- Brief Summary
Insomnia is one of the most common complaints among service-members and Veterans of recent military conflicts. Insomnia has been shown to play a causal role in mental health, hypertension, obesity, and other health conditions, increasing risk for all-cause mortality. Cognitive-Behavioral Therapy for Insomnia (CBTI) produces both short-term and sustained resolution of insomnia with fewer adverse side effects than medications, but access to behavioral sleep medicine expertise within the VA is very limited.
The proposed study is compares Tele-Self CBTI to Health Education Control for improved insomnia severity among treatment-seeking Veterans with Insomnia. In this study, 200 participants will be randomized with a 50/50 chance for either Tele-Self CBTI or a Health Education Control condition. Eligible participants are Veterans who are: a) prescribed sleep medications; b) diagnosed with insomnia; and/or c) referred for clinic-based CBTI (but not yet treated) for insomnia. Participants will be identified using electronic health records (EHR) and telephone interviews.
Participants' sleep will be assessed at three time points, at Baseline, 8 weeks and 6 months after Baseline. Tele-Self CBTI consists of: 1) Self-management via homework with a workbook, and 2) telephone-based nurse support. Participants will complete 6 weekly readings. The 6 weekly telephone contacts will be 20 minutes through a study nurse. Patients randomized to Health Education Control (HEC) will receive a health education workbook on 6 health topics and 6 weekly phone calls from a study nurse. All participants will continue to receive usual medical care while participating in study. Following completion of the 6 month study, Health Education group participants interested in additional help for their sleep will be referred to the Durham VA Behavioral Sleep Medicine Clinic.
- Detailed Description
Insomnia is one of the most common complaints among service-members and Veterans of recent military conflicts. Insomnia diagnoses increased 19-fold among military service members from 2000 to 2009. Insomnia has been shown to play a causal role in depression, anxiety, suicidality, disability due to a mental health disorder, hypertension, obesity, metabolic syndrome, diabetes, and all-cause mortality, thus serving as an additional risk factor for some of the most common medical conditions seen in patients utilizing the VA healthcare system. Cognitive-Behavioral Therapy for Insomnia (CBTI) produces both short-term and sustained resolution of insomnia with fewer adverse side effects than pharmacotherapy. But access to behavioral sleep medicine expertise within the VA is very limited.
Self-management and telehealth are viable options for achieving these goals.The proposed study is a randomized controlled trial comparing Tele-Self CBTI to Health Education Control for improved insomnia severity among treatment-seeking Veterans with Insomnia. In this 2-arm trial, 200 participants will be randomized in a 1:1 ratio to Tele-Self CBTI or a Health Education Control condition. Eligible participants are Veterans who are: a) prescribed sleep medications; b) diagnosed with insomnia; or c) referred for clinic-based CBTI (but not yet treated) will be identified using electronic health records (EHR) and telephone interviews.
Outcomes of subjective (sleep diary) and objective (actigraphy) measures of sleep onset latency (SOL), wakefulness after sleep onset (WASO), and sleep efficiency (SE) will be assessed at 3 time points: baseline, 8 weeks, and 6 months after baseline. Participants in both arms will continue to receive usual medical care. Each assessment period involves: a) 2 weeks of home-based sleep assessment (diary and actigraphy), and b) completion of telephone-based questionnaires. Following completion of a home-based sleep assessment period, a study staff member will conduct study questionnaires over the phone. Study participants will be asked to return actigraphy devices at the end of each assessment period.
Tele-Self CBTI is comprised of two treatment components: 1) Self-management via a workbook entitled, "Improve your Sleep: A Self-Guided Approach for Veterans with Insomnia" and 2) telephone-based nurse support. Participants will complete 6 weekly reading modules from the workbook with the following typical CBTI treatment components: Sleep Restriction; Stimulus Control; Cognitive Therapy; Relaxation; and Sleep Hygiene Education. The investigators will deliver Tele-Self CBTI across 6 weekly telephone contacts of 20 minutes or less through a study nurse. Patients randomized to Health Education Control (HEC) will receive 6 weekly phone calls from a study nurse. Consistent with phone contacts in the intervention arm, HEC phone contacts will last no more than 20 minutes and will match as closely as possible call duration with Tele-Self CBTI participants. Sleep-focused content will be prohibited during HEC calls.
