The utility of the job demand-control-support (JDCS) model for explaining psychological and physical well-being has been documented in a variety of settings. The current study's purpose was to assess the effectiveness of the JDCS model for predicting occupational safety well-being criteria (i.e., workplace injuries) based on two studies that employed samples of union blue-collar workers from two different regions of the United States. The JDCS model's buffer hypotheses were evaluated using hierarchical linear modeling. Both studies showed significant interactions between situational constraints and safety control to predict workplace injuries such that safety control buffered the negative effects of situational constraints. No significant three-way interaction between situational constraints, safety control, and safety climate on workplace injuries was found for either study. The implications of the present findings for both the JDCS model and occupational safety research are discussed.
工作需求-控制-支持（JDCS）模型在解释心理和身体健康方面的效用已在各种环境中得到证实。本研究的目的是基于两项研究评估JDCS模型预测职业安全健康标准（即工作场所伤害）的有效性，这两项研究采用了来自美国两个不同地区的工会蓝领工人样本。使用分层线性模型评估了JDCS模型的缓冲假设。两项研究均显示，情境约束与安全控制之间存在显著的交互作用，可预测工作场所伤害，即安全控制缓冲了情境约束的负面影响。两项研究均未发现情境约束、安全控制和安全氛围对工作场所伤害存在显著的三方交互作用。本文讨论了这些研究结果对JDCS模型和职业安全研究的意义。
