Comparing safety climate factors as predictors of work-related driving behavior

INTRODUCTION: Research suggests safety climate (SC) is a strong predictor of safety-related outcomes in organizations. This study explores the relationship between six SC dimensions and four aspects of work-related driving. METHOD: The SC factors measured were "communication and procedures," "work pressures," "relationships," "safety rules," "driver training," and "management commitment." The aspects of self-reported occupational driving measured were traffic violations, driver error, driving while distracted, and pre-trip vehicle maintenance. RESULTS: Hierarchical regression analyses revealed that the SC factors accounted for significant amounts of variance in all four aspects of work-related driving, over and above the control factors of age, sex, and work-related driving exposure. However, further investigation indicated certain SC factors (particularly safety rules, communication, and management commitment) were more strongly related to specific aspects of work-related driving behavior than others. Together, the SC factors were better able to predict self-reported distraction from the road than the other aspects of driving behavior measured. Implications for occupational safety, particularly for the management of work-related drivers are discussed.     

Supervisor behaviors,role stressors and uncertainty as predictors of personal outcomes for subordinates

Among employees of comparable organizations in the United States and New Zealand, role stressors (ambiguity and conflict), along with effort-to-performance uncertainty, performance-to-outcome uncertainty and doubt about acceptance by one's supervisor, generally predicted job satisfaction, psychological strain and turnover intentions. Path analyses of three alternative theoretical models highlighted the importance of job satisfaction as a mediator of the effects of role stressors and uncertainty on strain and turnover intentions. Role stressors contributed separately and via uncertainty to all three outcome measures, but subordinate perceptions of supervisor behaviors added little independent predictive power, once the role stressors and uncertainty were accounted for. These findings support the hypothesis that supervisors can influence the degree of role stress and uncertainty which their subordinates experience, which in turn may affect levels of satisfaction, strain and turnover intentions.     

Modeling attitudes and perceptions as predictors for changing safety margins during organizational change

This study describes the relations between different dimensions of leadership commitment, safety climate and attitudes toward change, and how these affect employee perceptions of safety during organizational change in a high risk environment. We collected data from a European national air navigation services provider during a volatile 3-year corporatization process that ended in the sudden collapse of a deliberate change implementation project. Surprisingly, despite visible signs of internal and external stress caused by the volatile and disruptive change process, we did not observe any change in the traditional safety metrics of incident and accident reporting during the study. The study is based on a large survey (n = 422) of individual attitudes and perceptions of safety climate, perception of leadership commitment to safety, attitudes to organizational change, and perception of safety. The data support the claim that perception of safety at least, in part, depends on individual perceptions of the leadership’s commitment to safety, and the safety climate in place at a given point in time. The model shows how employee perceptions of the leadership’s commitment to safety and safety climate are related to both attitudes toward change, and to perceived safety.     

Coping patterns as predictors of burnout: The function of control and escapist coping patterns

The paper attempts to bring concepts developed in cognitive approaches to stress and coping to a model which predicts burnout as a function of organizational demands and resources. Workers in a mental hospital (N = 177) provided information regarding coping patterns, burnout, and organizational commitment as well as various demands and resources in the work environment. A LISREL analysis confirmed that burnout is best considered a function of coping patterns as well as a function of organizational demands and resources. Control coping cognitions and actions were associated with decreased burnout, while escapist coping strategies were associated with increased burnout. The analysis indicated relationships of coping patterns with organizational commitment could be operating indirectly through the relationships of both coping patterns and commitment with the burnout. The paper discusses implications of these findings for interventions designed to alleviate or prevent burnout.     

Organizational politics and organizational support as predictors of work attitudes,job performance,and organizational citizenship behavior

This study investigated the relationship of organizational politics and organizational support to various work attitudes and behaviors among a field sample of 128 participants. Consistent with our hypothesis, politics and support were related to job satisfaction, commitment, turnover intentions, and supervisor ratings of organizational citizenship behaviors. However, only support was related to job performance. We also examined whether or not organizational politics and organizational support comprise two distinct constructs or one global factor. The evidence here was ambiguous. Fit indices obtained from confirmatory factor analysis suggested that it is more parsimonious to treat politics and support as opposite ends of the same construct, though the two‐factor model did show a slightly better fit. On the other hand, subsequent multiple regression analyses showed that support tended to account for additional criterion variance beyond the effect of politics, implying that there may be some practical utility to retaining politics and support as distinct constructs.

