Many children who have taken part in the CALM project over the years have experienced some difficulties in school at some point. We are interested in knowing how children who took part in the CALM study are doing during lockdown. For many children it is likely that there will be little impact, but for others the lockdown period could have positive, mixed or more negative consequences. We have put together a brief questionnaire about children’s current experiences. We are inviting families who have visited CALM to complete this questionnaire. If you have visited CALM and would like to help with this study, please email: CALM@mrc-cbu.cam.ac.uk for more information.
