CFI comparative fit index; RMSEA root mean square error of approximation; TLI Tucker-Lewis index; WFC work-family conflict; A1 deciding how to do the work; A2 deciding what to do at work; D1 having to work very fast; D2 having to work very intensively; D3 work demanding too much effort; D4 having enough time to do everything; D5 work involving conflicting demands; S1 learning new things through work; S2 work demanding a high level of expertise; S3 job requiring initiative; WFC1 time-based interference of work with family; WFC2 strain-based interference of work with family; WFC3 lacking time for personal care and leisure due to family and work demands
^aThe model was also adjusted by age, education, and sex
^bIn line with previous findings, the item repetitive work (skill discretion) was excluded and an error correlation between D1 and D2 (psychological job demands) was included
