Further study details as provided by Pfizer:

Primary Outcome Measures:

Once subjects identified, a series of focus group sessions will be held to identify concepts, themes and items relevant to Nonrestorative Sleep. [ Time Frame: monthly ] [ Designated as safety issue: No ]
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. [ Time Frame: nightly ] [ Designated as safety issue: No ]
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)]. [ Time Frame: nightly ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

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. [ Time Frame: nightly ] [ Designated as safety issue: No ]
Secondary assessments to characterize the functional impact of insomnia including Nonrestorative Sleep include additional PSG (polysomnography) variables. [ Time Frame: nightly ] [ Designated as safety issue: No ]
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. [ Time Frame: monthly ] [ Designated as safety issue: No ]

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