Plain English Summary

Background and study aims
Polycystic Ovary Syndrome (PCOS) is the most common endocrine disorder amongst women of reproductive age, affecting about 6.5% of women. PCOS is also the most prevalent cause of infertility. Women with PCOS are at an increased risk of miscarriage, cardiovascular disease, type 2 diabetes mellitus and cancer. Symptoms can include hirsutism (excessive hair growth), insulin resistance, infertility and obesity. Studies have shown that PCOS sufferers have higher levels of psychological distress than healthy individuals, including anxiety and depression. Studies show that PCOS can lead to lower quality of life and that women with PCOS are at an increased risk of suffering from a psychiatric disorder, including depression. Positive psychology interventions have been shown to help improve depressive symptoms in participants. Research has found that the positive psychology activity ‘Three Good Things’ (whereby participants were asked to write down three things that went well each day and their causes) increased happiness and decreased depressive symptoms for six months. This study aims to assess the effectiveness of an online positive psychology intervention on improving the quality of life of women with PCOS.

Who can participate?
Patients aged 18 or over who have been diagnosed with PCOS by a clinician, live in the UK and have access to the internet.

What does the study involve?
Participants are randomly allocated to the intervention or the control group. The participants in the intervention group are invited to take part in a 4 week online positive psychology intervention. The positive psychology exercise is "Three Good Things". For this exercise participants are asked to write down three good things which have happened to them on each day of the intervention. They are directed to a website which enables them to fill in their three good things each day. Participants in the control group are asked to go about their usual routine and are offered the intervention after the follow-up period (6 weeks).

What are the possible benefits and risks of participating?
The positive psychology intervention, "Three Good Things", has been shown to increase happiness and decrease depressive symptoms. There are no known risks to participating in this study.

Where is the study run from?
The lead study centre is the University of Derby. The trial is being run in association with a PCOS clinic at the Royal Derby Hospital (UK)

When is the study starting and how long is it expected to run for?

Study information

Scientific title

A randomised controlled trial to investigate whether an online psychology intervention can improve the quality of life of women with polycystic ovary syndrome (PCOS)


Study hypothesis

Women with Polycystic Ovary Syndrome (PCOS) can experience a low quality of life: a non-invasive clinical trial offering an online positive psychology intervention to women with PCOS may, therefore, be beneficial. We propose to carry out a fully randomised clinical trial into the benefits of an online positive psychology intervention for Derby-based women with PCOS over a four week period, using quality of life as an endpoint. This will be the first study to investigate whether an online intervention can improve the quality of life of women with PCOS.
