Abstract:
Objective To analyze the status of occupational stress in different types of train drivers . Methods By using cluster sampling method , a cross-sectional study was conducted in 1 339 train drivers (including 289 passenger train drivers, 637 freight trains drivers,339 passenger shunting train drivers ,and 74 high speed rail drivers ) from a Railway Bureau depot.The survey included individual factors , occupational stress factors , stress response factors and stress mitigating factors.The occupational stress factors, stress response factors and mitigating factors were measured by the revised effort-reward imbalance (ERI) model questionnaires and occupational stress measurement scale.By using the method of covariance analysized the difference of occupational stress factors of all types train drivers , the method of Stepwise regression was used to analyze the effection ( R2 ) of occupational stress factors and stress mitigating factors on stress response factors .Results Covariance analysis as covariates in age , education level , length of service and marital status showed that the scores of ERI ( 1.58 ±0.05 ) , extrinsic effort ( 19.88 ±0.44 ) , rewards (23.43 ±0.43), intrinsic effort (17.86 ±0.36), physical environment (5.70 ±0.22), social support (30.51 ±0.88)and daily tension (10.27 ±0.38 ) of high speed rail drivers were higher than other drivers (F values were 6.06, 11.32, 7.05, 13.25, 5.20, 9.48 and 6.14 respectively,P<0.01), but the scores of emotional balance (4.15 ±0.31) and positive emotion (2.06 ±0.20) were lower than other drives ( P<0.01 );the scores of psychological needs ( 10.48 ±0.18 ) , emotional balance ( 4.88 ±0.16 ) and positive emotion (2.63 ±0.10) of passenger train drivers were higher than other drivers (F values were 4.33 and 5.50 respectively, P<0.01).The descending rank of the effect value on occupational stress factors and mitigating factors to depressive symptoms of train drivers was high speed rail drivers (R2 =0.64), passenger train drivers ( R2 =0.44 ) , passenger shunting train drivers ( R2 =0.39 ) , freight trains drivers ( R2 =0.38);job satisfaction of train drivers was high speed rail drivers (R2 =0.68), passenger train drivers (R2 =0.62), freight trains drivers(R2 =0.43), passenger shunting train drivers(R2 =0.38); to daily tension of train drivers was high speed rail drivers ( R2 =0.54 ) , passenger train drivers ( R2 =0.37 ) , passenger shunting train drivers(R2 =0.33), freight trains drivers(R2 =0.30); emotional balance of train drivers was high speed rail drivers ( R2 =0.47 ) , passenger train drivers ( R2 =0.43 ) , passenger shunting train drivers(R2 =0.33), freight trains drivers(R2 =0.31).Conclusion ERI, psychological needs, work responsibilities , job roles , work conflict , and physical environment were important occupational stress factors of train drivers;social support was pivotal mitigating factors;different train drivers had different occupational stress status , high speed rail drivers were the highest , and freight trains drivers passenger train drivers or passenger shunting train drivers were the lowest .
