This study among 528 South African employees working in the construction industry examined the dimensionality of burnout and work engagement, using the Maslach Burnout Inventory-General Survey, the Oldenburg Burnout Inventory, and the Utrecht Work Engagement Scale. On the basis of the literature, we predicted that cynicism and dedication are opposite ends of one underlying attitude dimension (called "identification"), and that exhaustion and vigor are opposite ends of one "energy" dimension. Confirmatory factor analyses showed that while the attitude constructs represent opposite ends of one continuum, the energy constructs do not-although they are highly correlated. These findings are also supported by the pattern of relationships between burnout and work engagement on the one hand, and predictors (i.e., work pressure, autonomy) and outcomes (i.e., organizational commitment, mental health) on the other hand. Implications for the measurement and conceptualization of burnout and work engagement are discussed.

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.

This study investigated the relationships between student burnout, intention to drop out, and satisfaction with studies, considering their self-reported social support from parents and significant others. First-year black African students from a peri-urban South African university campus (n = 452; females = 58.63%; mean age = 20.08 years, SD = 2.70 years) completed burnout, intention to drop out, satisfaction with studies, and social support measures. Regression analyses showed students with higher burnout symptoms (i.e. exhaustion, cynicism, and lack of professional efficacy) to have a higher intention to drop out from university and to be less satisfied with their studies. Social support from parents and significant others moderated certain relationships between burnout, intention to drop out, and satisfaction with studies. Understanding the role of social support on quality of student life could assist academic development and support services to provide better-targeted interventions with first-year university students.

The aims of this study were to investigate the construct validity, construct equivalence and reliability of a measuring instrument of job demands and resources, and to assess the differences between the job demands and resources in different organisations in South Africa. Stratified, random samples (N = 2717) of employees in different organizations were taken. Five reliable factors were extracted using principal component analysis with a varimax rotation, namely overload, growth opportunities, organisational support, advancement, and job insecurity. All factors, except organisational support, showed acceptable equivalence for different organisations. Statistically significant differences were found between the perceptions of job demands and resources in different organisations.
