To date, a significant proportion of research has predominantly focused upon childhood abuse and neglect (CAB) without considering the impact of exposure to wider forms of trauma. This thesis therefore examines the impact of exposure to recurrent CAN and multiple traumatisation (i.e. exposure to recurrent CAN and at least one wider form of trauma) upon emotion regulation (ER) and the perpetration of violence. Chapter Two presents a systematic review that explored the literature on factors associated with the impact of recurrent CAN in comparison to multiple forms of victimisation among an adolescent and young adult population. Chapter Three explores the construct of coping and critiques the Brief COPE (Carver, 1997) assessment. Chapter Four presents an empirical paper exploring the impact of recurrent CAN and multiple traumatisation on ER and coping, in addition to the role of ER in relation to aggressive behaviour among university students (n=237) and the general population (n=95). Statistically significant findings demonstrated that both recurrent CAN and multiple traumatisation were predictive of difficulties both in ER and violent behaviour. A number of further variables including optimism, violent attitudes and level of education were also found to contribute to difficulties in ER and violent behaviour.
