Clinical Trial Summary

The primary aim of this randomised, double-blind, placebo-controlled, cross-over study is to assess the short-term cognitive effects of two beverages containing 100 and 300 mg coffeeberry extract (obtained from the fruit of the coffee plant (Coffea arabica) compared to a placebo beverage. The trial will utilise the COMPASS cognitive assessment system and cognitive demand battery (CDB) and mood visual analogue scales (VAS) with assessments taking place at baseline, 60- and 120-minutes post treatment, on four separate testing days separated by 7 days. A treatment containing 75 mg caffeine will be used as a positive control to document participants' responsiveness to an established psychostimulant.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mental fatigue Visual Analog Scale (VAS) score	0-100 mm subjective rating scale, not at all to extremely, within Computerised Mental Performance Assessment framework tasks (COMPASS)	Change from baseline to 120 min post-coffeeberry beverage (100 and 300 mg) consumption during a Cognitive Demand Battery (CDB), compared to placebo beverages. Less mental fatigue is better.
Primary	Mental alertness Visual Analog Scale (VAS) score	0-100 mm subjective rating scale, not at all to extremely, within Computerised Mental Performance Assessment framework tasks (COMPASS)	Change from baseline to 120 min post-coffeeberry beverage (100 and 300 mg) consumption during a Cognitive Demand Battery (CDB), compared to placebo beverages. More mental alertness is better.
Secondary	Mental fatigue Visual Analog Scale (VAS) score	0-100 mm subjective rating scale, not at all to extremely, within Computerised Mental Performance Assessment framework tasks (COMPASS). Less mental fatigue is better.	Change from baseline to 60 min post-coffeeberry beverage (100 and 300 mg) consumption, during a Cognitive Demand Battery (CDB), compared to placebo and caffeine beverages
Secondary	Mental Alertness Visual Analog Scale (VAS) score	0-100 mm subjective rating scale, not at all to extremely, from within Computerised Mental Performance Assessment framework tasks (COMPASS)	Change from baseline to 60 min post-coffeeberry beverage (100 and 300 mg) consumption, during a Cognitive Demand Battery (CDB), compared to placebo and caffeine beverages. More mental alertness is better.
Secondary	Motivation Visual Analog Scale (VAS) score	0-100 mm subjective rating scale from none to strongest feelings, within Computerised Mental Performance Assessment framework tasks (COMPASS)	Change from baseline to 60 and 120 min post-coffeeberry beverage (100 and 300 mg) consumption, during a Cognitive Demand Battery (CDB), compared to placebo and caffeine beverages. More motivation is better.
Secondary	Fatigue (Mental State Energy and Fatigue Scales, (EFS)) score	Subjective feelings of mental energy and mental fatigue. Intensity rating scale from none to strongest, yields composite score ranging from 0-300, included within Computerised Mental Performance Assessment framework tasks (COMPASS)	Change from baseline to 60 and 120 min post-coffeeberry beverage (100 and 300 mg) consumption, following CBD, compared to placebo and caffeine beverages. Less fatigue is better.
