You may be eligible if
a complaint of persistent (i.e., \> 1 month) difficulties initiating or maintaining sleep despite adequate opportunity for sleep;
a sleep onset latency or wake time after sleep onset \> 30 minutes 3 or more nights per week during two weeks sleep diary monitoring;
an Insomnia Severity Index (ISI) score \> 10 indicating at least "mild" insomnia; and
a score ≥ 2 on either the interference or distress item of the screening ISI, indicating the insomnia causes significant distress or impairment in social, occupational, or other areas of functioning. These criteria represent those provided in the DSM-IV-TR87, Research Diagnostic Criteria3 and the International Classification of Sleep Disorders4, and will ensure a sample with clinically relevant insomnia.
You may not be if
an untreated psychiatric disorder (e.g., major depression) as these conditions have specific treatments and it would be inappropriate not to offer those treatments;
a lifetime diagnosis of any psychotic or bipolar disorder as sleep restriction and medications for insomnia may precipitate mania and hallucinations;
an imminent risk for suicide;
alcohol or drug abuse within the past year, since BzRAs are cross-tolerant with alcohol;
terminal or progressive physical illness (e.g., cancer, COPD), or neurological degenerative disease (e.g., dementia);
current use of medications known to cause insomnia (e.g., steroids);
sleep apnea (apnea/hypopnea index \> 15), restless legs syndrome, periodic limb movement during sleep (PLMS with arousal \> 15 per hour), or a circadian rhythm sleep disorder (e.g., advanced sleep phase syndrome);
habitual bedtimes later than 2:00 AM or rising times later than 10:00 AM;
consuming \> 2 alcoholic beverages per day on a regular basis.
Individuals using sleep-aids (prescribed or over-the-counter) will be included if they are willing and able to discontinue medications at least 2 weeks before baseline assessment. Participants using alcohol as a sleep aid or alcohol after 7:00pm on a regular basis will be required to discontinue this practice at least two weeks prior to baseline assessment. Individuals using psychotropic medications (e.g., anxiolytics, antidepressants) will not be automatically excluded from the study. Those on stable dosages (for at least three months) of SSRI or SNRI medications and who show at least partial remission (via SCID) from their mood or anxiety disorder will be accepted in the study if they meet the selection criteria above. Patients using TCAs, MAOIs, or atypical antidepressants will be excluded even if in remission as the effects of these medications on sleep might confound interpretation of the findings. We will impose similar standards for those with MDD, dysthymia, panic disorder, phobia, and GAD. We realize that some decisions about enrollment may not always be easy to make, but we will rely on all available data and a consensus approach to guide our clinical decision making process
