We examined the moderating (buffering or amplifying) effect of psychosocial safety climate (PSC) on the association of job demands (psychological demands) and job resources (job control, supervisor support, coworker support, and extrinsic reward) with psychological distress among Japanese employees.
A self-report web-based questionnaire was administered to 2,200 employees (1,100 men and 1,100 women) registered with a Japanese private online survey company. The questionnaire included scales on job demands and job resources (the Job Content Questionnaire and the short-form Effort-Reward Imbalance Questionnaire), PSC (the 12-item PSC scale), and psychological distress (the K6 scale) and items on participants' demographic and occupational characteristics (age, gender, education, occupation, work form, and working hours per week). Hierarchical multiple regression analyses were performed using psychological distress as a dependent variable. Interaction terms of job demands and job resources with PSC were included.
There was a significant interaction effect of psychological demands with PSC on psychological distress ( = -0.053, = 0.008), adjusted for demographic and occupational characteristics. simple slope analysis showed that the simple slope of psychological demands was lesser at higher levels of PSC (1 standard deviation above the mean) ( = 0.101, < 0.001) than at lower levels (1 standard deviation below the mean) ( = 0.199, < 0.001). No significant interactions were observed between job resources and PSC.
Our findings suggest that PSC buffers the positive association of psychological demands with psychological distress.
我们研究了心理社会安全氛围（PSC）对日本员工工作需求（心理需求）与工作资源（工作控制、上级支持、同事支持和外部奖励）与心理困扰之间关联的调节（缓冲或放大）作用。
对一家日本私人在线调查公司登记在册的2200名员工（1100名男性和1100名女性）进行了基于网络的自填式问卷调查。问卷包括工作需求和工作资源量表（工作内容问卷和简版努力-回报失衡问卷）、PSC量表（12项PSC量表）、心理困扰量表（K6量表）以及关于参与者人口统计学和职业特征（年龄、性别、教育程度、职业、工作形式和每周工作时长）的项目。以心理困扰为因变量进行分层多元回归分析。纳入了工作需求和工作资源与PSC的交互项。
在对人口统计学和职业特征进行调整后，心理需求与PSC对心理困扰存在显著交互效应（β = -0.053，p = 0.008）。简单斜率分析表明，在较高水平的PSC（高于均值1个标准差）时，心理需求的简单斜率（β = 0.101，p < 0.001）低于较低水平（低于均值1个标准差）时（β = 0.199，p < 0.00）。未观察到工作资源与PSC之间存在显著交互作用。
我们的研究结果表明，PSC缓冲了心理需求与心理困扰之间的正相关关系。
