Dear Georgios,

In the harmonised datasets, variables with different names in BHPS were renamed to the UKHLS equivalent, so yes, doid/doim/doiy4 were renamed to istrtdatd/istrtdatm/istrtdaty.

intdatd_dv/intdatm_dv/intdaty_dv are not the same as they include imputed data, and are available for all household members rather than just adult interviews. The description in the online documentation explains this, e.g. https://www.understandingsociety.ac.uk/documentation/mainstage/dataset-documentation/variable/intdatd_dv

The end date variables are only available from Wave 5 onwards. As we are now fielding many questionnaires via web it may be more likely that people would not complete their interview in one sitting, and there is also the ability for an interviewer to visit the home of someone who started their interview online to try to complete it with them, and in that case it would be on a different day. The end hour and minute variables are available for all waves of BHPS and UKHLS, and in BHPS these would be recorded manually. The end seconds variable is available from UKHLS Wave 1 when CAPI interviewing began. I will check with the fieldwork team whether it can be assumed that all interviews before Wave 5 were completed on the same day they began.

Best wishes,
Stephanie

Dear Georgios,

The fieldwork team say it is reasonable to assume that interviews before Wave 5 were completed on the same day they began.

Best wishes,
Stephanie
