Comprehension of Miranda warnings in adults with chronic, moderate-severe traumatic brain injury.

PMID 39029420WHAT IT FOUND
Adults with chronic moderate-to-severe TBI understood Miranda warnings less accurately than non-injured peers.
SLPs should evaluate legal comprehension for individuals with TBI interacting with the justice system, as complex language and stress may further impair their ability to exercise rights.
Key findings
01Participants with TBI performed significantly less accurately on the Miranda Rights Comprehension Instruments than non-injured peers.
02The study environment was quiet and low-stress, unlike real-world arrests, suggesting the findings may underrepresent the impact of TBI on legal comprehension.
03Speech-language pathologists are uniquely positioned to support individuals with TBI in legal settings and should evaluate language comprehension in these contexts.

What it does not show
The study used a small sample size (n=50). The MRCI was administered via Zoom due to the pandemic, which deviates from the intended in-person protocol. The testing environment was quiet and low-stress, unlike the high-stress context of an actual arrest. The sample consisted only of adults injured in adulthood, excluding those with childhood TBI. Most participants did not have a history of incarceration, limiting generalizability to those familiar with the legal system.
Declared interests
The authors declared no conflicts of interest. The study was not funded by a commercial entity, and the authors state they used LanguageTool for grammar assistance.
The easy way to misread this
Do not assume these results reflect performance in a real arrest scenario. The study was conducted in a quiet, low-stress environment with unlimited time, whereas actual legal interactions involve high stress, complex language, and time pressure, which likely worsen comprehension for individuals with TBI.
