Abstract:Results are presented of an experiment designed to investigate the effects of certified and first-class mail on final response and refusal rates in a mixed-mode survey of next-of-kin respondents. The use of certified mail did produce an initial higher response rate, although after followup with telephone and in-person interviews the final response rate was not higher for the certified mail group. Moreover, refusal rates were significantly higher for the group sent certified mail. The use of certified mail did, however, lower overall survey costs.
Keywords:Mail survey; mixed-mode survey; next-of-kin respondents.
