PMID 34371016WHAT IT FOUND
The Behavior Rating Inventory of Executive Function-Adult Version does not support its nine specific subscale scores in people with TBI.
Only the two broad index scores and two newly identified traits (Behavioral Control and Emotional Control) accurately reflect the test items.
Key findings
01The test's nine subscales do not measure nine distinct traits; instead, the data supports only two broad indexes and two underlying traits.
02Within the Behavioral Regulation Index, items grouped into two traits: Behavioral Control and Emotional Control, rather than the manual's four scales.
03Within the Metacognition Index, all items loaded onto a single factor, indicating it measures one construct rather than five separate scales.

What it does not show
The study used a convenience sample that was mostly male and unemployed, which may limit generalizability to other populations. More than 50% of the sample were veterans with mild TBI, so findings may not apply equally to civilians with mild TBI. The study did not include informant reports, which may have a different factor structure than self-reports. New normative standards for the proposed traits have not yet been established.
The easy way to misread this
Do not interpret the nine subscale scores as measuring nine distinct areas of executive function. The study found that these subscales do not have a valid factor structure in people with TBI, so relying on them may lead to incorrect assumptions about a patient's specific cognitive deficits.
