Read Carefully Before Using
The EPA does all it can to ensure that the identity of survey participants cannot be disclosed. All direct identifiers, as well as any characteristics that might lead to identifications, are omitted from the data. Any intentional identification or disclosure of a person or establishment violates the assurances of confidentiality given to the providers of the information. Therefore, users will (1) use the data in this study for statistical reporting and analysis only; (2) make no use of the identity of any person or establishment discovered inadvertently and will advise the HEDS Administrator of any such discovery; (3) will not link this data with individually identifiable data from other EPA or non-EPA data.
By using the data you signify your agreement to comply with the above-stated statutorily based requirements.
CTEPP STANDARD OPERATING PROCEDURE FOR TELEPHONE SAMPLE SUBJECTS RECRUITMENT (SOP-1.12).
The CTEPP study is the largest aggregate exposure study of preschool children (ages 2 to 5 years) conducted in the United States. The CTEPP study was designed in part to fill in critical data gaps on young children’s exposures to pesticides in response to the Food Quality Protection Act (FQPA) of 1996.
The subject recruitment procedures for the telephone sample component are described in the SOP. A random telephone sample list is ordered from a commercial survey sampling firm. Using this list, introductory letters are sent to targeted homes prior to making initial telephone contacts. Follow-up calls using standardized telephone scripts begin five days after the mailing of the letters. A Computer Assisted Telephone Interview (CATI) system is developed to facilitate the recruitment screening process. Initial telephone contact includes screening and a brief interview. To ensure participation of each eligible family, a follow-up visit and multiple follow-up calls are conducted. The final participants are randomly selected from all households who are willing to participate.
