Validation

BOCA has been validated in multiple studies. In one study, participants with cognitive disorders scored significantly lower in both the BOCA and Montreal Cognitive Assessment (MoCA) Test for Dementia compared to normal controls. In another study, participants with cognitive disorders scored significantly lower in both the BOCA and Telephone Interview for Cognitive Status (TICS) compared to normal controls.

Correlational analyses revealed strong correlation between BOCA and Montreal Cognitive Assessment (r = 0.85, p < 0.01) and strong correlation with the Telephone Interview for Cognitive Status (r = 0.80, p < 0.01).

BOCA showed strong test-retest reliability of the total BOCA score one week after participants’ initial administration (r= 0.89, p <0.001).
