The correlates of aggression in people with acquired brain injury: A preliminary retrospective study

Primary objective: To identify correlates of aggressive behaviours in patients with acquired brain injury (ABI).Methods and procedures: During a 16 month period, patients who had ABI and who had been aggressive during hospitalization (n = 32) were identified by hospital staff. A comprehensive chart review of these patients was completed. Results were compared against results of a matched patient sample who had not been aggressive (32).Main outcomes and results: Five variables which were significantly correlated with aggression were entered into a standard logistic regression. The model explained 61.4% of the total variance and successfully predicted 87.5% of the non-aggressive group and 78.1% of the aggressive group. The overall correct prediction rate was 82.8%. Of the five variables, four were found to significantly contribute to the predictive ability of the model: An education of 10 years or less, a history of aggression, dependence on staff for assistance with activities of daily living and a hospita...
