A Confirmatory Investigation of a Job Demands-Resources Model Using a Categorical Estimator

A confirmatory investigation of a job demands-resources model was conducted with alternative methods, in a sample of 15, 633 working adults aggregated from various economic sectors. The proposed model is in line with job demands-resources theory and assumes two psychological processes at work which are collectively coined “the dual process.” The first process, the energetic, presents that job demands lead to ill-health outcomes due to burnout. The second process, the motivational, indicates that job resources lead to organizational commitment due to work engagement. Structural equation modelling analyses were implemented with a categorical estimator. Mediation analyses of each of the processes included bootstrapped indirect effects and kappa-squared values to apply qualitative labels to effect sizes. The relationship between job resources and organizational commitment was mediated by engagement with a large effect. The relationship between job demands and ill-health was mediated by burnout with a medium effect. The implications of the results for theory and practice were discussed.

Strengths use and deficit correction in organizations: development and validation of a questionnaire

Although the positive psychology tradition emphasizes the importance of a balanced approach regarding individual strengths and weaknesses, there is no valid instrument to measure these phenomena in organizations. The purpose of the present studies is to develop and validate an instrument that measures four dimensions, namely perceived organizational support (POS) for strengths use, POS for deficit correction, strengths use behaviour, and deficit correction behaviour. In study 1 and 2, the Strengths Use and Deficit COrrection (SUDCO) questionnaire was developed and tested for its factor structure, reliability, and convergent and criterion validity in two samples of South African employees (N = 338 and N = 361, respectively). In study 3, the convergent and criterion validity of the SUDCO were examined in a sample of Dutch engineers (N = 133). Results indicated that the intended dimensions of strengths use and deficit correction can be measured reliably with 24 items and showed convergent validity. Moreover, POS for strengths use and strengths use behaviour correlated positively with self- and manager-ratings of job performance, supporting the criterion validity of these scales. As expected, POS for deficit correction and deficit correction behaviour were unrelated to the performance ratings.

Organisational and individual strengths use as predictors of engagement and productivity

This study sought to determine whether Perceived Organisational Support for Strengths Use (POSSU) and Proactive Behaviour towards Strengths Use (PBSU) predict engagement and productivity in a sample of South African call centre operators. Participants were 218 call centre operators within the financial services sector (females=51%, males = 49%), representative of the South African population, and predominantly holding secondary educational qualifications. Information was gathered through a cross-sectional quantitative research design comprising self-report measures. The measures were administered on site within a call centre of one of the countrys largest financial service providers. Structural equation modelling methods were implemented to establish the model fit of the constructs in the study and to explain structural paths between the variables. Findings showed that POSSU and PBSU are significant predictors of work engagement. PBSU predicted productivity. In addition, engagement mediated the relationship between POSSU/PBSU and productivity. This supports the theoretical context of the job demands-resources (JD-R) model and provides grounds for further exploration of the strengths-based approach (on both organisational and individual levels) as a developmental approach to utilise within organisations to enhance engagement and productivity.

Work overload, burnout, and psychological ill-health symptoms: A three-wave mediation model of the employee health impairment process

ABSTRACT Background and Objectives: The study reported here investigated the causal relationships in the health impairment process of employee well-being, and the mediating role of burnout in the relationship between work overload and psychological ill-health symptoms, over time. The research is deemed important due to the need for longitudinal evidence of the health impairment process of employee well-being over three waves of data. Design: A quantitative survey design was followed. Participants constituted a longitudinal sample of 370 participants, at three time points, after attrition. Methods: Descriptive statistics and structural equation modeling methods were implemented. Results: Work overload at time one predicted burnout at time two, and burnout at time two predicted psychological ill-health symptoms at time three. Indirect effects were found between work overload time one and psychological ill-health symptoms time three via burnout time two, and also between burnout time one and psychological ill-health symptoms time three, via burnout time two. Conclusions: The results provided supportive evidence for an “indirect-only” mediation effect, for burnouts causal mediation mechanism in the health impairment process between work overload and psychological ill-health symptoms.

Job burnout’s relationship with sleep difficulties in the presence of control variables: a self-report study

Burnout, as a work-related phenomenon, has negative consequences on employee functioning and is well documented. What is deserving of further investigation is how effort-recovery processes may be affected, in this instance, sleep. The purpose of this study was to investigate whether significant sleep difficulties are reported when employees report experienced burnout, while also controlling for age, gender, exercise, smoking habits, and treatment for depression. A cross-sectional survey design was used in data collection. The sample consisted of 734 participants with white collar positions in the financial industry of South Africa. Structural equation modelling methods were implemented in order to investigate the hypotheses. The results of the structural model indicated that burnout was significantly related to sleep difficulties, even in the presence of reported treatment for depression, and the other control variables. The correlations between burnout, treatment for depression, as well as sleep difficulties were all positive and practically significant. The results, recommendations, limitations, and practical implications of the study are discussed.

