About this study
Official title: Efficacy of Adjunct Sleep Interventions for PTSD
The purpose of this research study is to evaluate and compare the effects of experimental treatments aimed at improving insomnia and nightmares in men and women military veterans between the ages of 18 and 60 years old, and who have a condition called Posttraumatic Stress Disorder. Insomnia refers to difficulty falling or staying asleep, although enough time is allowed for sleeping. Insomnia is also associated with daytime consequences, such as lack of energy, irritability, and difficulty concentrating. Nightmares are bad dreams that may or may not awaken the sleeper, and that cause discomfort during the daytime.
Chronic Posttraumatic Stress Disorder (PTSD) refers to symptoms that occur after someone experienced or witnessed a life-threatening event, and that persist for three months or more after the event. Symptoms include flashbacks, nightmares, feelings of detachment from others, sleep disturbances, irritability, anxiety, and efforts to avoid people and places associated with the life-threatening event. These symptoms occur after a life-threatening event. Symptoms that persist for more than one month indicate the presence of PTSD. In the present study, we will study people with chronic PTSD, which refers to PTSD symptoms that persist for more than 3 months.
Efficacy of a treatment is defined as the capacity to produce the desired effects. In this study, we will evaluate and compare the capacity of two active experimental treatments to reduce insomnia and nightmares associated with PTSD, and one inactive intervention, called a placebo, for people who continue to have sleep difficulties despite receiving treatment with an antidepressant medication called a selective serotonin reuptake inhibitor (SSRI, like Prozac, Paxil, Zoloft, Celexa). The two active experimental treatments are a medication, prazosin, and a brief behavioral intervention, which involves exercises and techniques to reduce nightmares and improve sleep quality. Prazosin is an approved medication by the Food and Drug Administration (FDA) against high blood pressure, but is not FDA-approved for posttraumatic insomnia and nightmares.
Read the detailed description
Posttraumatic stress disorder (PTSD) is a prevalent disorder in military samples associated with adverse emotional and health impacts and enormous health care costs, and it is often resistant to treatment. Identification of PTSD-related factors that contribute to poor clinical and health outcomes is imperative to refine treatment strategies. Post deployment -related sleep disturbances constitute one of the factors that contribute to poor clinical and health outcomes. PTSD symptoms persist during sleep, but little clinical attention is typically devoted to nighttime symptoms. Other deployment related stress reactions are associated with sleep disturbances. Sleep disturbances are resistant to traditional PTSD treatments. There is emerging evidence that adjunct sleep-focused interventions (pharmacological or behavioral) are associated with improvements in sleep, daytime symptomatology, general emotional well being, and functioning. Therefore, sleep focused interventions may enhance treatment response and clinical outcomes in individuals exposed to trauma with consequent sleep disturbances. However, the efficacy and durability of adjunct sleep interventions have not been formally evaluated and compared. In this study, we aim at comparing the efficacy and durability of interventions targeting sleep disturbances that occurred in relation to military service and or military deployment.
The overarching objective of this study is to investigate and compare the efficacy and durability of adjunct sleep-focused interventions on sleep, daytime PTSD symptomatology, and mood in a sample of 90 male and female veterans who experience nightmares and insomnia. The specific aims and hypotheses are: 1. To investigate the efficacy of prazosin, integrated behavioral sleep intervention (IBSI), and placebo (PLA) on post deployment-related sleep disturbances; 2. To compare the efficacy of pharmacological and behavioral interventions adjunct sleep focused interventions; 3. To evaluate and compare the durability of active sleep-focused interventions on sleep, daytime PTSD symptoms, mood, and anxiety by conducting a naturalistic follow-up assessment 4 months after the end-of-treatment assessment. A secondary aim is to identify demographic, psychosocial, and clinical predictors of sleep treatment response in military veterans.
Participants will be recruited from the Pittsburgh VA Health Care System clinics and services. Treatments will be administered over an eight-week period for all conditions. Primary outcome measures include (1) Sleep Quality as determined by polysomnographic (sleep) recordings, and global scores on the Pittsburgh Sleep Quality Index (PSQI) and PSQI Addendum for PTSD (PSQI-A). Sleep response will be defined as a sleep latency < 30 minutes, and wake time after sleep onset < 30 minutes, and a sleep efficiency > 85% as determined by sleep diaries and in-home sleep studies, or a decrease in > 5 points on the Pittsburgh Sleep Quality Index. Secondary outcome measures include PTSD symptom severity as determined by the Clinician-Administered PTSD scale, Part 2, and the self-report PTSD Symptom Checklist-Military version; depression severity (as determined by the Beck Depression Inventory) anxiety (Beck Anxiety Inventory), (4) health-related quality of life (SF-36). A naturalistic follow-up assessment will be conducted four months post-treatment.
