This study examined the longitudinal relationship between work–family interaction (WFI) in terms of the direction of influence (work-to-family vs. family-to-work) and type of effect (conflict vs. facilitation) and burnout. A sample of 2235 respondents from eight different occupational groups (lawyers, bus drivers, employees within information technology, physicians, teachers, church ministers, employees within advertisement, and nurses) supplied data at two points in time with a 2-year time interval. Building upon Hobfoll's (1989) Conservations of Resources (COR) theory, three causal models were proposed. The results of SEM-analyses revealed evidence for both a normal (WFI → burnout), a reverse (WFI ← burnout), and a reciprocal (WFI ↔ burnout) relationship. In general, there were lagged positive effects between the conflict dimensions of WFI and burnout and lagged negative effects between the facilitation dimension of WFI and burnout. One exception was a significant lagged negative effect between disengagement at Time 1 and work-to-family conflict at Time 2, suggesting that distancing oneself from job might act as a coping strategy causing lower levels of work-to-family conflict.

This longitudinal study examined the dynamic relationship between work engagement (vigour and dedication) and symptoms of anxiety and depression. A sample of 3475 respondents from eight different occupational groups (lawyers, physicians, nurses, teachers, church ministers, bus drivers, people working in advertising and people working in information technology) in Norway supplied data at two points in time with a 2‐year time interval. The advantages of longitudinal design were utilized, including testing of reversed causation and controlling for unmeasured third variables. In general, the results showed that the hypothesized normal causal relationship was superior to a reversed causation model. In other words, this study supported the assumption that work engagement is more likely to be the antecedent for symptoms of depression and anxiety than the outcome. In particular, the vigour facet of work engagement provides lower levels of depression and anxiety 2 years later. However, additional analyses modelling unmeasured third variables indicate that unknown third variables may have created some spurious effects on the pattern of the observed relationship. Implications of the findings are discussed in the paper. Copyright © 2011 John Wiley & Sons, Ltd.

The paper describes the study design, research questions and methods of a large, international intervention project aimed at improving employee mental health and well-being in SMEs and public organisations. The study is innovative in multiple ways. First, it goes beyond the current debate on whether individual- or organisational-level interventions are most effective in improving employee health and well-being and tests the cumulative effects of multilevel interventions, that is, interventions addressing individual, group, leader and organisational levels. Second, it tailors its interventions to address the aftermaths of the Covid-19 pandemic and develop suitable multilevel interventions for dealing with new ways of working. Third, it uses realist evaluation to explore and identify the working ingredients of and the conditions required for each level of intervention, and their outcomes. Finally, an economic evaluation will assess both the cost-effectiveness analysis and the affordability of the interventions from the employer perspective. The study integrates the training transfer and the organisational process evaluation literature to develop toolkits helping end-users to promote mental health and well-being in the workplace.

The Maslach Burnout Inventory-General Survey (MBI-GS) is designed to measure the three subdimensions (exhaustion, cynicism, and professional efficacy) of burnout in a wide range of occupations. This article examines the factorial validity of the MBI-GS across eight different occupational groups in Norway: lawyers, physicians, nurses, teachers, church ministers, bus drivers, and people working within advertising and information technology (N = 5,024). Separate confirmatory factor analyses using LISREL showed that the hypothesized three-factor model had sufficient fit in all occupational groups except for the group of people working in advertising. In a multigroup analysis including all occupations but the latter one and in an analysis of all individuals combined into one sample, the three-factor model had a clearly better fit than the alternative one-factor and two-factor models. The results support that MBI-GS provides a suitable measurement to assess burnout across a diversity of professions.

The aim of this study was twofold. The first intention was to examine the factorial validity of a work/family interaction in terms of the direction of influence (work-to-family vs. family-to-work) and type of effect (conflict vs. facilitation). Second, gender differences along these four dimensions of work/family interaction were explored. Data were obtained from eight different occupational groups in Norway: lawyers, physicians, nurses, teachers, church ministers, bus drivers, and people working in advertising and information technology (IT; N = 3,313). Multigroup analysis indicated that the hypothesized four-factor model clearly has a better fit than the alternative one-factor and two-factor models. Latent mean comparisons revealed significant gender differences along all the dimensions. Women reported more conflict and facilitation in both directions compared to men. Although there were some occupational differences, this was indicative of a more fluid boundary between work and family among women. The findings are discussed in an identity perspective.
About Me
I am professor in Occupational health psychology at the Department of Psychology and Director of Center for Health Promotion Research. I have a PhD from NTNU on the interaction between work and family.
I give lectures and teach in various fields such as occupational health, work environment, health promotion, intervention research and quantitative method.
I have initiated and developed, ARK, which is a comprehensive implementation program to promote psychosocial work environment in academia. Currently over 19 universities and university colleges in Norway (N>30.000), and two in Sweden, is using ARK regularly in their systematic health, work and safety effort.
In 2016/2017 I was awarded a Fulbright Scholarship to work one year at Interdisciplinary Center for Healthy Workplaces, UC Berkeley. This resulted in the project "Healthy workplaces", a collaboration project between NTNU, UC Berkeley and BI Campus Stavanger. I was the principal investigator (PI) for Norway, financed by Peder Sæther grant.
Currently I am the WP leader in the EU project "H-work - Multilevel Interventions to Promote Mental Health in SMEs and Public Workplaces". Together with 14 partners from nine different countries, we will develop and test interventions, measuring instruments, tools and models to promote mental health in Europe.
