Open Pilot of Cognitive Behavioural Therapy for Insomnia in Pregnancy

September 13, 2018 updated by: Lianne Tomfohr-Madsen, University of Calgary
Despite the literature showing cognitive behavioural therapy for insomnia (CBT-I) to be effective in a variety of populations including postpartum women, as well as the demonstrated harmful consequences of sleep disturbances in late pregnancy, no trials have investigated its efficacy during pregnancy. This project will investigate the efficacy and acceptability of cognitive behavioral therapy for insomnia (CBT-I) in pregnancy.

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.

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.

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
Change in Actigraphy indices from baseline to post-treatment
Time Frame: Baseline (Week 1), Post-treatment (Week 7)
Actigraphy is recommended as a reliable and useful method of objective sleep assessment, providing information about indices of sleep efficiency, sleep latency, total sleep time, and number and frequency of awakenings
Baseline (Week 1), Post-treatment (Week 7)
Change in Sleep Diary variables from baseline to post-treatment
Time Frame: Baseline (Week 1), Treatment (Weeks 2-6), Post-treatment (Week 7)
Participants complete a daily, standardized sleep diary on a weekly basis both during the treatment period, and at baseline and final assessment times to corroborate actigraphy data. Dependent variables derived from this data include total sleep time, time in bed, sleep efficiency, and sleep quality
Baseline (Week 1), Treatment (Weeks 2-6), Post-treatment (Week 7)
Change in Insomnia Severity Index (ISI) scores from baseline to post-treatment
Time Frame: Baseline (Week 1), Post-treatment (Week 7)
The ISI can be used to assess the severity of sleep onset, sleep maintenance and early wakening problems, sleep dissatisfaction, and one's perceived distress caused by sleep problems. Scores on the ISI range from 0 to 28, with scores ≥ 15 indicating clinical insomnia.
Baseline (Week 1), Post-treatment (Week 7)
Change in Pittsburgh Sleep Quality Index (PSQI) scores from baseline to post-treatment
Time Frame: Baseline (Week 1), Post-treatment (Week 7)
The PSQI instrument is used in assessing one's sleep quality in the preceding month. It is comprised of 19 self-rated items and 5 questions rated by the roommate or bed partner. The PSQI possesses seven components: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medications and daytime dysfunction. PSQI scores range from 0 to 21, with scores greater than 5 indicating poor sleep quality.
Baseline (Week 1), Post-treatment (Week 7)

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
Change in Edinburgh Postpartum Depression Scale (EPDS) scores from baseline to post-treatment
Time Frame: Baseline (Week 1), Post-treatment (Week 7)
The EPDS serves as a valuable and efficient way of identifying women at risk for prenatal depression, and can be used for screening both anxiety and depressive symptoms
Baseline (Week 1), Post-treatment (Week 7)
