Stress exposure training

Last updated August 22, 2021

Stress exposure training is the practicing of important existing skills in a stressful and distracting environment to develop the ability to perform them reliably in spite of the circumstances.^[1]

There are a number of occupations where a potentially high-stress, high-risk environment can occur, where failure to act appropriately can lead to injury, death or significant loss. These settings can be found in military engagements, aviation, emergency medicine, mining, underwater diving, parachuting, bomb disposal, police work, and fire fighting. These environments impose a high demand on those who work in them, and there is a high potential for immediate and often catastrophic harm following an error. Emergency or crisis conditions can occur suddenly and without warning.^[1]

The effects of stress on the individual are a concern in industry, the military, aviation, sports, and other settings where effective performance under stress is required.^[1] In this context, stress is a process by which environmental demands result in a perception that demand exceeds resources. This can have negative physiological, psychological, behavioral, or social effects,^[1] by restricting attention and distracting the operator from the primary task.^[2] Technical skill is a necessary but not always a sufficient condition for effective performance in a stressful environment. Effective training to reduce the negative effects of stress on performance has become important in the training community. The purpose of stress exposure training is to prepare people to function effectively under high-stress conditions.^[1]

The main purpose of training is to develop and retain skills, knowledge, understanding and abilities, and most training is occurs in conditions which facilitate learning. These conditions usually involve an environment which is free of avoidable discomfort, surprises, and other distractions, allowing focused concentration on understanding and mastering the components and combinations of skills. This is generally effective when performance will be under similar circumstances, but when transferred to stressful operational conditions, reliable performance is not guaranteed.^[1]

The main purpose of stress training is to prepare the person to perform effectively in a high-stress environment. It increases familiarity with the environment and conditions in which the skills must be performed effectively, and develops the ability and confidence to perform those skills in spite of the distractions and task loading present.^[1]

Effects of stress on performance

Stress is recognised as adversely altering cognitive processes such as attention, memory, and making decisions. High task loads and time pressures tend to cause narrowing of attention and loss of team perspective. Noise, thermal stress, and fatigue have also been implicated in performance degradation. ^[3] Adverse environmental conditions can make effective performance physically more difficult at the same time that other distractions occur.

Theories of stress identify at least two aspects to human stress response. The appraisal process includes the person's assessment of a situation to decide whether they have the abilities and resources to cope, and has two stages:

Firstly, threat appraisal, and determining options for coping. The perception of the existence of a threat and an inability to cope or lack of options is the cause of stress.^[3]
Secondly, the self-regulatory mechanisms people use to control their emotions, thoughts, and behaviors in potentially threatening situations are important for directing efforts toward goal achievement in those situations. These factors help explain why some people manage to perform well under stress, while others fail to respond appropriately or make critical errors.^[3]

Strategies for managing stress-degraded performance

Three basic methods exist for counteracting the effects of stress on performance:^[3]

Exposure to stressors can be reduced by modifying the work environment or the stressor. This is a preferred strategy and is useful in many environments, but in some cases it is not possible or reasonably practicable to control the environment, and some stressors are inherently beyond control.
Training to improve the ability to cope in stressful situations. This is the goal of stress exposure training. It is the second line of defense.
Provision of care and support to those experiencing symptoms resulting from exposure to stress. This necessarily applies only to survivors and is an indication that the preferred options have failed.

Training objectives

Understanding of the stress environment: A lower level of stress will generally be experienced when a greater level of advance information on a stressful situation is made available. The subject is enabled to form more accurate expectations about the situation, increasing predictability and lowering surprise. The level of distraction is thereby reduced, and some planning is possible, which increases the avoidance of performance errors.^[1]
Skill development under benign conditions: There are a wide range of stress effects that can degrade task performance. Stress training may provide practice in behavioural and cognitive skills which allow better performance under stress, such as multi-tasking skills and prioritising critical activities.^[1]
Building confidence in the ability to perform under stress: The training is effective when a sense of mastery is achieved. Negative experiences will not have the desired effect.^[1]

