Dataset for: The Perceived Occupational Stress scale: A brief tool for measuring workers’ perception of stress at work

This article aims to present the development and test the psychometric properties of the Perceived Occupational Stress (POS) scale, a new brief instrument aimed at rating a worker’s perception of feeling stressed at work. Six studies are conducted on an overall sample of 1,805 Italian workers, to examine both the construct and concurrent validity of the POS scale. The results demonstrate the high internal consistency (α = .82) and test-retest reliability (r = .86) of the POS scale, as well as its structural validity and concurrent validity with the Maslach Burnout Inventory (r = .68 with Emotional Exhaustion) and the Effort-Reward Imbalance Questionnaire (r = .62 with Imbalance and r = .51 with Overcommitment). Moreover, the POS scale is determined to uniquely contribute toward predicting stress-related health complaints, over and above indicators of workplace stressors, as measured by the Health and Safety Executive Management Standards Indicator Tool (R2change = .06). Overall, the present findings indicate that the POS scale is a valid and reliable instrument for self-reporting occupational stress levels, and it could be used together with existing risk assessment measures of stress, to obtain a comprehensive evaluation of work-related stress.

本研究旨在介绍职业感知压力量表（Perceived Occupational Stress, POS）的编制过程，并检验其心理测量学属性。该量表为一款简洁的新型工具，用于评估员工对工作压力感受的自我感知。本研究针对1805名意大利劳动者组成的总样本开展六项子研究，以检验该量表的结构效度与效标关联效度。研究结果显示，POS量表具有良好的内部一致性（克朗巴赫α系数=0.82）与重测信度（相关系数r=0.86），同时具备优异的结构效度与效标关联效度：与马氏工作倦怠量表（Maslach Burnout Inventory）的情绪衰竭维度相关系数r=0.68，与付出-回报失衡问卷（Effort-Reward Imbalance Questionnaire）的失衡程度维度相关系数r=0.62、过度投入维度相关系数r=0.51。此外，相较于由健康与安全执行局管理标准指示工具（Health and Safety Executive Management Standards Indicator Tool）测得的工作场所压力源指标，POS量表在预测压力相关健康问题方面具有独特的增量预测效力（ΔR²=0.06）。综上，本研究结果表明，POS量表是一款可靠且有效的职业压力水平自我报告工具，可与现有的压力风险评估工具结合使用，以实现对工作相关压力的全面评估。
