Journal of Occupational Health J Occup Health 2003; 45: 1–7 Review Stress Management and Workplace Disability in the US, Europe and Japan Deborah L. JONES1, Takeshi TANIGAWA2 and Stephen M. WEISS3 1 Department of Psychology, Barry University, USA, 2Institute of Community Medicine, University of Tsukuba, Japan and 3Department of Psychiatry and Behavioral Sciences, University of Miami School of Medicine, USA Abstract: Stress Management and Workplace Disability in the US, Europe and Japan: Deborah L. J ONES, et al. Department of Psychology, Barry University, USA—Although the health care costs and the number of disability cases across all medical illnesses have increased, disability management programs implementing stress management interventions have been found to improve physical and mental health, reduce costs to employers, and facilitate the reintegration of injured individuals into the work environment. Stress management programs limit the impact and chronicity of disabilities and can be used to reduce and control the cost of disability in the workplace. Providing the most efficacious behavioral interventions thereby allows employers, employees and health professionals to work cooperatively to achieve optimum health and cost effectiveness. This review presents a variety of group and individual interventions, which have been utilized to aid disabled employees in coping with work-related injuries and medical illness. The implementation of stress management interventions in the workplace is described in detail, with special emphasis on the use of cognitive behavioral stress management. Finally, this review outlines a team approach to the application of a workplace stress management intervention aimed at reducing the overall impact of disability. (J Occup Health 2003; 45: 1–7) Key words: Stress reduction, Cognitive behavioral stress management, Intervention study, Disability, Workplace Stress Management is a psychoeducational program for dealing with stress in which individuals are taught to become aware of their appraisal of stressful events (positive, negative, surmountable, impossible) and to Received Jan 24, 2002; Accepted Oct 9, 2002 Correspondence to: T. Tanigawa, Institute of Community Medicine, University of Tsukuba, 1–1–1 Tennodai Tsukuba-shi, Ibaraki 3058575, Japan develop methods for more effective coping (e.g., managing problems efficiently and with less stress1)). Stress management interventions utilize a variety of techniques, including self-management skills, relaxation training, biofeedback, behavior modification, cognitive behavioral therapy, social support, emotional expression, and physical activity, such as exercise and yoga2). Group and individual stress management interventions are designed to improve coping skills, increase selfconfidence and reduce vulnerability to distress. Stress management is also an integral component of health promotion in the workplace3) and is an element of many workplace disability programs. Interventions implemented early in the course of disability have been found to greatly reduce the amount of time needed away from work4–6) and to reduce the potential for chronicity7, 8). Stress management programs limit the impact of disabilities and can be used to reduce and control the cost of disability in the workplace. Workplace stress management programs for individuals with disabilities include patient education and support groups that focus on improving quality of life (e.g., fewer symptoms, better functioning, less pain) and reducing the adverse effects of medical treatment (e.g., less pain from procedures, side effects of medication, anxiety). Stress management interventions have been developed for a variety of disorders, including musculoskeletal injuries and disorders (back pain 7, 9) , neuromuscular disorders (multiple sclerosis10)), immune system disorders (HIV11)), chronic fatigue syndrome12, 13), arthritis14, 15)), high blood p r e s s u r e 16), h e a d a c h e 17) a n d m i g r a i n e 4–18) a n d psychological distress19). Cognitive behavioral stress management (CBSM) interventions combine stress management techniques with cognitive strategies. The cognitive behavioral component was developed to teach individuals various forms of active coping strategies (e.g. cognitive restructuring including re-framing, thought replacement and challenging irrational thoughts, relaxation techniques, and 2 assertiveness training). Generally, coping strategies categorized as active-behavioral strategies (e.g., planning, seeking social support) or active-cognitive strategies (finding meaning in an illness, cognitive re-framing) are associated with a more positive affect and higher selfesteem in various populations dealing with chronic illness20–23). Conversely, denial and avoidance coping strategies (denying the illness, avoiding situations, persons or medical treatment that are related to the illness or disability) are associated with greater depression and distress25–27). Cognitive behavioral self-management interventions have been shown to be effective means of managing several types of illness including HIV/AIDS24, 28), chronic pain29), migraine18), chronic fatigue syndrome13) and carpal tunnel syndrome30). Cognitive-behavioral interventions have been used with to a) decrease depression and anxiety b) increase social support and c) teach more effective coping and stress-reduction strategies 32). Cognitive behavioral skill training has been demonstrated to improve health status, reduce substance abuse behavior, and improve quality of life11, 31, 32). In addition, unlike more cognitively complex models, e.g., psychodynamic therapy, cognitive behavioral skills are also more rapidly understood and integrated by patients at a variety of levels of intellectual and educational attainment. Application of the Stress Management Intervention to Workplace Disability. Stress management workplace interventions designed to meet the needs of those with disabilities focus on selfmanagement of illness