应激与海马

综述了近年来应激对海马形态和功能影响及海马对应激(HPA轴)调节的研究进展。研究表明,由于海马参与应激的感知、整合与评价,参与HPA轴应激反应,应激影响其结构与功能;而海马又可通过负反馈调节,抑制HPA轴的过度应激反应。但长期慢性应激则可削弱这种抑制作用,加重海马结构与功能的损害。     

儒家思想与压力应对:应激研究的本土心理学视角

儒家式应对思想包括对压力的认知以及针对压力的应对行为。儒家面对挫折和困苦的态度是坦然的,艰难困苦是成长必须经历的。当压力与困境超出个人能力时,儒家引入"命"的概念来缓解个人面临重大压力时的挫折感。儒家强调从个人的内在修养和外在行为这两方面来应对压力。儒家式应对突破了西方应对观中仅重视非精神性应对方式的局限,融合了精神性与非精神性的应对方式,是源自本土的有效应对方式之一,也是理解中国人民族特性的重要切入点。     

Critical Stress: Police Officer Religiosity and Coping with Critical Stress Incidents

As a result of exposure to critical stress inducing incidents, police officers experience high rates of family disruption, alcohol abuse, domestic violence, and physical and psychological problems. This paper evaluates the ability of religion to mitigate the harmful consequences of critical stress using data obtained from a survey of metropolitan police officers (n?=?811). Contrary to our expectations, we found less religious officer used more adaptive coping strategies when confronted by critical stress incidents than their more religious counterparts. Furthermore, we found Protestants employed more adaptive strategies than Catholics. Potential explanations for the unexpected findings are discussed.

Assessment of Stress and Resiliency in Emergency Dispatchers

Although they are technically the first responders on most critical incidents, emergency dispatchers have received a modicum of attention from researchers and clinicians. The purpose of the present study was to evaluate job-related stress, psychological distress, posttraumatic stress disorder (PTSD), stress resiliency, and posttraumatic growth in this high-risk group. These areas were evaluated via an assessment battery administered to 90 emergency dispatchers working in a law enforcement agency. Results showed that dispatchers experienced an average amount of occupational stress, with 24% of the current sample reporting significant job stress. Between 13.34 and 15.56% reported symptoms consistent with a PTSD diagnosis, and 16.67% indicated sub-threshold PTSD symptomatology. The findings revealed that, overall, dispatchers experience occupational stress, psychological distress, and sub-threshold PTSD at similar or higher rates compared to police officers. Further, dispatchers reported posttraumatic growth at an average rate, also similar to that reported by police officers. Clinical implications of the results are discussed. Suggestions for directions that future research might take are offered.     

Posttraumatic Stress Disorder: Current Concepts and Controversies

The diagnosis of posttraumatic stress disorder (PTSD) sometimes is raised in compensation claims, in tort settings, and in other medical–legal settings. Accordingly, health-care and legal professionals working in these areas need to be familiar with the current findings and controversies concerning the disorder. The purpose of this article is twofold. First, we review the most important findings concerning the clinical features, etiology, and treatment of PTSD. Second, we examine six major controversies concerning the disorder that are relevant to psychologists and other medical–legal practitioners: (a) the issue of what qualifies as a traumatic stressor, (b) the question of whether traumatic stress causes brain damage, (c) the validity of the concept of delayed-onset PTSD, (d) the recovered memory controversy, (e) the question of whether PTSD can arise when the person has no memory of the trauma (e.g., due to concussion), and (f) issues concerning PTSD malingering. Throughout this article we offer recommendations for psychological and other medical–legal practice in relation to the evaluation of PTSD claims.     

Early Repolarization,Acute Emotional Stress and Sudden Death

We herein report the case of a 36‐year‐old man who died suddenly after a fight with another man. Forensic investigations included unenhanced computed tomography, postmortem angiography, autopsy, histology, neuropathology, toxicology, and biochemistry and allowed a traumatic cause of death to be excluded. An electrocardiogram recorded some years prior to death revealed the presence of an early repolarization pattern. Based on the results of all investigations, the cause of death was determined to be cardiac arrhythmia and cardiac arrest during an emotionally stressful event associated with physical assault. Direct third party involvement, however, was excluded, and the manner of death was listed as natural. The case was not pursued any further by the public prosecutor.     

