Data collection

The postal questionnaire was sent out when study members were aged 68; up to two reminder letters were sent to those who did not return a completed questionnaire.

The home visit was conducted over the next 18 months by research nurses recruited and employed by the fieldwork partners Kantar Public and Medicals Direct Group. An electronic questionnaire was administered by nurses using laptop computers to ask about health, disability, medication, smoking and exercise habits. Nurses took measurements of body size, blood pressure, grip strength and respiration and administered tests of balance and walking speed. They also took a blood sample which were spun within the study members home.

During the course of the home visit the study member was asked to complete a short paper questionnaire, the short (28 item) General Health Questionnaire. Nurses also administered the Addenbrooke’s Cognitive examination (ACE-III), visual search task and finger tapping test. At the end of the home visit study members were asked if they would like to wear an activity monitor for the following seven days. Nurses left a short activity questionnaire with the study members who had consented to wear the monitor and this was to be completed and returned by post along with the monitor at the end of the seven day period.

Training for data collection

The study team and specialist colleagues trained the nurses over consecutive two days. The nurses’ instruction manual is available to view.
