Studies investigating differences in mental health problems between self-employed and employed workers have provided contradictory results. Many of the studies utilized scales validated for employed workers, without collecting validity evidence for making comparisons with self-employed. The aim of this study was to collect validity evidence for three different scales assessing depressive symptoms, emotional exhaustion, and sleep disturbances for employed workers, and combinators; and to test if these groups differed. We first conducted approximate measurement invariance analysis and found that all scales (...) were invariant at the scalar level. Self-employed workers had least mental health problems and employed workers had most, but differences were small. Though we found the scales invariant, we do not find them optimal for comparison of means. To be more precise in describing differences between groups, we recommend using clinical cut-offs or scales developed with the specific purpose of assessing mental health problems at work. (shrink)

The COVID-19 pandemic has altered workers' possibilities to combine work and private life. Work and private life could either interfere with each other, that is, when conflicting demands arise, or enrich, that is, when the two roles are beneficial to one another. Analyzing data from the Swedish Longitudinal Occupational Survey of Health through individual growth models, we investigated time trends of interference and enrichment between work and private life from 2016 through March to September 2020, which is during the first (...) wave of the pandemic. The sample included workers who had remained in the same workplace throughout the study period and worked at least 30% of full time, reaching 5,465 individuals. In addition, we examined trends in level of interference and enrichment across gender and industries. Results showed that Life-to-work interference increased over time in the Swedish working population, but neither did work-to-life interference nor enrichment. We observed only marginal differences across gender. Also, in the industries of fine manufacturing and real-estate activities, a decrease in interference, work-to-life interference, and life-to-work interference, respectively, was observed. In the human health and social care industry, an increase in interference and life-to-work interference was seen. Our conclusion is that overall changes to the possibilities to balance work and private life have occurred for workers in Sweden during the first period of the pandemic. Further studies are needed to study development time trends throughout the pandemic and across different occupations. (shrink)
