Two studies evaluated the psychometric properties and the latent structure of the Portuguese version of the Penn State Worry Questionnaire (PSWQ) in a large Brazilian college student sample. Results indicated that PSWQ had an adequate internal consistency. Exploratory factor analyses yielded a two-factor solution. One factor was related to the worry presence and incorporated all the non-reversed items. The other factor was associated to worry absence and incorporated all the reversed items. Confirmatory factor analysis leaded to a three-factor solution. One factor included all the PSWQ items whereas the two other factors were linked to the reversed and non-reversed worded items. Correlations coefficients of these two reversed and non-reversed factors with the total scores of the PSWQ and the trait form of the State-Trait Anxiety Inventory suggest that PSWQ has a single meaningful construct.
两项研究评估了宾夕法尼亚州担忧问卷（PSWQ）葡萄牙语版本在一个大型巴西大学生样本中的心理测量学特性和潜在结构。结果表明，PSWQ 具有足够的内部一致性。探索性因素分析得出了两因素解决方案。一个因素与担忧的存在有关，包含所有非反向项目。另一个因素与担忧的不存在有关，包含所有反向项目。验证性因素分析导致了三因素解决方案。一个因素包含了所有 PSWQ 项目，而另外两个因素则与反向和非反向的措辞项目有关。这两个反向和非反向因素与 PSWQ 总分和状态-特质焦虑量表特质形式的相关系数表明，PSWQ 具有单一有意义的结构。
