4 History of ELSA Wave 1 2002/3 Wave 2 Nurse visit 2004/5 2006/7 Wave 3
Original sample interviewed in HSE 1998/1999/2001 Age 50+ on 1 Mar 2002 Wave 1 12,100 2002/3 Wave 2 9,432 Nurse visit 7,666 2004/5 New cohort sample HSE 2001/02/03/04 Age on 1 Mar 2006 2006/7 Wave 3 9,771 Life-history 7,855 Refreshment sample from HSE 2006 Age on 1 Mar 2008 2008/9 Wave 4 11,050 Nurse visit 8,641 This diagram shows the history of the ELSA study. ELSA Wave 1 began in 2002, the original sample was taken from the Health Survey for England (HSE) – we call the HSE Wave 0. Wave 1 consisted of just a main interview ELSA Wave 2 took place in 2004, at this wave there was a core interview and a nurse visit. ELSA Wave 3 was carried out in 2006 and consisted of a core interview. The sample was refreshed by the HSE sample at this wave. Later on that year we also carried out a life history interview with some ELSA respondents. Life history interview asked about the respondents’ lives prior to joining ELSA – from early childhood to the date they joined ELSA. Information collected using a life grid – to aid recall. Includes questions on: Children - natural, adopt, foster, miscarriages, abortions, still births Partners - cohabiting and non-cohab (social networks) Accommodation - addresses for 6 months or more, Work - jobs for 6 months or more, changes in employer, pt or ft, salaries, activities between jobs, whether left because of ill health Health - injuries, - childhood health (missed school, hospitalisation, list of conditions and when, impact on current life) - adult health (conditions lasting for more than 1 yr, age, long term effects) - smoking history - gynaecology (age periods started, hysterectomy, ovaries, removed, menopause, HRT) Parents - separation from mother, divorce, care and protection ELSA Wave 4 took place in 2008, there was a core interview and a nurse visit. The mainstage sample was refreshed by the HSE 2006 sample at this wave. Wave 5 began in June 2010. Additional risk module which is a module of questions (or rather games) on attitudes towards financial risk. Games measure willingness to accept a delay in receiving money – deferred gratification and how risky or risk averse they are. Collected in combination with the financial data analyse people choice of pensions, assets etc. Only a sub-sample of just over 1,000 ELSA respondents aged 50 to 74 will be asked this module of questions. Wave 5 Risk module Exp. 1,000 2010/11

5 Main Interview Content
Household and individual demographics Health Social participation Work and pensions Income and assets Housing and consumption Cognitive function (assessments) Expectations Effort and reward (of voluntary work and caring) Psychosocial health Timed walk (for those 60+) Self-completion These are the sections of the main ELSA interview. Interview is roughly 80 mins for 1 resp 120 mins for two. Social participation – questions on transport – private and personal, a couple of questions on how they feel about their local area. Cognitive function – respondents carry out a number of activities to measure their short and long term memory, prospective memory (remembering to remember), verbal fluency, mental speed and visual scanning, numeracy and literacy. Expectations – expectations for the future – what degree of certainty they have about future events occurring e.g. living to a certain age, their future health, receiving an inheritance Psycho social health – views on life e.g. how often during the last week they were happy, depressed, lonely Timed walk – ask those aged 60 and above to walk 8ft (244cm) twice. Self-completion – includes questions on quality of life, social participation, life satisfaction, well-being, personality, social networks, religion, discrimination, diet and alcohol consumption. We also ask consent to link to NHS Central Register, Health and economic records.
