81 women were tested in early pregnancy with a personality questionnaire (FPI), a bodily symptoms checklist and a structured questionnaire with respect to various psychosocial events. Women with and without Emesis in early pregnancy differ significantly according to the following characteristics: Quality and quantity of past and present bodily symptoms, psychosomatic affect-resonance, calmness, occupational attitudes, description of family-relationship and expectancy to vomit. Results are interpreted that vomiting in early pregnancy seems to be a psychosomatic reaction, based on a extenuated perception of reality, in combination with difficulties "leaving home" as well an expectancy to vomit in pregnancy.
81名女性在怀孕早期接受了一项人格问卷（FPI）、一份身体症状清单以及一份关于各种心理社会事件的结构化问卷测试。怀孕早期有呕吐和无呕吐的女性在以下特征方面存在显著差异：过去和现在身体症状的质量和数量、身心情感共鸣、平静程度、职业态度、家庭关系描述以及呕吐预期。结果表明，怀孕早期的呕吐似乎是一种身心反应，基于对现实的减弱感知，同时伴有“离开家”的困难以及对孕期呕吐的预期。
