Background:
To examine the associations between the functioning of patients with severe traumatic brain injury (TBI), and their relatives' coping style and quality of life across 12 months post-injury.
Methods:
Prospective, population-based cohort study assessing 188 patients with severe TBI (Abbreviated Injury Scale of the head region [HAIS] score >3), and their relatives, 3, 6 and 12 months post-injury. Data were drawn from a larger national study run in Switzerland (2007-2011). Patient assessment: Glasgow Coma Outcome Scale Extended (GOSE), Patient Competency Rating Scale for Neurorehabilitation (PCRS-NR). Relative assessment: Health-Related Quality of Life (HRQoL; 12-item short form health survey [SF-12]), Coping Inventory for Stressful Situations (CISS). Mixed linear models were run separately for ages >50 and ≤50 (i.e. bimodal distribution).
Results:
Patients' GOSE score was associated with relatives' reported mental SF-12 scores across age (ps < 0.01). Relatives' CISS was associated with patients' PCRS score (age > 50 years): Total and cognitive functioning decreased as emotion-oriented coping increased (ps = 0.01), while interpersonal functioning increased as task-oriented coping increased (p = 0.01) and decreased as avoidance-oriented coping increased (p = 0.02).
Conclusion:
Patients' functioning and relatives' mental HRQoL and coping strategies are associated with each other.
