The public's knowledge about and reaction to AIDS; data from 22 surveys, 1983-86; U.S.

Sometimes R's are not available & informants have to be used to gain data about R's. Issues connected with use of informants were studied through a longitudinal study of the soc & econ consequences of therapy with the drug levodopa for patients with Parkinson's disease, carried out in the Sum of 1970 by the Center for Policy Res. "Informant interviews" were specified for every 4th patient in the sample (N=169) who was rated by his MD as being disabled to function as R. Agreement between informant's & R's response & the direction of diff's were explored. There was a high level of agreement on most items, though various factors, eg, when the informant sees the patient as more helpless than he is, may introduce distortion. Limitations of the sample are noted. It is concluded that, when questions are relatively objective, when informants have a high degree of observability with respect to R's, when the pop is fairly homogeneous, & when the setting of the interview provides no clear-cut motivation to distort responses in one direction or another, the information obtained from informants is likely to match that given by R's reasonably well, & diff's between them are likely to be small & random. When these conditions do not obtain & substantial use is made of informants for inaccessible R's, agreement between the 2 should be independently assessed. 1 Table. M. Maxfield.

It is shown that the index to the Public Opinion Quarterly cannot be an objective record of the res that was done because it is dependent upon editorial decisions. It is pointed out that PO res'ers are concerned with issues that are salient to the time the res was undertaken. Examples from the index are presented to substantiate this. It is shown that not only is the res related to specific historical periods, but also the terminology which is used changes. A delineation of the types of perennially interesting res is made. G.

This article is intended to supplement rather than replace earlier reviews of research on survey incentives, especially those by Singer (2002); Singer and Kulka (2002); and Cantor, O'Hare, and O'Connor (2008). It is based on a systematic review of articles appearing since 2002 in major journals, supplemented by searches of the Proceedings of the American Statistical Association's Section on Survey Methodology for unpublished papers. The article begins by drawing on responses to open-ended questions about why people are willing to participate in a hypothetical survey. It then lays out the theoretical justification for using monetary incentives and the conditions under which they are hypothesized to be particularly effective. Finally, it summarizes research on how incentives affect response rates in cross-sectional and longitudinal studies and, to the extent information is available, how they affect response quality, nonresponse error, and cost-effectiveness. A special section on incentives in Web surveys is included. [Reprinted by permission of Sage Publications Inc., copyright The American Academy of Political and Social Science.]
