Project title: How does PMDD affect relationships?
Researcher(s):
Avryl Yu (bo.l.yu@durham.ac.uk); Eunice Cheng (yating.cheng@durham.ac.uk); Hannah Poon (heng.n.poon@durham.ac.uk); Mary McNeill (mary.mcneill@durham.ac.uk); Supervisor: Sophie Hodgetts (sophie.hodgetts@durham.ac.uk)
You are invited to take part in a research study we are conducting as part of our undergraduate dissertation. This study has received ethical approval from the Psychology Ethics Sub committee of Durham University. Before you decide whether to agree to take part it is important for you to understand the purpose of the research and what is involved as a participant. Please read the following information carefully and get in contact if there is anything that is not clear or if you would like more information. The rights and responsibilities of anyone taking part in Durham University research are set out in our ‘Participants Charter’: https://www.dur.ac.uk/research.innovation/governance/ethics/considerations/people/charter/
What is the purpose of the study?
This study builds upon the findings of Hodgetts and Kinghorn (2025), which demonstrated that love and commitment remained specifically resilient in relationships affected by Premenstrual Dysphoric Disorder (PMDD). We aim to investigate mechanisms underlying this phenomenon. Our primary goal is to move beyond previous research and understand exactly how and why PMDD impairs relationship trust and satisfaction, but fundamental connection remains intact. We also want to find out what interventions and self-developed coping mechanisms are effective in mediating symptoms of PMDD.
Why have I been invited to take part?
You have been invited because you are in a relationship with someone who has regular menstrual cycle (either with and without PMDD), and you are over the age of 18.
Do I have to take part?
Your participation is voluntary, and you do not have to agree to take part. If you do agree to take part, you can withdraw at any time, without giving a reason and without any negative consequences such as prejudice or penalty.
What will happen to me if I take part?
For this study, you will be asked to:
• Fill out a questionnaire about PMDD that takes no more than 15 minutes to complete.
• This questionnaire will ask you to:
Complete a PMDD screening procedure Rate aspects of your relationship quality on a 1-7 scale Rate the likelihood of different problems arising in your relationships on a 1-9 scale
Are there any potential risks involved?
We may discuss some sensitive issues concerning your experiences living with PMDD. For example, we may ask you to think back on any difficult, upsetting or negative experiences within your relationship due to PMDD.
Will there be any physical discomfort?
There should not be any physical discomfort. Will there be any psychological discomfort or embarrassment? There may be some psychological discomfort if the experiences we are asking you to talk about are upsetting/difficult for you to reminisce and discuss.
Can I withdraw from the experiment?
You are free to end the questionnaire at any time, without having to give a reason for withdrawing, and without any negative consequences, such as prejudice or penalty. You can do this by closing the browser and any current answers filled out will be removed and not included in the project. However, if you complete and submit the questionnaire, your data cannot then be withdrawn as responses are anonymised after submission.
Will I receive any compensation for taking part?
No.
Will my data be kept confidential?
All information obtained during the study will be kept confidential and if the data is published it will not be identifiable as yours. You will be allocated an anonymous number accessible only by the research team. Your identity will remain anonymous and confidential, will not be disclosed or shared in any circumstances, and will not appear in any publication.
What will happen to the results of the project?
No personal data will be shared, however anonymised (i.e., not identifiable) data may be used in publications, reports, presentations, web pages and other research outputs. At the end of the project, anonymised data may be archived and shared with others for legitimate research purposes. All research data and records needed to validate the research findings will be stored for 10 years after the end of active data collection.
