NOTE: The statements have been reworded and a few additional factors have been added.
Questionnaire-related - The questionnaire should:
(1) be well-designed, with a clear focus and purpose
(2) have simple layout
(3) be kept concise
(4) have clear instructions for completion
(5) be thoroughly piloted and tested prior to use
(6) be written to hold the subject's attention
(7) be appealing to look at (looks professional)
(8) easily navigated, with the status of completion clearly indicated
Responder-related - The subjects should:
(1) be notified in advance about the study with a personalised invitation.
(2) feel like they are actively involved in the study or may benefit from its findings.
(3) be offered an incentive to complete and return the survey.
Delivery-related:
(1) A researcher is available to answer questions.
(2) The researcher should look nice (or sound nice, if reached by phone).
(3) The testing environment should look appealing, without distractions.
(4) Collection is as complete as possible:
(4a) If administered directly, the researcher collects the form as the subject leaves.
(4b) If response is by mail, a pre-addressed and stamped envelope is included.
(4c) Completed electronically if appropriate.
It is important to make sure that attempts to increase the response rate do not introduce bias into the results:
(1) by excluding persons with certain disabilities
(2) by offering greater rewards for certain responses
(3) by using terms understood by a minority of respondants
