Individuals with acquired brain injury (ABI) may experience challenges in their everyday occupational performance due to cognitive impairments. Cognitive tabletop and occupation-based assessments are used to evaluate cognition in individuals with ABI. There is a need for cognitive occupation-based assessments as they possess ecological validity: a reflection of an individual’s occupational performance in daily life. This study aimed to validate the Medication Box Task assessment in its use as a cognitive occupation-based assessment. The results of the Medication Box Task assessment were compared against the results of a battery of five gold standard tabletop assessments. Pearson correlations showed significant correlations between type II errors of the Tower of London and the extra and missing pills of the Medication Box Task assessment. No other significant correlations were found between scores of the Medication Box Task assessment and the battery of cognitive tabletop assessments. More importantly, it was discovered that six out of seven participants, who indicated that they managed their own medication, made errors on the Medication Box Task assessment. Based on the results, no conclusion can be made about the Medication Box Task assessment as a valid cognitive occupation-based assessment.
