Brain injury and discrimination: Two competing models-perceptions of responsibility and dangerousness

(1) To examine whether the willingness of people to socialize with adolescents with brain injury is influenced by gender, visibility of injury and/or knowing how to interact with people with brain injury; and (2) To consider two models: the responsibility model (attributions about the cause of a condition) and the danger appraisal model (perceptions of dangerousness due to anger/aggression) for their effect on willingness to socialize and to understand how these perceptions lead to avoidant behaviour.

Participants were recruited either by personal approach or via Facebook advertising and completed a survey after reading a brief vignette and seeing a photo of an adolescent male or female, with or without a head scar. Vignettes for some participants were varied to represent perceptions of responsibility and dangerousness Main outcomes and results: ANOVAs and structural equation modelling revealed that participants were more willing to socialize with the adolescents with a scar than with no scar. Knowledge about how to interact with survivors impacted willingness to socialize, but familiarity did not. The full danger appraisal model was supported, but only some aspects of the responsibility model were supported.

The results provide useful information for rehabilitation health professionals working with survivors of brain injury. The implications of these findings are discussed with regards to assisting adolescents' re-entry into society post-injury.
