support for this hypothesis comes from a study by gilliom et al. (2002) in which children's ability to manage anger in a frustration task was examined. attachment was assessed at the age of 18 months in a sample of 310 boys, who were followed up until the age of 6 wgen performance on the frustration task was assessed. children who were assessed as insecurely attached to seek support and to disengage from the as opposed to expressing inappropriate levls of anger. furthermore, studies of children experiencing attachment difficulties have found them to be significantly more disruptive, aggressive and antisocial. in adults, fossati et al. (2009) found a relationship between insecure attachment and impulsive aggerssion and critchfield et al. (2008) found an association between high levels of attachment anxiety and avoidance and multiple forms of aggressive behavior (e.g verbal assault, physical assault, and self harm) in a sample of participants with borderline personality disorder.
