The UK COSMOS team have just completed a pilot study of 3000 participants who were invited to undertake the first COSMOS follow-up.
The pilot study allowed the UK team to establish and optimise processes for participant invitation, and data collection, operating a help-desk, as well as overall project co-ordination.

The team will now analyse the results of the study to determine the optimal method of invitation (via postal mail, email or both) that achieves the best response rate.
Later in 2017, the remainder of the 100,000 UK cohort will be invited to complete the follow-up questionnaire, adopting the lessons learnt from the pilot study.
