Circulatory and central nervous system responses to different types of mental stress
The purpose of this study was to compare the physiological responses to different types of mental stress encountered in the workplace. Circulatory and central nervous system responses were examined in eight healthy males by exposing them to 20-min of white noise (80 dB(A)) and 20-min of computer-based mental arithmetic tasks as models of vascular and cardiac stress, respectively. The results indicated that both cardiac and vascular stresses increased blood pressure and showed a cumulative effect as exposure period was extended. Heart rate and prefrontal oxygenated hemoglobin levels increased in the face of cardiac stress but were not clearly altered by vascular stress and indicated that cardiac stress higher cardiac response and requires more oxygen supply to the brain. The circulatory and central nervous system responses to cardiac stress and to vascular stress may have different underlying mechanisms, and measuring physiological indices appears to be an effective method by which to evaluate the influence of mental stress.

Rushing, distraction, walking on contaminated floors and risk of slipping in limited-service restaurants: A case-crossover study
This nested case-crossover study examined the association between rushing, distraction and walking on a contaminated floor and the rate of slipping, and whether the effects varied according to weekly hours worked, job tenure and use of slip-resistant shoes. At baseline, workers from 30 limited-service restaurants in the United States reported average work hours, average weekly duration of exposure to each transient risk factor and job tenure at the current location. Use of slip-resistant shoes was determined. During the following 12 weeks, participants reported weekly their slip experience and exposures to the three transient exposures at the time of slipping. Among 396 participants providing baseline information, 210 reported one or more slips with a total of 989 slips. Rate of slipping was 2.9 times higher when rushing as compared to working at a normal pace. Rate of slipping was also significantly increased by distraction (relative risk (RR) 1.7) and walking on a contaminated floor (RR 14.6). Use of slip-resistant shoes decreased the effects of rushing and walking on a contaminated floor. Rate ratios for all three transient factors decreased as job tenure increased.

Active job, healthy job? Occupational stress and depression among hospital physicians in Taiwan
The objective of this study was to assess the levels and association of occupational stress and depression rate among physicians, and to compare physicians' occupational stress with that of Taiwanese employees in other occupations. The subjects were physicians employed at 14 participating regional hospitals. Self-administered questionnaires capturing data on demographics, occupational characteristics, occupational stress measured using Job Content Questionnaire and health status measured using Taiwanese Depression Questionnaire were sent to eligible physicians. Results revealed that the depression rate (13.3%) was higher than that found in the general population (3.7%) of Taiwan. The mean scores of the dimensions "work demands" and "job control" were both much higher than for most occupations in Taiwan. Higher depression scores were found in subjects with higher work demands, 8-10 days of being on duty per month and more frequent alcohol consumption, while lower depression scores were found in subjects working in the east Taiwan area, with higher job control and with greater workplace social support. Gender, smoking and working hour were not independently correlated with depression, but the interaction of gender and job control also had an independent effect on depression.

Can work make you sick? A meta-analysis of the relationships between job stressors and physical symptoms
A meta-analysis of 79 studies reporting cross-sectional and longitudinal relationships between physical symptoms and various occupational stressors was conducted. Stressors were organizational constraints, interpersonal conflict, role conflict, role ambiguity, workload, work hours, and lack of control. The relationships between stressors and eight physical symptoms were quantitatively summarized and contrasted, for both individual symptoms and composite symptom scales. All of the occupational stressors were significantly related to physical symptoms in cross-sectional analyses, and the effect sizes of these relationships varied both by the stressor and the individual symptom examined. The longitudinal relationships were similar to the cross-sectional results, and provided some evidence of temporal consistency of the occupational stressor/physical symptom relationship. Organizational constraints and interpersonal conflict had the strongest relationships with symptoms in both the cross-sectional and longitudinal analyses. Gastrointestinal problems and sleep disturbances were significantly related to more stressors than other symptoms examined. These findings show that it is important to examine physical symptoms, as they are related to a wide range of job stressors and these relationships prevail over time. Potential underlying mechanisms, including the immediacy of physiological reactions to stressors, participants' attributions concerning stressor/physical symptom relationships, and the possible multidimensional nature of symptoms, are proposed and discussed.

