Introduction to special issue on burnout and health

Abstract

In recent years, the issue of occupational stress and burnout have received increasing research attention. Given the amount of time people spend on work-related activities and the central importance of work to one's sense of identity and self-worth, it is not surprising that occupational stress is regarded as a central area of study. Although burnout is linked to the extensive literature on occupational health, burnout goes beyond occupational health by focusing on specific stressors in the workplace to emphasize total life and environmental pressures affecting health.     

Measuring driver-vehicle cooperation: Development and validation of the Human-Machine-Interaction-Interdependence Questionnaire (HMII)

The development of partially and highly autonomous vehicles that take over parts of the driving task will result in changes in e.g. the responsibilities, interface and system design, task allocation and communication between driver and automated vehicle. To support this change and the increasing space of cooperative possibilities between driver and vehicle, generally accepted design principles and preconditions for successful driver-vehicle cooperation (Directability, Mutual Predictability, Joint Goals and Mutual Task-Dependency) were defined. However, research lacks validated scales measuring the proposed basic principles of driver-vehicle cooperation. Furthermore, a theory is missing that links those basic principles with a theory that enables an understanding of the influence of drivers' perception of the autonomous vehicle and context on driver-vehicle cooperation. Therefore, this work links the basic theoretical principles of driver-vehicle cooperation with the social psychological Theory of Interdependence and their dimensions (Conflict, Power, Mutual Dependence, Information Certainty, Future Interdependence). Filling the gap of missing validated scales for the principles of driver-vehicle cooperation, this study provides the development and validation of the Human-Machine-Interaction-Interdependence (HMII) questionnaire.In two studies, the new HMII questionnaire to measure drivers' perception in driver-vehicle cooperation was developed. In the first study (n = 94), items for the perception of the situation were transferred from the original Theory of Interdependence to the driver-vehicle cooperation. A 7-dimension model was identified via Explorative Factor Analysis. In the second study (n = 314), the model and items were validated via confirmatory factor analysis. A seven-factor model (Power, Conflict, Mutual Dependence Information Certainty: System to Human, Information Certainty (two levels) Future Interdependence (two levels) with 33 items showed a good fit to the data, chi² = 841, p < .001, adjusted chi² = 1.77, SRMR = 0.071. In sum, this questionnaire can help designers evaluate the impact of their system designs on driver perceptions of the driver-vehicle cooperation.     

Social network as a moderator in the relation between trauma exposure and trauma reaction: a survey among UN soldiers and relief workers

Social network as a moderator between trauma exposure and post-trauma symptomatology was studied. Two samples--relief workers and UN soldiers--were assessed on trauma exposure, social network and three dependent measures related to post-trauma reactions. Regression analysis and interaction plots were used to determine the presence of interaction effects between trauma exposure and social network. All four network variables moderated the relationship between trauma exposure and post-trauma reactions among relief workers, while among UN soldiers only two such buffer effects were found. Furthermore, among UN soldiers one of these interaction effects was reversed, indicating social support to be important for those low on trauma exposure, while among relief workers support was important in the high-exposure condition. The results indicate a difference with respect to the importance of social network as a moderator between groups exposed to different kinds of war trauma. Differences in motivational systems may also exist. However, further research will have to establish this.     

Is sense of coherence a mediator or moderator of relationships between violence at work and stress reactions?

The relationships between exposure to violence at work, sense of coherence, and stress reactions were analysed in a large sample of the Danish workforce. The results showed that employees subjected to violence have a weaker sense of coherence than the rest of the respondents. Sense of coherence acted as a mediator and not as a moderator of relationships between exposure to violence and psychological, psychosomatic and cognitive stress reactions. The stability of the sense of coherence construct is discussed. With respect to the relation between sense of coherence and violence, preventative measures at the individual and organizational level are suggested.     

Measures of infant self-regulation during the first year of life: A systematic review

This study aimed to systematically review the measures used to assess infant self-regulation during the first 12 months of life. This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement protocol. From 235 selected papers, 79 provided information on behavioural and physiological measures to assess infant self-regulation during the first 12 months of life. Thirty-six behavioural (30 observational and 6 parent-report) and five physiological different measures were identified. Studies with a longitudinal design, comprising larger samples, and aiming to assess infant self-regulation later in infancy, mostly used behavioural measures than physiological measures. Studies comprising lower samples and aiming to assess infant self-regulation earlier in infancy, mostly used observational than parent-reported measures. Studies targeting younger infants used physiological measures and studies targeting older infants used behavioural measures, with observational measures used with younger infants and parental-reported measures used with older infants during the first year of life. When measuring self-regulation is important to consider infant's age, to fit the measurement procedures with the self-regulation development level.     

