Table 8: Regression analysis of the mediating effect of job satisfaction. F = 4.263, \(p\) < 0.001), thereby validating Hypothesis H2 (\"Organizational climate is negatively correlated with unsafe behaviors\"). Model 9 in Table 10 examines the effect of anxiety psychology on safety competency after controlling for demographic variables (gender, career age, education level, work experience, and anxiety level). Model 10 introduces both anxiety psychology and safety competency (mediator) to assess their combined influence on unsafe behaviors. Model 11 evaluates the direct effect of safety competency (as the sole mediator) on unsafe behaviors while controlling for demographics. Model 9 revealed a significant negative correlation between anxiety psychology and safety competency (\(\beta=-0.346\), \(p\) < 0.01), validating Hypothesis H6 (\"Safety competency is negatively correlated with anxiety psychology\"). \begin{table}
