Wave 1 consisted of just a main interviewELSA 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 birthsPartners - 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 healthHealth - 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 protectionELSA 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 5Risk moduleExp. 1,0002010/11
