Comparison of Two Techniques to Obtain Information on Pesticide Use from Iowa Farmers by Interview
Author: Blair, Aaron
Date Published: 1997
A methodological study was conducted in Iowa to evaluate the quality of information on pesticide use provided by farmers and their spouses. Included in this project was an assessment of the amount of detail farmers could provide in interviews regarding agricultural use of pesticides and to evaluate whether a volunteer or probe interviewing technique elicited the best response. Results indicate that questionnaires based on an approach where farmers volunteered the names on individual chemicals used, i.e., provided names without interviewer prompts are likely to be less complete.