Effects of different physical workload parameters on mental workload and performance
The design and evaluation of an occupational task should include an assessment of mental workload, since excessive levels of mental workload can cause errors or delayed information processing. Physically demanding work that is performed concurrently with a cognitive task may impact mental workload by impairing mental processing or decreasing performance. The objective of this study was to determine whether there is a differential effect of various types of physical activity on both mental workload and cognitive performance. Objective and subjective assessment tools (heart rate variability and visual analogue scale) were used as indicators of mental workload, while correct responses during an arithmetic task reflected levels of performance. Thirty participants performed a combination of tasks involving both physical and mental workload. Changes in subjective ratings generally corresponded to changes in both performance on the arithmetic task and objective mental workload assessment. Some discrepancies occurred at the highest physical force exertion level as participants perceived an increase in effort to maintain the same level of performance.

Association between workaholism and sleep problems among hospital nurses
The present study examined the association between workaholism, the tendency to work excessively hard in a compulsive fashion, and sleep problems among Japanese nurses. A cross-sectional survey was conducted among 600 nurses from two university hospitals in Japan using a self-reported questionnaire on workaholism, sleep, job-related variables (job demands, job control and worksite support), and demographic variables. A total of 394 nurses returned the questionnaire (response rate 65.7%) and complete data from 312 female nurses were used for analyses (final coverage rate 52.0%). Workaholics, as measured using the Japanese version of the Dutch Workaholism Scale, were defined as those having high scores on both the "work excessively" and "work compulsively" subscales. Logistic regression analyses revealed that workaholics had higher risks for sleep problems in terms of subjective sleep insufficiency, excessive daytime sleepiness at work, difficulty awakening in the morning and feeling tired when waking up in the morning (odds ratios (OR) of 4.40, 3.18, 3.48 and 4.61, respectively). These remained significant even after adjusting for demographic and job-related variables (OR 3.41, 5.36, 2.56 and 2.77, respectively). However, no significant associations were found between workaholism and insomnia symptoms. These results suggest that workaholic nurses had higher risks for impaired awakening, insufficient sleep and workplace sleepiness.

Does intense time pressure at work make older employees more vulnerable? A statistical analysis based on a French survey "SVP50"
Two general trends, the tightening of time constraints and the ageing of the working population, are likely to raise sensitive issues implying adjustment of both work and workers' characteristics. The statistical studies presented in this article, referring to a French inter-professional survey conducted on health and work after fifty (sample of 11,213 employees), aim at verifying this assumption. The analyses presented are divided in four sub-questions: have part of the employees over fifty been removed from time pressure situations? Is time pressure difficult to deal with for older workers (from their point of view)? Does intense time pressure imply increased prevalence of certain health disorders among senior employees? Does pressure increase the desire to end one's professional life early? The results show that intense time pressure raises serious problems for most of the employees in their fifties who are exposed to them. 80% consider this constraint to be "difficult". They systematically show more frequent rates for most types of physical or psychological health disorders. "Sheltering from the job", which implies being shifted from work "under pressure" to a job "without pressure", is not uncommon but only solves a minority of situations. Lastly, the option of earlier retirement is not particularly developed in the age group in its fifties working "under pressure".

Less quick returns - Greater well-being
The aim of this study was to design ergonomically-improved shift schedules for nurses in primary health care shift work in order to enhance their health and well-being. The main change made was the reduction of quick returns (morning shifts immediately after an evening shift) in order to ensure more recovery time between work shifts. Six Finnish municipal hospital units and 75 nurses participated in the intervention. The aim was to maintain or improve the well-being and work ability of aged workers. Subjects were divided into three age groups: 20-40, 41-52 and 53-62 years. The introduction of more recovery time between evening and morning shifts significantly improved the subjects' sleep and alertness, well-being at work, perceived health and leisure-time activities independently of their age. The effect on social and family life was also positive. Other findings are discussed.

