Non-responders to a Lifestyle Survey: A study using telephone interviews

Abstract
The study examines 38 per cent (627/1,642) non-responders to a postal lifestyle survey among adults aged 16 to 70 years of age. Non-responders were more likely to be male and aged 16 to 34 years than responders. Thirty-seven per cent (232/627) of all non-responders had an available telephone number. Those with an accessible telephone number were less likely to be aged 34 years or under. Fifty-nine per cent (136/232) of the sample were interviewed by telephone. Compared to original study responders, participating non-responders were more likely to be: males (53 per cent against 44 per cent); aged between 16–34 years (25 per cent against 15 per cent); smokers (37 per cent against 21 per cent) and regular drinkers (57 per cent against 46 per cent) although not necessarily heavier drinkers. Participating non-responders differed in health check attendance being less likely, if ever, to have had a recent eye, hearing, well wo/man or cervical smear check. On the other hand, they were more likely to have been for a dental check in the last year (69 per cent against 58 per cent) and to express a greater need for information about where to go for health care (52 per cent against 24 per cent). They were less stressed by relationships (24 per cent against 36 per cent) but more stressed by caring for their family (60 per cent against 45 per cent). The study sample was not representative of all non- responders. Nevertheless, findings generally confirm results from previous studies and identify non- responders, including those who respond to this type of follow-up, as having specific demographic and health- related characteristics which are different from those of responders. The health needs of non-responders, which are often not considered, need to be addressed.
