|---|---|---|---|
| Primary | Change in Daytime Insomnia Symptoms Scale (DISS) | Baseline (start of study) and end of study (before day 16). | This measure assesses daytime symptoms and functional impairments in five domains: alert cognition, fatigue, sleepiness, negative mood, and positive mood. Participants will complete this survey four times per day on their smart phone for approximately 16 days. The possible score range is 0-100, with higher scores indicating greater levels of a given construct. |
| Primary | Change in Insomnia Severity as Assessed by Insomnia Severity Index | Baseline (start of study) and end of study (before day 16). | The Insomnia Severity Index is a brief self-report instrument that measures subjective symptoms and consequences of insomnia as well as the degree of distress caused by those difficulties. Total scores range from 0 to 28, with higher scores indicating greater insomnia severity. |
| Secondary | Change in Sleepiness as Assessed by Epworth Sleepiness Scale | Baseline (start of study) and end of study (before day 16). | The Epworth Sleepiness Scale is a brief self-report instrument that measures daytime sleepiness. Total scores range from 0 to 24, with higher scores indicating greater severity of sleepiness. |
| Secondary | Change in Depression as Assessed by Patient Health Questionnaire-9 | Baseline (start of study) and end of study (before day 16). | The Patient Health Questionnaire-9 is a brief self-report instrument that measures depressive symptoms. Total scores range from 0 to 27, with higher scores indicating greater levels of depressive symptoms. |
| Secondary | Change in Anxiety as Assessed by Generalized Anxiety Disorder-7 | Baseline (start of study) and end of study (before day 16). | The Generalized Anxiety Disorder-7 is a brief self-report instrument that measures anxiety symptoms. Total scores range from 0 to 21, with higher scores indicating greater levels of depressive symptoms. |
| Secondary | Change in Cognitive Performance Assessed by the PVT (Psychomotor Vigilance Test): Lapses | Baseline (start of study) and end of study (before day 16). | PVT is a computer-based, chronometric test to measure reactions to specified small changes in a changing environment. Response time is scored in seconds. Response accuracy is scored numerically, with lower numbers indicating better response accuracy. |
| Secondary | Change in Cognitive Performance Assessed by the PVT (Psychomotor Vigilance Test): Median Reaction Time | Baseline (start of study) and end of study (before day 16). | PVT is a computer-based, chronometric test to measure reactions to specified small changes in a changing environment. Response time is scored in seconds. Response accuracy is scored numerically, with lower numbers indicating better response accuracy. |
| Secondary | Change in Cognitive Performance Assessed by the Stroop Test: Accuracy | Baseline (start of study) and end of study (before day 16). | Stroop test is a computer-based test of colors and words to measure cognitive interference. Response time is scored in seconds. Response accuracy is scored numerically, with lower numbers indicating better response accuracy. |
| Secondary | Change in Cognitive Performance Assessed by the Stroop Test: Response Time in Milliseconds | Baseline (start of study) and end of study (before day 16). | Stroop test is a computer-based test of colors and words to measure cognitive interference. Response time is scored in milliseconds. Response accuracy is scored numerically, with lower numbers indicating better response accuracy. |
| Secondary | Change in Cognitive Performance Assessed by the Task-switching: Response Time in Milliseconds | Baseline (start of study) and end of study (before day 16). | Task-switching is a computer-based, chronometric test to measure response time and response accuracy. Response time is scored in milliseconds. Response accuracy is scored numerically, with lower numbers indicating better response accuracy. |
| Secondary | Change in Cognitive Performance Assessed by the Task-switching | Baseline (start of study) and end of study (before day 16). | Task-switching is a computer-based, chronometric test to measure response time and response accuracy. Response time is scored in seconds. Response accuracy is scored numerically, with lower numbers indicating better response accuracy. |
