The ELSA COVID-19 assessment protocol combines new COVID-19 questions with measures used in previous ELSA waves of data collection as detailed below.
We have also been collaborating with the Wellcome Trust initiative coordinating questionnaire content across longitudinal studies, and with international colleagues who run longitudinal ageing studies similar to ELSA.
Questions concerning the experience of symptoms, illness, testing, and hospitalisation of the participant, their household, and people close to them.
Other health issues
New health conditions, access to hospital and primary care, and medication.
Assessed using the CESD depression scale, the GAD7 anxiety scale, and wellbeing measures.
Questions on type of housing, number of rooms, access to private outdoor space, and the number, ages, and relationships of people in the household.
Measured through changes in financial situation, worry about future financial security and ability to buy food, changes in income, receipt of benefits and financial assistance programmes, and expectations for the future.
Changes in work patterns, risk of infection during work, and job security.
Social connections and isolation
Assessed with adaptations of existing measures of frequency of contact with immediate family, other relatives and friends on the telephone, email, and video-conferencing, and quality of relationship with a partner. We will also measure loneliness, internet use, watching TV, volunteering, and caregiving.
Measured through changes in smoking, drinking alcohol, physical activity, eating behaviour, sedentary behaviour, and sleep.
