The Copenhagen Psychosocial Questionnaire (COPSOQ) is a widely used tool for evaluation of psychosocial risk factors at work. The aims of this study were to describe the short version of Farsi COPSOQ and to present its psychometric properties. A total of 427 administrative health care staff participated in this descriptive methodological study. Forward-backward procedure was adopted to translate the questionnaire from English into Farsi. Content validity was assessed by a panel of 10 experts. Construct validity was evaluated by exploratory and confirmatory factor analyses. The internal consistency and test-retest reliability were assessed using Cronbach's α and intraclass correlation coefficient(ICC), respectively. The feasibility was assessed using ceiling and floor effect. The short version of Farsi COPSOQ was configured with 16 dimensions (32 items).Content validity of the questionnaire was established. Factor analysis supported the conceptual multi-dimensionality (four factors), and therefore confirmed the construct validity of the Farsi COPSOQ. The internal consistency (Cronbach's α ranging between 0.75 and 0.89) and test retest reliability (ICC values ranged from 0.75 to 0.89) were both approved and the results showed no ceiling or floor effect. The results support the use of Farsi COPSOQ for evaluation of psychological risks and for research purposes in Iranian population.
哥本哈根心理社会问卷（COPSOQ）是一种广泛用于评估工作中心理社会风险因素的工具。本研究的目的是描述波斯语版COPSOQ的简短版本，并呈现其心理测量特性。共有427名行政医护人员参与了这项描述性方法学研究。采用前后翻译程序将问卷从英语翻译成波斯语。由10名专家组成的小组评估内容效度。通过探索性和验证性因素分析评估结构效度。分别使用克朗巴赫α系数和组内相关系数（ICC）评估内部一致性和重测信度。使用天花板效应和地板效应评估可行性。波斯语版COPSOQ简短版本由16个维度（32个项目）组成。问卷的内容效度得以确立。因素分析支持概念的多维性（四个因素），因此证实了波斯语版COPSOQ的结构效度。内部一致性（克朗巴赫α系数在0.75至0.89之间）和重测信度（ICC值在0.75至0.89之间）均得到认可，结果显示无天花板效应或地板效应。研究结果支持使用波斯语版COPSOQ评估伊朗人群的心理风险及用于研究目的。
