This study examined the factor structure of the Injustice Experience Questionnaire (IEQ; Sullivan et al. in J Occup Rehabil 18:249-261, 2008) using confirmatory factor analysis (CFA). Two models were proposed for analysis: a single factor and a two-factor model.
A total of 150 participants (81 males and 69 females, mean age = 45.48 years, SD = 10.71), with a chronic work-related musculoskeletal disorder (53 % back condition), and a mean duration of work disability of 4.34 years (SD = 5.14), completed the IEQ and measures of depression and anger. CFA was performed on the IEQ data using the maximum likelihood estimation method.
Neither proposed model provided an acceptable fit; however, a good fitting model with two highly correlated factors and one error covariance was derived through post hoc model fitting. The two-factors were differentially correlated to depression and duration of work disability, but not anger.
The IEQ appears to be a useful tool to support the comprehensive psychosocial assessment of injured workers with long-term disability secondary to a musculoskeletal disorder. In addition to identifying perceived injustice, the IEQ may also be used to inform the choice of psychological interventions. The IEQ has construct validity and generalizability across different populations of injured workers.
本研究使用验证性因素分析（CFA）检验了不公正经历问卷（IEQ；沙利文等人，《职业康复杂志》，2008年，第18卷，第249 - 261页）的因素结构。提出了两个模型用于分析：单因素模型和双因素模型。
共有150名参与者（81名男性和69名女性，平均年龄 = 45.48岁，标准差 = 10.71），患有慢性工作相关肌肉骨骼疾病（53%为背部疾病），平均工作残疾时长为4.34年（标准差 = 5.14），完成了IEQ以及抑郁和愤怒测量。使用最大似然估计法对IEQ数据进行CFA分析。
两个提出的模型均未提供可接受的拟合度；然而，通过事后模型拟合得出了一个具有两个高度相关因素和一个误差协方差的良好拟合模型。这两个因素与抑郁和工作残疾时长存在差异相关性，但与愤怒无关。
IEQ似乎是一种有用的工具，可支持对因肌肉骨骼疾病导致长期残疾的受伤工人进行全面的社会心理评估。除了识别感知到的不公正之外，IEQ还可用于指导心理干预措施的选择。IEQ具有结构效度，并且在不同受伤工人群体中具有可推广性。
