Employment insecurity and workplace injustice are important psychosocial hazards. However, few studies of these associations have been conducted in Chinese-speaking populations.
This study evaluated the psychometric properties of a Chinese version of employment insecurity and workplace justice scales, and examined their associations with the levels of workers' burnout status in Taiwanese workers.
Study subjects were participants in a national survey of employees in Taiwan, consisting of 9,636 men and 7,406 women. A self-administered questionnaire was used to assess employment insecurity (six items) and workplace justice (nine items), as well as other psychosocial work characteristics. After the survey was completed, in-depth interviews with 10 employees were conducted for a qualitative evaluation.
Cronbach's α was 0.87 or greater for the workplace justice scale and 0.76 or greater for the employment insecurity scale, indicating satisfactory internal consistencies. Exploratory factor analyses revealed a factor pattern consistent with the theoretically assumed structure, except that the items with statements in reversed direction were loaded on separated factors. Higher levels of employment insecurity and lower levels of workplace justice were associated with higher burnout scores. However, results from the qualitative interviews suggested that some questionnaire items contained double-barreled questions, and some questions were misinterpreted or considered irrelevant by participants.
The Chinese version of employment insecurity and workplace justice scales were found to have satisfactory reliability and validity. However, improvement of these scales is still needed.
就业不安和工作场所不公正都是重要的社会心理危害。然而，在华语人群中，很少有研究这些关联。
本研究评估了就业不安和工作场所公正量表的中文版本的心理测量特性，并考察了它们与台湾工人工作倦怠水平的关联。
研究对象是台湾一项员工全国调查的参与者，包括 9636 名男性和 7406 名女性。采用自我管理问卷评估就业不安（六项）和工作场所公正（九项）以及其他社会心理工作特征。调查完成后，对 10 名员工进行了深入访谈，以进行定性评估。
工作场所公正量表的 Cronbach's α 为 0.87 或更高，就业不安量表的 Cronbach's α 为 0.76 或更高，表明内部一致性良好。探索性因素分析显示，除了以相反方向陈述的项目加载在分离的因子上外，因子模式与理论假设的结构一致。较高的就业不安和较低的工作场所公正与较高的倦怠得分相关。然而，定性访谈的结果表明，一些问卷项目包含双重问题，一些问题被参与者误解或认为不相关。
就业不安和工作场所公正量表的中文版本具有令人满意的可靠性和有效性。然而，这些量表仍需改进。
