Hair cortisol concentrations (HCCs) are a potential physiological indicator of work related stress. However, studies that tested the relationship between HCC and self-reported stress in a work setting show mixed findings. This may be because few studies used worker samples that experience prolonged stress. Therefore, we compared a high workload sample (n = 81) and a normal workload sample (n = 91) and studied whether HCC was related to: (i) high job demands, low control, and low social support (JDCS model), and (ii) high effort, low reward, and high overcommitment (ERI model). Results showed that self-reported stress related to HCC only in the high workload sample and only for the variables of the ERI model. We found that HCC was higher when effort was high, reward low, and overcommitment high. An implication of this study is that a certain stress threshold may need to be reached to detect a relationship between self-reported stress and physiological measures such as HCC.
头发皮质醇浓度 (HCC) 是工作相关压力的潜在生理指标。然而，在工作环境中测试 HCC 与自我报告压力之间关系的研究得出的结果喜忧参半。这可能是因为很少有研究使用经历长期压力的工人样本。因此，我们比较了高工作量样本 (n=81) 和正常工作量样本 (n=91)，并研究了 HCC 是否与以下因素有关：(i) 高工作要求、低控制和低社会支持 (JDCS 模型)，以及 (ii) 高努力、低回报和高过度投入 (ERI 模型)。结果表明，只有在高工作量样本中，自我报告的压力才与 HCC 相关，而且仅与 ERI 模型的变量相关。我们发现，当努力程度高、回报低且过度投入高时，HCC 会更高。这项研究的一个含义是，可能需要达到一定的压力阈值才能检测到自我报告的压力与生理测量（如 HCC）之间的关系。
