Objective: To evaluate the utility of a performance-based test (PBT), the 2 × 3 Multi-Level Action Test (2 × 3), as an assessment measure for individuals with mild to severe traumatic brain injury (TBI). 2 × 3 performance for individuals with TBI who report difficulties in everyday functioning was compared to healthy control participants. The associations between 2 × 3 performance, traditional neuropsychological measures (NPs), and self-reported deficits were examined. Method: This prospective observational study was conducted at a metropolitan medical center. Forty-four adults living in the community qualified. Participants completed self-report measures (demographic and health questionnaire; BISQ; BRIEF; BDI-II), the 2 × 3, and NPs (RBANS-B, WCST-SF, TMT-A & B, D-KEFS Tower, Color-Word, and Design Fluency) in a 2-hour session. The 2 × 3 requires completing three tasks twice (packing a lunchbox, wrapping a present, and making toast). Results: 2 × 3 data were available for 28 participants (15 TBI; 13 control). TBI participants exhibited a range for task accomplishment (46 to 100%) and overall score (4 to 18). Preliminary analyses showed significant group differences with TBI participants completing the tasks slower (t(25) = 2.34, p = .03) and making more action addition errors (t(26) = 2.42, p = .02). 2 × 3 performance and self-report were significantly related to executive function NPs. TBI participants with more self-reported organizational difficulties took longer to complete the 2 × 3 (r(13) = .74, p < .001). Conclusions: This study shows promise for the 2 × 3 to be used with individuals with TBI, particularly as a range of performance was exhibited, not suggesting ceiling and floor effects. Relationships between 2 × 3 performance and other measures are important for establishing construct validity. More research would be helpful to decipher additional information this PBT may provide about individuals’ deficits and functioning.
