Abstract
Results from studies that compare different methods of data collection may be confounded in many instances because of differences in response rates or sampling frames. Two alternatives to in-person interviewing were designed to overcome these confounding factors. One strategy utilized the telephone with in-person interviewing as a back-up when phone numbers were not available. The other strategy was a drop-off/pick-up, self-administered strategy. The telephone/field strategy was shown to be a viable alternative to in-person interviewing. The drop-off/pick-up strategy did not fare as well in comparison. Although response rates and costs were equivalent to in-person interviewing, the process was less enjoyable for respondents, and produced significantly different distributions on several sensitive measures.
