Abstract

The motivation for selecting three persons from a dwelling unit (DU)derives from an interest in studying the behavioral relationships amongcertain triads, (e.g., two parents and a child, a parent and twochildren, etc). Computer-assisted DU screening provides the mechanismfor targeted sampling of individuals, pairs, and even triads within aDU. Chromy and Penne (2002) showed how a modification of Brewer's(1963, 1974) method for samples of size two was used to select samplesof 0, 1, or 2 persons from eligible Dus. They also developed a secondadaptation to control the number of pairs selected. Chromy and Penne'smodification of Brewer's method and their adaptation to control thenumber of persons selected from a DU is extended to the case ofsampling triads within DUs. Some empirical data on household rostercomposition, and response rates based on the number of personsselected, are presented from the National Survey on Drug Use and Health(NSDUH). Finally, the results of some simulation of the sampleselection and response process are presented as a means of evaluatingalternatives.
