Five hundred and sixty caregivers of individuals with TBI were enrolled in this study; 145 also completed a 3-week retest. Details of the sample are provided elsewhere.³⁷

Caregivers of civilians with TBI must have been caring for an individual with a medically documented complicated mild, moderate, or severe TBI, based on TBI Model Systems criteria.⁴⁰ Caregivers of SMVs with TBI must have been caring for a person with a TBI that was medically documented by a healthcare facility. For both subsamples, the caregiver must have been able to read/understand English, and the person with TBI had to be ≥16 years of age at the time of injury and at least one-year post-injury. Caregiver status was defined as providing physical assistance, financial assistance, or emotional support to an individual with a TBI. The study was conducted in accordance with the local institutional review boards and caregivers provided consent before participating in this study.