Application of the techniques

Providing information: Information on stress and its likely effects is provided, and the value and goals of the training are explained, so that the learner can understand the purpose and develop a positive attitude towards the expected benefits. This also increases the sense of control and confidence, encourages realistic expectations and reduces the distractions of the stress environment, allowing more attention to task-relevant stimuli and anticipation of performance errors and what to do about them. This is generally most effective as the first phase.^[1]
Skill building: Specific cognitive and behavioral skills relevant to the management of the stressors are taught and practiced. The critical skills may be overlearned where this is appropriate.^[1] Overlearning increases knowledge and skill retention and can retain performance under stress, but may hinder ability to adapt to new situations. Overlearning should not be used when the trained response is only useful in a limited range of situations, or when one of several responses may be most appropriate, but it may be appropriate for situations where the same response is correct each time.^[3] The goal is to build skill sufficiently to maintain effective performance in the stress environment.^[1]
Practice under stress: The skills are applied and practiced under conditions of gradually increasing stress that are similar to those likely to be encountered in operational conditions. The full range of stressors should ideally be experienced in training, but exposure should be built up gradually, increasing the intensity or combinations after a successful demonstration of proficiency. A too sudden exposure to multiple stressors may hinder skill development.^[3] As skill in maintaining effective performance increases, the stressors are increased at a rate that allows successful performance to be maintained, and confidence in the ability to handle such conditions can grow.^[1] Learners should be aware of how realistic the stressors and combinations used in training are considered to be, so that expectations of operational conditions are realistic.^[3]

Stress-exposure training can be effective as a part of initial training or a part of refresher training, but should not be introduced before the skills are well learned or it can interfere with skill acquisition. If used in refresher training, it should follow an initial exercise and assessment of skills to ensure they are remembered and practiced correctly. It is not necessary or desirable to match the stress levels in the exercises with reality. A lower level of stress can be adequate to accustom the learner while less likely to cause a negative learning experience, but the simulations should be relevant and the situations reasonably realistic. A gradual buildup may have good results. Where stress training is optional or voluntary, a gradual buildup will allow learners to continue as far as they feel they are able to manage.^[1]

Experimental findings show that technical skill is a necessary but not always a sufficient condition for effective performance in a stressful environment, and that skills learned from stress training generalise to different tasks and stressors.^[1]

Familiarity with the stressors characteristic of the occupation is needed in order to reduce uncertainty and to improve effectiveness of learning.^[3]

Effectiveness

Analyses have indicated that the training is most effective with high- or normal anxiety individuals, and effectiveness is partly proportional to the number of training sessions. Four to seven sessions were needed to produce significant improvements in performance and anxiety levels. ^[3]

The training approach including all three stages has been shown to be most effective, with the skills training phase most important, and the training remains effective when unfamiliar stressors are applied. The training was also effective in preparing participants to perform tasks that had not been practiced under stress, and appears to be useful for people who may have to perform under unpredictable conditions.^[3]

Varieties

Stress inoculation training (SIT) – A clinically based system, with roots in clinical psychology, and the goal of building resistance to stress through cognitive and behavioral skill training and exposure to stressful stimuli. Trainees are exposed to sufficient stress to develop coping skills, but not so much that it overwhelms the person. These exposures and training allow the trainee to build up the ability to deal with stress, and the confidence necessary to function under greater levels of stress on the job. SIT focuses on the therapeutic input of a skilled practitioner, individualised treatment and reducing anxiety, depression and anger. It adds a fourth stage of review and analysing effectiveness of the training to that point.^[3] It was developed to reduce anxiety in doctors during times of intense stress by Donald Meichenbaum from 1985.^[4] It is used to help people with post traumatic stress disorder.^[5]
Practical applied stress training (PAST) – An application targeting police tactical enforcement teams, developed by Will Brink and detailed in a book published in 2010.^[6]

Stress management is a wide spectrum of techniques and psychotherapies aimed at controlling a person's level of stress, especially chronic stress, usually for the purpose of and for the motive of improving everyday functioning. Stress produces numerous physical and mental symptoms which vary according to each individual's situational factors. These can include a decline in physical health as well as depression. The process of stress management is named as one of the keys to a happy and successful life in modern society. Life often delivers numerous demands that can be difficult to handle, but stress management provides a number of ways to manage anxiety and maintain overall well-being.