and injury. Most self-management programs include stress management, pain and illness management and exercise and nutrition plans. Stress management programs include three successive components, typically taught over a 6 to 10 wk period. Participants are first taught to identify stress and stressors (education phase). Next, participants learn cognitive skills aimed at improving coping with stress (skills acquisition phase). Finally, participants practice stress management techniques in targeted situations while monitoring their effectiveness (practice phase33)). Education Phase The first phase of stress management for disability group intervention emphasizes social support; participants meet with other individuals having disabilities similar to their own. Social support obtained from participating in psychological interventions has demonstrated improved outcome in disabled populations (cancer34)). Participants learn that stress can negatively affect the progression of their illness or disability and its eventual clinical outcome by causing psychological and biochemical changes (e.g., immune suppression, decreased depression11, 33)). Patient education and social support have been J Occup Health, Vol. 45, 2003 demonstrated to provide health and cost benefits in dealing with minor and acute illnesses, psychosomatic and stress-related disorders, chronic pain, diabetes, a s t h m a , a r t h r i t i s , s u r g e r y a n d c h i l d b i r t h 35). Psychoeducational interventions have been developed to treat patients throughout the lifespan presenting with arthritis 14, 15, 36, 37) , cancer 38–41) , chronic illness 31) , hypertension22), chronic fatigue13, 42), chronic pain31, 43, 44) and back injury5). Cognitive behavioral education component. Cognitive behavioral strategies are taught that will provide the employee with such skills as cognitive re-framing, problem- and emotion-focused coping, assertiveness and anger management and promote attitude change45, 46). Cognitive re-framing, examining thoughts, opinions or beliefs from a different perspective, enables the patient to challenge existing ideas that may be generating negative emotions (e.g., living with a disability “one day at a time” rather than “for the rest of my life,” developing a revised view of the self as a productive member of the workforce). Skills Acquisition Phase In the skills acquisition phase, participants are taught to observe their behavior and record the most stressful situations, while noting physical, emotional and behavioral reactions to stressors. They are also encouraged to record their maladaptive responses to stressors (e.g., increased smoking and substance use, decreased sleep and exercise47)) in a stress diary. In this phase, participants are taught to examine the role of their disability as a stressor. In addition, they note the antecedents of their reactions to stressors, focusing on events occurring immediately prior to feelings of stress (e.g., feelings of anxiety may be preceded by doctor visits). Group discussion focuses on negative internal monologues about the disability that may lead to irrational feelings when faced with disability-related stressors, and the contribution negative monologues may make to feelings of stress (e.g., “I can’t do anything anymore; I’ll never be able to function normally again” may lead to feelings of depression or hopelessness48). Skills acquired may consist of cognitive behavioral self-management techniques, time management skills and behavioral regulation strategies, including relaxation training and nutrition and exercise plans. Cognitive behavioral skills. Participants are taught to apply problem-solving skills that are appropriate to the problem situation (e.g., applying problem-focused coping skills to problems that can be solved by personal action and applying emotion-focused coping skills to problems that must be emotionally tolerated because they have no potential solution.) Assertiveness training is used to teach Deborah L. JONES, et al.: Stress Management and Workplace Disability employees to stand up for their rights by learning to express their thoughts, feelings and opinions without infringing on the rights of others. Assertiveness training for the workplace relies on developing communication skills such as saying “no” or using “I statements”, responding to others’ specific behavior in terms of its impact on the individual’s emotions, e.g., “I feel disrespected when you criticize my physical limitations.” Finally, anger management focuses on applying cognitive behavioral skills to enable the individual to recognize situations that trigger anger and engage in more constructive expressions of anger, such as using “I statements”, e.g., “I was angry when my contribution was not acknowledged.” Relaxation Training. Relaxation training is a behavioral self-management skill designed to affect the physiological experience of stress by reducing physiological arousal (the stress response) and increasing the parasympathetic (calming) response48, 49). Examples of relaxation training include progressive muscle relaxation, guided imagery, meditation or meditative relaxation, yoga and hypnosis. Progressive muscle relaxation (PMR 49)) teaches participants to recognize feelings of tension and relaxation by having them tense and then relax muscle groups throughout the body. PMR may be combined with diaphragmatic breathing exercises to deepen the feelings of relaxation, and is used selectively with disability patients having chronic pain or muscle or tissue injury. Meditative relaxation50) combines muscle relaxation with quiet surroundings, a comfortable body position, a repetitive sound (such as “Om” or “peace”) and a passive attitude. Participants sit with muscles relaxed and focus their attention on each breath while repeating their sound. Attention to the sound maintains muscle relaxation. Participants with pain-related disabilities often have difficulty in a seated posture, and may also complete this exercise