Neuropsychological and Psychological Aspects of Malingered Posttraumatic Stress Disorder

Posttraumatic stress disorder (PTSD) is an anxiety disorder that is frequently encountered in litigation, and as such, there is an increased risk for poor effort on cognitive tests, symptom exaggeration, or frank malingering. These are particularly problematic for accurate diagnosis. This article is divided into four sections. First, we address why individuals malinger PTSD as well as the challenges in detecting an invalid PTSD symptom presentation. Second, we discuss issues of cognitive functioning in PTSD and then the prevalence of and common patterns of poor effort on neuropsychological testing among individuals feigning PTSD. Third, we discuss psychological functioning in PTSD and then the prevalence and patterns of functioning on psychological measures of malingering in this population. Finally, recommendations for detecting invalid PTSD symptom presentations are provided.     

Posttraumatic Stress Disorder: Assessing Response Style and Malingering

Posttraumatic stress disorder (PTSD) may form the basis for disability or worker’s compensation claims or a personal injury lawsuit. While now achieving widespread acceptance among treating professionals and the public, PTSD is the subject of several controversies and the possibility of faking in a compensation context. There appears to be a dramatic split among mental health professionals who write primarily from a treatment or plaintiff perspective and those who take a more skeptical approach. This article reviews recent developments in the assessment of malingering, including symptom validity measures, and applies them to the assessment of PTSD. Recommendations for current practice are provided.     

Civilian Forensic Technician and Sworn Police Officer Job-Related Stress

Forensic Technicians provide crime scene investigation services and are exposed to stressful violent crimes, motor vehicle accidents, biological or chemical hazards, and other appalling imagery. Forensic Technicians would likely experience physical and psychological stress after exposure to trauma, and security vulnerabilities similar to Sworn Police Officers. The perceived availability of mental health resources, job-related physical, psychological stress, and traumatic experiences of both Forensic Technicians and Sworn Police Officers from California law enforcement agencies were investigated using a self-reported survey. Responses were evaluated for any significant differences in the perceived stress, job-related physical stress, and resulting psychological impact affecting the participants. The survey contained a mix of True/False, Circle/Check the Appropriate Box, or Likert Scale (1–5) responses. The results were evaluated statistically and discussed. Results indicated Sworn Police Officers and Forensic Technicians have different on-duty stress levels, but similar off-duty stress levels. Nearly two-thirds of 54 job-related stressors were not significantly different between the two occupations. However, Forensic Technicians reported more adverse effects in 17 physical and psychological job-related activities compared with Sworn Police Officers. Forensic Technicians reported lower awareness levels and availability of agency mental health support services than were reported by Sworn Police Officers. This study reports for the first time an unexpected outcome that perceived and job-related psychological stress is greater for Forensic Technicians than Sworn Police Officers. Possible reasons for this disparity will be discussed as well as stress management tools that should be implemented to reduce health risk factors for both career professionals as well as increase public safety.     

The Causes and Consequences of Job-Related Stress among Prosecutors

Despite a growing body of literature documenting work stress among employees in various fields, there is a dearth of research that explicitly assesses the impact of different aspects of prosecutors’ working conditions on individual prosecutors and their organizations. Drawing on a sample of prosecutors in a southern state in the U.S., we first used OLS regression to examine which work-related stressors are important in predicting their levels of work stress, job satisfaction, and turnover intention. Using path analysis, we then explored the links between these stressors and a set of proposed mediating and outcome variables. We also conducted unstructured in-depth interviews with a subset of the sample to supplement and further illustrate the observed patterns. While job demands and organizational support play the most important roles in explaining the work stress of prosecutors, they do not have direct impact on the prosecutor’s commitment to the job. The roles played by psychological and emotional stressors are found to be negligible. Job-related stressors do not lead to turnover intention directly but indirectly through work stress and job satisfaction with a notable exception of the public/media stressor. This study provides a scientifically-based perspective regarding which working conditions should be addressed to maintain healthy and productive working environments among prosecutors.     

Evaluation of Operational Stress in Riot and Crowd Control Police Units: A Global Challenge for Prevention and Management of Police Task-Related Stress

The aim of the current study was to evaluate stress levels during routine activities and during a major political event by members of the VI Reparto Mobile, an Italian specialized police unit exclusively deployed for riot and crowd control, which had undergone serious stress and liability consequences after the 2001?G8-Summit in Genoa. The investigation protocol consisted of a psychological assessment at the beginning of the study, evaluation of task-related stress with the Job Content Questionnaire (JCQ) and the Effort-Reward Imbalance questionnaire (ERI) at two time periods, and evaluation of behavioral and clinical outcomes as measured by short-term sickness absences (STSA) throughout the duration of the study. The sample consisted of 290 policemen, representing a 98.6?% participation rate. Results found that unit officers were more emotionally stable, conscientious and open to experiences than the general male population and career soldiers. JCQ and ERI decreased significantly when compared with daily and special event activities (p?<?0.001). Fifty-one percent of officers took STSA during three months of routine deployment, whereas only 35.5?% took it during the 2009?G8-Summit. These results suggest that members of the specialized unit had good capacity to withstand stress. Chronic routine work might be significantly more stressful for these kinds of officers than assignment to a special high-risk political event when adequate training, positive psychosocial support and appropriate organization of the event are provided.