Mood change and perception of workload in Australian midwives
Twenty midwives in an Australian metropolitan hospital completed logbooks assessing daily fluctuations in subjective mood and workload. Participants also provided information about history of psychopathology and sleep quality. Workload factors significantly predicted mood at work. Specifically, when participants felt that their work was more demanding and frustrating and required more effort, or when they felt that they could not accomplish all that was expected, mood was negatively influenced. This supports the connection between workload and negative mood change in healthcare. Given the potential for mood to influence a multitude of functions relevant to safety, performance and psychosocial wellbeing it is important to understand the factors which influence mood, particularly in light of the current shortfall in the Australian healthcare workforce.

Managing emergencies and abnormal situations in air traffic control: Taskwork strategies (Part I); Teamwork strategies (Part II)
A large body of research in air traffic control has focused on human errors in decision making while little attention has been paid to the cognitive strategies employed by controllers in managing abnormal situations. This study examines the cognitive strategies in taskwork and teamwork that enable controllers to become resilient decision-makers. Two field studies were carried out where novice and experienced controllers were observed in simulator training in emergency and unusual scenarios. A prototype model of taskwork and teamwork strategies in air traffic management was developed and its construct validity was tested in the context of the field studies, leading to the development of a generic model of Taskwork and Teamwork strategies in Emergencies in Air traffic Management (T(2)EAM). Difficulties experienced by novice controllers are discussed, together with strategies employed by experts to manage uncertainty and balance workload during emergencies.

Sustainable MSD prevention: Management for continuous improvement between prevention and production. Ergonomic intervention in two assembly line companies
To increase output and meet customers' needs, companies have turned to various production management systems whose aim is to accelerate decisions, react to environmental issues and to continuously improve production performance. At the same time, regulation and control systems focusing on work-related risks have obliged firms to implement safety and health management systems such as OHSAS 18001. The purpose of this type of system, also based on continuous improvement, is to reduce risks, facilitate work-related activities and identify solutions in terms of equipment and tools. However, the prevention actions introduced through safety and health systems often result in other unexpected and unwanted effects on production. Using the examples of two manufacturing environments, this article discusses how companies can benefit by implementing both types of management system.

The operational demand evaluation checklist (ODEC) of workload for railway signalling
This study addressed the issue of the interpretation and assessment of mental workload of railway signallers, and in particular assessment of the load imposed by the work system. It highlights a framework created to direct the development of workload assessment tools capable of assessing the dimensions most relevant to the population being studied. A tool to capture the operational demands on the rail signaller was required to evaluate the load from the system they operated. The study describes the development of an Operational Demand Evaluation Checklist (ODEC), using techniques such as the repertory grid. The practical experience of the development, evaluation, live use and validation of ODEC is discussed and it is concluded that the approach could be adopted to interpret the concept of workload in other work domains.

Cardiorespiratory responses of firefighters to a computerized fire strategies and tactics drill during physical activity
Firefighters are subjected to a combination of physical and mental challenges in the course of their occupational responsibilities. However, due to the ecological factors involved with firefighting, it makes it extremely difficult to examine physiological and psychological changes that occur as a result of these combined challenges. The purpose of this study was to examine the efficacy of a computer-based Fire Strategies and Tactics Drill (FSTD) in eliciting psychological and physiological measures of stress in professional firefighters. The study involved 12 healthy firefighters from a metropolitan area of the United States. Participants responded to a medical history questionnaire and exercised under various conditions of oxygen consumption on a cycle ergometer. Findings are discussed. Results suggest that the FSTD provides an effective method for examining the physiological and psychological responses of firefighters in a research laboratory environment.

