This study examines the relationship between several factors which have been identified in previous research as co-occurring and risk relevant to aggressive behavior. Although many factors have been addressed independently for various reasons in other studies, this study looks at the unique combination of a select few of these variables and their relationship for propensity towards aggression. The results of this study show propensity towards aggression is significant for two specific mental health issues; anxiety, and history of severe head injury. Results also indicate that co-occurring factors are prevalent in this sample and those inmates with prior mental illness are likely to exhibit aggression. Significant correlations for co-occurring factors were also found. Inmates with co-occurring factors may benefit from more purposive treatment and risk assessment to identify and treat their aggressive behavior
