Musculoskeletal disorders (MSDs) are a major health problem in the world. Self-reported questionnaires are a known method for estimating the prevalence of MSDs among the population. One of the studies concerning MSDs and their relation to work-related physical and psychosocial factors, as well as non-work-related factors, is the MUSIC-Norrtalje study in Sweden. In this study, the research group developed a questionnaire, which has been validated during its development process and is now considered a well-known instrument. The aim of this study is to validate the Persian version of this questionnaire.
The first step was to establish two expert panel groups in Iran and Sweden. The Focus Group Discussion (FGD) method was used to detect questionnaire face and content validity. To detect questionnaire reliability, we used the test-retest method.
Except for two items, all other questions that respondents had problems with in the focus group (20 of 297), had unclear translations; the ambiguity was related to the stem of the questions and the predicted answers were clear for the participants. The concepts of 'household/spare time' and 'physical activity in the workplace' were not understood by the participants of FGD; this has been solved by adding further descriptions to these phrases in the translation. In the test-retest study, the reliability coefficient was relatively high in most items (only 5 items out of 297 had an ICC or kappa below 0.7).
The findings from the present study provide evidence that the Persian version of the MUSIC questionnaire is a reliable and valid instrument.
肌肉骨骼疾病（MSDs）是全球主要的健康问题。自我报告问卷是估计人群中MSDs患病率的一种已知方法。瑞典的MUSIC - Norrtalje研究是一项关于MSDs及其与工作相关的身体和心理社会因素以及非工作相关因素关系的研究。在这项研究中，研究小组开发了一份问卷，该问卷在开发过程中已经过验证，现在被认为是一种知名工具。本研究的目的是验证该问卷的波斯语版本。
第一步是在伊朗和瑞典成立两个专家小组。采用焦点小组讨论（FGD）方法来检测问卷的表面效度和内容效度。为检测问卷的信度，我们使用了重测法。
除两项外，焦点小组中受访者有问题的所有其他问题（297项中的20项）翻译都不清晰；歧义与问题的题干有关，而参与者对预测答案很清楚。FGD的参与者不理解“家庭/业余时间”和“工作场所的身体活动”的概念；这已通过在翻译中对这些短语添加进一步描述来解决。在重测研究中，大多数项目的信度系数相对较高（297项中只有5项的组内相关系数（ICC）或kappa低于0.7）。
本研究结果提供了证据，表明MUSIC问卷的波斯语版本是一种可靠且有效的工具。
