Outcome Measures
Primary Outcomes (3)
Once subjects identified, a series of focus group sessions will be held to identify concepts, themes and items relevant to Nonrestorative Sleep.
monthly
To begin to refine the development of the RSQ measure in subjects with Nonrestorative Sleep by generating item content pertaining to morning refreshment and uncovering problems in instrument administration in subjects with nonrestorative sleep.
nightly
Identification of subjects with insomnia characterized by Nonrestorative Sleep only [assessed via LPS (latency to persistent sleep onset) and WASO (Wake after sleep onset) as determined by PSG (polysomnography)].
nightly
Secondary Outcomes (3)
Subjective measures include MAF (multidimensional assessment of fatigue), Sheehan Disability Scale, SF36v2, Endicott Work productivity scale (EWPS) Global impression of severity (CGIS) and the Profile of mood states.
nightly
Secondary assessments to characterize the functional impact of insomnia including Nonrestorative Sleep include additional PSG (polysomnography) variables.
nightly
After phase IIa of this study, a questionaire to be designed - Participants to be debriefed, and interviewed to assess the content validity of the questionnaire.

Interventions
PSG (polysomnography) for adaptation night, day 2 evening, and day 3 evening--used to identify suitable Nonrestorative Sleep candidates to participate in focus groups.
