INSTRUCTIONS & DEFINITIONS

Note that the signup questions that you get first are not the survey! Part of the signup process with AltaVoice involves answering two pages of demographic questions like age, gender, race, etc. This is not our survey. After you've finished signing up you will be taken to our survey, called "Circadian Rhythm Sleep Disorders", which asks about your circadian disorders, sleep habits, treatment, and other disorders. Our survey has multiple pages. The actual number is dependent on how you answer some key questions. Please be sure to complete the entire survey. Otherwise, your responses will not be used in analysis.

If you're wondering whether you have in fact completed the survey, you can see by clicking on "Profile" at the top of the survey home page. Your profile shows which surveys you have completed. We are interested in the Circadian Rhythm Sleep Disorders survey.

INSTRUCTIONS

DEFINITIONS:

Delayed Sleep Phase Disorder (DSPD). Sleep occurs later than desired, but usually at around the same time every day (within a few hours). To get enough sleep, one needs to sleep late into the morning or afternoon. Waking up earlier is difficult. The body is resistant to shifting the schedule earlier with the usual sleep hygiene methods. (Other names include Delayed Sleep Phase Syndrome (DSPS), Circadian Rhythm Sleep Disorder – Delayed Phase Type, and similar.)

Non-24-Hour Sleep-Wake Disorder (Non-24). Sleep occurs later and later each day, progressing all the way around the clock. In some persons living on a 24 hour schedule, Non-24 may present as periods of insomnia recurring at regular intervals over weeks or months. (Other names include Free Running Disorder, Hypernychthemeral Syndrome, Circadian Rhythm Sleep Disorder – Free Running Type, and similar.)

Advanced Sleep Phase Disorder (ASPD). Sleep occurs earlier than desired, and the sleeper has difficulty staying up in the evening and wakes up very early. (Other names include Advanced Sleep Phase Syndrome (ASPS), Circadian Rhythm Sleep Disorder – Advanced Phase Type, and similar.)

Irregular Sleep-Wake Disorder (ISWD). Sleep is not regular, and generally there are multiple sleep periods each day. (Other names include Circadian Rhythm Sleep Disorder – Irregular Type, and similar.)

Circadian Rhythm Sleep Disorder (CRSD). Any of the above four disorders. (Also Circadian Rhythm Disorder (CRD))

We are not surveying shift work disorder, which likely has different underlying causes.
