Abstract The potential for improving response rates by changing from one mode of data collection to another mode is examined in this paper, along with the consequences for measurement and nonresponse errors. Using an initial sample of 8,999 households, di-vided into four treatment groups, data collection consisted of two phases. Phase 1 data collection was conducted by telephone interview, mail, interactive voice response, and the Internet, Phase 2 consisted of nonrespondents to Phase 1, and was conducted by telephone for the groups initially surveyed by mail, IVR or the Internet, and by mail for the initial telephone group. In gen-eral, results from our study suggest that switching to a second mode is an effective means of improving response. We also find that for the satisfaction-dissatisfaction questions asked in these surveys, respondents to the aural modes (telephone and IVR) are significantly more likely than are respondents to the visual modes (mail and web) to give extreme responses on the positive ends of the scales. This difference cannot be accounted for by a tendency towards recency effects on the telephone. In general, switching to a second mode of data collection was not an effective means of reducing nonresponse error on demographic vari-ables.
