The Emotional Development, Interventions and Treatment (EDIT) lab is led by Prof Thalia Eley and consists of post doctoral researchers, PhD students, and both undergraduate and masters students. We are based at the SGDP Centre at the Institute of Psychiatry, Psychology & Neuroscience, King’s College London. We study genetic and environmental influences on the development and treatment of anxiety and depression. The EDIT lab team members write a blog which covers a range of topics related to our research. Our current series is called ‘mythbusters’ and addresses many common questions and concerns raised by our participants.
Several studies are led from this group. Prof Eley’s most long-standing study is Genesis1219, a twin study of adolescent emotional development. Prof Eley has also recently become Director of the Twins Early Development Study (TEDS) and she and Dr Tom McAdams run the Children of TEDS study (CoTEDS) . We also work very closely with the Translational and Neuropsychiatric Genetics (TNG) group, which is run by Prof Gerome Breen. Profs Eley and Breen jointly lead both the Fear Learning and Anxiety Response study (FLARe) and the Genetic Links to Anxiety and Depression Study (GLAD), which is the world's largest study on depression and anxiety, designed to investigate the influence of our genes on depression and anxiety.
The EDIT Lab strives to be a diverse and supportive research environment that is open and welcoming to all. We recognise that certain groups have a more difficult journey into academia, so we would especially like to hear from you. We have a particular focus on open and collaborative approaches to science. You can read more about this in the "Group Culture" tab below.
Projects

GLAD: Genetic Links to Anxiety and Depression
The GLAD Study is the largest anxiety and depression project ever undertaken. The study is part of the National Institute of Health Research (NIHR) BioResource.

TEDS: Twins Early Development Study
The Twins Early Development Study (TEDS) is one of the leading twin studies in the world. The study began in 1994 led by Professor Robert Plomin, and has followed over 15,000 pairs of British twins throughout their childhood, adolescence and into early adulthood. Professor Thalia Eley is the incoming director of TEDS. The study's main goal is to investigate how genetic and environmental factors contribute to children’s development, including their behaviour and cognitive abilities, and what kind of influence they have in later life. Over 13 waves of data collection, the twins and their families have provided us with invaluable information about their experiences and other individual factors that might have influenced them during their lives. Additionally, we have collected DNA samples from more than 5,000 pairs of twins and are using this data to improve our understanding of the effect of genes on abilities and behaviours. We actively encourage and facilitate the sharing of our data. On the TEDS project website there is a page specifically for researchers. This includes access to the TEDS data dictionary which provides documentation on all the data that has been collected. There is also a TEDS publication search engine and a current TEDS project search engine. On these pages, researchers can learn about the steps involved in accessing and using our data.

CoTEDS: Children of Twins Study
The Children of TEDS study, or CoTEDS, was launched in 2017. We are collecting data from the children of the now grown-up TEDS twins, making this the first ever twin study to include information on both twin parents and their offspring. This will help us establish how different behaviours and traits are passed down through generations. As the adult parents are twins, we are able to disentangle whether traits run in families because of genetic inheritance, because of living together, or both. This is because when identical twins have children, those children are as just as genetically similar to their parents as they are to the twin of their parent. However, it is only their own parent that will provide the child with their rearing environment, since the adult twin pairs will raise their respective children in different environments. Identifying the ways in which emotional problems are transmitted from one generation to the next provides clues for the best places to focus on in regards to intervention and early treatment. If you are a TEDS twin and are interested in becoming a part of this research, please register with the link below for further information. It doesn't matter how much or how little you were were involved in past TEDS research, this is a new and equally exciting opportunity!

FLARe: Fear Learning and Anxiety Response
FLARe aims to model the processes underlying the development, maintenance and treatment of anxiety disorders, and post-treatment relapse. Some people learn very quickly that certain things make them feel anxious, whereas others are less likely to experience these feelings. Similarly, there is variation in how quickly anxiety reduces following a stressful experience, and in how successfully people who are anxious respond to exposure based treatments. In this study, we are interested in how people learn to be anxious of new things, and how they learn that some things that make them feel anxious might not always be unpleasant. We are also interested in the ways in which genes and the environment might contribute to this.

G1219: Genesis 1219
G1219 is a longitudinal study that aims to examine the interplay between genes and the environment on the development of anxiety and depression over time. We have also regularly assessed other aspects of development including aggression and sleep quality, and environmental experiences including life events and peer group difficulties.

Group Culture and Alumni
The EDIT Lab strives to be a diverse research environment that is open and welcoming to all. We are committed to encouraging, promoting and maintaining diversity of all kinds in both our research group and in our studies. We believe that research can only be relevant to all if we have voices that represent everyone and are trying to produce a truly representative research base.
We are also engaging actively with the open science movement. We strongly believe in the importance of undertaking and reporting our science to the highest possible standards, with a particular focus on collaborative approaches and replication.
Our specific efforts in these domains are listed below.
Diversity
- The EDIT Lab stands with the Black Lives Matter movement.
- The EDIT Lab supports the LGBTQI+ community.
- We welcome and support team members regardless of their age, gender identity, race, sexual orientation, disability or religion.
- Members of the EDIT lab are active in the KCL SGDP Diversity and Inclusion panel meetings.
- Members of the EDIT lab are actively engaged in encouraging secondary school students to continue studying science subjects and pursue careers in science.
- The EDIT lab members are committed to learning more about issues of diversity, cultural sensitivity and regularly discuss these within lab meetings.
- Members of the group are working with a highly experienced research assistant to consult on issues of diversity and inclusion (as we recognise we are currently not best placed to do this).
- The EDIT lab intends to share best practice on all matters of inclusivity within our department and across wider KCL faculties.
- The EDIT lab wants to support individuals from groups that are under-represented in academia, and are willing to offer mentoring on a case by case basis (please email thalia.eley@kcl.ac.uk if interested).
Open Science
- We discuss open science strategies including preprints, the Open Science Framework, open access publication and publishing of analysis scripts regularly in the group, with more established team members providing support and examples to newer members of the lab.
- Starting 2020, we are pre-registering all new analysis plans on the Open Science Framework.
- We are regular attendees of the Reproducible Interpretable Open Transparent (RIOT) Science Club.
- Lab members have developed strategies to use GitHub collaboratively to improve peer based review and sharing of code.
- We support sharing of code and data (where possible) on publication of our papers.
- We archive our papers at the point of submission whenever possible.
- The EDIT lab views mistakes made by those at all levels as opportunities for shared learning; this is not a blame culture.
