Professionals working with young people often encounter individuals who pose a risk of violence to others. Risk evaluation in those under 18 differs in a number of respects when compared to adults. Assessment must ultimately lead to risk management strategies. The current trend is to make structured professional judgements. Violence risk assessment also needs to take into account the presence or absence of protective factors. Evaluation of violence risk in young people requires a formulation about the likelihood of a specific future risk and in what circumstances and time frame. There are several structured assessment tools designed for use with young people. Some of these tools include: the Structured Assessment of Violence in Youth (SAVRY), and the Early Assessment Risk List for Boys (EARL-20B). More generalized personality assessment tools such as the Millon Adolescent Clinical Inventory (MACI) may also facilitate a deeper psychological understanding of a young person's needs.
