Studies which support the assumption that an "arthritis personality" is a causative factor in the development of rheumatoid arthritis are methodologically inadequate. Some are mere descriptions; others use inappropriate control groups. The investigations also suffer from failure to provide information on patients' characteristics, such as socioeconomic status and disease parameters. Although the quality of investigations concerning the etiological role of stress in the onset of rheumatoid arthritis has also been reduced by theoretical and measuring difficulties, the evidence supports an influence of stressful events. Results of controlled studies mostly refer to a comparison of group means. An own investigation shows that correlation studies are able to describe differences between groups, even if the groups do not differ significantly in their means.
支持“关节炎性格”是类风湿关节炎发病的一个致病因素这一假设的研究在方法上存在不足。有些研究仅仅是描述性的；其他研究则使用了不恰当的对照组。这些调查还存在未能提供患者特征信息的问题，比如社会经济地位和疾病参数。尽管关于压力在类风湿关节炎发病中的病因学作用的研究质量也因理论和测量方面的困难而有所下降，但证据支持压力事件的影响。对照研究的结果大多是关于组均值的比较。一项自身的调查表明，相关性研究能够描述组间差异，即使这些组在均值上没有显著差异。
