Description of Cognitive Task in the Brief Test of Adult Cognition by Telephone (BTACT)

Cognitive outcome	Task name	Description	Score
Executive functioning	Backward digit span	Participants are given two sets of a series of numbers that increase in length, starting with series of two digits and continuing to sequences of eight digits. They are asked to repeat the digit series in reverse order to how they are presented.	The highest number of digits repeated correctly
	Category verbal fluency	Participants are asked to produce as many words in a given category as possible in 60 s.	The number of unique items generated
	Number series	Participants hear a series of numbers that follow a particular pattern and are asked to name the next number in the sequence.	The number of correct items
	30 s and counting task	Participants are asked to count backwards from 100 in 30 s.	Last number reached
	Stop and Go Switch Task	Participants are instructed to respond STOP when they hear the word RED, and Go when they hear the word GREEN in the normal condition. In switch condition, they are asked to answer STOP to GREEN and GO to RED.	Average of the mixed-task nonswitch trials median reaction time (RT) and mixed-task switch trials median RT, then multiplied by −1
Episodic memory	Immediate word list recall	After listening to a list of words, participants are asked to recall the words in 90 s.	The number of correctly recalled words for each condition
	Delayed word list recall	Participants are asked to recall the words at the end of BTACT.	The number of correctly recalled words for each condition
