Outcome Measures
Primary Outcomes (1)
To investigate the effect of the administration of a 50mg and 100mg per day oral CBD product versus placebo over 8 weeks on insomnia severity index scores
Insomnia Severity Index (ISI): A 7-item tool measuring the nature, severity, and impact of insomnia over the past 2 weeks. Each item uses a 5-point Likert scale to capture a rating (0 = no problem; 4 = very severe problem) which add up to: no insomnia (0 - 7); sub-threshold insomnia (8 - 14); moderate insomnia (15 - 21); and severe insomnia (22 - 28).
Baseline (week 0), week 4, week 8
Secondary Outcomes (3)
To determine the effect of 8 weeks of 50mg or 100mg of CBD compared to placebo on wake after sleep onset (WASO) as assessed by actigraphy.
Baseline (week 0), week 8
To determine the effect of 8 weeks of 50mg or 100mg of CBD compared to placebo on Anxiety as assessed by the DASS-21 questionnaire.
Baseline (week 0), Week 4, week 8
To determine the effect of 8 weeks of 50mg or 100mg of CBD compared to placebo on Stress as assessed by the DASS-21 questionnaire.
Baseline (week 0), Week 4, week 8
Other Outcomes (9)
To determine the effect of 8 weeks of 50mg or 100mg of CBD compared to placebo on Sleep onset latency (SOL) measured by actigraphy.
Baseline (week 0), week 8
To determine the effect of 8 weeks of 50mg or 100mg of CBD compared to placebo on subjective sleep as assessed by sleep diaries
Baseline (week 0), week 4, week 8
To determine the effect of 8 weeks of 50mg or 100mg of CBD compared to placebo on self-perception of improvement in sleep as assessed by a self-report questionnaire.
Baseline (week 0), week 4, week 8
