Primary Outcome Measures:
  • Sleep Onset Latency [ Time Frame: Baseline, Post treatment, 3 month follow up ]
    Daily assessment of sleep and daytime functioning (daily voice mail sleep diary and actigraphy) for 10 weeks: 2 weeks prior to and after treatment and during the 6 week treatment period. The primary sleep outcomes will be improvement in sleep onset latency (SOL) and total sleep time (TST).

Secondary Outcome Measures:
  • Dim Light Melatonin Onset [ Time Frame: Baseline, post treatment ]
    Assessment of circadian melatonin phase 2 weeks prior to and 2 weeks after treatment(dim light melatonin onset—DLMO, 2 weeks prior to treatment and 2 weeks post treatment assessment of quality of life (SF-36) and sleep quality (Pittsburgh Sleep Quality Index—PSQI), 2 weeks prior to treatment and 2 weeks post treatmemnt daily assessment of daytime functioning.

Ages Eligible for Study:   18 Years to 64 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Medical and sleep/wake history. During the screening process, participants will receive a physical exam, urine and blood labs, and be interviewed about their medical and sleep/wake history and be asked questions about their present and past habitual sleep/wake schedule and nap times.

    (b) Medication/drug/alcohol use. Participants must have no history of drug or alcohol abuse or dependency, consume no more than 2 alcoholic beverages a day or more than 14 per week, Participants must agree not to consume more than 2 beverages containing caffeine (caffeinated coffee, tea, colas) a day before 2 pm and none after 2 pm.

    (c) Evaluation of Psychiatric/Psychological Suitability. Participants must demonstrate a full understanding of the requirements and demands of the study.

For inclusion/exclusion screening, participants will receive a sleep, medical, physical and psychiatric history examination, one-night of dim light melatonin onset evaluation in the sleep laboratory, one-night of polysomnography, and two weeks of baseline sleep assessment. If during the polysomnography assessment the participant had a respiratory disturbance index (RDI) of 15 or more, the participant would be considered to have met the exclusionary criterion for obstructive sleep apnea. A letter providing feedback of the all night polysomnography assessment will be sent to all participants.

Individuals with a history of psychiatric illnesses or psychiatric disorders will be excluded, such as but not limited to, alcoholism, drug dependency, mood disorders; schizophrenic disorders, anxiety disorders; personality disorders. Finally, individuals who are unaware of specific psychiatric diagnoses who have a history of having been treated with antidepressants, neuroleptic medications or major tranquilizers will be excluded from study. However, a personal history of limited prior counseling or psychotherapy (e.g., for adjustment reactions) will not be exclusionary. Individuals who have been treated for insomnia within the past six months will be excluded.

Exclusion Criteria:

  • Exclusion criteria include diagnosis or treatment of other sleep disorders such as obstructive sleep apnea, narcolepsy, sleep walking, and periodic limb movement disorders. Participants with a history of night work in the preceding 6 months or transmeridian travel (across >3 time zones) in the last 1 month prior to the study will be excluded.

Use of psychotropic, hypnotic medications known to affect sleep or contraindicated for use with ramelteon, or over-the-counter analgesics that contain caffeine, or herbal supplements, including products with herbs, melatonin, or St. John's Wort.

Substance use will be determined by self-report and urine toxicology during the screening visit. Women who are pregnant or are planning on becoming pregnant will be excluded from the study. Female participants will be given a pregnancy test during the screening process.
