Sleep disturbance is a common condition following traumatic brain injury (TBI) and impairs recovery and quality of life. While efficacious interventions exist many are not accessible to all patients due to a variety of factors (e.g., rurality, access to providers). Further, many of the available treatments have not been validated for individuals with moderate/severe TBI. The proposed study will evaluate a guided computerized version of cognitive behavioral therapy for insomnia (cCBT-I) against enhanced treatment as usual (ETU) in individuals with moderate/severe TBI.

Individuals with a history of moderate to severe TBI experience multi-faceted sleep problems, including greater daytime sleepiness, lesser total sleep time, and difficulties with initiating, maintaining, and self-monitoring sleep. Such sleep complaints may reflect underlying sleep conditions such as insomnia, the prevalence of which is significantly greater among individuals with TBI (29%) compared to members of the general population (10%). As such, treatment of insomnia among individuals with moderate to severe TBI is expected to produce wide-ranging benefits in regards to short- and long-term rehabilitation. Among members of the general population, cognitive behavioral therapy for insomnia (CBT-I) is considered the gold standard for treating insomnia. CBT-I focuses on improving sleep quality via cognitive therapy, behavioral techniques, and psychoeducation. However, access to in-person treatment has been limited by cost, insufficient numbers of adequately trained healthcare providers, and patient perceptions regarding the efficacy of the intervention, as well as additional barriers that may be particularly pertinent for those living with moderate to severe TBI (e.g., limited transportation). Optimally, an intervention for those with TBI and insomnia would show efficacy at reversing sleep inefficiency, and be able to be used with minimal stigma. In addition, the intervention should be highly accessible, low cost, self-sustaining (e.g., portable), and with minimal side effects.

Computerized versions of CBT-I assist in reducing barriers to access and have been found to be acceptable and efficacious in a variety of populations, including those with mild TBI. To date, research among those with moderate to severe TBI has been limited. This study will address this gap by examining the efficacy of a guided computerized CBT-I (CCBT-I) intervention for those with moderate to severe TBI and insomnia. That is, we will implement a free, computerized version of CBT-I, provided in conjunction with guidance (e.g., prompts or reminders to complete modules, help or support using the program and/or completing the modules) by a licensed mental health professional (Study Clinician). As participants will be recruited from the community at-large across the State of Colorado, it is believed that findings will be highly generalizable.

Moreover, both geography (where an individual resides) and challenges with transportation create barriers to treatment access and research participation among those living with moderate to severe TBI. As such, all study procedures will be completed remotely. During the Coronavirus Disease 2019 (COVID-19) pandemic, members of this study team explored and implemented multiple methods to facilitate remote research participation (e.g., video conferencing, data collection via Research Electronic Data Capture [REDCap], mailing study data collection devices). Employing such methods will allow individuals in both rural and urban areas across Colorado to participate.
