An investigation of a case of apparent mass psychogenic illness was undertaken in a midwestern electronics assembly plant. The plant employed 500 workers, of whom 80% were female. The illness outbreak involved a total of 90 female first shift workers who reported a variety of nonspecific symptoms such as headache, dizziness, and lightheadedness in response to a strange odor in the workplace. Although environmental testing revealed some localized concentrations of a few airbone contaminants, no environmental toxins were discovered that could account for the continuing outbreaks of illness. An ad hoc sample of affected and nonaffected workers was surveyed to assess the influence of psychological, sociological, and work environment factors in the outbreak. Analysis of the data revealed that affected workers reported more physical discomfort (temperature variations, poor lighting) in the workplace as well as psychological job stress (increase in workload, conflicts with supervisors) than did nonaffected workers. Moreover, affected workers scored significantly higher than nonaffected workers on personality tests measuring extraversion and hysteria traits.
对中西部一家电子装配厂中一起疑似群体性心因性疾病事件展开了调查。该工厂有500名员工，其中80%为女性。此次疾病爆发涉及90名上早班的女性工人，她们称因工作场所出现的一种奇怪气味而出现了各种非特异性症状，如头痛、头晕和眩晕。尽管环境检测发现了一些空气中污染物的局部浓度，但未发现可解释疾病持续爆发的环境毒素。对受影响和未受影响的工人进行了临时抽样调查，以评估心理、社会学和工作环境因素对此次爆发的影响。数据分析显示，与未受影响的工人相比，受影响的工人报告在工作场所存在更多身体不适（温度变化、照明不佳）以及心理工作压力（工作量增加、与主管发生冲突）。此外，在测量外向性和癔症特质的人格测试中，受影响的工人得分显著高于未受影响的工人。