The proposed study will contribute to the development of effective therapeutic strategies for PTSD. This study will provide novel information regarding predictors of sleep treatment response in PTSD, which will contribute to facilitating care management in PTSD.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Behavioral Sleep InterventionBehavioural
Also called Behavioral Intervention for Insomnia and Nightmares
Participants will receive a workbook with information related to the intervention. The three core components are presented and discussed during these sessions are:1) education about sleep and nightmares; 2) imagery rehearsal; 3) stimulus control and sleep restriction. Session 1 focuses on education on PDSD-related insomnia, nightmares, and sleep avoidance behaviors. The rationale for imagery rehearsal will then be presented, and the technique will be practiced once. Strategies for managing intrusive thoughts and images during the practice of imagery rehearsal will be discussed. Participants will be instructed to practice this technique at least three times each day for the duration of the treatment phase. During the second 45-minute session (Week 3), sleep schedules extracted from the pre-intervention sleep diary will be used to identify goals to reduce insomnia, i.e., for sleep restricted schedules, and activities to be performed out of bed when awake.
PrazosinDrug
Also called MINIPRESS®, Vasoflex®, Hypovase®,
Participants randomized to PRZ will take 4 capsules each night (PRZ dose complemented with placebo capsules ). The target dose of prazosin is 10 mg. Some individuals may require doses up to 15 mg, (Murray Raskind, M.D., personal communication, February 4, 2005). Prazosin will be administered in an initial oral dose of 1 mg (Week 1), with titration to a maximum of 15 mg. The first increment will be of 1 mg (Week 2: 2 mg), and subsequent weekly increments according to the following schedule: Week 3: 4 mg; Week 4: 6 mg; Week 5: 10 mg; Week 6: 15 mg; Week 7: 15 mg; Week 8: 15 mg. A maximum dose of 15 mg may be necessary. Medication will be administered in a single dose to be taken 30 minutes prior to bedtime because the onset of action occurs within 30 to 90 minutes after a single dose.
PlaceboDrug
Also called Sugar pill
Participants randomized to PLA will take 4 capsules each night for eight weeks, all capsules will be identical to prazosin capsules. As for participants randomly assigned to PRZ, they will receive a one-week medication supplies in daily dose dispensers. Similarly, participants will also be instructed to be ready for bed at the time they take the medication, and not to engage in any activities that will prevent them from going to bed.
| Study group | Role | What they receive |
|---|---|---|
| Medication | Active comparator | Treatment will be conducted under double blind conditions and will last a total of 8 weeks. Participants will also receive printed educational material about sleep hygiene developed by the American Academy of Sleep Medicine. Items include going to bed when drowsy, avoiding clock watching while awake in bed, avoidance of caffeine and alcohol, engaging in moderate exercise, and ensuring comfortable sleep environment. Clinical ratings will be obtained weekly throughout the trial.Medications will be administered in a single dose to be taken 30 minutes prior to bedtime because the onset of action occurs within 30 to 90 minutes after a single dose. The research pharmacy will prepare each dose in identical gelatin capsules to prevent identification. Receives: Drug: Prazosin |
| Behavioral | Active comparator | Participants randomized to BSI will receive the intervention aimed at reducing nightmares, insomnia, and sleep avoidance behavior. The treatment will be administered over 8 weeks. The intervention sessions will consist of two individual, 45-minute treatment sessions, delivered on Weeks 1 and 3. A 45-minute "booster" session will be conducted on Week 5. Thirty-minute face-to-face contacts will be scheduled on other weeks (i.e., Weeks 2, 4, 6, 7 and 8) to address any difficulty with the treatment instructions and techniques, to answer questions that may have occurred, and to complete weekly clinical ratings (CGI-I/SR and ASES). Receives: Behavioral: Behavioral Sleep Intervention |
| Placebo | Placebo comparator | Participants randomized to PLA will take 4 capsules each night, and capsule will be identical to prazosin capsules. As for participants randomly assigned to PRZ, they will receive a one-week medication supplies in daily dose dispensers. Similarly, participants will also be instructed to be ready for bed at the time they take the medication, and not to engage in any activities that will prevent them from going to bed. A placebo pill condition is included for several reasons. First, there is no approved treatment approach currently recognized as being effective for sleep disturbances associated with combat-related PTSD, and which is being withheld from subjects assigned to the placebo arm of the study. We will monitor subjects carefully and on a weekly basis. Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Insomnia Severity Index
Self-report measures of insomnia severity. Scores range from 0 to 28, with higher scores indicated more severe insomnia. A score < 8 is considered to reflect no significant insomnia.
Measured: Screening, Post, and Follow-up
Sleep Diary Measures
Sleep diary SE, nightmare frequency Sleep diary sleep efficiency can range from 0 to 100%, and typically varies between 50% and 95%. Higher % values reflect greater sleep consolidation, i.e., greater ratio of time asleep/time in bed.
Nightmare frequency varies between 0 and no upper limit is provided. Greater frequency of nightmares reflects greater nightmare severity.
Measured: baseline and post
PSG Composite Measure
Sleep Efficiency (SE) is the ratio of total time spent asleep over total time spent in bed.
For PSG studies, (SE) typically vary between 50% and 95%. Greater values indicated more consolidated sleep.
Measured: Baseline sleep study and post sleep study
PSQI
Self-report sleep quality measure. Scores range between 0 and 21, with higher scores reflecting poor sleep quality.
A score of < or = to 5 reflects good sleep quality.
Measured: Baseline, post, 4 months post-treatment
