3.1.0.1 Definition
Brief Test of Adult Cognition by Telephone (BTACT)
The BTACT is a brief (15-20 minute) and reliable telephone-administered test that includes six subtests assessing important areas of cognition. The subtests were selected for inclusion in the BTACT based on their ability to assess a wide range of cognitive abilities (see below) and for their sensitivity to normal age-related changes. Other important features of the subtests include well-established psychometric properties, ease of administration via telephone by lay interviewers, and brief administration time. Two psychometrically equivalent alternate forms are available, and the BTACT is available in English and Spanish. Previous research has demonstrated that in-person and telephone administration of BTACT subtests yield equivalent results (Lachman et al., 2011). The subtests in the BTACT include: Rey Auditory Verbal Learning Test, Digits Backward, Number Series, Animal Fluency, Backward Counting.
Descriptions of subtests included in the Brief Test of Adult Cognition by Telephone BTACT:
EPISODIC VERBAL MEMORY (Word List Recall) - Immediate Recall of 15-item word list (RAVLT; 1 trial only) SCORE = Total correct in 60 sec (Optional: repetitions, intrusions, Recall efficiency (total time/#words)) and Delayed Recall of word list (at end of assessment) Score = Total correct (Optional: repetitions, intrusions, Forgetting (Immediate-delayed recall)).
WORKING MEMORY (Digits Backward [WAIS-III]) Score = Longest accurately recalled string.
EXECUTIVE (Category Animal Fluency) Score = Number correct in 60 seconds, (Optional: repetitions, intrusions).
REASONING (Number Series ) Score = Number correct (5 trials of increasing difficulty).
REACTION TIME (Backward Counting) Score = Last number reached minus number of errors (reversals, skips, incorrect numbers).

3.1.0.4 Details
See BTACT SOP link below for full administration guidelines.
Form 1
If BTACT window closes prior to patient consenting to the TBIMS, clinical judgement should be used to code whether or not BTACT could have been completed at that time (e.g., consult with treating neuropsychologist or other rehab team members). If determined patient would not have been able to complete the BTACT due to cognitive impairment, code as “Not Attempted due to cognitive impairment.” Do not attempt to abstract information from the medical record to make this determination.
If a proxy consents to the TBIMS for the participant, all attempts should still be made to complete the BTACT with the participant, even if the participant is not out of PTA.

3.1.0.7 Characteristics
Researchers should evaluate the appropriate “window” for each specific study, and exclude BTACT data collected outside of their preferred window.
