Assessment of anosognosia in persons with frontal lobe damage: Clinical utility of the Mayo-Portland adaptability inventory (MPAI)

Abstract

Objectives: To determine if the Mayo-Portland Adaptability Inventory (MPAI) demonstrates clinical utility in differentiating between persons with severe TBI and frontal lobe damage/anosognosia and persons with mild TBI and no frontal lobe damage.

Participants: Forty-three persons with TBI and documented frontal lobe damage (mean age = 34; mean time since injury = 5.2 years) and 69 persons with mild TBI and no frontal lobe damage (mean age = 34.3; mean time since injury = 4.8 years).

Measure: MPAI.

Results: Total inventory and select sub-category difference scores were significantly greater in the frontal lobe group than in the non-frontal lobe group. However, as expected, there was no significant difference between the two groups on the mobility sub-category difference scores.

Conclusions: The MPAI appears to be potentially clinically useful in assessing for frontal lobe damage and associated anosognosia in patients with TBI.
