OBJECTIVES: To identify areas of most restricted self-reported participation among Veterans with traumatic brain injury (TBI), explore associations among participation restriction and clinical characteristics, and examine differences in participation restrictions by sex.
DESIGN: Retrospective cross-sectional design.
SETTING: National VA Polytrauma System of Care outpatient settings.
PARTICIPANTS: Veterans with a confirmed TBI event (N = 6,065).
INTERVENTIONS: Not applicable.
MAIN OUTCOME MEASURE(S): Mayo-Portland Participation Index (M2PI), a five-point Likert-type scale with eight items. Total score was converted to standardized T-score for analysis.
RESULTS: The sample consisted of 5,679 male and 386 female veterans with one or more clinically confirmed TBI events (69% Caucasian; 74% with blast exposure). The M2PI items with greatest perceived restrictions were social contact, leisure, and initiation. There were no significant differences between males and females on M2PI standardized T-scores. Wilcoxon rank-sum analyses showed significant differences by sex on four items: leisure, residence, employment, and financial management (all P < 0.01). In multinomial logistic regression on each item controlling for demographics, injury characteristics, and comorbidities, female Veterans had significantly greater relative risk for part time work and unemployment on the employment item and significantly less risk for impairment on the residence and financial management item.
CONCLUSIONS: There was no significant difference between male and female Veterans on M2PI standardized T-scores, which masks differences in response patterns to individual items. Clinical teams should be encouraged to discuss perceived restrictions with patients and target these areas in treatment planning. Future work is needed to investigate the psychometric properties of the M2PI by biological sex.
