Increasing Response Rates to Mail Questionnaires: Effects of Incentives and Certified Mail.
Abstract
Two experimental manipulations were undertaken to improve the response rate to questionnaires mailed to Navy enlisted men who were joining the Fleet Reserve after twenty years of service. In a two by two design we studied the effects of giving $1 incentive payments and using certified mail. The data showed that incentives sharply increased response rate, in one mailing from 17% to 34%, but that certification had no effect. Explanations of the beneficial effect of incentives and the ineffectiveness of certified mail are discussed. (Author)
