Effects of alternative follow-up procedures on mail survey response rates

Abstract

Compared the effects on response rate by 700 consumers included in a large-scale mail survey of (a) not sending a follow-up letter, (b) sending a follow-up letter with a duplicate questionnaire and return envelope, and (c) sending a follow-up letter without duplicates. Results suggest that the best method is a follow-up without duplicates. (20 ref) (PsycInfo Database Record (c) 2025 APA, all rights reserved)
