| Annotation | Response rates for surveys are known to decline with age. Survey results can be affected by response bias if non-responders are more, or less, likely than participants to suffer from the conditions being studied. For instance, it is possible that older people with dementia would be less likely to participate in a study of dementing disorders. A random sample of a rural US population aged over 65 yielded more than 1,422 participants and 912 refusers, in addition to others who were ineligible, inaccessible, or untestable. Participants and refusers were compared on age, sex, 5-year mortality, and causes of death suggestive of dementia as listed on death certificates. Compared to participants, refusers were significantly older and more likely to be women, with mortality similar to that of participants at 5-year follow-up. Death certificate data revealed no significant differences in reported causes of death indicating or suggesting dementia. In the sample population, those who refused to participate in a dementia survey were not more likely to be ill or demented than those who did participate. (RH). |
