Nonresponse pattern and bias in a community-based cross-sectional study of cognitive functioning among the elderly.
The demographic, health, and mental functioning characteristics of nonresponders to a community-based cross-sectional study of cognitive functioning among the elderly in Amsterdam, the Netherlands (Amsterdam Study of the Elderly (AMSTEL), October 1990 to May 1991), were examined and compared with responders.
The randomly selected age-stratified (65-74,75-84 years) sample was drawn from nonresponders listed with a subsample (n=8) of general practitioners whose lists served as the sampling frame for the main study.
The general practitioners approached and interviewed the responding nonresponders using the same standardized questions that were used in the main study.
Nonresponders (n=115) and responders (n=999) from the same medical practices were compared by means of chi-square and odds ratios.
