Menstrual cycle characteristics and psychology
We are interested in how people’s personality, emotions and behaviour may change across the days of their menstrual cycle. Previous research has not yet provided a clear answer to this question, so our study seeks to gain a clearer and more detailed understanding of these changes. We intend this research to form the foundations of a larger scientific and social movement that supports women’s understanding of their own menstrual cycle, and by extension improves their health and wellbeing.
Research Questions / Hypotheses
This study is exploratory, meaning we have not formed any specific expectations about the patterns that might emerge from participants’ responses. We are particularly interested in how the menstrual cycle impacts health (e.g., sleep, exercise), social behaviours (e.g., competition, cooperation) and mood.
119 REP Participants in total. Exclusion criteria included people without a regular menstrual cycle, anyone with a fertility abnormality, POCS or endometriosis. People who are trying for pregnancy, are breastfeeding or who are currently experiencing menopause were also excluded.
Each day participants were asked to complete a 5 minute survey. Each survey contained a select number of questions, drawn from a larger pool of psychological measures. We also asked questions about the menstrual cycle and birth control.
The results of this study will be analysed in a number of ways. For example, we are interested in identifying differences between naturally cycling women and women that use contraceptives. However, we are also interested in whether or not there are clear differences in behaviour/psychology at different times in the cycle (e.g., during the menstrual phase compared to when ovulating).
The results of this research are planned for a number of journal articles. Each article is designed to educate the scientific community about how the menstrual cycle influences individual psychology.
