Treatments for Insomnia: Mediators, Moderators and Quality of Life

September 18, 2019 updated by: Jerome Yesavage, Palo Alto Veterans Institute for Research
The purpose of this study is to evaluate the relative efficacy and effectiveness of specific components of cognitive behavioral therapies for insomnia: sleep restriction (SR) and cognitive therapy (CT) in comparison to combined SR and CT (SR+CT).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

As many as one in three older adults may experience insomnia. Older adults are the most frequent users of hypnotic medications. Although safer, use of even the latest "sleeping pills" can lead to cognitive impairment and risk of falls. Thus, it is not surprising that non-pharmacological treatments for insomnia have been pursued as alternatives to medications, with some suggesting they should be the "first line of therapy". We propose a randomized clinical trial to evaluate the relative efficacy and effectiveness of specific components of cognitive behavioral therapies for insomnia (CBT-I): sleep restriction (SR) and cognitive therapy (CT) in comparison to combined SR and CT (SR+CT). We hypothesize that because the proposed mechanisms of action of CT versus SR substantially differ, their combination may have additive effects. Even though the mechanisms of action of SR and CT may differ, no data exists to document that the addition of one to the other provides more overall clinical benefit than either intervention alone. Finally, to better understand "how" and "in whom" SR and CT work, we plan to formally evaluate selected mediators and moderators of the clinical effect including physiological measures of anxiety and arousal. Three treatments (SR, CT, and SR+CT) will be compared in a randomized clinical trial with a parallel groups design. Efficacy and effectiveness data will be collected prior to the beginning of treatment, after 6 weeks of treatment, and at the end of a 6-month follow-up. These efforts follow the National Institute of Mental Health Strategic Plan Strategy 3.1 to develop innovative interventions and designs for intervention studies, in this case, to promote a new intervention trial that focuses on the mediators and moderators of treatment response.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Experimental: Cognitive Behavioral Therapy
Cognitive Behavioral Therapy is designed to identify incorrect ideas about sleep, challenge their validity, and replace them with correct information. This therapy tries to reduce worry, anxiety, and fear that one won't sleep by providing accurate information about sleep.
Behavioral: Cognitive Behavioral Therapy
Cognitive Behavioral Therapy is designed to identify incorrect ideas about sleep, challenge their validity, and replace them with correct information. This therapy tries to reduce worry, anxiety, and fear that one won't sleep by providing accurate information about sleep.
Experimental: Sleep Restriction
Sleep Restriction therapy will limit the time participants spend in bed in order to make sure they are sleepy enough to fall asleep quickly.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Insomnia Severity Index
Time Frame: Screening, End of 6-week treatment, 6-month follow-up
Subject's subjective evaluation of their sleep.
Screening, End of 6-week treatment, 6-month follow-up

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Cognitive Arousal
Time Frame: Screening, end of 6-week treatment, 6-month followup

Score on Penn State Worry Questionnaire, and Dysfunctional Beliefs and Attitudes about Sleep Scale.

Both measures have been found to be successful in measuring mediators and moderators of treatment response.
Screening, end of 6-week treatment, 6-month followup
Chronic Stress
Time Frame: Screening, end of 6-week treatment, 6-month followup
We are using two of the most widely utilized psychometric indices of past, present and chronic stress exposure: 1) the Trauma History Questionnaire, and 2) the Life Stressor Checklist revised, a clinical interview for lifetime exposure to stressful life events.
Screening, end of 6-week treatment, 6-month followup