A longitudinal study of factors associated with intentions to leave among newly graduated nurses in eight advanced treatment hospitals in Japan
This study examined the factors associated with intentions to leave among newly graduated nurses (NGNs). Self-administered questionnaires were distributed to 567 NGNs in eight advanced treatment hospitals in Japan on two separate occasions approximately 6 months apart. The questionnaire items addressed individual attributes, employment and organizational characteristics and subjective health, and also included the 22-item Job Content Questionnaire, a scale of intentions to leave and a novel 21-item job readiness scale. Data from 301 NGNs who had participated in both questionnaire instances were used and subjected to hierarchical multiple regression analyses. Findings showed that while psychological distress was a more important predictor of intentions to leave during the first survey, cumulative fatigue was a more important predictor during the second survey. Other findings are discussed.

Driving with a congestion assistant: Mental workload and acceptance
In dense traffic conditions, drivers may be helped by a congestion assistant (CA), a system that includes an acoustic warning and accelerator pedal counterforce, together with automatic acceleration and braking. The objective of this study was to evaluate the mental load and the acceptance of driving with CA systems in a driving simulator. Data were obtained by means of questionnaires and continuous heart rate measurements. It is concluded that driving with the CA in dense traffic potentially leads to decreased driver mental workload. Acceptance is generally high after experiencing the system, though not in all respects. Other findings are discussed.

Autonomic nervous system and subjective ratings of strain in air-traffic control
The objective of this study was to evaluate the perceived mental strain among air-traffic controllers by means of self-evaluation and five physiological indicators from the autonomic nervous system, namely: skin potential, skin conductance, skin blood flow, skin temperature and heart rate. Each physiological variable was averaged to match the times spent monitoring a given number of aircraft. After the session, participants rated their stress using the NASA-TLX rating scale. Both subjective ratings and physiological values were closely correlated to the number of aircraft being monitored, which could evolve at random between one and ten. Results provide objective information to prevent air-traffic controllers from overloaded situations.

All day and all of the night: The relative contribution of two dimensions of workaholism to well-being in self-employed workers
The objective of this study was to examine the associations between workaholism and perceived health (exhaustion, physical complaints, and feelings of professional efficacy). It involved a sample of 477 Dutch self-employed workers. Workaholism is characterized by long work hours coupled with the inability to detach from work. It was expected that both workaholism components would be related to ill health. Variance and regression analyses revealed that this reasoning was confirmed for one component (inability to detach from work), but not for the other (working long hours).

Expert forecast on emerging psychosocial risks related to occupational safety and health
Significant changes which are taking place in the world of work lead to emerging psychosocial risks. Such risks, which are linked to the way work is designed, organized and managed, as well as to the economic and social context of work, result in an increased level of stress and can lead to serious deterioration of mental and physical health. In 2005, more than 20% of workers from the EU believed that their health is at risk because of work-related stress. This report presents the findings of an expert group on emerging psychosocial risks, supplemented by an analysis of the scientific research on key topics identified by the experts. A summary of the report is also available as a factsheet (CIS 08-250).

Safety and health in emergency services
Sicherheit und gesundheit im Rettungsdienst [in German]
A survey was carried out during 2004 in the 22 emergency services of the German Red Cross to evaluate the physical workload and psychological stress among emergency services workers. A standardized questionnaire was addressed to 382 workers, among whom 202 responded (163 men and 39 women). In addition, a subgroup of 98 subjects was followed during 48 working days. Despite a high level of job satisfaction, a low average age (33 years for men and 25 years for women) and a good work capacity index, subjects reported neck and shoulder pain, as well as low back and knee pain. Cardiofrequency measurements during work showed more rapid increases during emergency interventions than during simple patient handling. Salivary cortisol levels also showed similar differences. However no significant differences were found as a function of gender and age. Other findings are discussed.