Job Burnout, Work Engagement and Self-reported Treatment for Health Conditions in South Africa

The purpose of the study being reported here was to investigate the relationship of job burnout and work engagement with self-reported received treatment for health conditions (cardiovascular condition, high cholesterol, depression, diabetes, hypertension and irritable bowel syndrome), while controlling for age, gender, smoking and alcohol use. The sample comprised 7895 employees from a broad range of economic sectors in the South African working population. A cross-sectional survey design was used for the study. Structural equation modelling methods were implemented with a weighted least squares approach. The results showed that job burnout had a positive relationship with self-reported received treatment for depression, diabetes, hypertension and irritable bowel syndrome. Work engagement did not have any significant negative or positive relationships with the treatment for these health conditions. The results of this study make stakeholders aware of the relationship between job burnout, work engagement and self-reported treatment for health conditions. Evidence for increased reporting of treatment for ill-health conditions due to burnout was found. Therefore, attempts should be made to manage job burnout to prevent ill-health outcomes.

Job crafting and its impact on work engagement and job satisfaction in mining and manufacturing

The purpose of this study was to investigate job crafting and its relationship with work engagement and job satisfaction within the South African context. This research is important as job crafting has been shown to have a positive influence on employee motivation. A cross-sectional survey design was used to collect primary data from organisations in the mining and manufacturing industries of South Africa (N = 470). The results of multi-group structural equation modelling showed that the original four-factor structure of the job crafting scale was supported by the data, but that a three-factor structure was necessary due to a discriminant validity concern regarding two job crafting dimensions. Regression results revealed that increasing structural job resources with challenging job demands, and increasing social job resources were significant predictors of work engagement in both groups. Contrary to expectations decreasing hindering job demands was a negative predictor of job satisfaction in the mining group. Furthermore, increasing social job resources was also a significant predictor of job satisfaction in both groups. This study indicates the importance of job crafting for work engagement and job satisfaction in organisations.

Burnout, depressive symptoms, job demands and satisfaction with life: discriminant validity and explained variance

Burnout is considered an occupational health concern. The burnout–depression overlap is an important area of research as the foundations of burnout and its diagnostic value have come under increasing scrutiny, calling for burnout to not be classified as an independent disorder but rather as a subtype of depression. Furthermore, as burnout is defined as a work-specific syndrome, workplace factors have been argued to be the major indicators of burnout. Recent research however, calls this into question. This study seeks to establish the overlap between burnout and depressive symptoms and to determine if burnout is in fact a multi-domain phenomenon. A cross-sectional research design was used, a convenience sample of educators from the Gauteng province of South Africa was collected (N = 399). Confirmatory factor analysis was applied in a structural equation modelling framework. Discriminant validity analysis was conducted by investigating the average variance extracted and the shared variance between constructs. Finally, relative weight analysis was conducted to ascertain the unique contribution explained by the work-specific and general life domain factors. Results showed that burnout could be distinguished from depressive symptoms. Job demands, depressive symptoms, and satisfaction with life all explained significant amounts of variance in the burnout construct. Relative weight analysis revealed that emotional load and depressive symptoms explained equal amounts of variance in burnout, but that the aggregated work-specific factors explained the most variance in burnout. This study indicates that burnout is a multi-domain phenomenon and not isolated to the domain of work. Further research is needed in this regard.

Job insecurity, career opportunities, discrimination and turnover intention in post-apartheid South Africa: examples of informative hypothesis testing

The objective of this paper was to investigate differences in male employee experiences in the light of employment equity law and a strong affirmative action drive within present-day South African organizations. This research is important as it can substantiate or invalidate perspectives and beliefs surrounding employment equity issues. A cross-sectional design was used which consisted of a stratified random sample from five corporate organizations (N = 1000). Latent variable modeling with Bayesian estimation was implemented. This paper also demonstrated the use of informative hypothesis testing and subsequent Bayes factors to directly compare the informative hypotheses, in order to show how much more likely one hypothesis is to be the correct hypothesis, compared to the other(s). The results revealed that non-designated (white male) employees experience more job insecurity than their designated (black male) counterparts, but this does not necessarily associate with more turnover intention. It was also found that when designated employees experience less career opportunities, they show more turnover intention. Furthermore, it was shown that designated employees perceive more discrimination, but that this does not associate with more turnover intention. The limitations and future research opportunities are discussed.

Exploring demands from the perspective of employees identified as being at risk of burnout

ABSTRACT Purpose: Burnout has become an occupational health concern. However, little is known about the experiences of individuals identified as being at risk of burnout. This study aimed to address this gap by exploring employees’ experiences of well-being who were identified as burnout risks. Method: Interviews were conducted with 26 employees who agreed to participate in the study. A phenomenological approach was taken, with a case study design as the research strategy. Results: Three major themes were identified: job demands, life demands, and health concerns. It was evident that participants were experiencing demanding conditions in both their work and personal lives, indicating burnout to be a multi-domain phenomenon. Conclusions: Professionals and managers should take note of these results to assist and support employees who are identified as being at risk of burnout.
