A test of the job demands : resources model with HIV/AIDS volunteers

Burnout has been identified as a significant factor in HIV/AIDS volunteering. It has been associated with depression, anxiety and the loss of volunteers from the health care delivery system. The aim of this study was to test the independence of the health and motivational processes hypothesized within the Job Demands – Resources model of burnout in HIV/AIDS volunteers. Participants were 307 HIV/AIDS volunteers from state AIDS Councils throughout Australia who completed self-report measures pertaining to role ambiguity and role conflict, social support, burnout, intrinsic and organizational satisfaction, and depression. Findings suggested that the independence of the dual processes hypothesized by the model was only partially supported. These findings provide a model for burnout which gives a framework for interventions at both the individual and organizational level which would contribute to the prevention of burnout, depression, and job dissatisfaction in HIV/AIDS volunteers.

Emotional intelligence and job-demands resources model

Occupational stress research has consistently demonstrated negative effects for employees. Research also describes potential moderators of this relationship. While research has revealed some positive effects of emotional intelligence (EI) on employee adjustment, it has neglected investigation of their potential stress buffering effects. Based on the Job-Demand Resources model, it was predicted that higher trait emotional intelligence would act as a buffer to the potential negative effects of stressors on employee adjustment. Hierarchical multiple regression analyses with a sample of 306 nurses found no main effects of EI but revealed eight moderating effects. While some interactions support the buffering hypothesis, others revealed buffering for those with low EI. Findings are discussed in terms of theoretical and practical implications.

Burnout and work engagement among teachers: an application of the job demands-resources model

The present dissertation focuses on burnout and work engagement among teachers, with especial focus on the Job-Demands Resources Model: Chapter 1 focuses on teacher burnout. It aims to investigate the role of efficacy beliefs using negatively worded inefficacy items instead of positive ones and to establish whether depersonalization and cynism can be considered two different dimensions of the teacher burnout syndrome. Chapter 2 investigates the factorial validity of the instruments used to measure work engagement (i.e. Utrecht Work Engagement Scale, UWES-17 and UWES-9). Moreover, because the current study is partly longitudinal in nature, also the stability across time of engagement can be investigated. Finally, based on cluster-analyses, two groups that differ in levels of engagement are compared as far as their job- and personal resources (i.e. possibilities for personal development, work-life balance, and self-efficacy), positive organizational attitudes and behaviours (i.e., job satisfaction and organizational citizenship behaviour) and perceived health are concerned. Chapter 3 tests the JD-R model in a longitudinal way, by integrating also the role of personal resources (i.e. self-efficacy). This chapter seeks answers to questions on what are the most important job demands, job and personal resources contributing to discriminate burned-out teachers from non-burned-out teachers, as well as engaged teachers from non-engaged teachers. Chapter 4 uses a diary study to extend knowledge about the dynamic nature of the JD-R model by considering between- and within-person variations with regard to both motivational and health impairment processes.

Curvilinear relationships between the job demands-resources (JD-R) model, and work engagement : a police service case study

The current study aims to investigate the non-linear relationship between the JD-R model and work engagement. Previous research has identified linear relationships between these constructs; however there are strong theoretical arguments for testing curvilinear relationships (e.g., Warr, 1987). Data were collected via a self-report online survey from officers of one Australian police service (N = 2,626). Results demonstrated a curvilinear relationship between job demands and job resources and engagement. Gender (as a control variable) was also found to be a significant predictor of work engagement. The results indicated that male police officers experienced significantly higher job demands and colleague support than female officers. However, female police officers reported significantly higher levels of work engagement than male officers. This study emphasises the need to test curvilinear relationships, as well as simple linear associations, when measuring psychological health.

Job Demands and Organizational Citizenship Behavior: The Roles of Organizational Commitment and Social Interaction

Drawing from the Job Demands-Resources (JD-R) model and research on social exchange relationships, this study investigates the impact of three job demands (work overload, interpersonal conflict, and dissatisfaction with the organization’s current situation) on employees’ organizational citizenship behavior (OCB), the hitherto unexplored mediating role of organizational commitment in the link between job demands and organizational citizenship behavior (OCB), as well as how this mediating effect might be moderated by social interaction. Using a multi-source, two-wave research design, surveys were administered to 707 employees and their supervisors in a Mexican-based organization. The hypotheses were tested with hierarchical regression analysis. The results indicate a direct negative relationship between interpersonal conflict and OCB, and a mediating effect of organizational commitment for interpersonal conflict and dissatisfaction with the organization’s current situation. Further, social interaction moderates the mediating effect of organizational commitment for each of the three job demands such that the mediating effect is weaker at higher levels of social interaction. The study suggests that organizations aiming to instill OCB among their employees should match the immediate work context surrounding their task execution with an internal environment that promotes informal relationship building.

