Research suggests that police work is among the most stressful occupations in the world and officers typically suffer a variety of physiological, psychological, and behavioral effects and symptoms. Officers operating under severe or chronic stress are likely to be at greater risk of error, accidents, and overreactions that can compromise their performance, jeopardize public safety, and pose significant liability costs to the organization. Therefore, this study explored the nature and degree of physiological activation typically experienced of officers on the job and the impact of the Coherence Advantage resilience and performance enhancement training on a group of police officers from Santa Clara County, California. Areas assessed included vitality, emotional well-being, stress coping and interpersonal skills, work performance, workplace effectiveness and climate, family relationships, and physiological recalibration following acute stressors. Physiological measurements were obtained to determine the real-time cardiovascular impact of acutely stressful situations encountered in highly realistic simulated police calls used in police training and to identify officers at increased risk of future health challenges. The resilience-building training improved officers' capacity to recognize and self-regulate their responses to stressors in both work and personal contexts. Officers experienced reductions in stress, negative emotions, depression, and increased peacefulness and vitality as compared to a control group. Improvements in family relationships, more effective communication and cooperation within work teams, and enhanced work performance also were noted. Heart rate and blood pressure measurements taken during simulated police call scenarios showed that acutely stressful circumstances typically encountered on the job result in a tremendous degree of physiological activation, from which it takes a considerable amount of time to recover. Autonomic nervous system assessment based on heart rate variability (HRV) analysis of 24-hour electrocardiogram (ECG) recordings revealed that 11% of the officers were at higher risk for sudden cardiac death and other serious health challenges. This is more than twice the percentage typically found in the general population and is consistent with epidemiological data indicating that police officers have more than twice the average incidence of cardiovascular-related disease. The data suggest that training in resilience building and self-regulation skills could significantly benefit police organizations by improving judgment and decision making and decreasing the frequency of onthe-job driving accidents and the use of excessive force in high-stress situations. Potential outcomes include fewer citizens' complaints, fewer lawsuits, decreased organizational liabilities, and increased community safety. Finally, this study highlights the value of 24-hour HRV analysis as a useful screening tool to identify officers who are at increased risk, so that efforts can be made to reverse or prevent the onset of disease in these individuals.
研究表明,警察工作是世界上压力最大的职业之一,警察通常会遭受各种生理、心理和行为方面的影响及症状。在严重或长期压力下工作的警察犯错、出事故及过度反应的风险可能更高,这会影响他们的工作表现、危及公众安全,并给组织带来重大责任成本。因此,本研究探讨了警察在工作中通常经历的生理激活的性质和程度,以及连贯性优势恢复力和绩效提升训练对加利福尼亚州圣克拉拉县一组警察的影响。评估的领域包括活力、情绪健康、压力应对和人际交往能力、工作绩效、工作场所效率和氛围、家庭关系,以及急性应激源后的生理重新校准。获取生理测量数据,以确定在警察训练中高度逼真的模拟警察呼叫中遇到的急性应激情况对心血管的实时影响,并识别未来健康面临更高挑战风险的警察。恢复力培养训练提高了警察在工作和个人情境中识别和自我调节对压力源反应的能力。与对照组相比,警察的压力、负面情绪、抑郁有所减少,平和感与活力有所增强。还注意到家庭关系得到改善、工作团队内部沟通与合作更有效,以及工作绩效有所提高。在模拟警察呼叫场景中进行的心率和血压测量表明,工作中通常遇到的急性应激情况会导致极大程度的生理激活,需要相当长的时间才能恢复。基于24小时心电图(ECG)记录的心率变异性(HRV)分析进行的自主神经系统评估显示,11%的警察猝死和其他严重健康问题的风险较高。这比一般人群中的典型比例高出两倍多,并且与流行病学数据一致,表明警察心血管相关疾病的平均发病率是普通人的两倍多。数据表明,恢复力培养和自我调节技能训练可以通过改善判断力和决策能力、减少工作中驾驶事故的频率以及在高压力情况下过度使用武力,使警察组织显著受益。潜在结果包括市民投诉减少、诉讼减少、组织责任降低以及社区安全提高。最后,本研究强调了24小时HRV分析作为一种有用的筛查工具的价值,以识别风险增加的警察,从而能够努力扭转或预防这些人发病。
