Methods of measuring stress and their effectiveness

Methods of measuring centering and their lastingnessFirstly introduced by Hans Selye (1950), the term nervous strain is more apply to describe an individuals state of tension which is often seen as being related to modern bread and butter. However, tension assessment is made using different method which includes ego-importance reportBiomedicalPhysiologicalSelf report Life events (Holmes and Rahe 1976)The most common steering of assessing try is by self-importance-report questionnaires, in which individuals answer questions ab expose their rational or physical state. As a resoluteness, 2 medical doctors, Holmes and Rahe (1976) suggested that major conduct events, whether good or bad, were potentially striveful. Holmes and Rahe were the first to record the effect of life events in a systematic demeanor. By their study, they observed that patient ofs often experience several life events in the months before the onset of malady, and as a result, these life events seem ed to be associated with poor health and essay. They suggested that, stress is ca employ by change that hindquarters lead to greater susceptibility to physical and mental health disorders. They demonstrated the associations betwixt life events, stress and unhealthiness by developing close to method of measuring life events. Accordingly, they compiled the Social Readjustment Rating forbiddengo (SRRS) by examining 5000 patient records and making a list of 43 life events two positive and negative that seemed to precede illness . Approximately 400 participants were involved in the evaluation of each item in terms of the quantity of stress produced, out of which 500 was assigned to marriage as a reference point. The averaged results were then change integrity by 10 to get a measure of the individual events in terms of life change units (LCU).An example of Social Readjustment Rating Scale (SRRS)LIFE EVENTSRankLife EventStress Value1Death of a spouse1002Divorce733Marital separati on654Jail term635Death of a close family member636 ain imperfection or illness537Marriage508Fired at work479Marital propitiation4510Retirement4513Sex problematicies3923Son or daughter leaving2938 turn in sleeping habits1640Change in eating habits1541Vacation1342Christmas1243 minor(ip) violations of the lawlaw11ReferenceAdapted from Holmes, T., Rahe, R.

Journal of psychosomatic inquiry, 11, 213-218.Doctors, Holmes and Rahe (1967) findings suggested that the stress of life events is correlated with physical illness therefrom experiencing life events increases the chances of stress-related health breakdown. They were however criticised for being bias by investigating only Ameri deal men and using only correlational methods.Assessing the effectiveness of the Self report as a method of stress measurementThe SRRS provides the basis for perhaps the most active current bea of stress research and overly retrospective investigation usin g either the SRRS or SRE (Schedule of Recent Experience) have demonstrated a linear relationship amongst mounting life change, cardiac death, accidents, diabetes, leukaemia and infectious disease (Holmes Masuda, 1974).Using the research questionnaire, Holmes Rahe (1950) tested various sub-groups to see if the ratings were consistent, e.g. male and female, single and married and so on. As there was untouch suitable agreement between different groups, it seemed that the SRRS was a valid measure for all types of people regardless of their backgrounds. This contributes to the effectiveness of the self report method of stress measurement.This SRRS questionnaire (Holmes and Rahe, 1976) has served as a well-known as well asl for measuring the amount of stress star has experienced within the past category. Taking the test can help one see clearly if theyre at risk of illness due to stress.The method provided nigh of the first evidence that there is a genuine association between nerve -racking life events and physical illness.Also, the fact that physical health was assessed after life events increases the chances that life events were helping to spend a penny problems with physical health, rather than the new(prenominal) way roundThe Social Readjustment Rating Scale (SRRS) and the research associated with it represent a major breakthrough, this is because, it is now generally accepted that life events of various kinds can influence our psychological well-being and our physical and mental health.The development of the SRRS has made it easier to carry out research to test these ideas. This in turn has led to a cle arr understanding of the ways in which life events affect us.Indirect evidence that stressful life events play a role in life large(p) diseases was reported by Selye, Tache and Day (1979).According to these researchers, cancer was more common among adults who divorced, widowed or separated than among those who were married. The most likely explanation is that, those who were not married were punctuate because of lack of social support. It is however hard to establish causal relationships from such entropy (SSRS data). Perhaps those who were divorced or separated were more vulnerable to stress than those who were married hence, this stress vulnerability played a role in the collapse of their marriagesOne of the