Freight transport and non-driving work duties as predictors of falling asleep at the wheel in urban areas of Crete

BACKGROUND: This study investigated the impact of subjective reports of drowsy driving and non-driving duties on the falling asleep responses and road crash involvement of professional drivers in Crete. An attempt was also made to elucidate other driving parameters, such as freight transportation, which could be potential predictors of risky driving, after controlling for lifestyle patterns. METHOD: A sample of 317 professional drivers was studied through personal interviews. The interview questionnaire included items about sleep and fatigue as contributing factors to falling asleep probability and crash risk. In addition, the drivers reported the type of freight they carried in their last trip, as well as practices such as smoking and alcohol consumption. RESULTS: The first logistic regression analysis showed that the most significant predictors of falling asleep at the wheel were transportation of fruits/vegetables and livestock, non-driving hours of work, insufficient hours of sleep, and smoking. The second logistic regression analysis revealed all the previous items as powerful factors of crash probability, including the transportation of express freight and freezer. IMPACT: The findings of the current study are discussed as they pertain to directions for future studies and for the development of fatigue countermeasures.     

The impact of visual perspective and anger on the actor-observer bias among automobile drivers

OBJECTIVE: The present study was designed to examine the combined impact of the Actor-Observer Bias and driver anger on attributions of other drivers. METHODS: Participants watched a simulated driving sequence in which a car swerved in front of a truck in near collision. Half viewed from the perspective of the offending motorist while the other half viewed from the perspective of a trailing motorist. Participants then rated the general riskiness of the offending motorist and the responsibility of the victim driver. RESULTS: Findings support the visual perspective explanation of the Actor-Observer Bias in that attributions within a single event differed based on the random assignment of visual perspective. However, the nature of the attributions interacted with the level of anger experienced over the incident. Those viewing as a trailing motorist provided greater riskiness ratings for the offending motorist than did those viewing from the perspective of the offending motorist, but only when scoring/rating high on personal feelings of anger regarding the observed incident. CONCLUSION: The present study demonstrates that personal factors and common cognitive biases can influence how events in the traffic environment are perceived, and the subsequent judgments made of other drivers following negative events.     

Attitudinal correlates and demographic predictors of monetary beliefs and behaviours

Nearly 300 adults completed a six-part, 69-item questionnaire derived from Forman (1987) on attitudes to, and uses and abuses of money, which measured six aspects of ‘money madness’ and various other questionnaires concerned with economic values and beliefs as well as work-related behaviours. Subjects thus completed 231 items in a total of six questionnaires half of which had subscales. The results indicated that the money pathology subscales were positively intercorrelated and have weak to moderate internal reliability. Multiple stepwise regressions of demographic and attitudinal variables onto the various money subscales showed political beliefs and work values to be the most powerful predictors. Results are discussed in terms of the very limited literature in the area.     

Workspace characteristics,behavioral interferences,and screening ability as joint predictors of employee reactions: An examination of the intensification approach

This study explored the joint moderating (i.e. intensifying) effect of two central workspace characteristics (i.e. number of people and number of enclosures) on the relationships between behavioral interferences and affective responses among individuals with high and low ability to screen. One hundred and fifty-two clerical employees from a large university participated in the study. The results suggest that individual reactions to behavioral interferences at work (i.e. work fatigue and psychosomatic complaints) are intensified by the joint presence of few enclosures and high number of people in the setting; however, this intensification effect appears to hold primarily among individuals with low screening ability. Thus, the joint moderating effect of workspace characteristics itself appears to be buffered (i.e. moderated) by personal ability to screen. Implications of the results and suggestions for future research are discussed.     

Electronic version of the encyclopaedia of occupational health and safety as a source of definitions

PROBLEM: Continuous progress in the occupational safety and health field, as well as social-economic development, generates a need for access to definitions. Definitions are usually scattered in many sources and not easy to find. Electronic documents give new opportunity to information access. METHOD: As an experiment, the feasibility of automatic full-text searching of definitions was examined using the Encyclopaedia of Occupational Health and Safety, edited by the International Labour Organization (ILO), on CD-ROM. DISCUSSION: The results were compared with the traditional index search by subject, using the paper version of the encyclopedia. The automatic search appeared successful; about 100 definitions were excerpted the automatic way. IMPACT ON INDUSTRY: As in most industries, finding accurate information is a necessity in the safety industry. The electronic document seems to be a powerful instrument as a source of definitions and can be quite easy to use by specialists as well as safety personnel in information processing.     

