as many as 38% of all patients committed crimes while under the influence of alcohol and/or illicit drugs. This was more often the case for men than for women. Both male and female patients were primarily sentenced for crimes related to life and death (e.g., murder, assault). However, there were more females than males in treatment for general dangerous crimes (e.g., arson), whereas men were more often prosecuted for crimes related to sex. In 2010, as many as 70% of all forensic patients in Sweden had a prior sentence for a criminal act, and males were prosecuted significantly more often than females. The most commonly prescribed pharmaceuticals for both genders were antipsychotics, although more women than men were prescribed other pharmaceuticals, such as antidepressants, antiepileptics, and anxiolytics. The result from the present study might give clinicians an opportunity to reflect upon and challenge their traditional treatment methods.     

Fulfilling the bargain: how the science of ergonomics can inform the laws of workers' compensation

In the last decade, cumulative trauma disorders have become a significant percentage of reported workplace injuries and litigated workers' compensation claims. Arising from the accumulated impact of daily work activities on the body, these injuries do not fall neatly within either the "accident" or "disease" categories which comprise workers' compensation laws. As a result, courts and legislatures have struggled to properly evaluate workers' compensation claims for these injuries. This Note looks at the legal treatment of cumulative trauma injuries in light of the "original bargain" of workers' compensation, where workers give up a tort remedy against their employers in exchange for guaranteed, but limited, compensation for work-related injuries. In doing so, this Note undertakes a comprehensive comparison of litigated cumulative trauma cases in the tort and workers' compensation systems. Ultimately, this Note argues that judges must use the original bargain as an interpretive less when deciding cumulative trauma cases, and points to ergonomics--the science of the workplace--as a significant new tool for determining whether such injuries are work-related.     

A visualization approach to prioritizing insurance claims from complex,multi-PRP Superfund sites

Abstract

The severity of environmental insurance claims related to large multi-PRP Superfund sites has grown over the last 30?years. When an insured files a Superfund-related claim, allocated costs to the insured are typically unknown. Assessing the insured’s likely share of future cleanup costs is challenging. This article proposes a simple approach that allows claims professionals to visualize where their insured stands relative to other PRPs' potential allocation of cleanup costs. The resulting color-coded “heat map” allows claims professionals to easily assess and prioritize potential insured losses. It also provides a starting point for settlement negotiations, thus reducing frictional costs.
