nsomnia is a frequent complaint reported by patients with TBI, and exacerbates their ability to return to productive activity, which subsequently elevate related healthcare costs and burden. Existing literatures found that effects of CBTi, first-line therapy for insomnia, on post-traumatic insomnia is still debated, indicating that developing an alternative nonpharmacological therapy for alleviating insomnia following TBI is required. Besides, digital health is one of strategies to achieve precision health. Thus far, knowledge regarding whether mobile-delivered BBTi has non-inferiority effects as BBTi in treating insomnia is still lacking. Therefore, a RCT with a large sample size to examine the immediate and lasting effects of BBTi and mobile-delivered BBTi on insomnia, mood disturbances, and cognitive dysfunctions in patients following TBI at the recovery stage compared with the control participants.
Background: Insomnia is highly prevalent in adults with traumatic brain injury (TBI), which in turn undermine their mood, cognitive functions, and quality of life. However, an effective non-pharmacological intervention for managing insomnia in this population is still lacking. Nurses, the first-line healthcare providers, should therefore seek an approach for managing post-TBI sleep. Brief behavioral treatment for insomnia (BBTi) is a new treatment direction for primary and comorbid insomnia; however, its treatment model has not been applied in people with neurological deficits such as TBI.
Purposes: To establish the BBTi treatment model among insomniacs in Taiwan, and to examine the immediate and lasting effects of nurse-guided BBTi and mobile-delivered BBTi on sleep, mood, and cognitive functions in adults with TBI. We hypothesize that people with TBI undergoing nurse-guided BBTi and mobile-delivered BBTi will experience greater alleviations in insomnia, mood disturbances, and cognitive dysfunctions in comparison with participants in the sleep hygiene control group.
Methods: This 3-year, assessor-blinded randomized controlled trial will employ a three-arm parallel-group design. A total of 228 TBI survivors with insomnia complaints will be randomly allocated to the nurse-guided BBTi, mobile-delivered BBTi, or sleep hygiene control group in a 1:1:1 ratio. For the nurse-guided BBTi group, all participants will experience 4-week-long BBTi via 2 in person and 2 telephone sessions. For the mobile-delivered BBTi, participants will use the apps in conjunction with the standard BBTi procedures provided by the functions of apps: "Sleep Aids" and "Relaxation therapy". For the sleep hygiene control group, they will receive usual care and sleep hygiene education. Measurement outcomes are sleep parameters measured by the Chinese version of Insomnia Severity Index, Chinese version of Epworth sleepiness scale, Chinese version of Pittsburgh sleep quality index, and 7-day actigraphy with a sleep diary. Secondary outcomes consist of mood and cognitive functions assessed using The Depression, Anxiety and Stress Scale - 21 Items, Ruff 2 & 7 test, Rey Auditory Verbal Learning Test, and Symbol Digit Modalities Test.
Questionnaires and actigraphy will be assessed in pretreatment, posttreatment, and the 6th and 12th months after treatment. A generalized estimating equation will be used to test research hypotheses.

| Measure | Description | Time Frame |
|---|---|---|
| Changes in Insomnia Severity | The ISI consists of seven items, and each item can be rated from 0 to 4, resulting in total score ranging from 0 to 28, with higher scores indicating greater insomnia severity. A cutoff score of > 7 is used to diagnose subthreshold insomnia. | at baseline and the 5th week and the 12th week after intervention finished and the 24th week after intervention finished |
| Changes in Sleep quality | Sleep quality will be measured by Pittsburgh Sleep Quality Index (PSQI). PSQI has 18 questions to evaluate sleep condition. The score range from 0-21, if score>5 is associated with poor sleep. The higher score means poorer sleep quality. | at baseline and the 5th week and the 12th week after intervention finished and the 24th week after intervention finished |
| Changes in Daytime Sleepiness | Daytime Sleepiness will be measured by Epworth Sleepiness Scale (ESS). ESS has 8 questions to evaluate the condition of dozing off or falling asleep. The score range from 0-24, if score>10 is associated with daytime sleepiness. | at baseline and the 5th week and the 12th week after intervention finished and the 24th week after intervention finished |
| Changes in Sleep parameters from sleep logs: sleep onset latency(SOL) | Sleep onset latency(SOL) is the time of duration from lying on bed to fall asleep. SOL shorter than 30 minutes is one of criteria of good sleep condition. | at baseline and the 5th week and the 12th week after intervention finished and the 24th week after intervention finished |
| Changes in Sleep parameters from sleep logs: after sleep onset(WASO) | Wake after sleep onset(WASO) is the total time of wakefulness after sleep onset. WASO less than 30 minutes is one of criteria of good sleep condition. |
| Measure | Description | Time Frame |
|---|---|---|
| Changes in Depression | Depression will be measured by Depression Anxiety Stress Scale-21 (DASS21). DASS21 has 21 questions to evaluate the state of depression, anxiety, and stress. 7 of the questions are used to measure the severity of depression. The total score should be multiplied by 2 range from 0-42, if score>9 is associated with depression. The higher score means more severe depression. | at baseline and the 5th week and the 12th week after intervention finished and the 24th week after intervention finished |

| Changes in Ruff 2 and 7 | The Ruff 2 & 7 test will be used to test sustained and selective aspects of visual attention. It consists of 20 trials (10 Automatic Detection trials and 10 Controlled Search trials), with three line per trial, administered consecutively in 15-s intervals, working from left to right. The Automatic Detection and Controlled Search scores will used to assess selective attention. Sustained attention is measured primarily by the Total Speed (number of correctly identified targets during the allotted 5-min duration), and Total Accuracy (number of targets identified during the 5-min duration divided by the number of possible targets) scores. | at baseline and the 5th week and the 12th week after intervention finished and the 24th week after intervention finished |
| Changes in Rey Auditory Verbal Learning Test (RAVLT) | The RAVLT is a measure of verbal memory in which a subject is read a list of 15 words and asked to recall them after the examiner finishes reading the list. The subjects are exposed to the second list once, after which they must recall as many words as they can from the first list. After a 30-minute delay, the subjects are again asked to recall the words from the first list; they subsequently participate in a recognition trial in which they determine whether the word heard was in the first list. | at baseline and the 5th week and the 12th week after intervention finished and the 24th week after intervention finished |
| Changes in Symbol digital modalities | The SDMT is a brief test of information processing speed that has become the most commonly used cognitive measure in patients with TBI. It consists of a sheet of paper with a sequence of nine symbols and nine corresponding numbers at the top. Responses can be written or oral, and for either response mode, the administration time is 5 min. A higher score indicates a more favorable performance. | at baseline and the 5th week and the 12th week after intervention finished and the 24th week after intervention finished |