in a reclining position. A similar method, mindfulness meditation51), was derived from Buddhist meditation practice, and incorporates mindful awareness of thoughts and sensations arising while focusing on the breath or a sound. Participants are encouraged to simply become aware of their thoughts regarding their pain or disability without judging the content, enabling them to become aware of their response to their perceptions. This technique has been used effectively in the self-regulation of pain52) and was found to be more effective than physical therapy, medication and antidepressants, resulting in decreased use of medication and increased physical activity. Finally, guided imagery, similar to meditative relaxation, teaches participants to replace periods of pain or distress with peaceful images such as the rhythmic movement of the ocean. Once patients have learned to relax, they are instructed to practice independently at home. The concept 3 of homework is integral to stress management, as it allows the participant to master concepts learned during group or individual sessions. Practice Phase The final phase of stress management, practice, facilitates the application of problem-solving techniques to stressful situations as they arise, encouraging participants to assess the efficacy of the techniques and revise their goals as needed. Cognitive self-management techniques utilized may include positive re-framing, goal setting and behavior modification. Participants are encouraged to complete behavioral homework assignments and may establish contingency contracts to facilitate behavior modification. The goal of behavior modification is to shape behavior, rather than to remove feelings of pain or discomfort53). Behavior is modified by identifying pain reinforcers, stimuli that increase the likelihood that pain behavior will be repeated. This final phase of stress management is designed to inoculate the individual from disability-related stress54). Cognitive behavioral practice. Employees are encouraged to apply skills learned in sessions to present situations in the workplace, home or social interactions. For example, an employee experiencing chronic back pain might learn a problem-focused strategy, such as asking for assistance with lifting, and an emotion-focused strategy, such as emotional acceptance of physical limitations. Assertiveness training skills are applied to employee defined problem situations, allowing employees to return to group and discuss outcomes. Additional consideration is given to employees presenting with issues such as domestic violence, which may require special intervention or concerns regarding assertiveness in the home. Stress Management in the Workplace: Application and Effectiveness Worksite disability management can include prevention, wellness and safety programs, employee assistance programs (EAP) and return to work programs. Ideally, such programs are designed to instill a sense of teamwork and to provide measurable outcomes. Psychologists play a key role in the development of disability management interventions, which are frequently multidisciplinary and comprise various components. These psychological interventions may range from informational and psycho-educational wellness and safety programs (e.g., stress management) to more sophisticated programs including individual directive (behavioral, cognitive and cognitive behavioral) and non-directive (supportive or dynamic) therapies. The utilization of psychologists in disability management plays an additional role in the prevention 4 of work-related disability through a proactive strategy that focuses on early identification of environmental (workplace), social, psychological and physiological factors that may lead to eventual disability. The combination of psychological and medical care techniques can improve outcomes in disability management and assist businesses in remaining competitive so that reducing medical expenses and time off the job offset the cost of behavioral interventions such as stress management55). The integration of psychologists into the workplace through disability management programs can assist both the employee and employer. Psychologists can aid injured/disabled employees in adjusting to their ailment, and assist employers through the provision of education and information. Psychologists can also provide psychoeducational training services to management and staff on topics such as stress management and disability-related matters. Through the collaboration of psychologists, employees, and employers, stress management programs can facilitate improved physical and mental health in a cost-effective manner. There is considerable evidence that worksite stress management programs are cost effective. For example, stress reduction interventions reduce the effects generated by stress (e.g., hypertension, increased endocrine levels, immune suppression, increased susceptibility to illness), and the behavioral changes that affect physiology, (e.g., increased smoking and substance use, decreased sleep and exercise47)). Large-scale studies have demonstrated disability cost reductions based on decreased medical utilization55, 56) and reduced absenteeism57). A review of stress management interventions in the workplace found the most positive results across the various health outcomes were obtained with a combination of two or more techniques. Nevertheless, the great variety of stressmanagement techniques in combination with the wide range of health outcome measures used in stress intervention studies prevents specific conclusions about the efficacy of each technique and each outcome. Stress management in the workplace is effective in enhancing health, but the choice of which technique is appropriate must be based on the specific disability and health outcome targeted for change60). Stress management for disabilities in the workplace is a psychological intervention aimed at reducing the human, social and economic cost of disability to workers, employers and society. Early psychological interventions improve disease prognosis and overall functioning 4). Similarly, psychological/educational interventions for back pain9) and lower back pain have found continued activities7) and a combination of clinical and occupational interventions6) to result in a faster return to work, less chronic disability and fewer recurrent problems7–9). The cost effectiveness of stress management techniques has J Occup Health, Vol. 45, 2003 been illustrated with a variety of disabilities. 