Table 1. Burden, Incentive, and Response Rates in Federal Studies with Multiple Data Collection Formats (Compiled by Laura Wiese, MPH, University of Georgia).

Study Name/Agency	Year	Study description	Respondent burden	Incentive	Response rate
Third National Health and Nutrition Examination Survey (NHANES III)/ CDC/NCHS http://www.cdc.gov/nchs/nhanes.htm	1988-1994	NHANES was designed to collect information about the health and diet of people in the United States to provide current statistical data on the amount, distribution, and effects of illness and disability in the United States.	In-person interview, medical examination	$230 (plus exam results)	Interview= 82% Exam=73%
National Human Exposure Assessment Survey (NHEXAS) Region 5/ EPA http://cfpub.epa.gov/ordpubs/nerlpubs/recordisplay.cfm?deid=64969	1995-1997	A population-based pilot study of the exposure to metals, pesticides, volatile organic compounds, and other toxic chemicals of ~500 people in 3 US regions.	Questionnaires, video-taped observations, duplicate diet samples, collection of blood and urine, measurements of air quality and soil and dust in and around the home	$195	Questionnaire = 71.5% Visit 1 = 80% Visit 2 = 56.8% Visit 3 = 47.8%
Minnesota Children's Pesticide Exposure Study (MNCPES)/ EPA http://www.ncbi.nlm.nih.gov/pubmed/10791596	1997	Study of multi-pathway and multi-pesticide exposures in children. The primary objective was to characterize children's exposure to selected pesticides through a combination of questionnaires, personal exposure measurements and monitoring of biological samples, environmental samples, and children's activity patterns.	4-day duplicate diet samples, 6-days of personal air monitoring, keeping time and activity diaries, blood, urine and hair collections, videotaping.	$195 (children given age-appropriate gifts and parents offered videotapes of their children)	Telephone Screening = 67.5%
School Health Initiative: Environment, Learning, Disease Study (SHIELD)/ EPA No website available	1999	School-based investigation of children's environmental health in economically disadvantaged urban neighborhoods of Minneapolis.	Health questionnaires, 48-hour VOC sampling, blood draw, vacuum sampling in home, urine collections, school records review	$140 (children given age-appropriate gifts)	Recruitment= 56.7% (interviews/data collections ranged from 76-88%)
Biologic Specimen-based Study of Dietary Measurement Error/ NCI No website available	1999	This study assessed dietary measurement error by comparing energy and protein intakes from two self-reported dietary data collection instruments (the NCI Diet History Questionnaire and the in-person 24-hour dietary recall interview) with two biomarkers (doubly labeled water and urinary nitrogen excretion)	Three clinic visits. Dietary History Questionnaire, 24-hour dietary recall, height/weight measurements, physical activity questionnaires, urine collection, Doubly-labeled water dose, 24-hour urine collection	$200	Telephone recruitment=79% Visit=100% (5 and 2 hours)
