压力研究人员在试图绕过相关性研究中的方法学问题时，求助于增加第二类错误可能性的分析技术。例如，认为压力在肠易激综合征中没有作用的研究与大量的临床经验不一致，可能是错误的。讨论了几个测量问题，但最重要的是调查人员处理慢性压力水平和症状的个体差异的方式。J.Suls及其同事在本期中建议，在估计压力和症状之间的关系之前，先纠正这些个体差异，但这是不合逻辑的，因为大多数压力源都是慢性的--它们与人们生活的社会和经济环境有关。大多数研究人员没有考虑到的一个更重要的困惑是，躯体化对压力评估和症状报告的贡献。
Stress researchers, in attempting to circumvent methodological problems in correlation studies, have resorted to analytical techniques that increase the likelihood of a Type II error. For instance, studies suggesting that stress plays no role in irritable bowel syndrome are at variance with a large body of clinical experience and may be in error. Several measurement issues are discussed, but the most significant concerns the way investigators deal with individual differences in chronic levels of stress and symptoms. J. Suls and colleagues, in this issue, recommend correcting for these individual differences before estimating the relationship between stress and symptoms, but this is illogical because most stressors are chronic—they are related to the social and economic circumstances in which people live. A more important confound, not considered by most investigators, is the contribution of somatization to stress assessment and symptom reports.