Identifying and Managing Stress in Child Pornography and Child Exploitation Investigators

In the last decade, law enforcement personnel have increasingly been tasked to police the internet in an effort to staunch the production and distribution of child pornography and to investigate computer-facilitated child exploitation. These investigative personnel have encountered a range of assignment-specific challenges and strains as a result of their involvement in this taxing and novel investigative activity. In some cases, the cumulative effects of these strains, together with repeated exposure to highly disturbing images of abused children, have resulted in stress reactions that have commanded the attention of police managers and police psychologists alike. The present article is intended to provide an overview of the stresses unique to child exploitation and pornography investigations, common reactions to these stressors, procedural safeguards to mitigate the impact of this high-risk assignment, and two model programs designed to meet the needs of the current generation of “cyber cops”.

Police Stress: A Structural Model

A number of existing studies have identified various factors that contribute to stress among police officers. This analysis is unique among these insofar as it employs structural equation modeling to specify, in path model format, the influence of participation in workplace decision-making and other variables on employee stress levels. The findings of this analysis provide new as well as confirmatory statistical evidence regarding the mitigating and direct effects of certain variables on physical stress. This study poses important implications by lending itself to meaningful future comparative research across occupations such as corrections and probation / parole.

Posttraumatic Stress Disorder and Comorbidity: Untangling the Gordian Knot

The high rates of psychiatric comorbidity for individuals with posttraumatic stress disorder (PTSD) have long been noted. The conceptual, clinical and aetiological relationships between PTSD and other disorders are so interwoven and multi-determined that understanding and treating posttraumatic psychopathology can feel like trying to untangle the legendary Gordian knot. This paper examines the varying streams of research seeking to better understand this extensive comorbidity. These streams of research include examination of the bi-directional relationships in the development of PTSD and key mood, anxiety and substance use disorders; the study of the shared manifest and common higher order features across these disorders and investigations of underlying biopsychosocial vulnerabilities. Finally, the paper examines the preliminary findings emerging using the new DSM-5 criteria for PTSD and queries whether these revised criteria will address the issue of comorbidity and assist in untangling the knot of posttraumatic comorbidity.     

Organizational and Human Factors Affecting Forensic Decision-Making: Workplace Stress and Feedback

Although forensic examiners operate in a stressful environment, there is a lack of understanding about workplace stress and feedback. These organizational and human factors can potentially impact forensic science judgments. In this study, 150 practicing forensic examiners from one laboratory were surveyed about their experiences of workplace stress, and the explicit and implicit feedback they receive. Forensic examiners reported that their high stress levels originated more from workplace-related factors (management and/or supervision, backlogs, and the pressure to do many cases) than from personal related factors (family, medical, and/or financial). The findings showed that a few (8%) of the forensic examiners sometimes felt strong implicit feedback about what conclusions were expected from them and that some (14%) also strongly felt that they were more appreciated when they helped to solve a case (e.g., by reaching a “match” as opposed to an “inconclusive” conclusion). Differences were found when comparing workplace stress and feedback levels across three core forensic science fields (forensic biology, chemistry, and latent prints) and across career stages (early, mid, and late). Gaining insights into the stress factors within a workplace and explicit and implicit feedback has implications for developing policies to improve the well-being, motivation, and performance of forensic examiners.     

Sexual Harassment and Posttraumatic Stress Disorder: Damages Beyond Prior Abuse

This study examined the extent to which harassment experiences correlate with posttraumatic stress disorder (PTSD) symptoms, and whether diagnosable PTSD on the basis of sexual harassment occurs after accounting for prior PTSD, prior sexual abuse, and prior psychological dysfunction. The sample consisted of a two-wave panel of 445 women who had received a domestic violence protective order from a Kentucky court. Hierarchical linear and logistic analyses confirmed that sexual harassment experiences were significantly correlated with PTSD symptoms after controlling for an extensive set of trauma variables measured in both the baseline and follow up interviews. Our findings lend further evidence that claims of PTSD from sexual harassment may be credible even if claimants have been victims of other forms of trauma.
