Objectives
The National Sleep Foundation commissioned WB&A Market Research to conduct a national survey of adult Americans who work at least
30 hours per week for pay – the NSF 2008 Sleep in America poll.
The primary objectives of this research were to answer the following questions:
1. What are the sleep habits of working Americans?
2. How do hours worked affect both sleep and ability to function while awake?
3. How do sleep habits and problems affect performance in the workplace?
4. How many working Americans experience various types of sleep problems/disorders?
5. How often do working Americans experience sleep problems/disorders?
6. How do working Americans cope with sleepiness?
7. How does sleepiness affect the personal lives of working Americans?
NSF wishes to acknowledge the volunteer work of the members of its 2008 Poll Task Force. In appreciation of Task Force members: Dr.
Thomas J. Balkin, (Co-Chair) Dr. Gregory Belenky (Co-Chair), Dr. Christopher Drake, Dr. Roger Rosa, and Dr. Mark Rosekind.

Consulting, Inc. and quotas were established by region.
Professional interviewers called from WB&A’s telephone
interviewing facilities located in Crofton, Maryland and Ithaca, New
York. Most of the interviewing was conducted on weekdays
between 5:00 pm and 9:00 pm, Saturdays between 10:00 am and
2:00 pm, and Sundays between 4:00 pm and 8:00 pm. The
remaining interviews were conducted on weekdays between 9:00
am and 5:00 pm. (All times are in Eastern Standard Time.)
In survey research, the entire population is typically not interviewed,
but rather a sample of that population is polled. Therefore, the data
are subject to sampling error. The maximum sampling error of the
data for the total sample of 1,000 interviews is
3.1 percentage
±
points at the 95% confidence level. The sampling error will vary
depending on the sample size and the percentages being examined
in the sample.
The response rate for this study was 17% (number of completed
interviews divided by the number of completed interviews plus the
number of contacted households who refused participation or did
not complete appointments, factored by the overall incidence of
71%). As might be expected with working Americans, the response
rate for this year’s poll was slightly lower than in previous years
(ranging from 20%-27% in the past three years).
Note when reading this report: Percentages may not add up to
100% due to rounding.
