The importance of self-efficacy in the moderating effects of social support on stressor–strain relationships

Abstract

Occupational stress research offers inconsistent findings on the moderating effects of social support on the stressor–strain relationship. This study contributes to the research literature by examining how social support's moderating effect is dependent on one's self-efficacy. Ninety-six US military police soldiers completed two surveys 3 months apart. The results showed that three out of four regression equations had significant three-way interactions. Organizational constraints×supervisor support×self-efficacy had statistically significant interactions in the prediction of job satisfaction and psychological well-being. Organizational constraints×co-worker support×self-efficacy had a significant interaction in the predicted of psychological well-being. These interactions explained between 5% and 10% of the variance in the dependent variables. Social support buffered the stressor–strain relationship when self-efficacy was high and reverse buffered the relationship when self-efficacy was low. These results indicate that interventions aimed at reducing strains by increasing social support should consider an individual's self-efficacy. Future research should consider incorporating content of communication to determine if high and low self-efficacy individuals receive or react differently to different types of communication content.     

Job tenure as a moderator of stressor-strain relations: A comparison of experienced and new-start teachers

Few studies have investigated the extent to which the effects of work stressors on strain change over the duration of employees' job incumbencies. Drawing on Karasek's (1979) job demands-control-support model, the current study examined the moderating influence of job tenure (experienced versus novice worker status) on stressor-strain relations. Using a sample of 422 experienced and 248 beginning schoolteachers in Australia, job factors and job strain were assessed on two occasions, 8 months apart. Analyses revealed that the three job factors were each correlated with strain as predicted, although the (elusive) demands×control interaction effect was evidenced amongst “new-start” teachers only. The findings provide mixed support for Karasek's model, and draw attention to the need to consider the role of job tenure and career stage in studies of work stress, as work stressor-strain effects may be routinely underestimated in research that ignores these factors.     

Negative affectivity and gender as moderators of the relationship between work-related stressors and depressed mood at work

The present study provided further evidence on the role of negative affectivity (NA) and gender as moderators of stressor-strain relations. Based on theoretical and empirical research, it was hypothesized that the moderating effects of NA would moderate the relationship between stressors (role ambiguity, workload, role conflict and interpersonal conflict) and work-related depression. Questionnaires were returned form 442 subjects of whom 74% were recruited from external degree courses and the rest were full-time employees. Results revealed significant three-way interactions for two of the four stressors (workload and role ambiguity) in predicting work-related depression. NA moderated the relationship between these stressors and work-related depression for females but not for males. These effects were modest, however. No significant interactions were found for role conflict and interpersonal conflict. The implications of these results are discssed.     

Job demands and work-related psychological responses among Malaysian technical workers: The moderating effects of self-efficacy

Abstract

Job design has long been found to affect the work-related psychological responses of employees, such as psychological strain, job satisfaction, and turnover intentions, but scholars have begun to question whether established theoretical relations regarding job design continue to hold given the enormous changes in the nature of work during the past two decades. It is also increasingly recognized that individual differences affect work behaviours in substantial ways, but few studies on work design have investigated these differences. We addressed these concerns with a two-wave longitudinal study among 245 technical workers at a telecommunications company in Malaysia, a country that has a collectivist culture and a high power distance between managers and subordinates. We examined the moderating effects of job control and self-efficacy on the relationships between job demands and employee responses. The results failed to support the job demands-control model, as job control variables did not moderate the impact of demands on employee work-related psychological responses. However, self-efficacy moderated their impact on psychological strain (although not on job satisfaction or turnover intentions). Our findings provide insight into the moderating effect of self-efficacy, and suggest that practitioners interested in reducing psychological strain should consider making efforts to increase self-efficacy among employees.

