Evaluating Race-of-Interviewer Effects In a National Survey

Abstract

The present article attempts to overcome some of the problems involved in estimating race-of-interviewer effects in a nonexperimental national survey. Individual items as well as scales were examined, using General Social Survey (GSS) data. Race-of-interviewer effects large enough to justify the practice of matching interviewer and respondent race for interviews on racial topics were found for both black and white respondents. A few such effects were found for nonracial items among blacks, but the range of items involved is smaller than what has been reported in previous studies. The impact of race-of-interviewer effects on mean estimates in the GSS appears to be small for white respondents, due to the small proportion of cross-race interviews. The proportion of cross-race interviews among blacks is larger and more variable over the years, and the impact of race-of-interviewer effects should be considered when analyzing items which show these effects.