1. Decreases in clinic visits (36%) and in anxiety, hostility and depression were obtained with group behavioral interventions aimed at the control of chronic pain. The intervention consisted of 10 × 90 min weekly group meeting (physiology of pain, medical and behavioral treatments relaxation, yoga, communication skills, goal setting, problem solving, cognitive restructuring and homework exercises) 35). 2. Decreases in the length of hospital stay for surgical patients (1.5–2 d) were obtained with an intervention aimed at providing 1) health care information, 2) skill building exercises including relaxation and 3) psychosocial support building35). 3. Patients with psychosomatic symptoms comprise approximately 60% of visits to medical practitioners in the US. Improved health outcomes were obtained from a mind-body intervention on behavioral change vs. an information only condition, resulting in decreases in medical office visits over 6 months. The intervention consisted of educational materials, relaxation-response training, awareness training, and cognitive restructuring, 90 min × 6 wk35). 4. Thirteen to fourteen million individuals in the US have a history of coronary artery disease; 1.5 million individuals each year experience a myocardial infarction, of whom one-third die, half of whom do so within 60 min of the event. The total cost of cardiovascular disease was $18 billion in 1994. Cognitive behavioral stress management interventions targeting “Type A” high stress individuals have been used to decrease the risk of myocardial infarction (MI). In addition, nutrition and fitness interventions are often d e s i g n e d t o t a rg e t p o t e n t i a l l y d e b i l i t a t i n g atherosclerotic vascular disease35) Workplace disability management teams (e.g., physicians, nurses, psychologists, occupational therapists, social workers, physical therapists) represent a taskforce within the workplace devoted to prevention, wellness19) and safety programs and return to work programs, as well as rehabilitative care58). Team members are integral to the implementation of stress management interventions for workplace disability. Team members can utilize cognitive behavioral stress management interventions to enhance worker productivity and satisfaction by developing group and individual interventions. In addition, team members can support injured and disabled employees during adjustment to their disability, and facilitate employer-employee relations by providing education and training services to management and staff on disability-related matters. Examples include: 1) training workplace managers as well as general staff members regarding disabilities and their occurrence in the workplace to enhance comfort in addressing health Deborah L. JONES, et al.: Stress Management and Workplace Disability issues actively and proactively59), 2) training to facilitate the development and maintenance of a supportive atmosphere for recovery, and 3) training on reintegration of the disabled employee in the workplace. Smaller companies may lack the resources necessary to establish a disability management team, and may establish alternative external resources for providing health care services, including referrals to outside agencies or community health centers. Many companies offer counseling services; of employers surveyed, 32% of small businesses (under 100 employees), 54% of medium sized businesses (100–500 employees) and 71% of large businesses (over 500 employees) offered counseling61). In addition, a variety of publications and audiovisual materials are available for large and small businesses seeking to develop and implement health care stress management interventions62, 63). Finally, Employee Assistance Programs (EAPs), on- and off-site as well as on line, offer stress management programs 64, 65). In addition, community health centers offer stress management programs for a variety of disabilities. The importance of stress management programs and their integration in the workplace has become an international issue35, 62, 63, 65–69). Although the health care costs and the number of disability cases across all medical illnesses have increased, disability management programs implementing multidisciplinary interventions including stress management have been shown to improve physical and mental health, reduce costs to employers, and facilitate the reintegration of injured individuals into the work environment. Group and individual interventions have been effectively utilized to aid disabled employees in coping with work-related injuries and medical illness. Multidisciplinary interventions, primary, secondary and tertiary prevention programs and interventions for specific populations provide a comprehensive and effective approach to disability management. Future interventions should be designed within a theoretical model, targeting the workplace environment by addressing individual and organizational factors, increasing worker involvement, assessing stressors and evaluating health and cost efficacy measures60, 70) In addition, interventions should respond to culture, gender and job type-specific issues that may moderate workplace stress 71–75). Providing the most efficacious stress management interventions ultimately allows employers, employees and health professionals to work cooperatively to achieve optimum health and cost effectiveness. 3) 4) 5) 6) 7) 8) 9) 10) 11) 12) 13) 14) 15) 16) 17) References Taylor SE.
