The purpose of this study is to investigate whether an empirically validated treatment for insomnia (CBT-I) administered early in the course of sleep disturbance can prevent insomnia disorder or lessen negative mental health outcomes in the wake of the COVID-19 crisis in adults.
The COVID-19 Pandemic and the resulting mass home confinement enacted to mitigate disease spread has created an environment of stress and drastic disruption to daily life. Increases in stress, social isolation, loss of daily routine, decreased physical activity, and excess screen time that are likely to arise as a function of the pandemic and mitigation efforts are risk factors for developing insomnia. Left unchecked, this acute insomnia can become chronic, resulting in increased risk of negative mental health outcomes such as depression, anxiety, and suicidality. The current proposal aims to test whether a telehealth intervention for insomnia can be used to not only prevent the progression of acute to chronic insomnia, but also prevent the worsening of neuropsychiatric symptoms, suicidality, and quality of life in those most vulnerable to negative mental health outcomes. These aims will be achieved through a randomized 2-arm controlled trial design. 50 eligible adults experiencing sleep disturbances and who also have a history of depression and are in the at-risk group for COVID-19 will be randomized to receive either a sleep intervention (Cognitive Behavioral Therapy for Insomnia, CBT-I; n=25) or a 7-month waitlist (n=25). CBT-I improves sleep patterns through a combination of sleep restriction, stimulus control, mindfulness training, cognitive therapy targeting dysfunctional beliefs about sleep, and sleep hygiene education. Neuropsychiatric symptoms, Quality of Life, suicidality, and sleep disruption will be assessed at baseline (Week 0) and at the end of the sleep intervention (or Week 7) through online surveys and clinical interviews. Neuropsychiatric symptoms (anxiety and depression) and sleep disturbance (Insomnia Severity Index, and sleep diaries) will be assayed at baseline and each week throughout treatment/waitlist to assess week-to-week changes following an increasing number of CBT-I sessions. Neuropsychiatric symptoms, quality of life, suicidality, and sleep will be assessed again at 3-months, 7-months, and 13-months after baseline.

Participants will meet with a psychologist through telehealth once a week for four weeks to complete a brief CBT-I intervention. Cognitive Behavioral Therapy for Insomnia consists of a cognitive therapy and a behavioral therapy. The cognitive therapy is designed to identify incorrect ideas about sleep, challenge their validity, and replace them with correct information. This therapy tries to reduce worry, anxiety, and fear that one won't sleep by providing accurate information about sleep. The behavioral therapy increases sleep quality by limiting excessive time spent in bed to increase homeostatic sleep drive and sleep consolidation.

Change in Insomnia Clinical Diagnosis Over Time
Whether the participant has an insomnia clinical diagnosis will be measured by the DUKE. The DUKE is a structured interview which screens for sleep disorders in accordance with criteria of both the DSM-IV and the international classification of sleep disorders (ICSD-2). The DUKE is composed of 4 modules that assess sleep disorder symptoms associated with complaints of insomnia, sleep disorders associated with complaints of hypersomnia, circadian rhythm sleep disorders, and sleep disorders associated with parasomnias.

Change in Patient Health Questionnaire-9 (PHQ-9) Scale Score as a Measure of Depression Symptoms Over Time
The PHQ-9 is a self-administered 9-item 0 to 3 scale (0 = not at all, 3 = nearly every day) questionnaire that assess each of the 9 DSM-IV depression criteria. The total score ranges from 1 - 27 which measures the severity of the reported depression with consideration for both Major Depressive Disorder and other depressive disorders based on the number of items that were rated a 2 to 3.

Change in Generalized Anxiety Disorder-7 (GAD-7) Scale Score Over Time
The GAD-7 is a widely used diagnostic self- report scale that screens, diagnoses, and assess severity of anxiety disorder. The GAD-7 is a 7-item 0 to 3 (0 = Not at all, 3 = Nearly every day) scale that measures the degree of severity of anxiety over the last 2 weeks with a total score ranging from 0 to 21, with a higher score indicating a more severe anxiety.

Change in Insomnia Severity Index (ISI) Scale Score Over Time
Subjective ratings of sleep disturbance and insomnia severity will be assessed with the Insomnia Severity Index. The Insomnia Severity Index (ISI) is a 7-item self-report measure of insomnia type, severity, and impact on functioning. The items consist of severity of sleep onset, sleep maintenance, early morning awakenings, sleep dissatisfaction, interference with daytime functioning, noticeability of sleep problems by others, and distress caused by sleep difficulties. Items are scored from 0 to 4 (0 = no problem, 4 = very severe problem). Score ranges of insomnia are: 0-7 absent, 8-14 sub-threshold, 15-21 moderate, and 22-28 severe. The ISI has good validity and reliability.

Change in Quality of Life (SF-36) Scale Score Over Time
The SF-36 is a 36-item self-administered survey to assess comprehensive quality-of-life measures. It consists of eight sections: vitality, physical functioning, bodily pain, general health perceptions, physical role functioning, emotional role functioning, and mental health. This survey is widely used and has been proven to be a reliable indicator of quality-of-life measures. The global score range is 0-100, with higher scores indicating better health conditions.

Suicidality ideation and behaviors will be measured by the S-STS. The S-STS is a 16-item 0 to 4 scale (0 = no problem, 4 = very severe problem) that assesses the risk of suicidality. For this outcome measure, 15 items (excluding #13) are summed for an overall score range of 0 to 45 (higher scores indicate more severe problems).

The BDI-II is a 21-item self-report scale with high validity and reliability that assesses the severity of depression symptoms. The depression items consist of: sadness, pessimism, past failure, loss of pleasure, guilty feelings, punishment feelings, self-dislike, self-criticalness, suicidal thoughts or wishes, crying, agitation, loss of interest, indecisiveness, worthlessness, loss of energy, changes in sleeping pattern, irritability, changes in appetite, concentration difficulty, tiredness or fatigue, and loss of interest in sex. Items are scored from 0 to 3, and higher scores indicate greater levels of severity.