In addition, a qualitative component of the study involves interviewing up to 20 nurses and 5 administrators to assess feasibility of study implementation.

- Primary Outcome Measures
Name Time Method Insomnia Severity Baseline to 8 weeks Insomnia Severity Index (ISI): The ISI is recommended as the standard for self-reported insomnia symptoms, and will be used as the primary outcome measure. The ISI is a 7-item questionnaire providing a global measure of perceived insomnia severity. Each item is rated on a 5-point Likert scale and the total score ranges from 0 (no reported symptoms) to 28 (highest insomnia severity symptoms). The following guidelines are recommended for interpreting the total score: 0-7 (no clinical insomnia), 8-14 (sub threshold insomnia), 15-21 (insomnia of moderate severity), and 22-28 (severe insomnia). In clinical samples, a cut off score of 11 was shown to have the greatest sensitivity and specificity for correctly identifying study participants meeting criteria for insomnia diagnosis.
- Secondary Outcome Measures
Name Time Method Subjective Sleep Onset Latency (SOL) Baseline to 8 week Sleep Diary sleep onset latency, using the Consensus Sleep Diary (CSD), which is the amount of time asleep in bed divided by the amount of time in bed, averaged across days. The investigators will use a call-in interactive Voice Response (IVR) approach to collect sleep diary data during each of the three 2-week assessment periods. Diary data will then be averaged across each 2-week assessment period.
Subjective Wake After Sleep Onset (WASO) Baseline to 8 week Sleep Diary WASO, using the Consensus Sleep Diary (CSD). The investigators will use a call-in interactive Voice Response (IVR) approach to collect sleep diary data during each of the three 2-week assessment periods. Diary data will then be averaged across each 2-week assessment period to determine SOL, WASO and SE.
Subjective Sleep Efficiency (SE) Baseline to 8 week Sleep Diary sleep efficiency, calculated from the Consensus Sleep Diary (CSD), which is the percent of the time asleep out of amount of time spent in bed. The investigators will use a call-in interactive Voice Response (IVR) approach to collect sleep diary data during each of the three 2-week assessment periods. Diary data are averaged across each 2-week assessment period.
Objective Wake After Sleep Onset Baseline to 8 week Objective WASO using Wrist Actigraphy: The investigators will use Actiwatch (Respironics, Inc.) wristwatch style actigraphs for collecting objective sleep data. Actiwatches contain a calibrated accelerometer that samples, digitizes, and stores movement activity. When interfaced with a computer, a scoring algorithm provides estimates of various sleep parameters. WASO is the total number of epochs between the start time and the end time of the given sleep interval scored as wake by Actiware software multiplied by the epoch length in minutes. The investigators will average data across each two-week assessment period. Not all participants completed actigraphy procedures
Objective Total Sleep Time (TST) Baseline to 8 week Objective total sleep time using Wrist Actigraphy: The investigators will use Actiwatch (Respironics, Inc.) wristwatch style actigraphs for collecting objective sleep data. Actiwatches contain a calibrated accelerometer that samples, digitizes, and stores movement activity. When interfaced with a computer, a scoring algorithm provides estimates of various sleep parameters. The investigators will average data across each two-week assessment period to determine actigraphy-based WASO, Total Sleep Time (TST) and SE. Not all participants completed actigraphy procedures
Objective Sleep Efficiency (SE) Baseline to 8 week Objective SE using Wrist Actigraphy. The investigators will use Actiwatch (Respironics, Inc.) wristwatch style actigraphs for collecting objective sleep data. Actiwatches contain a calibrated accelerometer that samples, digitizes, and stores movement activity. When interfaced with a computer, a scoring algorithm provides estimates of various sleep parameters. SE is the percentage of time spent in bed sleeping, scored total sleep time divided by (interval duration minus total invalid time (sleep/wake)) of the given rest interval multiplied by 100.The investigators will average data across each two-week assessment period.
