  1. aModel fit indices recommended criteria: comparative fit index (CFI ≥0.90) [6], the standardized root mean square residual (SRMR < 0.08) & the Root Mean Square Error Of Approximation (RMSEA < 0.08) [7], Chi-square (Chi < 0.05) [8]
  2. bModel fit indices were examined for six of the 12 HSOPSC composites that had four items. SMEA: Supervisor/manager expectations and actions promoting safety
