The Ways of Coping Questionnaire (WCQ) is a widely used measure of coping processes. Despite its use in a variety of populations, there has been concern about the stability and structure of the WCQ across different populations. This study examines the factor structure of the WCQ in a large sample of individuals diagnosed with fibromyalgia. The participants were 501 adults (478 women) who were part of a larger intervention study. Participants completed the WCQ at their 6-month assessment. Foundational factoring approaches were performed on the data (i.e., maximum likelihood factoring [MLF], iterative principal factoring [IPF], principal axis factoring (PAF), and principal components factoring [PCF]) with oblique oblimin rotation. Various criteria were evaluated to determine the number of factors to be extracted, including Kaiser's rule, Scree plot visual analysis, 5 and 10% unique variance explained, 70 and 80% communal variance explained, and Horn's parallel analysis (PA). It was concluded that the 4-factor PAF solution was the preferable solution, based on PA extraction and the fact that this solution minimizes nonvocality and multivocality. The present study highlights the need for more research focused on defining the limits of the WCQ and the degree to which population-specific and context-specific subscale adjustments are needed.
应对方式问卷（WCQ）是一种广泛用于测量应对过程的工具。尽管它在各种人群中都有应用，但人们一直担心WCQ在不同人群中的稳定性和结构。本研究考察了WCQ在大量被诊断为纤维肌痛的个体样本中的因子结构。参与者为501名成年人（478名女性），他们是一项更大规模干预研究的一部分。参与者在6个月评估时完成了WCQ。对数据进行了基本的因子分析方法（即最大似然因子分析[MLF]、迭代主因子分析[IPF]、主轴因子分析[PAF]和主成分因子分析[PCF]），并采用斜交oblimin旋转。评估了各种标准以确定要提取的因子数量，包括凯泽法则、碎石图视觉分析、解释5%和10%的独特方差、解释70%和80%的共同方差以及霍恩平行分析（PA）。基于PA提取以及该解决方案将非单义性和多义性降至最低这一事实，得出4因子PAF解决方案是更优解决方案的结论。本研究强调需要进行更多研究，重点是确定WCQ的局限性以及针对特定人群和特定情境的子量表调整的必要性程度。