Work-family conflict, burnout and work engagement among teachers: The moderating effect of job and personal resources

The present study contributes to the literature on the Job Demands-resources model in the italian school context. the aim of this paper is to examine how the interaction between work-family conflict (i.e., a typical job demand) and opportunities to learn and to develop and self-efficacy (i.e., typical job and personal resources, respectively) affect the core dimensions of burnout (exhaustion and depersonalization) and work engagement (vigor and dedication). Hypotheses were tested with a cross-sectional design among 143 teachers of a junior high school in the north of Italy. Results of moderated multiple regression analysis partially supported the hypotheses as the opportunities to learn and to develop buffered against the aversive effects of work-family conflict on depersonalization, whereas self-efficacy moderated the relationship between work-family conflict and vigor. From a practical viewpoint, our findings suggest that opportunities to learn and to develop and self-efficacy are important re- sources that help teachers to reduce the negative effects related to work-family conflict.

Focus on opportunities as a boundary condition of the relationship between job control and work engagement: A multi-sample, multi-method study

The concept of focus on opportunities describes how many new goals, options, and possibilities employees believe to have in their personal future at work. In this multi-sample, multi-method study, the authors investigated relationships between focus on opportunities and general and daily work engagement and the moderating role of focus on opportunities on between- and within-person relationships between job control and work engagement. Based on a social cognitive theory framework on the motivating potential of a future temporal focus, it was hypothesized that focus on opportunities is positively related to work engagement. Further, consistent with the notion of compensatory resources, it was expected that job control is not related to work engagement among employees with a high focus on opportunities, whereas job control, as an external resource of the work environment, is positively related to work engagement among employees with a low focus on opportunities. Both a cross-sectional survey study (N=174) and a daily diary study (N=64) supported the hypotheses. The study contributes to research on the job demands-resources model as it emphasizes the role of focus on opportunities as a motivational factor in the relationship between job control and work engagement.

An Examination of Psychological Meaningfulness, Safety, and Availability as the Underlying Mechanisms linking Job Features and Personal Characteristics to Work Engagement

The present study tested a nomological net of work engagement that was derived from its extant research. Two of the main work engagement models that have been presented and empirically tested in the literature, the JD-R model and Kahn’s model, were integrated to test the effects that job features and personal characteristics can have on work engagement through the psychological conditions of meaningfulness, safety, and availability. In this study, safety refers to psychological perceptions of safety and not workplace safety behaviors. The job features that were tested in this model included person-job fit, autonomy, co-worker relations, supervisor support, procedural justice, and interactional justice, while the personal characteristics consisted of self-consciousness, self-efficacy, extraversion, and neuroticism. Thirty-four hypotheses and a conceptual model were tested in order to establish the viability of this nomological net of work engagement in which it was expected that meaningfulness would mediate the relationships between job features and work engagement, safety would mediate the relationships that job features and personal characteristics have with work engagement, and availability (physical, emotional, and cognitive resources) would mediate the relationships that personal characteristics have with work engagement. Furthermore, analyses were run in order to determine the factor structure of work engagement, assess whether or not it exhibits differential validity from organizational commitment and job satisfaction, and confirm that it is positively related to the outcome variable of organizational citizenship behavior (OCB). The final sample consisted of 500 workers from an online labor market who responded to a questionnaire composed of measures of all constructs included in this study. Findings show that work engagement is best represented as a three-factor construct, composed of vigor, dedication and absorption. Furthermore, support was found for the distinction of work engagement from the related constructs of organizational commitment and job satisfaction. With regard to the proposed model, meaningfulness proved to be the strongest predictor of work engagement. Results show that it partially mediates the relationships that all job features have with work engagement. Safety proved to be a partial mediator of the relationships that autonomy, co-worker relations, supervisor support, procedural justice, interactional justice, and self-efficacy have with work engagement, and fully mediate the relationship between neuroticism and work engagement. Findings also show that availability partially mediates the positive relationships that extraversion and self-efficacy have with work engagement, and fully mediates the negative relationship that neuroticism has with work engagement. Finally, a positive relationship was found between work engagement and OCB. Research and organizational implications are discussed.

Exploration de la dynamique entre les demandes, ressources au travail et la santé psychologique au travail.