The Job Demand-Control (-Support) Model and psychological well-being: A review of 20 years of empirical research

The Job Demand-Control (JDC) model (Karasek, 1979) and the Job Demand-Control-Support (JDCS) model (Johnson, and Hall, 1988) have dominated research on occupational stress in the last 20 years. This detailed narrative review focuses on the JDC(S) model in relation to psychological well-being. It covers research from 63 samples, published in the period 1979-1997. In the review a distinction is drawn between two different hypotheses prevailing in research on the models. According to the strain hypothesis of the JDC model, employees working in a high-strain job (high demands-low control) experience the lowest well-being. The buffer hypothesis states that control can moderate the negative effects of high demands on well-being. Translating these hypotheses to the expanded JDCS model, the iso-strain hypothesis predicts the most negative outcomes among workers in an iso-strain job (high demands-low control-low social support/isolation), whereas the buffer hypothesis states that social support can moderate the negative impact of high strain on well-being. Although the literature gives considerable support for the strain and iso-strain hypotheses, support for the moderating influence of job control and social support is less consistent. The conceptualization of demands and control is a key factor in discriminating supportive from nonsupportive studies. Only aspects of job control that correspond to the specific demands of a given job moderate the impact of high demands on well-being. Furthermore, certain subpopulations appear to be more vulnerable to high (iso)strain, whereas others benefit more from high control. On the basis of the results of this review, suggestions for future research and theoretical development are formulated.     

Exposure to occupational violence and the buffering effects of intra-oranizational support

This paper presents a conceptually distinct analysis of the data first reported by Leather et al. Specifically, it investigates the effects of exposure to a variety of forms of work-related violence upon work attitudes and general well-being within a sample of UK public house licensees—individuals who manage public houses and hold the licence permitting the sale of alcoholic drinks on the premises. In addition, it examines the role of social support in moderating such effects. Based upon a sample of 242 licensees, it reports a consistent interaction between exposure to such violence and the availability of perceived intra-organizational support in determining the size of any negative effects upon individual well-being, job satisfaction and organizational commitment. It is argued that exposure to all forms of work-related violence, including intimidation, verbal abuse and threat, should be seen as a potential stressor within the work environment, the negative effects of which are buffered by perceived support from within the organization, but not by that perceived to be available from informal sources such as family and friends.

Work hours and well-being: The roles of work-time control and work-family interference

This study focused on mediating and moderating processes underlying the relationship between work hours and well-being. Questionnaire data from 292 female employees in two UK public sector organizations were analysed. Drawing on effort-recovery theory and published empirical findings, it was hypothesized that work-family interference (WIF) would mediate the relationship between work hours and measures of well-being (psychological distress and family satisfaction), and that work-time control would moderate the association between work hours and WIF. Hierarchical regression analyses showed that, after controlling for demographic variables, neuroticism, and job demands, WIF mediated the effect of work hours on family satisfaction, although no evidence of mediation was found for the psychological distress outcome measure. Work-time control moderated the relationship between work hours and WIF; higher control buffered the effect of longer hours on WIF. These findings add to the literature on the role of WIF in the effort-recovery process by showing that longer work hours are not necessarily associated with higher work-family interference, and hence with poor recovery and impaired well-being. Instead, having a degree of control over work hours moderates the first link in this process. Thus, the provision by employers of some flexibility and control over work hours may help to reduce the potential negative impact of long work hours on employees.     

Moderating effects of social support in shiftworking and non-shiftworking nurses

The effects of social support on the job stress (role ambiguity)-strain (job dissatisfaction, intent-to-turnover, health problems) relationship were investigated in shiftworking (second and third shifts) and non-shiftworking (first shift) groups of nurses (N = 191). Previous research indicates that shiftworkers frequently report problems of social integration as a negative aspect of their jobs. Additionally, shiftworkers demonstrate a number of stress-related illnesses. Social support has been hypothesized to show its strongest stress-buffering (i.e. moderating) effects in high stress environments. In other words, persons with higher levels of social support are less likely to be negatively affected by high stress environments. It was hypothesized that individuals working on shiftwork would demonstrate stronger moderating effects of social support on the job stress-strain relationship than non-shiftworkers because of the stressful nature of shiftwork and the importance of social integration difficulties to shiftworkers. The dependent measures used in the analyses were global job satisfaction, intent-to-quit, and perceived health problems. Main and moderating effects of social support were found for several of the analyses. For shiftworkers, this buffering effect was significantly greater for supervisor social support on global job satisfaction and intent-to-quit. Implications of the findings are discussed.     