Perceived unpleasantness and facial reactions to auditory stimuli

This study examined whether facial electromyographic (EMG) reactions differentiate between identical tone stimuli which subjects perceive as differently unpleasant. Subjects were repeatedly exposed to a 1000 Hz 75 dB tone stimulus while their facial EMG from the corrugator and zygomatic muscle regions were measured. Skin conductance and heart rate responses were also measured. The subjects rated the unpleasantness of the stimulus and based on these ratings they were divided into two groups, High and Low in perceived unpleasantness. As predicted the facial EMG activity reflected the perceived unpleasantness. That is, the High group but not the Low group reacted with an increased corrugator response. The autonomic data, on the other hand, did not differ between groups. The results are consistent with the proposition that the facial muscles function as a readout system for emotional reactions and that facial muscle activity is intimately related to the experiential level of the emotional response system.     

Contesting orientations,self-determined motivation,and sportspersonship: Further validation of the contesting orientations scale

ObjectivesTo examine the factorial validity of the Contesting Orientations Scale (COS) in a large sample of intercollegiate student-athletes, as well as to extend evidence of the COS’ concurrent validity by examining its relationship to autonomous and controlled motivations in sport. The ability of contesting orientations to predict sportspersonship over and above autonomous and controlled motivations was also examined.DesignCross-sectional and correlational.MethodsFive hundred and forty-four intercollegiate US athletes (57.2% male) from individual and team sports completed measures of contesting orientations, autonomous and controlled motivations, and sportspersonship.ResultsConfirmatory factor analysis (CFA) supported the factorial validity of the COS, while correlational results supported its concurrent construct validity, with autonomous motivation associated with higher levels of partnership orientation and controlled motivation associated with higher levels of war orientation. In addition, sequential regression analyses supported the predictive utility of contesting orientations, with partnership orientation emerging as a significant positive predictor of four – and war orientation a negative predictor of three – dimensions of sportspersonship. Mediation analyses suggested that contesting orientations may partially mediate the relationship between autonomous and controlled motivations for some dimensions of sportspersonship.ConclusionsThe COS is a valid and reliable measure of contesting orientations. Partnership and war contesting orientations, moreover, add significantly to the prediction of sportspersonship over and above autonomous and controlled motivations. In practice, if the goal is to promote good sportspersonship, coaches and other adults involved in competitive sport should emphasize a partnership contesting orientation in addition to more autonomous forms of motivation.     

Exploring Correlates of Alcohol-Specific Social Reactions in Alcohol-Involved Sexual Assaults

This exploratory study examined demographic, assault, and disclosure factors as predictors of survivors’ decisions to disclose preassault alcohol use and social reactions to their preassault alcohol use. Of survivors drinking prior to assault, those with more education and greater alcohol impairment or resistance during assault were more likely to disclose preassault drinking. Of women disclosing preassault drinking, those with more education and more violent assaults received more negative social reactions specific to their preassault drinking. Such negative reactions were more common for those telling parents, police, or medical professionals. Women with less education received more positive and negative social reactions specific to their preassault drinking. Disclosing preassault drinking in greater detail was related to positive social reactions specific to preassault drinking and greater alcohol impairment during assault was associated with both positive and negative social reactions specific to preassault drinking. Implications for research and intervention are provided for survivors disclosing alcohol-related sexual assaults.     

On the Origins of Children's Compliance and Opposition: Family Context, Reinforcement, and Rules

Interactional synchrony and context dependent reinforcement are presented as similar phenomena in this discussion of children's dispositions to comply with or to oppose parental instructions. I argue that consistent and appropriate parental reactions to the full range of a child's response repertoire will establish a family context conducive to positive reinforcement of child compliance. In contrast, inconsistent parental reactions appear to create a chaotic family context conducive to the negative reinforcement of child opposition. Depending on these two forms of context, the parents and children seem to generate distinctive personal rules which outline the functional arrangements of context, behavior and reinforcement. The importance of these personal rules in helping parents and children to improve the lawfulness of family context is highlighted.