Plusieurs interventions visant à améliorer la santé psychologique au travail reposent sur une conceptualisation pathogénique où celle-ci est représentée par une absence d’états psychologiques négatifs (Randall & Nielsen, 2010). Or, elle représenterait à la fois l’absence d’états négatifs de détresse psychologique au travail et la présence d’états positifs de bien-être psychologique au travail (Gilbert, Dagenais-Desmarais, & Savoie, 2011). Ceci suggère qu’afin de maximiser l’impact des interventions, il serait pertinent d’indiquer aux intervenants des leviers pouvant influencer les volets positifs et négatifs de la santé psychologique au travail. Parmi ces leviers, Gilbert (2009) a identifié les demandes et les ressources au travail. Cependant, les modèles théoriques traitant de l’impact de demandes et de ressources sur des états positifs et négatifs tendent à traiter de ces effets de manière indépendante et aucun ne formule de propositions concernant l’impact potentiel de ces leviers sur un état complet et unifié de santé psychologique au travail (e.g., Job Demand-Control(-Support) de Karasek & Theorell, 1990; Job Demands-Resources de Bakker & Demerouti, 2007). En considérant l’aspect interrelié et distinct de la facette positive et négative de la santé psychologique au travail, la présente thèse vise donc à explorer la dynamique entre les demandes, les ressources et un état complet et unifié de santé psychologique au travail. Pour ce faire, un article théorique et un article empirique sont présentés. L’article théorique intègre différentes théories afin d’apporter un éclairage sur l’incidence des demandes et ressources au travail sur un état complet et unifié de santé psychologique au travail, et d’expliquer simultanément l’influence de ces aspects du travail sur les facettes de bien-être et de détresse au travail. Il avance ainsi que, telles que définies par le modèle Job Demand-Resources (Bakker & Demerouti, 2007), les demandes tendraient a davantage représenter des menaces que des défis et auraient alors des effets néfastes sur un état complet de santé psychologique au travail et ses facettes positifs et négatifs. D’autre part, il est suggéré que lorsque les demandes sont élevées, avoir suffisamment de ressources pour se sentir capable de répondre avec succès aux demandes pourrait amener celles-ci à moins représenter des menaces et davantage représenter des défis. Comparativement à une situation où les ressources sont insuffisantes, cette première situation accroîtrait un état complet de santé psychologique au travail, de même que l’intensité de son volet positif, tandis que l’intensité de son volet négatif serait amoindrie. Enfin, il est suggéré que les ressources au travail faciliteraient la satisfaction des besoins psychologiques fondamentaux, ce qui aurait un effet bénéfique sur un état complet de santé psychologique au travail, de même que sur ses facettes. Pour sa part, l’article empirique vise à explorer empiriquement la dynamique entre les demandes, ressources et un état unifié et complet de santé psychologique au travail. Pour ce faire, deux études utilisant des modélisations par équations structurelles sont effectuées. La première utilise un devis transversal et deux échantillons de 302 et 384 enseignants. Elle montre que les demandes et ressources au travail ont une incidence directe respectivement nocive et bénéfique sur la santé psychologique au travail. Cependant, contrairement à ce qui était attendu, les ressources au travail n’auraient pas d’effet modérateur. Ces résultats sont similaires d’un échantillon à l’autre. La seconde étude utilise un devis longitudinal, deux temps de mesure avec une année d’intervalle et un échantillon de 158 enseignants. Suite à une comparaison des relations de causalité normale, inverse et réciproque; elle démontre que la causalité normale serait le type de relation qui expliquerait le mieux les données. Ce constat vient donc renforcer les résultats de l’étude précédente et suggère qu’une diminution des demandes et une augmentation des ressources s’accompagneraient d’une augmentation de la santé psychologique au travail. En explorant théoriquement et empiriquement la dynamique entre les demandes, les ressources et la santé psychologique au travail, la présente thèse offre des bases théoriques novatrices et des bases empiriques solides pour les recherches traitant de demandes et de ressources au travail qui désire étudier un état complet et unifié de santé psychologique au travail, et considérer l’aspect distinct et interdépendant de ses facettes positives et négatives. En pratique, une telle approche permettrait aux décideurs de plus facilement identifier les leviers sur lesquels il importe d’investir pour maximiser la santé psychologique, car cette dernière serait représentée par un critère unique plutôt que plusieurs critères séparés (Mihalopoulos, Carter, Pirkis, & Vos, 2013).

Is there an inverted U-shape relationship between job demands and work engagement : the moderating role of social support

Purpose - The purpose of this paper is to examine the possibility of an inverted U-shaped relationship between job demands and work engagement, and whether social support moderates this relationship. Design/methodology/approach – This study uses 307 technical and information technology (IT) managers who responded to an online survey. Multiple regressions are employed to examine linear and curvilinear relationship among variables. Findings – Overall, results support the applicability of the quadratic effect of job demands on employee engagement. However, only supervisor support, not colleague support, moderated the relationship between job demands and work engagement. Originality/value – The paper is the first to shed light on the quadratic effect of job demands on work engagement. The findings have noteworthy implications for managers to design optimal job demands that increase employee engagement.

Australia lawyer well-being : workplace demands, resources and the impact of time-billing targets

The purpose of the present study was to examine the types of workplace demands and resources experienced by full-time Australian lawyers, and the prevalence of a range of psychological outcomes. The study further focussed on the impact of time-billing targets on lawyers’ experience of these variables. Participants were 384 full-time Australian lawyers who completed an online questionnaire distributed by their Australian State or Territory Law Society. Analysis revealed that emphasis on profits within the workplace was the highest perceived demand, and the perception of social value in their work was the highest available resource. The results indicated that 37% of participants displayed Moderate to Extremely Severe depressive symptoms, and 35% were a positive screen for hazardous or harmful drinking. A series of three multivariate analyses of variance revealed significant differences between non-billers, low-to-moderate billers and high billers, with high billers experiencing greater demands, fewer resources and poorer psychological outcomes. The practical applications of these results for the legal profession are discussed.
