  1. Note. Model 1 had seven domains and 59 questions and was based on Bekiari et al. [11]. Model 2 had six domains (excluding work environment) and 50 questions and was based on Eltayeb et al. [2]. Model 3 had six domains (excluding work environment) and 41 questions (nine questions excluded: one from work station, five from body posture, two from break time, and one from social support).
  2. *CAIC: consistent with the Akaike information criterion.
  3. **RMSEA: root mean square error of approximation; “90% CI” = 90% confidence interval for RMSEA.
  4. ***NNFI: non-normed fit index.
  5. £CFI: comparative fit index.
  6. ψGFI: goodness-of-fit index.
  7. &ECVI: expected cross-validation index and 90% CI.
