Outcome Measures
Primary Outcomes (1)
Change in Insomnia Symptom Severity
Change in Insomnia Severity Index score from baseline to follow-up. The Insomnia Severity Index is a 7-item self-report questionnaire that measures severity of insomnia symptoms during the last two weeks. Each item is scored 0 (no problem) to 4 (very severe problem) and total between 0-28, with higher scores indicating more severe insomnia symptoms. Change is estimated mean change from mixed-effects linear regression model. Fixed effects: Baseline ISI, Treatment Arm, Visit and Treatment Arm\*Visit interaction. Random effects: intercept for Subject, nested within Site.
