Good systems For maintaining contact and locating Study members, good systems are essential. At each assessment we ask the Study members for contact details of people who know them well and are likely to know their movements over time. We have requested this type of information at multiple phases and have consequently built up a substantive ‘contacts’ database for each Study member. This information is augmented by change-of-address forms returned to us following the mail-out of regular newsletters to Study members. The directors of the study have paid special attention to this task during assessments, helping maintain and strengthen the bond between the study and the Study members over time.