limitations to this method is that, it has often been assumed that almost any stern life can help to produce any type of illness. This has led to a relative ignoring of more circumstantial effects. Supporting evidence to this effect was where, two men, Finlay -Jones and Brown (1981) found that anxious patients were more likely than depressed patients to have experienced danger events(involving future threats), whereas depressed patients were more likely to have experienced loss events (involving past loses). More research into such studies will however be useful.Another negative side of the SRRS is that, a number of st udies have shown that peoples illness rates increase following increase rates in stress scores. However, a number of items on the scale ar vague e.g. personal injury or illness appears to suggest that someone could have the same stress score for flu and cancer. Second, there is no general failure to consider the cushion of an event on an individual. Christmas is considered to be a mildly stressful event, yet to some people, Christmas may seem extremely stressful, as it may emphasize their loneliness.The SRRS has impudence validity because many of the events listed are easily recognisable as stressful events. The values Allocated to each stress event have been carefully calculated from data provided by the opinions of many people. The survey form can be take ined out easily and quickly.With reference to Raphael et al. (1991), Self-report measures of life events are unreliable. A study had subjects fill out a scale regarding life events they experienced during the prior year. The subjects then filled out the same Questionnaire e very month for a year. Towards the end of the year the reports were quite different from the ones made at the beginning of the year (Raphael, et al. 1991). The questionnaire or scale also ignores chronic stresses such as money problems, general hassles etc. Taking this into account, the measure could be considered invalid.Biomedical Stress and ulcers (Brady 1958)One of the biomedical methods of measuring stress is the evidence that stress may be a causal factor in stomach ulcers. This research was first described by Joseph Brady (1958). Brady did classic studies linking high levels of stress to increased hormone production and the development of ulcers. Brady did this by placing monkeys in res genteelness chairs and conditioned them to press a lever. The monkeys were then given shocks every 20 seconds unless the lever was pressed during the same time. This experiment however came to an abrupt accommodate when unexpectedly many of t he monkeys died because of ulcers ca utilise by raised gastrointestinal hormone levels. The question put forward was whether the ulcers resulted from the electric shock or the stress. To enhance his results, Brady and his mates used yoked controls where one monkey called executive was liable for controlling the lever while a second monkey received the shocks but had no control oer the lever. Thus, only the executive monkey had the physiologic stress of having to press the lever, but both animals received shocks. after 23 days of 6 hours on and despatch schedule, the executive monkey died because of perforated ulcer. Brady initially thought that the stress might be related to the reinforcement schedule. He also tried several other routines such as 18 hours on and 6 hours off and tested the executive monkey to find out that stomach acidity was greatest during this period.After the experiment, Brady concluded that it was clearly stress, not the shocks that created the ulcers. Having s aid that, he also concluded that the greatest danger happened while the sympathetic arousal stopped and the stomach was make full with digestive hormones, which is a parasympathetic rebound linked with hypothalamic-pituitary-adrenocortical axis, hence HPA.Assessing the effectiveness of the biomedical as a method of stress measurementThe research carried out by Brady (1958) proved effectively that stress may be a causal factor in stomach ulcers. Stress often increases the secretion of hydrochloric acid, which plays in the development of some ulcers. Stress also weakens the defences of the gastrointestinal tract against this acid, thereby permitting gastric ulcers to develop. (Pinel, 1997).Supporting evidence to the effectiveness of Bradys experiment is Weiner et al. (1957) findings in support to Bradys experiment. Weiner et al. (1957) used army recruits to test for the effectiveness of Bradys experiment. Prior to rudimentary tuition, the soldiers were tested and classed on the ba sis of their release of digestive enzymes as over-secretors or under -secretors. After quartette months of stressful training, 14% of the over-secretors had developed ulcers, whereas none of the under-secretors had. This suggests not only that the same principles apply to humans, but also that individual differences may be primal in view of the fact that not all of the over-secretors developed ulcers.Biochemical method of measuring stress involves adrenaline and noradrenalin hormones. These hormones provides effective measures of stressThe research also suggested that too very much stress at work can lead to development of ulcers.Bradys experiment was however criticised for not randomly selecting the