Poor Parental Supervision is Associated with Traumatic Brain Injury and Reactive Aggression in Young Offenders

This is the author accepted manuscript. The final version is available from Lippincott, Williams & Wilkins via the DOI in this recordObjective. To establish whether poor parental supervision is associated with head injury and self-reported reactive aggression (i.e. aggression in response to perceived provocation or threat) in adolescents in a young offender’s institute, by examining correlations between these variables. Understanding this population is important as they are at a key pivotal age for intervention to prevent life-long re-offending. Method. Ninety-six male participants aged 16-18 were recruited from a UK Young Offender’s Institute. Self-report measures of remembered parenting, reactive aggression, and head injury history were administered during individual interviews. Results. 74% of participants reported having experienced a lifetime TBI, and 46% of participants reported experiencing at least one TBI leading to a loss of consciousness (LOC). We found that poor parental supervision, length of LOC following TBI, and self-reported reactive aggression, were all positively correlated. Conclusions. Findings show that there are correlational relationships between poor parental supervision, length of LOC following lifetime TBI, and higher levels of self-reported reactive aggression. This suggests there may be pathways resulting from poor parental supervision leading to both TBI with LOC, and reactive aggression. We advocate for future research with longitudinal designs and larger samples to examine the nature of these interactions, and to establish whether poor parental supervision is a prospective risk factor for more TBIs leading to LOC, and reactive aggression. This is key to understanding whether parenting interventions could help to reduce the disabling effects of TBI in adolescents, and help to prevent contact with the law.Barrow Cadbury Trus
