From page 60...
... Considerations affecting data quality are: • Response rates -- Response rates affect the amount of nonresponse error, which arises from the possibility that those not completing a survey would have answered differently than those who did complete a survey. Response rates are affected by a broad range of factors including the enthusiasm and diligence of survey workers who distribute questionnaires or conduct interviews, the level of rider interest, whether selfadministered surveys or personal interviews are used, length and complexity of the questionnaire, use of incentives, and the frequency of surveys being conducted.

... The research should formulate and test different questionnaire designs and different incentive levels to measure the affects of these factors on response rates, item nonresponse, and, for origin and destination information, the quality of address and trip information. Alternative designs could also be tested to determine the impact of questionnaire length, use of matrixes, and use of horizontal versus vertical lists of answer choices.
