Abstract:

Study examined whether caregiver/family status can predict the well-being of individuals with brain injury and whether perceived social support to caregivers moderates their well-being. Participants were 109 pairs of adults, consisting of a caregiver and an individual with traumatic brain injury (TBI). Participants completed the following outcome measures: Brief Symptom Inventory-18, Satisfaction With Life Scale; Disability Rating Scale; Social Provision Scale, Family Assessment Device, Disability Rating Scale, and an index of the neuropsychological functioning of the person with TBI. Canonical correlation indicated the presence of a relationship between well-being in TBI and caregiver participants. Two canonical variates accounted for 47.5 percent variance. Poor psychological well-being among subjects with TBI was associated with poor caregiver perceived social support and poor familial behavioral control. Individuals with high disability also had caregivers with poorer psychological well-being. In post hoc multiple regressions, caregiver/family psychosocial characteristics added unique prediction of outcome for individuals with TBI. Hierarchical multiple regressions provided evidence that social support of caregivers moderates outcome status for individuals with TBI.
