Study Type : Observational
Actual Enrollment : 64 participants
Official Title: Refinement Of Patient Reported Outcomes Instruments In Subjects With Insomnia Characterized By Nonrestorative Sleep
Study Start Date : August 2008
Actual Primary Completion Date : January 2009
Actual Study Completion Date : January 2009

Group/Cohort Intervention/treatment
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.

Primary Outcome Measures :
  1. 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 ]
  2. 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 ]
  3. 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 ]

Secondary Outcome Measures :
  1. 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 ]
  2. Secondary assessments to characterize the functional impact of insomnia including Nonrestorative Sleep include additional PSG (polysomnography) variables. [ Time Frame: nightly ]
  3. 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 ]