Psychological empowerment and organizational commitment: the moderating effect of organizational learning culture

This paper examines the influence of psychological empowerment on organizational commitment and the moderating effect of organizational learning culture on the relationship. The results suggest that psychological empowerment, organizational learning culture, and demographic variables had a significant impact on organizational commitment for employees in the public sector of Korea. Employees showed higher organizational commitment when they perceived high psychological empowerment and a high organizational learning culture. In addition, the moderating effect of organizational learning culture on the relationship between psychological empowerment and organizational commitment was found to be significant. Among the demographic variables, only educational level turned out to be significant. Finally, implications, limitations and research recommendations are discussed.     

All I want for Christmas is recovery – changes in employee affective well-being before and after vacation

Abstract

Transformational leaders employ a visionary and creative style of leadership that inspires employees to make independent decisions and develop in their work. There is some evidence that the transformational (inspirational) leadership style is linked to employee burnout and stress. However, little research has focused on the psychological mechanisms that could explain this link, nor has there been a focus on positive affective well-being. We propose that transformational leaders influence their followers' self-efficacy, thereby affecting affective well-being in followers. This study extends previous work by examining the direct link between leadership and well-being both cross-sectionally (N=447) and longitudinally (N=188), and testing the mediating effects of self-efficacy. The study was carried out within parts of an elderly care department in a Danish local government. A theory-driven model of the relationships between leadership, self-efficacy and affective well-being was tested using Structural Equation Modelling. The results indicated that followers' self-ratings of self-efficacy mediated the relationship between transformational leadership style and positive affective well-being. Only limited evidence for a direct path between leadership behaviour and positive affective well-being was found. These findings have implications for how organizations may promote employee well-being, through interventions directed at supporting transformational leadership behaviours.     

Employees' perceptions of organizational restructuring: The role of social support

Organizational change and restructuring is often perceived as leading to increased occupational stress, impacting negatively on the psychological well-being of employees. This pragmatic study investigates the role of social support and dispositional affect as moderators of role stress post-restructuring for employees in a public utility company. A total of 176 employees, including 37 managers, 60 graded staff and 78 industrial staff completed a self-report questionnaire, approximately 1 year postrestructuring, retrospectively assessing role conflict, ambiguity, overload and positive and negative feedback pre- and post-restructuring. Results suggested that overall role stress increased for managers/ senior officers and graded staff, but not for industrial staff. Social support was linked with lower role stress, more positive feedback and less negative feedback at post-restructuring. For certain role stressors this impact was moderated by dispositional affect, but the effect was not consistent across occupational groups. Positive affect enhanced the effect of manager support in reducing role conflict for graded staff, and the effect of co-worker support in increasing positive feedback and reducing negative feedback for industrial staff. Findings suggest that managers should pay particular attention to support and feedback for employees during periods of chronic occupational stress following organizational restructuring.     

The role of sense of coherence in well-being at work: Analysis of main and moderator effects

Abstract

The aim of this cross-sectional study was to investigate the role of the sense of coherence (SOC) as a main effect on well-being and also its possible moderating role in the relationship between work characteristics and well-being in a sample of Finnish technical designers (n = 989). MANOVA/MANCOVA analysis with hierarchical decomposition was used so that the demographic variables (age, occupation gender) were controlled throughout. The results offered strong support for a main effect model of SOC: the stronger the SOC, the lower the level of psychosomatic symptoms and emotional exhaustion. Also, some support for a moderating role of SOC on the relationships between perceived work characteristics and well-being was found. However, these relationships explained only a small proportion of the variance of well-being was found. However, these relationships explained only a small proportion of the variance of well-being indicators. These results showed that the strong SOC subjects seemed to be better protected from the adverse effects of certain work characteristics (e.g. pressure of time). Furthermore, good social relations at work emphasized well-being among subjects with a very weak SOC, whereas these relations matered less in determining well-being outcomes in subjects with a stronger SOC. Finally, some work characteristics seemed to have salutary effects on well-being when accompained by a strong SOC and, on the contrary, pathogenic effects when accompained by a weak SOC.

