The Complex Emotions Hub is a five year UKRI-funded research programme, aiming to advance understanding and care for people living with and experiencing complex emotions often associated with 'Borderline Personality Disorder' (BPD), 'Emotionally Unstable Personality Disorder' (EUPD), and 'Complex Post-Traumatic Stress Disorder' (cPTSD). 

The Complex Emotions hub is one of six hubs of the UKRI Mental Health Platform, a network of researchers with the shared aim of accelerating research into severe mental illnesses (SMI) and improving the diagnosis and treatment of those affected.

Our Aims

What will this research involve?


The Complex Emotions Hub is led by Sheffield Health and Social Care NHS Trust, with primary research sites in Sheffield and Plymouth. The project, funded for five years from April 2024, is developed in collaboration with a range of partners and universities including  the McPin Foundation.

Over the next five years, the Complex Emotions Hub are developing several research projects aimed at deepening our understanding of the challenges faced by individuals with complex emotions, and the care they receive. This knowledge is being used to design and test new treatments and ways of helping that address these difficulties  holistically and compassionately. Part of this research may also explore the potential of using wearables (such as smart watches) and AI algorithms to better support treatment.

The Hub brings together a diverse team of experts from various fields, including researchers with lived experience, to ensure that our work is grounded in real-world perspectives.

Our focus is on improving the understanding and care of individuals dealing with emotional challenges often associated with 'Borderline Personality Disorder' (BPD), 'Emotionally Unstable Personality Disorder' (EUPD), and 'Complex Post-Traumatic Stress Disorder' (cPTSD). Complex emotions can include difficulties in relationships, fears of abandonment, challenges with emotional regulation (including both intense emotions and detachment), and managing harmful impulses such as self-harm or suicidal feelings.

*Many people find these diagnoses to be stigmatising and harmful to their well-being, which is why we are committed to improving both understanding and care approaches for these experiences.

1. Bringing together existing research 


This stage maps the existing literature, related research and theories about complex emotions and 'BPD' to test later. 




2. In-depth understanding of experience 

In this stage interviews are conducted to explore people’s experiences of their complex emotions to understand how emotions vary and what triggers them.

People will also be invited to recording their feelings and emotions and experience in smart tech (such as smart watches or phones apps) to enable us to see how real world triggers and events impact people. 

3. Understanding patterns using electronic health records


Building on existing research, this stage examines how emotional, behavioural, and relationship instability appears in large databases of health records. By analysing how these patterns change over time or in connection with other health conditions, we aim to improve the recognition of BPD in healthcare settings. 

4. Understanding how settings and cultures influence care 

This stage explores people’s experiences of care for complex emotions.  Data collected using semi structured interviews with people with lived experience as well as clinicians, focuses on the relationships between clinicians and service users and how these impact people’s recovery.  


5. Developing new treatment/ approaches 

We will use what we have learned to co-develop and test new ways of helping people who experience complex emotions associated with 'BPD' and other diagnoses, both within the NHS and other settings such as lived experience led projects in the voluntary sector. 


6. What will we do with our findings? 

We will use our findings to produce training and to guide support for health professionals to help them provide improved care for people with complex emotions associated with 'BPD'. This will be done in partnership with people who are experts by experience.
