Dual harm refers to the co-occurrence of self-harm and aggression towards others during an individual’s lifetime. Rather than engage in self-harm alone or aggression alone (sole harm), a subset of individuals will engage in dual harm behaviour. There is growing evidence that those who engage in dual harm represent a unique high-risk group that differ from those who engage in sole harm behaviours. As such, it may be that dual harm should be understood as an independent clinical construct that stands separate from sole harm. Nonetheless, little research to date has investigated dual harm and there is a lack of an agreed definition of this behaviour in the literature. It is unclear which harmful behaviours should be included in the conceptual definition of dual harm. It is important to investigate how different harmful behaviours may be connected to each other to extend our understanding of how dual harm can be meaningfully defined. Therefore, we will use data from the Avon Longitudinal Study of Parents and Children (ALSPAC, Golding, Pembrey & Jones, 2001) to investigate how self-harm and different types of antisocial behaviours are interrelated with each other in a network model. By mapping the degree of interconnection between different types of harmful behaviours, we will be able to provide evidence for how dual harm may be best defined.
