There are a myriad of incentives types that can be used to increase response rates and Nielsen has tested several types in the past five years in trying to increase response rates in its Diary measurement service. These include incentives given prior to making contact to recruit a HH, incentives sent with the diary packet, and incentives given in the middle of the diary week. This presentation will review the results of many nation experiments Nielsen has conducted on these types of incentives.
