Interactive Effects of Major Response Facilitators
研究了邮寄调查中多种应答促进技术是否独立作用，通过分析531项独立研究，发现它们之间存在显著的交互效应，对提高应答率有联合影响。
ABSTRACT Practitioners and researchers have long been interested in achieving the highest response rate within resource constraints on their mailed surveys. Achieving this high response rate typically has required the selection of the right mix of response‐facilitating techniques. The selection decisions were generally made under the assumption that the response‐facilitating techniques act independently of one another. The authors have examined the validity of this independence assumption by identifying the major response facilitators in use and then analyzing the results of 531 independent mail survey studies. The authors conclude that major facilitators do not function independently. In fact, it was found that significant joint action interactive effects on response rates do exist. Practitioners and researchers who are faced with the survey design decisions of choosing response facilitators can receive assistance by reviewing the results of this diverse collection of reported experiences.