Prevention of musculoskeletal complaints in nursing: Aims, approach and content of an ergonomic-educational programme

In 1992 a comprehensive health-promotion project was initiated in seven nursing-homes in the Netherlands. This project was designed to implement an ergonomic-educational programme, with the intention of reducing physical workload and to bring about safe working in order to prevent work-related musculoskeletal complaints. After a period of external support, employees of the nursing-homes should be able to proceed with the programme independently. In this paper the content of the programme and its underlying strategies and theories are described. So far, the programme has got off to a good start in all the nursing-homes. Positive effects of the programme could be demonstrated and guidelines and protocols for safe working were introduced. However, it is as yet too early for definitive conclusions to be drawn regarding the aspect of continuity.     

Driving anger and its expressions: further evidence of validity and reliability for the Driving Anger Expression Inventory French adaptation

Introduction: The aims of this study were to provide further evidence of validity and reliability for the Driving Anger Expression Inventory (DAX) French adaptation (Villieux & Delhomme, 2008, Le Travail Humain, 71(4), 359-384) and to investigate the relationships between driving anger, how people express their anger while driving, and traffic violations among young drivers in France. Method: The French adaptations of the DAX, of the Driving Anger Scale (DAS), and of the Extended Violations Scale were administered to a sample of 314 drivers. Results: Confirmatory factor analysis of the French DAX items yielded a three factors solution with 11 items, which obtained better goodness-of-fit to the data. Cronbach α reliabilities for DAX factors ranged from .71 to .79. Aggressive forms of anger expression correlated positively with driving anger and traffic violations whereas the 'Adaptive/Constructive Expression' factor correlated negatively with these variables. Discussion: Globally, our results replicated earlier findings and showed that DAX factors are useful predictors of self reported violations and complement established measures like the DAS. Impact on Industry: Implications for driver education and interventions were examined.     

Physical limitations and musculoskeletal complaints associated with work in unusual or restricted postures: a literature review

INTRODUCTION: The vast majority of ergonomics research has addressed the demands of work in standing or sitting postures, and understandably so. However, many workers (e.g., underground miners, aircraft baggage handlers, plumbers, agricultural workers, mechanics, and others) are often required to adopt postures such as kneeling, stooping, squatting, or lying down for significant periods of the workday. METHOD: A literature search was performed using the ISI Web of Science database (for years 1980-2004). Articles retrieved from this search were evaluated in terms of relevance to assessing physical capabilities of workers in these postures and/or the musculoskeletal epidemiology associated with these postures. RESULTS: Work in unusual and restricted postures was associated with significantly higher rates of musculoskeletal complaints compared to workers not adopting these postures in epidemiology studies (Odds Ratios ranging from 1.13 to 13). Some studies suggested a dose-response relationship, with longer exposures leading to increased musculoskeletal complaints. Physical strength and psychophysical lifting capacity vary significantly as unusual or restricted postures are adopted, with lower lifting capacities evident in the kneeling, squatting, and lying positions. CONCLUSIONS: Workers who adopt unusual or restricted postures appear to be at higher risk of musculoskeletal complaints and often exhibit reduced strength and lifting capacity. Research needs in this area include improved exposure assessment tools, studies of intervention effectiveness, adaptations of the body in response of work in unusual postures, and elucidation of relevant injury pathways. IMPACT ON INDUSTRY: Workers who adopt unusual or restricted postures in their work often experience higher musculoskeletal injury rates. If awkward postures cannot be eliminated in the workplace, jobs should be designed in accordance with the reduced strength and lifting capabilities observed in these postures.

Cultural and socio-demographic predictors of car accident involvement in Norway,Ghana, Tanzania and Uganda

The prevalence of road traffic accidents is increasing towards endemic proportions in developing countries. The present study investigated cultural and demographic predictors of car accident involvement in a developed country in Europe and three developing countries in Sub-Saharan Africa. The comparison was carried out with questionnaires among a randomly obtained representative sample of the Norwegian population (n = 247) as well as stratified samples in Accra and Cape-Coast in Ghana (n = 299), Dar-es-Salaam and Arusha areas in Tanzania (n = 599), and the central Kampala and the Mbarara district in Uganda (n = 415). Measurement instruments of culture as symbol exchange and destiny orientation were used to predict self-reported road traffic accident involvement by car among the respondents. Demographic characteristics, such as gender, age and education, were also included as predictors of car accidents. The results showed that male gender was the only significant predictor of accident involvement in Norway. Introverted and extroverted culture, destiny orientation and written culture were associated with accident involvement in the African countries. Male gender also predicted accidents in these countries. Non-technical injury preventive countermeasures in developing countries could focus on cultural practice and fatalistic beliefs. Countermeasures in both developed and developing countries should target male drivers.