Virtual reality therapy (VRT), also known as virtual reality immersion therapy (VRIT), simulation for therapy (SFT), virtual reality exposure therapy (VRET), and computerized CBT (CCBT), is the use of virtual reality technology for psychological or occupational therapy and in affecting virtual rehabilitation. Patients receiving virtual reality therapy navigate through digitally created environments and complete specially designed tasks often tailored to treat a specific ailment; and is designed to isolate the user from their surrounding sensory inputs and give the illusion of immersion inside a computer-generated, interactive virtual environment. This technology has a demonstrated clinical benefit as an adjunctive analgesic during burn wound dressing and other painful medical procedures. Technology can range from a simple PC and keyboard setup, to a modern virtual reality headset. It is widely used as an alternative form of exposure therapy, in which patients interact with harmless virtual representations of traumatic stimuli in order to reduce fear responses. It has proven to be especially effective at treating PTSD, and shows considerable promise in treating a variety of neurological and physical conditions. Virtual reality therapy has also been used to help stroke patients regain muscle control, to treat other disorders such as body dysmorphia, and to improve social skills in those diagnosed with autism.

Mathematical anxiety, also known as math phobia, is anxiety about one's ability to do mathematics. It is a phenomenon that is often considered when examining students' problems in mathematics.

Test anxiety is a combination of physiological over-arousal, tension and somatic symptoms, along with worry, dread, fear of failure, and catastrophizing, that occur before or during test situations. It is a physiological condition in which people experience extreme stress, anxiety, and discomfort during and/or before taking a test. This anxiety creates significant barriers to learning and performance. Research suggests that high levels of emotional distress have a direct correlation to reduced academic performance and higher overall student drop-out rates. Test anxiety can have broader consequences, negatively affecting a student's social, emotional and behavioural development, as well as their feelings about themselves and school.

Sport psychology is an interdisciplinary science that draws on knowledge from many related fields including biomechanics, physiology, kinesiology and psychology. It involves the study of how psychological factors affect performance and how participation in sport and exercise affect psychological and physical factors. Sport psychologists teach cognitive and behavioral strategies to athletes in order to improve their experience and performance in sports. In addition to instruction and training of psychological skills for performance improvement, applied sport psychology may include work with athletes, coaches, and parents regarding injury, rehabilitation, communication, team building, and career transitions. Also closely associated with Sports psychiatry.

The effects of stress on memory include interference with a person's capacity to encode memory and the ability to retrieve information. During times of stress, the body reacts by secreting stress hormones into the bloodstream. Stress can cause acute and chronic changes in certain brain areas which can cause long-term damage. Over-secretion of stress hormones most frequently impairs long-term delayed recall memory, but can enhance short-term, immediate recall memory. This enhancement is particularly relative in emotional memory. In particular, the hippocampus, prefrontal cortex and the amygdala are affected. One class of stress hormone responsible for negatively affecting long-term, delayed recall memory is the glucocorticoids (GCs), the most notable of which is cortisol. Glucocorticoids facilitate and impair the actions of stress in the brain memory process. Cortisol is a known biomarker for stress. Under normal circumstances, the hippocampus regulates the production of cortisol through negative feedback because it has many receptors that are sensitive to these stress hormones. However, an excess of cortisol can impair the ability of the hippocampus to both encode and recall memories. These stress hormones are also hindering the hippocampus from receiving enough energy by diverting glucose levels to surrounding muscles.

Human factors are the physical or cognitive properties of individuals, or social behavior which is specific to humans, and influence functioning of technological systems as well as human-environment equilibria. The safety of underwater diving operations can be improved by reducing the frequency of human error and the consequences when it does occur. Human error can be defined as an individual's deviation from acceptable or desirable practice which culminates in undesirable or unexpected results.

Dive safety is primarily a function of four factors: the environment, equipment, individual diver performance and dive team performance. The water is a harsh and alien environment which can impose severe physical and psychological stress on a diver. The remaining factors must be controlled and coordinated so the diver can overcome the stresses imposed by the underwater environment and work safely. Diving equipment is crucial because it provides life support to the diver, but the majority of dive accidents are caused by individual diver panic and an associated degradation of the individual diver's performance. - M.A. Blumenberg, 1996

Fitness to dive,, is the medical and physical suitability of a diver to function safely in the underwater environment using underwater diving equipment and procedures. Depending on the circumstances it may be established by a signed statement by the diver that he or she does not suffer from any of the listed disqualifying conditions and is able to manage the ordinary physical requirements of diving, to a detailed medical examination by a physician registered as a medical examiner of divers following a procedural checklist, and a legal document of fitness to dive issued by the medical examiner.