monkeys and also, using non-human samplesSubsequent research has also demonstrated that ulcers are not always stress related, there could be an underlying biological cause. E.g. fungiBradys experiment is associated with the Hypothalamic -Pituitary-Adrenocortical Axis, this in effect e levates levels of glucose and some hormones including the ACTH (Acetylcholine) and the body continues to use its resources at an accelerating rate.Stress-triggered increases in heart rate and rent pressure. This may result in the deterioration and blocking of blood vessels thereby increasing cardiovascular disorders and chronic stress.Many physical, organisational and social factors in the work come on can become sources of stress, usually exerting a relatively long-term, stable and chronic influence. roleplay overload, lack of control, and poor interpersonal relations at work may all lead distress, ill health and eventual burnout. Hence, biomedical serves as a suitable method for assessing stress at a work placePhysiological BiofeedbackPhysiological measures in stress provide indications of the level of sympathetic nauseous arousal. This can include a persons heart rate, blood pressure, and respiration rate and so on. One of the common physiological methods used in measuring s tress is biofeedback.Biofeedback is a technique which involves recording the application of the physiological systems of the bodys stress response, that is the heart rate, blood pressure or tension in the neck muscles. This enables the individual to monitor their own physiological arousal in real times and develop control over it (Gatchel, 1997). During the process, the individual is attached is attached to a machine which produces feedback most some physiological activity such as an auditory or visual signal to indicate whether his / her heart rate is too high or moderate. The individual is also happy in techniques to reduce physiological aspects of stress such as relaxation training. One of the common ways humans can learn to control their top dog-waves is by using electroencephalogram ( encephalogram) biofeedback.Electroencephalogram (EEG)An EEG involves placing electrodes on a persons scalp to record the small changes in electrical activity of the brain. These changes are d isplayed on a computer screen. EEGs are often used to measure changes in brain activity during the different stages of sleep however, in biofeedback EEG is used to give visual feedback of the activity of the waking brain. Biofeedback training however involves three stages, they includeDeveloping an awareness of the particular physiological response such as the heart rateLearning ways of controlling that physiological response in quiet conditions. This can include providing rewards for successful control in addition to no feedbackTransferring that control into the conditions of everyday life.Assessing the effectiveness of biofeedback as a method of measuring stressThis method has been effective in significant long-term reductions in stress in everyday life and has also led to benefits by producing a consciousness of control rather than purely psychological methods. Attanasio et al (1985) researched and found that biofeedback helped teenagers and children with stress related disorder s to gain control over the symptoms of migraine headaches. The coming was however criticised that it treated symptoms rather than underlying conditions.Biofeedback has enjoyed a brief soar of popularity since its inception in the late 1960s. It has successfully treated many medical problems, particularly stress related illnesses such as incontinence, anxiety, hypertension, circulatory problems, irritable catgut syndrome and so on.Since its inception, it has produced significant long term reductions in stress in everyday life without any side effects unlike the other physiological approach (drugs)Biofeedback may lead to benefits by producing a sense of control rather than purely psychological methods. It is however not invasive, but rather voluntary.Arguably, the benefits of biofeedback could be gained from another relaxation technique and so biofeedback is an unnecessary expense. This serves as a limitation to biofeedback as a method of measuring stress.Recommendation of one way o f stress measurement for use by the companyAbove all these methods of measuring stress, I will recommend life events which falls under self report because it is by this way that the individual can fully express his/her lookingings and pain through subjective questionnaire about their mental and physical state.Criteria 3.1Physiological approach to stress management and controlStress control and management is the attempt that is made to cope with stress through reduction of the of the stress response. there are many approaches to trim back a persons stress levels, but usually, it is aimed at the physiological and psychological effects of stress. The basic target for stress management is usually base on changing the individuals perception of the stressor.Physiological approaches to stress management are techniques that try to control the bodys response to stress by reducing physiological activity. The physiological components of stress can include physiological arousal, sleep dist urbance, fatigue, gastrointestinal disturbances, headaches, concentration