Although women predominantly report negative premenstrual changes, a substantial portion of women also reports positive changes. Little is known about factors related to report of positive and negative premenstrual changes. The aim of this experimental study at the Philipps-University of Marburg from January and February 2015 was to investigate the effect of manipulated information about premenstrual changes on the retrospective report of premenstrual changes. A total of 241 healthy women were randomly assigned either to an experimental group (EG) reading: (1) text focusing on negative and positive premenstrual changes (EG1 (+/-)); (2) text focusing on negative changes (EG2 (-)); or (3) control group (CG) text. At least one positive premenstrual change was reported by the majority of the participating women. The results of the MANOVA and discriminant analysis showed that, after having read the text, EG2 (-) reported more negative and fewer positive premenstrual changes in a retrospective screening compared to EG1 (+/-) and CG. No significant difference was observed between EG1 (+/-) and CG. The results show the negative influence of information focusing on negative premenstrual changes on the retrospective report of both negative and positive premenstrual changes.
尽管女性主要报告经前出现负面变化，但仍有相当一部分女性报告了积极变化。关于与经前正负变化报告相关的因素，我们所知甚少。这项于2015年1月至2月在马尔堡菲利普斯大学进行的实验研究，旨在调查经前变化的操控性信息对经前变化回顾性报告的影响。共有241名健康女性被随机分为实验组（EG），其中实验组阅读：（1）关注经前正负变化的文本（EG1(+/-)）；（2）关注负面变化的文本（EG2(-)）；或（3）对照组（CG）文本。大多数参与研究的女性报告了至少一种经前积极变化。多变量方差分析（MANOVA）和判别分析结果显示，阅读文本后，与EG1(+/-)和CG相比，EG2(-)在回顾性筛查中报告的经前负面变化更多，正面变化更少。EG1(+/-)和CG之间未观察到显著差异。结果表明，关注经前负面变化的信息对经前正负变化的回顾性报告均有负面影响。