Stress in medical students is stress caused by strenuous medical programs, which may have physical and psychological effects on the well-being of medical students. Excessive stress in medical training predisposes students for difficulties in solving interpersonal conflicts as a result of previous stress. A significant percentage of medical students suffer from anxiety disorders because of the long term effects of stress on emotional and behavioral symptomatology. This condition has become a focus of concern nationally and globally, therefore the first line of detection and defense from stress are the students themselves. Students need to be given the tools to recognize and cope with stress, as well as being assured that they will not suffer judgment from others for recognizing their need for help in dealing with stress. The instructors, advisers and other faculty members who notice the signs of stress in a student need to approach the student in a non-threatening, non-judgmental way, in an effort to help medical students recognize and handle their stress.

Stress in the aviation industry is a common phenomenon composed of three sources: physiological stressors, psychological stressors, and environmental stressors. Professional pilots can experience stress in flight, on the ground during work-related activities, and during personal time because of the influence of their occupation. An airline pilot can be an extremely stressful job due to the workload, responsibilities and safety of the thousands of passengers they transport around the world. Chronic levels of stress can negatively impact one's health, job performance and cognitive functioning. Being exposed to stress does not always negatively influence humans because it can motivate people to improve and help them adapt to a new environment. Unfortunate accidents start to occur when a pilot is under excessive stress, as it dramatically affects his or her physical, emotional, and mental conditions. Stress "jeopardizes decision-making relevance and cognitive functioning" and it is a prominent cause of pilot error. Being a pilot is considered a unique job that requires managing high workloads and good psychological and physical health. Unlike the other professional jobs, pilots are considered to be highly affected by stress levels. One study states that 70% of surgeons agreed that stress and fatigue don't impact their performance level, while only 26% of pilots denied that stress influences their performance. Pilots themselves realize how powerful stress can be, and yet many accidents and incidents continues to occur and have occurred, such as Asiana Airlines Flight 214, American Airlines Flight 1420, and Polish Air Force Tu-154.

Diving safety is the aspect of underwater diving operations and activities concerned with the safety of the participants. The safety of underwater diving depends on four factors: the environment, the equipment, behaviour of the individual diver and performance of the dive team. The underwater environment can impose severe physical and psychological stress on a diver, and is mostly beyond the diver's control. Equipment is used to operate underwater for anything beyond very short periods, and the reliable function of some of the equipment is critical to even short term survival. Other equipment allows the diver to operate in relative comfort and efficiency. The performance of the individual diver depends on learned skills, many of which are not intuitive, and the performance of the team depends on competence, communication and common goals.

A diver training standard is a document issued by a certification, registration regulation or quality assurance agency, that describes the prerequisites for participation, the aim of the training programme, the specific minimum competences that a candidate must display to be assessed as competent, and the minimum required experience that must be recorded before the candidate can be registered or certified at a specific grade by the agency. A standard is a description of the quality required of a product, or a way of doing something that has usually been derived from the experience of experts in a specific field. The purpose is to provide a reliable method for people to share a reasonably consistent expectation regarding the scope and quality of the product or service. Training standards allow objective comparison between the training provided by various agencies and the competence indicated by certification or registration to the specific standard, though in most cases, training and competence may exceed the minimum requirement much of the time, and variation between newly certified divers can be considerable, partly due to differences in the training, and partly due to qualities of the candidate. Training standards may narrowly prescribe the training, or may concentrate on assessment of exit level competence, and allow recognition of prior learning based on various forms of evidence. To be useful, a training standard must be sufficiently specific to allow agreement on the requirements by most readers reasonably competent in the field, including the instructors, assessors, and learners who must use it, the employers of persons trained, the potential customers, and any quality assurance personnel who may need to enforce it. A training standard may be linked to a code of practice referring to how the training should be carried out.

Academic buoyancy is a type of resilience relating specifically to academic attainment. It is defined as 'the ability of students to successfully deal with academic setbacks and challenges that are ‘typical of the ordinary course of school life '. It is, therefore, related to traditional definitions of resilience but allows a narrower focus in order to target interventions more precisely. The academic buoyancy model was first proposed by psychologists Andrew Martin and Herbert W. Marsh, following the identification of significant differences between classic resilience and the day-to-day setbacks experienced by students.

Education in emergencies and conflict areas is the process of teaching and promoting quality education for children, youth, and adults in crisis-affected areas. Such emergency settings include: conflicts, pandemics and disasters caused by natural hazards. Strengthened education systems protects children and youth from attack, abuse, and exploitation, supports peace-building, and provides physical and psychological safety to children. In times of crisis, education helps build resilience and social cohesion across communities, and is fundamental to sustained recovery.
