PY - 2014 DA - 2014/06/25 TI - Adaptive list sequential sampling method for population-based observational studies JO - BMC Medical Research Methodology SP - 81 VL - 14 IS - 1 AB - In population-based observational studies, non-participation and delayed response to the invitation to participate are complications that often arise during the recruitment of a sample. When both are not properly dealt with, the composition of the sample can be different from the desired composition. Inviting too many individuals or too few individuals from a particular subgroup could lead to unnecessary costs or decreased precision. Another problem is that there is frequently no or only partial information available about the willingness to participate. In this situation, we cannot adjust the recruitment procedure for non-participation before the recruitment period starts.