Factors associated with changes in perceived strain at work among fire-fighters: A 3-year follow-up study
This study investigated individual and work-related psychosocial factors associated with perceived physical and mental strain among fire-fighters. It was carried out in the form of a 3-year follow-up questionnaire of 632 fire-fighters. The associations were investigated by logistic regression modelling. Accidents were associated with increased perceived physical as well as mental strain (odds ratio (OR) 1.4-2.6). Unfair distribution of work tasks was associated with increased perceived physical strain (OR 8.5). Frequent differences of opinion disturbing work (OR 2.7) and the lack of possibilities for career advancement (OR 4.6) were associated with perceived increased mental strain at work. These results suggest that a variety of measures are needed to reduce the perceived physical and mental strain of fire-fighters.

Job strain and neck-shoulder symptoms: A prevalence study of women and men white-collar workers
The objective of this cross sectional study of 1543 white-collar workers was to examine the association between psychosocial factors at work and the prevalence of neck and shoulder symptoms. Psychological demands and decision latitude at work were measured with Karasek's questionnaire. Workers exposed to high job strain had a higher prevalence of neck and shoulder symptoms (prevalence ratio (PR) 1.54). No effect of gender was observed in this association. The effect of job strain was stronger in workers with low social support (PR 1.84). These results suggest that primary prevention of neck and shoulder symptoms among white-collar workers should consider job strain, especially when workers have low social support at work.

Assessing mental constraints in relation to location and time
Erfassung psychischer Fehlbelastung unter den Aspekten Ort und Zeit [in German]
German legislation requires that workplace hazard evaluations also take into account an evaluation of occupational mental stress. This study examines whether one of the methods of screening for occupational mental stress risk factors, namely the SPA method, also enables the assessment of mental stress factors for jobs with variable working hours or workplace locations. Findings indicate that the SPA method allows the determination of occupational stress risk factors with sufficient precision and reliability. As far as flexible work is concerned, the outcome is that the risk of mental stress depends more on the content of work than on working hours or workplace location.

Workload, stress and psychosocial factors as hazards for musculoskeletal disorders
Musculoskeletal disorders (MSDs) resulting from work-related cumulative trauma continue to constitute a substantial problem in many workplaces. It is argued that current countermeasures address only one part of the problem because they usually fail to take adequate account of the important role of psychosocial and psychological stress factors as MSD risk factors. The nature and role of these risk factors are described in terms of an ergonomics model of work-related MSD risk. Key elements of the model are job demands, psychosocial factors, mental workload and stress. The empirical basis for this model is outlined, and the findings of studies on physiological mechanisms by which stress can increase the risk of MSDs are discussed. Based on this model, more effective management strategies to control non-physical MSD risk factors are identified.

Urinary catecholamines and salivary cortisol on workdays and days off in relation to job strain among female health care providers
This study examined the effects of psychosocial job strain on the excretion of neuroendocrine stress hormones (adrenaline, noradrenaline, and cortisol) on workdays and days off. 16 Japanese female health care providers filled out Karasek's job content questionnaire and had their neuroendocrine excretions (ie, urinary catecholamines and salivary cortisol) measured on a day off and on two workdays (one day shift and one night shift). Noradrenaline excretion was significantly greater over time in the high-strain group than in the low-strain group, and that of the high-demand group was significantly greater over time than that of the low-demand group. Adrenaline excretion did not significantly differ as a function of strain or demand, but was significantly higher in the group with high supervisory support than the group with low supervisory support. The concentration of salivary cortisol on a dayshift was significantly lower in the high-strain group than in the low-strain group. The implications of these findings are discussed.

Is job strain a major source of cardiovascular risk?
Empirical studies on job strain and cardiovascular disease (CVD), their internal validity, and the likely direction of biases were examined. The 17 longitudinal studies had the highest validity ratings. In all but two, biases towards the null dominated. Eight, including several of the largest, showed significant positive results; three had positive, nonsignificant findings. Six of nine case-control studies had significant positive findings; recall bias leading to overestimation appears to be fairly minimal. Four of eight cross-sectional studies had significant positive results. Men showed strong, consistent evidence of an association between exposure to job strain and CVD. The data for women were more sparse and less consistent, but, as for the men, most of the studies probably underestimated existing effects. Other elements of causal inference, particularly biological plausibility, corroborated that job strain is a major CVD risk factor.

