Selective nonresponse bias in population-based survey estimates of drug use behaviors in the United States.

ABSTRACT:

Purpose

There is a trend of decreasing response rates in population surveys, and selective nonresponse represents a major source of potential bias in population-based survey estimates of drug use behaviors, especially estimates based on longitudinal designs.
