Sampling Methods for Random Digit Dialing
TLDR
A method of sample selection for household telephone interviewing via random digit dialing is developed which significantly reduces the cost of such surveys as compared to dialing numbers completely at random.Abstract:
A method of sample selection for household telephone interviewing via random digit dialing is developed which significantly reduces the cost of such surveys as compared to dialing numbers completely at random. The sampling is carried out through a two-stage design and has the unusual feature that although all units have the same probability of selection, it is not necessary to know the probabilities of selection of the first-stage or the second-stage units. Simple random sampling of possible telephone numbers, within existing telephone exchanges, is inefficient because only about 20 percent of these numbers are actually telephone numbers assigned to households. The method of selection proposed reduces the proportion of unused numbers sharply.read more

Recent Patterns of Medication Use in the Ambulatory Adult Population of the United States: The Slone Survey
TL;DR: In any given week, most US adults take at least 1 medication, and many take multiple agents; the substantial overlap between use of prescription medications and herbals/supplements raises concern about unintended interactions.

Interviews by Telephone and in Person Quality of Responses and Field Performance
TL;DR: In this paper, a small carefully controlled field experiment was conducted to test the effects of alternative interviewing strategies on the quality of responses and on field performance, including ability to answer complex knowledge and attitudinal items, response validity, and willingness and consistency in providing personal information.

The Uses of Telephone Directories for Survey Sampling
TL;DR: Surprisingly, some of the methods for combining directory sampling with random digit dialing and some door-to-door listing to obtain various levels of sample quality are not only higher in quality, but less expensive than methods that use random dialing or door- to- door listing exclusively.
