TwinsUK - The UK Adult Twin Registry: COVID-19 personal experience questionnaire wave 1

All participants with a valid email address or a postal address were sent a questionnaire if they were current members of the TwinsUK registry , if they lived in the UK, and had previously taken part in at least one prior questionnaire (indicating them as engaged participants). The topics covered aim at understanding how social isolation measures might influence both physical and mental health, and what factors help to lessen any negative impact or potentially make a person more at risk.