problems, increased rule of irritability and anger, agitation, increased likelihood for illness, and reduced productivity. The impact and the expression of these stress symptoms vary with the individual and the stressful event. Two physiological methods for controlling stress include biofeedback and stress. However, I am going to evaluate one out these two, which is Anti-anxiety drugs technique.Anti-anxiety drugsAnti-anxiety drugs are medicines that are used calming and relaxing grueling stress cases. They can also be used to calm nervousness, tension or for specific phobia disorder. The human body produces chemicals such as hormones and neurotransmitters that create anxiety, which can be countered using other chemical substances such as drugs that reduce anxiety. There are different types of anti- anxiety that work through different mechanisms. The most common drugs areBeta-blockersBenzodiazepinesAlcohol (r arely used)Beta-blockersBeta-blockers are one of the drugs used control stress by reducing activity in the sympathetic nervous system. They have a direct action on the heart and circulatory system hence they decrease the heart rate and lower peripheral blood pressure. Their effects are on the body however, they do not have direct effects on brain activity. Lau et al. (1992) considered the findings from numerous studies in a meta-analysis hence combining data from several studies. Thus, beta-blockers have proved useful in reducing blood pressure and in treating patients with heart disease. Psychological research also concludes that, the drug reduced the risk of death by about 20% in patients pitiable from heart disease. It also enhances performance in musicians and public speakers (Taylor 1995). However, one disadvantage of beta-blockers is that, they target symptoms rather than causes of anxiety and stress hence providing only temporary improvement.Benzodiazepinessometimes when dru gs are taken, they elapse in natural processes by controlling the action of neurotransmitters. Types of benzodiazepines include Valium and Librium which are used for increasing the neurotransmitter GABA, which decreases serotonin activity, which at last reduces arousal. Benzodiazepines are very effective and used worldwide by approximately hundred million people. Despite its effectiveness, benzodiazepines have got some side effects which are linked to low levels of serotonin. Common effects can include drowsiness, causing of cognitive and memory impairments, feelings of depression, and interacting unpredictably with alcohol Ashton (1997). Another effect of the drug is that, it is more likely to be involved with accident.Strengths of Anti-anxiety drugsAnti-anxiety drugs can be very effective in controlling severe feelings of stress. Beta blockers for instance act on the involuntary nervous system to reduce heart rate/blood pressure physiological stress arousal.Anti-depressant drugs , less often used, can be take into account for severe anxietyBenzodiazepines such as Valium increase the activity of the inhibitory neurotransmitter GABA in the brain.Anti-anxiety drugs decrease arousal and relax the body by reducing tension in the muscles. Since stress response involves high arousal, tranquillizers may in some cases reduce stress flunkes of Anti-anxiety drugsAnti-anxiety drugs like benzodiazepines work by reducing brain activity. While this temporarily relieves anxiety, it can also lead to unwanted side effects.The higher the dose, the more pronounced these side effects typically are. But some people feel sleepy, foggy, and uncoordinated even on low doses of benzodiazepines, which can cause problems with work, school, or everyday activities such as driving. Some even feel a medication hangover the next day.Because benzodiazepines are metabolized slowly, the medication can build up in the body when used over longer periods of time. The result is over sedation. Peo ple who are over sedated may look like theyre drunk.Anxyolitic drugs can cause psychological and physical dependence, tolerance and addiction.Psychological approach to stress management and controlPsychological approach to stress control and management are the techniques that try to control the cognitive, social, and emotional responses to stress. They do this by addressing the underlying cause of stress such as faulty thinking. This approach works by changing the persons perception of the stressor and increasing their perception control. One psychological approach to stress control and management is the cognitive-behavioral therapy.Cognitive-behavioral therapyCognitive-behavioral therapy to controlling stress is based on the cognitive appraisal definition of stress and aims to change a persons perceptions and thoughts relating to, and dealing with stressful disorders. This therapy is appropriate for dealing with stress hence the assumption behind the cognitive approach is that, it is the way one thinks about the problem that is maladaptive. Thus, if an individual can be trained to reorganize their thinking and self-beliefs, the underlying problem itself may simply disappear. This approach to managing stress involves stress inoculation training and hardiness training.Stress inoculation trainingStress inoculation training (SIT) Unlike many cognitive therapies, stress