Abstract

Concern has been raised over alleged increases in antisocial behaviour by military personnel returning from the deployment in Iraq and Afghanistan. US-based research has shown that post-deployment violence is related not only to combat experience, but also to pre-enlistment antisocial behaviour (ASB). This study aimed to examine the association between pre-enlistment ASB and later behavioural outcomes, including aggression, in a large randomly selected UK military cohort. 18.1% were defined as having displayed pre-enlistment ASB. Pre-enlistment ASB was significantly associated with factors such as younger age, low educational achievement, male gender, non-officer rank, Army personnel, being a regular, increasing time spent on the deployment and having a combat role. Pre-enlistment ASB was associated with increased risk of negative behavioural outcomes (severe alcohol misuse, outbursts of anger or irritability, fighting or assaultative behaviour and risk-taking behaviour), after controlling for confounders, suggesting that such background information may identify individuals who are more vulnerable to subsequent behavioural disturbance. The results of this study suggest that those already demonstrating ASB prior to joining the military are more likely to continue on this trajectory, thus emphasising the importance of considering pre-enlistment behaviour when exploring the aetiology of aggression in military personnel.
