ObjectivesTo determine predictors of self-esteem and behavioral outcome among siblings of children with traumatic brain injury (TBI).DesignCross-sectional.ParticipantsThirty-nine siblings closest in age to a child who sustained moderate to severe TBI.MeasuresOutcome Variablessibling behavior (Child Behavior Checklist-Revised) and self-esteem (The Self-Perception Profile for Children-Global Self-Worth).Predictor Variablessocial support (The Social Support Scale for Children), knowledge (The Child TBI Knowledge Questionnaire), injured child behavior (Child Behavior Checklist-Revised), injured child adaptive skills (Adaptive Behavior Assessment System II-Practical Component), severity of injury (Glasgow Coma Scale), injured child age at injury, time since injury, family functioning (The Family Adaptability and Cohesion Evaluation Scales II - Cohesion Subscale), and socio economic status.ResultsSignificantly reduced self-esteem, but no evidence of behavioral difficulties, were found in siblings of children who had sustained TBI. Sibling self-esteem did not correlate with any other study variables. Behavioral outcome correlated with: sense of social support, knowledge about TBI and injured child behavior. Nevertheless, simultaneous regression analyses revealed that only knowledge about TBI and sense of social support made significant independent contributions to behavioral outcome.ConclusionsEducating uninjured siblings about TBI and raising awareness of their needs in members of their social support network may be important in facilitating sibling behavioral outcome.
