Burden among caregivers of service members and veterans following traumatic brain injury
Bibliographic record
Abstract
OBJECTIVES: To determine the (a) health status and caregiving appraisal and (b) influence of perceived burden on health and appraisal in a sample of caregivers helping service member/veterans (SMVs) following a traumatic brain injury (TBI). METHODS: Participants were caregivers (N = 283, female = 96.1%, 86.2% = spouse/partner) of SMVs who sustained a mild-severe or penetrating TBI. Participants completed the Caregiver Appraisal Scale (CAS) and the SF-36v2 Health Survey (SF-36v2). Participants were divided into three burden groups: high, neutral, and low. RESULTS: Almost half the sample (48.8%) reported negative feelings on the CAS Perceived Burden scale. A substantial proportion had lower scores than a normative sample on four SF-36v2 physical health scales (35.1-64.5%) and four mental health scales (70.7-79.8%). A significant main effect was found across caregiver burden groups on three CAS scales (p = 0.010 to p < 0.001), two SF-36v2 component scores (all ps < 0.001), and eight SF-36v2 scales (p = 0.001 to p < 0.001). Caregivers with high perceived burden reported significantly worse scores, except CAS Caregiving Ideology. All CAS and SF-36v2 scales were significant predictors of CAS Perceived Burden scores (all ps< 0.001), with the SF-36v2 Social Functioning scale accounting for the most variance (32.6%). CONCLUSIONS: Health care and social services are needed for caregivers who help SMVs to foster resilience, wellness, and growth.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