inoculation training (SIT) is a more problem-focused coping strategy. It was developed by Donald Meichenbaum (1977, 1985) and the basic idea was to prepare individuals to cope with potential stressors. According to Meichenbaum (1985), the best way to cope with stressors is to go on the offensive and try to pre-empt them. People should try to name sources of stress and have effective coping strategies ready to put in place. Meichenbaum (1985) describes SIT asAnalogous to the concept of medical inoculation against infectious diseases It is intentional to build psychological antibodies or coping ski lls, and to enhance resistance through exposure to stimuli that are strong enough to arouse defences without being so sinewy as to overcome them. (Meichenbaum 1985)There are three main phases in stress inoculation training1. Assessment with this training, the therapists discuss the nature of the problem with the individual, and gazump the individuals perception of how to eliminate it. Meichenbaum (1985) considers this relationship to be very important as it provides the glue that allows the various aspects of the therapy to work together.2. Stress reduction techniques the individual learns various techniques for reducing stress, such as relaxation and self instructional training, communication, assertion, problem solving, anger control, parenting, study skills and using social support by using coping self statements.3. Application and follow through In this final phase, the individual imagines using the stress reduction techniques learned in the second phase in difficult situation s and engages in role play of such situations with the therapists, before using the techniques in a real life situations.Strengths of stress inoculation trainingOne important strength of Stress Inoculation Training (SIT) is that, it is very flexible. This is because, it consists of a wide variety of cognitive and behavioural techniques tailored to the individual needs of the client, which can be used to deal with many types of stressor (e.g., time-limited/persistent, controllable/uncontrollable, predictable/unpredictable, current/in the past).It has been found to be successful in helping people deal with the stress of chronic pain, performance anxiety, specific phobias and work related stress (Meichenbaum, 1977, 1985). This training has also helped athletes deal with the stress of competition (Mace, Eastmen Carroll, 1986) and helping patients prepare for surgery (Langer, Janis Wolfer, 1975).Weakness of stress inoculation trainingStress inoculation training is however of less value when treating individuals who are highly stressed or exposed to very stressful situations. Most individuals differ in how easy they find it to use coping self statements in stressful situations.Hardiness trainingOver these years, much research into stress has shown that there are significant individual differences in the way that people respond to stress. Since some individuals seem to cope better than others do, it makes sense to try to isolate the reasons why they can do so. The hope is that more effective ways of coping can be passed on to help those who are not as well prepared. Suzanne Kobasa (1986) has identified such individuals, who she describes as hardy, as those whose cognitive strategies are better suited to dealing with stress. For example, they are more able to identify the symptoms of stress hence avoiding action can be taken in time. They make more realistic assessments of stressors, including being aware of the positive aspects of stressful situations, opportunitie s and new challenges. Kobasa suggests that hardiness can be improved with appropriate training. Her programme consists of three techniques1. Focusing This explains that one should focus on the physical signs of stress and bear in mind when further attention is needed.2. Reconstructing stress situations This technique the individual to think about recent stressful situations and note how it might have turned out both better and worse, hence becoming aware that things could have been worse enables you to feel more positive.3. Compensation through self-improvement If an individual is affected by a stressor that cannot be changed or avoided, then it may be helpful to take on another challenge that can be mastered. Consequently, this assures you that you can hope.Strengths of hardiness trainingThere is little direct research evidence on the effectiveness of hardiness training and what research there is, however, Fischman taught a small number of executives these strategies and they had greater job satisfaction, fewer headaches, and better sleep patternsWeaknesses of hardiness trainingReports were made that people who have followed this kind of programme do score higher on a test of hardiness, report feeling less stressed, and have lower blood pressure than before, Sarafino (1990).The study was done on a small scale and there was no follow-up, so results may have been due to increased attention and communication onlySummaryBoth Meichenbaum (1985) and Kobasas(1986) approaches to stress management place great emphasis on the individual gaining control of a stressful situation because it is more often the sensation of being out of control that takes a situation beyond a persons ability to cope.
