Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of participants with altered cognitive function at 6hrs post-dose | 6hrs post-dose | This outcome measure is assessed by the number of participants whose scores on a range of cognitive tasks (word and picture recall and recognition, serial 3s and 7s subtractions, rapid visual information processing (RVIP), N-Back (3-Back version), Stroop and numeric working memory) differed from baseline to the 6hr post-dose scores. |
| Number of participants with altered cognitive function at 40mins post-dose | 40mins Post-dose | This outcome measure is assessed by the number of participants whose scores on a range of cognitive tasks (word and picture recall and recognition, serial 3s and 7s subtractions, rapid visual information processing (RVIP), N-Back (3-Back version), Stroop and numeric working memory) differed from the baseline to 40min post-dose scores. |
| Number of participants with altered cognitive function at 2.5hrs post-dose | 2.5hrs post-dose | This outcome measure is assessed by the number of participants whose scores on a range of cognitive tasks (word and picture recall and recognition, serial 3s and 7s subtractions, rapid visual information processing (RVIP), N-Back (3-Back version), Stroop and numeric working memory) differed from baseline to the 2.5hr post-dose scores. |
| Number of participants with altered cognitive function at 4hrs post-dose | 4hrs post-dose | This outcome measure is assessed by the number of participants whose scores on a range of cognitive tasks (word and picture recall and recognition, serial 3s and 7s subtractions, rapid visual information processing (RVIP), N-Back (3-Back version), Stroop and numeric working memory) differed from baseline to the 4hr post-dose scores. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of participants with altered mood at 40mins post-dose. | 40mins post-dose | This outcome was assessed by the number of participants whose baseline mood scores (as assessed by the Bond-Lader mood scale which categorises 'alert', 'content' and 'calm') differed from the 40mins post-dose scores. |
| Number of participants with altered mood at 2.5hrs post-dose | 2.5hrs post-dose | This outcome was assessed by the number of participants whose baseline mood scores (as assessed by the Bond-Lader mood scale which categorises 'alert', 'content' and 'calm') differed from the 2.5hrs post-dose scores. |
| Number of participants with altered mood at 4hrs post-dose | 4hrs pos-dose | This outcome was assessed by the number of participants whose baseline mood scores (as assessed by the Bond-Lader mood scale which categorises 'alert', 'content' and 'calm') differed from the 4hrs post-dose scores. |
| Number of participants with altered mood at 6hrs post-dose | 6hrs post-dose | This outcome was assessed by the number of participants whose baseline mood scores (as assessed by the Bond-Lader mood scale which categorises 'alert', 'content' and 'calm') differed from the 6hrs post-dose scores. |
