Abstract
Objectives. Most research studying the relationship between job stress and chronic pain has relied on physiological responses. This study aims to determine psychosocial mechanisms by which job stress can influence chronic pain in workers. Methods. This cross-sectional study was carried out among 793 workers in gas and oil platforms or petroleum refinery plants in southern Iran. Structural equation modelling was applied to evaluate direct, indirect and total effects of job stress on chronic pain in the presence of mediating variables (work–family conflict and depression). Results. Job stress (B = 0.024, β = 0.477), 95% confidence interval (CI) [0.016, 0.032], work–family conflict (B = 0.031, β = 0.446), 95% CI [0.023, 0.038], depression (B = 0.046, β = 0.224), 95% CI [0.028, 0.064] and work experience (B = 0.083, β = 0.380), 95% CI [0.065, 0.101] had significant direct effects on chronic pain. Indirect paths from job stress to chronic pain via depression (B = 0.002, β = 0.042), 95% CI [0.001, 0.003] and work–family conflict (B = 0.004, β = 0.085), 95% CI [0.003, 0.006] were significant. Conclusions. Given that depression and work–family conflict mediate the effects of job stress on pain, stress management programmes for workers might include various strategies to reduce negative thoughts as well as cognitive biases and minimize role conflicts between work and private life.
