Our Studies

The Loneliness in the Digital World study was launched on the 10th of April 2024.

This study aims to recruit 200 young people ages 12–15 to join the study. The study explores how various types of social interaction, both positive and negative, in-person and online, impact state loneliness (i.e. a more temporary and situational experience of loneliness, which specific events or circumstances may influence) and mental health in adolescents.

Study Methodology

The study uses an Ecological Momentary Assessment design to assess offline/online social acceptance and rejection in young people and examine how different types of social interaction affect state loneliness, emotions and broader well-being. The study is also co-produced with a group of young people. Our Young People Advisory Group (YPAG) helped the researchers design and shape the research question and design.

The Scottish Family Health Study is an intensively phenotyped, family-based cohort for the study of the genetic basis of common complex diseases and response to treatments. Recruitment began early in 2006 and was completed in 2011. The cohort includes just over 24,000 participants, with most consenting to record linkage and recontact.

Each participant gave blood or saliva samples (for processing, biochemistry and cryopreservation) and a urine sample.  The blood or saliva samples were processed to DNA and extensive genotyping was carried out on over 20,000 participants by 2015.

Genotype

DNA from over 20,000 Scottish Family Health Study participants has been analysed by high density genome-wide chip genotyping, Illumina OmniExpress SNP GWAS (700k) and exome chip (250K), with low failure and high call rates. Quality control analyses were performed, data cleaned using quality scores and proportions typed. Sample identity was verified against recorded gender and pedigree and data checked for unknown relationships based on estimated identity-by-descent. Population stratification was assessed by analysis of principal components and imputing all data to the 1000 Genome data set.

We worked closely with collaborators on generating genetic data on its resource, in particular with the Quantitative Trait Locus (QTL) group at MRC Institute of Genetics and Cancer.

Genetic Health in the 21st Century is a resource of control DNA and genetic and phenotypic information. The study includes nearly 2,000 consenting individuals from 6 different locations across Scotland. It is designed to help establish the genetic profile of a control population living in Scotland in relation to health and disease. Recruitment took place in Aberdeen, Banff, Dundee, Edinburgh, Glasgow and Peterhead.

Study Methodology

DNA was extracted from all blood samples and archive and working stocks prepared. Purified blood cells were stored and can be used to make lymphoblastoid cell lines.

We collected human control DNA samples and plasma from blood donors attending sessions at the Scottish National Blood Transfusion Service, in more than 140 locations throughout Scotland.

Recruitment took place during 2008 and the collection contains almost 5,000 samples with accompanying data.

Study Methodology

Please see the following reference for a description of the methods used:

• Generation Scotland: Donor DNA Databank; A control DNA resource

The purpose of of the Donor DNA Databank is to provide a long term, well characterised resource of human DNA control samples. 'Case' samples are unique to each disease study, but the same control samples can be used across many studies if appropriately collected and characterised. The Donor DNA Databank provides access to a collection of well-maintained stocks of control DNA obtained with consent from the Scottish population. Donors answered a short questionnaire and allowed a sample of their blood and a filter, which would otherwise be discarded, to be used by the project. Questionnaire data was entered into the databank using Optical Mark Read (OMR) technology. The collected data, DNA and plasma samples were unlinked and fully anonymised 28 days after collection.

Over 25,000 people have taken part in either CovidLife, TeenCovidLife or RuralCovidLife. Their support is helping us to begin understanding health and well-being. Data are available for research use.

Our CovidLife surveys launched in April 2020, over different time periods and under different UK regulations. If you'd like to take a look at when each survey was launched and how long it ran for, take a look at our timeline.

CovidLife Survey Timeline 

Image

The CovidLife survey was launched on 17th April 2020 in response to the coronavirus (COVID-19) pandemic. In our baseline survey, we asked ~18,000 people a series of questions about how COVID-19 measures had been affecting them. Our second survey was completed by ~11,000 volunteers and our third survey y ~10,000 volunteers.

We invited people over the age of 18 and living in the UK to take part. Our volunteers included over 13,000 members of the general public and over 4,000 Generation Scotland participants. They were asked questions about the impact of the pandemic on their health, well-being, social and work life and education. The survey was conducted online, using Qualtrics.

The TeenCovidLife survey was launched on 22nd May 2020. In our baseline survey, we asked ~5,500 young people a series of questions about how COVID-19 measures had been affecting them. Our second survey was completed by ~3,000 new and previous volunteers and out third survey by ~700 volunteers.

We invited young people aged 12-17 to get involved. They were asked questions about the impact of the pandemic on their school and home life, as well as their overall health and well-being. The survey was conducted online, using Qualtrics.

The RuralCovidLife survey was launched on 14th October 2020. In our baseline survey, we asked ~3,000 rural Scottish volunteers, aged 16 and over, a series of questions about how COVID-19 measures had been affecting them.  The questions were tailored and designed by people from rural communities. We did this to make sure we asked about topics relevant to our volunteers.
