Twins Early Development Study (TEDS)
About the cohort
Start date: 1994-96
Age at recruitment: 0
Sample size at recruitment: 13,690 (families)
Estimated current sample size: 21,800
The Twins Early Development Study is one of the foremost on-going twin studies of its kind in the world. With the help of over 15,000 families, TEDS researchers and academics are exploring how we develop through childhood and adolescence and what factors contribute to making each of us who we are. In this way, the great wealth of information gathered through the study is providing insights into how both nature (the genetic material and characteristics we inherit from our parents) and nurture (our environment) contribute to individual development in a range of areas, such as cognitive and learning abilities, and behaviour. The study has been going since 1994 and is based at King's College London under the leadership of Professor Robert Plomin.
Since recruitment the cohort has been contacted 11 times at age 2 years, 3 years, 4 years, 7 years, 8 years, 9 years, 10 years, 12 years, 14 years, 16 years and 18 years.
