Technology Acceptance and Usability of the BrainFx SCREEN in Canadian Military Members and Veterans With Posttraumatic Stress Disorder and Mild Traumatic Brain Injury: Mixed Methods UTAUT Study.
Chelsea Jones, Antonio Miguel-Cruz, Suzette Brémault-Phillips
PMID 33983125WHAT IT FOUND
Veterans with PTSD accepted the BrainFx cognitive screen, citing support from staff as the main driver.
However, some found it distressing or misunderstood its purpose. This is a usability pilot, not evidence the tool improves care.
Key findings
01Facilitating conditions were the strongest predictor of intention to use the screen, and participants reported higher support after using it.
02Effort expectancy decreased after use, driven by complaints about touch screen delay and unclear task instructions.
03One participant reported being disturbed by the assessment images, despite them being generic and positive.

What it does not show
The study was underpowered due to a COVID-19 shutdown, with only 21 participants analyzed instead of the required 24. The sample was 95% male, preventing the use of gender as a moderator variable. The BrainFx SCREEN is a new tool that has not yet been validated for reliability or sensitivity. Participants had treatment-resistant PTSD, so results may not generalize to those with different severity or treatment histories. Some participants did not fully understand the purpose of the assessment, which may have skewed their responses about performance expectancy.
Declared interests
The authors declared no conflicts of interest.
The easy way to misread this
Do not interpret the positive acceptance ratings as evidence that the BrainFx SCREEN is a valid or effective clinical tool. This was a small pilot study focused on user experience, not on the accuracy or clinical utility of the cognitive scores themselves.
