Workstyle as it is related to symptoms of musculoskeletal symptoms of the upper limbs is the behavioural, cognitive and physical responses that occur in individuals to increases in work demands. A self report measure of this construct was developed that was both associated with and predictive of work related upper extremity symptoms. The aim of this study was to translate, culturally adapt, and validate a Chinese version of the Workstyle Short Form (C-WSF).
The C-WSF was translated following a forward and backward translation approach. Content validity was examined by item- and scale-level content validity indices. The intra-class correlation coefficient (ICC) was used to analyze test-retest reliability. Exploratory factor analysis was used to identify factor structures and the internal consistency of these factors was assessed by calculating Cronbach's alpha reliability coefficients. The construct validity of the C-WSF was first determined by convergence in relation to the Cumulative Symptoms Score for Upper Extremity symptoms and then by comparison of those with and without upper extremity pain in Chinese cooks, a work with a high level of exposures to varying levels of work demands coupled with exposure to workplace psychosocial and biomechanical stressors.
The C-WSF demonstrated excellent item- and scale-level content validity index (>0.9). The factor structure of C-WSF was similar to its original English version. The internal consistency of different subscales of C-WSF ranged from 0.65 to 0.91. The ICC was between 0.79 and 0.93 indicating good test-retest reliability. C-WSF was significantly correlated with upper extremity symptoms (r = 0.34, p < 0.001).
C-WSF is a reliable and valid version of the Workstyle measures for use in Chinese population.
与上肢肌肉骨骼症状相关的工作方式是个体对工作需求增加所产生的行为、认知和身体反应。已开发出一种对该结构的自我报告测量方法，它与工作相关的上肢症状相关且具有预测性。本研究的目的是翻译、文化调适并验证工作方式简表（C-WSF）的中文版。
C-WSF采用正向和反向翻译方法进行翻译。通过项目和量表层面的内容效度指标来检验内容效度。使用组内相关系数（ICC）分析重测信度。探索性因素分析用于识别因素结构，并通过计算克朗巴哈α信度系数来评估这些因素的内部一致性。C-WSF的结构效度首先通过与上肢症状累积症状评分的收敛性来确定，然后通过比较中国厨师（一项工作暴露于不同水平工作需求以及工作场所心理社会和生物力学应激源的职业）中有无上肢疼痛的情况来确定。
C-WSF在项目和量表层面均显示出优异的内容效度指标（>0.9）。C-WSF的因素结构与其原始英文版相似。C-WSF不同子量表的内部一致性范围为0.65至0.91。ICC在0.79至0.93之间，表明重测信度良好。C-WSF与上肢症状显著相关（r = 0.34，p < 0.001）。
C-WSF是适用于中国人群的可靠且有效的工作方式测量版本。