Abstract

In the field of stress research it is often assumed that social support as well as coping behaviour contributes to feelings of health and well-being. However, until now it has not been altogether clear whether a main-effect model or a buffer model was the more appropriate for explaining the role of these factors in response to stressful situations. In this paper, a research project is described in which both the direct and indirect effects of social support and coping were studied in the work situation of nurses. The results offer more support for a main-effect model than for a buffer or moderating-effect model, especially with regard to the coping strategies ‘active problem-solving’ and ‘palliative behaviour’. However, some moderating effects on nurses‘ reactions to their work situation were found for social support and for ‘comforting cognitions’ as a coping strategy.     

How and when is social networking important? Comparing European expatriate adjustment in China and Turkey

Social interaction has been demonstrated to be a main predictor of expatriate adjustment. However, the impact of social interaction on expatriate adjustment may vary for those in different cultures. Contextual factors, such as geographic proximity and cultural differences between the home country and the host country, may have a significant impact on the expatriate adjustment process. The current paper singles out the above contextual factors by comparing European expatriates in China and in Turkey. European expatriates in China (n = 61) and Turkey (n = 69) were surveyed to explore the different patterns of social interactions (personal network and support), and the impact of these on the psychological well-being of the two groups. The empirical evidence gathered by the current study will delineate these differences and similarities and their impacts on the expatriates' psychological well-being in these two host countries.

The effects of JDC model on burnout and work engagement: A multiple interaction analysis

This study investigated the moderating effects of functional social support (emotional and instrumental support) on the relationship of job demand control with burnout and work engagement. In total, 297 frontline employees from a hotpot restaurant franchise in China were surveyed. The results indicated emotional support, such as caring and inspiration, mitigated the adverse effects of high demand/low control on burnout and work engagement. Instrumental support, such as giving suggestions and solving problems, only mitigated the adverse effects of burnout. Further, the high demand/low control/low emotional support work condition was the most unfavourable for work engagement and burnout; while high demand/low control/low instrumental support was the most unfavourable condition for burnout. The theoretical and managerial implications of this research have been provided to gain a deeper insight into functional social support in the job demand control model.

Findings suggest that managers should pay particular attention to support and feedback for employees during periods of chronic occupational stress following organizational restructuring.     

The contribution of supervisor behaviour to employee psychological well-being

Many employees affirm that supervisors affect employee well-being, and research has demonstrated associations between supervisor behaviour and employee psychological well-being. However, what hasn't been clear is the extent to which the association with supervisor behaviour compares with that of other variables known to affect well-being. This exploratory study addresses that issue. Our hypothesis was that supervisor behaviour can contribute to the prediction of psychiatric disturbance beyond the contribution of other influential variables. We created a new, questionnaire-based instrument to measure supervisor behaviour. We tested our hypothesis using stepwise regression with a convenience sample of 167 men and women working in a variety of organizations, occupations, and industries in the USA. Results supported our hypothesis: supervisor behaviour made a statistically significant contribution to the prediction of psychiatric disturbance beyond a step-one variate comprised of age, health practices, support from other people at work, support from home, stressful life events, and stressful work events. This provides additional evidence that supervisor behaviour can affect employee well-being and suggests that those seeking to create healthier workplaces should not neglect supervision. We believe that there is now ample justification for those concerned with psychosocial working conditions to consider supervisor behaviour as a potentially influential variable.

Furthermore, we believe that we have presented a new instrument for assessing supervisor behaviour that has the potential to be of value in future studies.
