Improving the efficiency of data quality back checks: A new procedure to prevent curbstoning

The purpose of this chapter17 is to describe our efforts in introducing a procedure that improves the efficiency of detecting fake interviews in the Survey of Health, Ageing and Retirement in Europe (SHARE; Börsch-Supan, et al., 2013) during fieldwork. There had been two key innovations in Wave 7: first, the development of a technical script to identify interview fabrication; second, the solicitation of feedback on back checks in a more formalised and systematic way.
