Abstract:
Objective:To explore the influence of vibration operation on occupational psychological behavior of workers.Methods:From May to August 2021, a total of 384 workers from 20 factories in a city of Guangdong Province were selected as the research objects.According to the workers whether engaged in vibration operations, they were divided into the vibration group and the control group.There were 229 workers in the vibration group and 155 workers in the control group.The occupational stress scale, job burnout scale and job fatigue symptom scale were used for questionnaire survey, and IBM SPSS 24.0 software was used for statistical description and data analysis, and t-test was used for comparison of independent samples between the two groups, one-way ANOVA was used for comparison of means between multiple groups, and LSD test was used for further pin-pide comparison. Results:In the vibration group, the scores of cognitive behavioral stress(3.78±1.79), psychological stress response(4.15±2.29), physical stress(2.81±1.65) and total stress (10.74±5.11) were higher than those of the control group ((2.23±1.23), (2.30±1.62), (1.81±1.07), (6.34±2.88), t=9.31, 8.67, 6.68, 9.72, all P<0.01), and job burnout scale of emotional exhaustion (8.95±3.62), depersonalization (3.24±2.16) were higher than the control group ((5.37±2.72), (1.79±1.20), t=10.48, 7.59, both P<0.01). The score of personal achievement (26.20±2.47) was lower than that of control group ((29.73±2.52), t=13.64, P<0.01). In the job fatigue symptom scale of sleepiness (8.38±1.52), emotional restlessness (6.85±1.74), displeasure (6.38±1.57), sluggishness (8.94±2.05), visual fatigue (7.83±1.95), and total score (38.37±6.56) were higher than those of the control group ((7.89±1.29), (6.21±1.32), (5.61±1.29), (6.54±1.52), (6.67±2.02), (32.92±5.56), t=3.26, 3.90, 5.00, 12.45, 5.61, 8.48, all P<0.01)). There were significant differences in scores of occupational stress, occupational burnout and occupational fatigue symptom among different seniority groups (all P<0.01). The scores of occupational stress, job burnout and job fatigue symptoms of workers in 6-10 years and more than 10 years of service group were higher than those in 0-5 years of service group, and the differences were statistically significant ( P<0.05). Length of service was correlated with occupational stress, job burnout and job fatigue.There was a correlation between the scores of all dimensions and total score of the occupational stress scale and the scores of all dimensions of occupational burnout scale ( r=-0.67-0.63, P<0.01), as well as the scores of all dimensions and total score of the occupational fatigue symptom scale ( r=0.26-0.73, P<0.01). The direct effect of occupational stress on job fatigue was 0.417, and the mediating effect of occupational stress on job fatigue through job burnout was 0.127. Conclusion:Vibration work can lead to occupational stress, job burnout and job fatigue, which is an important factor affecting occupational psychology and occupational behavior.
