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.

The aim of this study was to investigate the measurement invariance of the Burnout Assessment Tool (BAT) across seven cross-national representative samples. In this study, burnout was modeled as a second-order factor in line with the conceptual definition as a syndrome. The combined sample consisted of 10,138 participants from countries in Europe and Japan. The data were treated as ordered categorical in nature and a series of models were tested to find evidence for invariance. Specifically, theta parameterization was used in conjunction with the weighted least squares (mean- and variance adjusted) estimation method. The results showed supportive evidence that BAT-assessed burnout was invariant across the samples, so that cross-country comparison would be justifiable. Comparison of effect sizes of the latent means between countries showed that Japan had a significantly higher score on overall burnout and all the first-order factors compared to the European countries. The European countries all scored similarly on overall burnout with no significant difference but for some minor differences in first-order factors between some of the European countries. All in all, the analyses of the data provided evidence that the BAT is invariant across the countries for meaningful comparisons of burnout scores.

Burnout is generally acknowledged by researchers, clinicians, and the public as a pervasive occupational difficulty. Despite this widespread recognition, longstanding debates remain within the scientific community regarding its definition and the appropriateness of classifying burnout as its own pathological entity. The current review seeks to address whether burnout should (or could) be characterized as a distinctive mental disorder to shed light on this debate. After briefly reviewing the history, theoretical underpinnings, and measurement of burnout, we more systematically consider the current evidence for and against its classification as a mental disorder within existing diagnostic systems. Stemming from a lack of conceptual clarity, the current state of burnout research remains, unfortunately, largely circular and riddled with measurement issues. As a result, information regarding the unique biopsychosocial etiology, diagnostic features, differential diagnostic criteria, and prevalence rates of burnout are still lacking. Therefore, we conclude that it would be inappropriate, if not premature, to introduce burnout as a distinct mental disorder within any existing diagnostic classification system. We argue, however, that it would be equally premature to discard burnout as a psychologically relevant phenomenon and that current evidence does support its relevance as an important occupational syndrome. We finally offer several avenues for future research, calling for cross-national collaboration to clarify conceptual and measurement issues while avoiding the reification of outdated definitions. In doing so, we hope that it one day becomes possible to more systematically re-assess the relevance of burnout as a distinctive diagnostic category.

This study sought to investigate the measurement properties of a “gold standard” instrument for measuring burnout, the Maslach Burnout Inventory – General Survey (MBI-GS), with a systematic literature review and meta-analysis of studies that had as the primary aim its psychometric validation. The search spanned from January 1996 to December 2022 using the following databases: Web of Science, Scopus, PubMed, APA PsychINFO, ScienceDirect, and ProQuest Dissertations and Theses Global. Our search identified 35 eligible studies for inclusion in the systematic review. Of these, 17 were included in the meta-analysis. The meta-analysis of the original 16-item version studies supported a three-dimensional representation of burnout with modest internal consistencies. However, similar to the narrative findings, it also indicated the viability of a two-factor solution. Consequently, the structural validity of the MBI-GS remains unclear, and so does its cross-cultural validity. The criterion validity of the cynicism and personal efficacy scales also raised a few questions. Overall, the findings provided some support for the adequacy of the measurement properties of the MBI-GS as a research tool measuring exhaustion, cynicism, and professional efficacy. However, we also identified challenges and practices of which researchers should be cognisant and that they should consider in future burnout projects.

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. A quantitative survey design was followed. Participants constituted a longitudinal sample of 370 participants, at three time points, after attrition. Descriptive statistics and structural equation modeling methods were implemented. 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. The results provided supportive evidence for an "indirect-only" mediation effect, for burnout's causal mediation mechanism in the health impairment process between work overload and psychological ill-health symptoms.
