Historia biográfica

The Twins' Early Development Study (TEDS) was established in 1994 with the support of the Medical Research Council (MRC) and is based at the Social, Genetic and Developmental Psychiatry Research Centre of the Institute of Psychiatry, King's College London. It was set up to investigate the development of three common psychological problems in children: communication disorders, mild mental impairment and behaviour problems, using sets of twins to test the relative importance of environmental and genetic causation in determining their onset, with autism as a main line of enquiry. Studies also include the process of skill development such as language skills and story telling. The project comprises initial and yearly follow-up face to face and telephone interviews and written responses taken from around 16,000 pairs of twins born in England and Wales between 1994 and 1996 and their parents and teachers, and more lengthy and detailed responses from the parents of those children who developed problems.

The twins were identified and located by the Office for National Statistics, which manages the principal name list. This data has been combined with genetic sampling to gauge the contribution of inheritance to language and cognitive development. The study is one of the largest of its kind in the world and also comprises a number of working groups using samples of raw data from smaller cohorts to analyse specific aspects of the behavioural development of young children. Notably, groups are investigating the influence of other siblings in the twins' home lives and on `Environmental Risk' factors in child development.

Regular accruals

The collection consists of questionnaires arranged into four sections of interviews and responses of 1, 2, 3 and 4 year-olds with additional sections on sibling and environmental sub-studies. Each twin and parent is assigned a unique identifier number that is retained throughout the course of the project. The identifier comprises a four or five digit number for each family/parent and a three number suffix unique to the individual child. Within each annual series, the questionnaires are divided into sets of three for the mother and each of the twins, colour coded between years for quick reference, and into a number of tranches comprising several hundred names arranged in broadly numerical order. These batches were created when raw questionnaires were sent for data inputting and the arrangement has been retained for ease of recovery of particular files. The Archives possess a master list of families and twins with identifier numbers and box locations. Some twins' files have been retained by the SGDP and this is noted on spreadsheet indexes.

The collection contains sensitive personal information and medical details and is closed under statutory rules governing data protection.

Collection closed to the general public.

A catalogue of the contents of the collection is available online and in hard copy in the King's College Archives Reading Room on the King's Strand Campus. A series of spreadsheets indexing the contents of the collection by box number, family name and identifier code, is retained by Archives.
