Abstract
Objective
To assess the responsiveness of the Traumatic Brain Injury–Quality of Life (TBI-QOL)
measurement system.
Design
Participants completed the 20 TBI-QOL item banks and the Participation Assessment
with Recombined Tools–Objective (PART-O) Productivity Subscale at baseline and 6-month
follow-up assessments. Participants were categorized into 4 groups (increased productivity,
unchanged productivity, and decreased productivity) based on PART-O Productivity scores.
Paired sample t tests were used to compare TBI-QOL scores at baseline and 6 months, and standardized
response means and Cohen's d were computed to estimate effect sizes.
Setting
Three traumatic brain injury (TBI) Model Systems rehabilitation centers in the United
States.
Participants
Two hundred one community-dwelling adults with TBI.
Interventions
Not applicable.
Main Outcome Measures
20 TBI-QOL item banks.
Results
As expected, given that there was no intervention, group mean TBI-QOL subdomain scores
for the entire sample showed no change or small improvement over the 6-month study
period. At the follow-up assessment, 72 participants reported increased productivity,
71 reported decreased productivity, and 58 reported the same level of productivity
as they had 6 months prior. When compared with participants who reported unchanged
or decreased productivity, participants who reported increased productivity on the
PART-O subscale had clinically meaningful (d≥0.30) improvements on 7 TBI-QOL measures. The largest improvement was in the Independence
subdomain (mean change, 7.06; df=0.84), with differences also observed in the Mobility, Positive Affect and Well-Being,
Resilience, Grief/Loss, Ability to Participate, and Satisfaction with Participation
subdomains.
Conclusions
The 20 TBI-QOL item banks demonstrate responsiveness to change and measurement stability
in a community-dwelling sample. Researchers may use the TBI-QOL to detect changes
in HRQOL after a clinical intervention and clinicians may use it in their daily practices
to monitor patient recovery.