Objective criteria for the evaluation of the workload resulting from psychosocial and organizational factors
Criterios objetivos para la evaluación de la carga de trabajo derivada de factores psicosociales y organizacionales [in Spanish]
The purpose of this research was to develop a computer-based tool for the objective evaluation of the mental workload resulting from psychosocial and organizational factors. The study focussed on two occupations, professors and telephone operators. This article describes the approach used for the detailed analysis of the jobs so as to highlight risk factors (psychological, organizational, social and relating to the layout of the premises). Two mental workload evaluation tools were developed as a result of this analysis, one for the university professors and the other for the telephone operators. They enable the evaluation of the hazards inherent to the job and to propose prevention measures.

High physical and psychosocial load at work and sickness absence due to neck pain
A prospective cohort study with a follow-up period of three years was performed among a working population in the Netherlands. At the beginning of the study, physical load at work was quantified by means of video recordings. Work-related psychosocial variables were measured by means of the Job Content Questionnaire. The frequency of sickness absence due to neck pain with a minimal duration of three days was assessed on the basis of company registrations during the follow-up period. Altogether 758 workers were included in the analyses. Possible confounding by individual characteristics, physical load, and psychosocial load was studied. Work-related neck flexion, neck rotation, low decision authority, and medium skill level are risk factors for sickness absence due to neck pain. There are indications that high job demands, low skill level, and low job security are also risk factors for sickness absence due to neck pain.

Effect of mental and physical demands on muscular activity during the use of a computer mouse and a keyboard
Twelve female subjects performed a computer task with four combinations of two types of input device (mouse and keyboard) and two levels of mental demand (with and without a Stroop colour word test). The time available for response was limited. Performance and electromyography (EMG) were recorded for the forearm, shoulder and neck muscles. All the muscles for which recordings were made showed increased muscular activity in the mentally demanding condition. The increase in the static muscular activity level varied from 0.3% of the maximum EMG for the right trapezius muscle to 2.6% for the extensor carpi ulnaris muscle. In conclusion, mental demands during computer work increased muscular activity in all of the recorded muscles. Increased muscular activity was found in the neck during the use of the mouse in comparison with the use of the keyboard. This phenomenon may be related to higher visual demands during the use of a mouse than with a keyboard. These findings may help explain the adverse effects of psychosocial work factors on the musculoskeletal system.

Increasing information load at the workplace: Strain-balanced coping with electronic media (e-mail, Internet)
Steigende Informationsflut am Arbeitsplatz: belastungsgünstiger Umgang mit elektronischen Medien (E-Mail, Internet) [in German]
Today, most office workers are equipped with personal computers connected to the Internet. The objective of this project was to examine how organizations and individuals perceive this new technology, the strain caused by information overload on employees and how they cope with this strain, as well as to evaluate supporting communication tools aimed at limiting this strain. Five studies on supporting communication tools, information organizational culture and psychological stress at the workplace due to the new media were conducted. On the basis of the findings, a training concept was developed for helping employees to cope with stress caused by this new technology.

Job stress, fatigue, and job dissatisfaction in Dutch lorry drivers: Towards an occupation specific model of job demands and control
Based on Karasek's model, this study examined the effects of job control, quantitative workload and occupation-specific job demands on fatigue and job dissatisfaction in Dutch lorry drivers. Information on job control, quantitative workload, physical demands, supervisor demands, fatigue and job dissatisfaction was gathered through questionnaires from 1181 lorry (truck) drivers. Data were subjected to multiple regression analyses. Inclusion of physical and supervisor demands in the model explained a significant amount of variance in fatigue (3%) and job dissatisfaction (7%). Moreover, in accordance with Karasek's interaction hypothesis, job control dampened the positive relation between quantitative workload and job dissatisfaction. The inclusion of occupation-specific job control and job demand factors gives occupational stress researchers a better insight into the relation between the psychosocial work environment and well-being.
