The 2000 Sleep Cohort Study Survey was a mail survey of approximately 5000 former and current Wisconsin state employees. The 5 wave, 8 page mail out survey instrument asked questions about general health, and sleep behaviors and problems. Results of the survey will contribute to understandings of sleep and changes in sleep patterns over time.
