Study documentation
Main interview documentation
Main questionnaire (CAPI)
Main self-completion questionnaire (PAPI)
*Part-way through Wave 7 fieldwork, it was noticed that the answer scale of some questions on the self-completion questionnaire was set out as six point 1-6 scale, as opposed to the intended seven point 0-6 scale. A new version of the self-completion was issued part-way through fieldwork with the corrected scale.
Therefore, two versions of each of the affected variables are provided in the dataset, with the variable name suffix indicating the self-completion version completed ( _v1: Orange questionnaire, scale 1-6; _v2: Green questionnaire, scale 0-6).
Additionally, the variable SCVER in the Wave 7 dataset provides information on which version of the self-completion questionnaire was completed by each respondent.

All ELSA interviews are conducted face-to-face using computer-assisted interviewing (CAPI), combined with self-completion questionnaires completed using pen and paper (PAPI).
A CAPI interview and PAPI self-completion questionnaire administered by an interviewer are carried out at every wave.
A CAPI interview and collection of bio-measures by a qualified nurse have been carried out for all participants at waves 2, 4 and 6 and for half of the participants in waves 8 and 9.
Full details can be found in the Waves 1-9 data user guide.
