This study investigated the associations of adolescent aggression, and criminality, to severe hospital-treated assault exposures among young adults (n = 508) with a history of adolescent psychiatric inpatient treatment between 2001‐2006. Participants were interviewed during hospitalization using K–SADS–PL to assess psychiatric disorders, and to obtain information on aggressivity. Data on crimes committed were obtained from the Finnish Legal Register Centre, and the treatment episodes for assault exposures from the Finnish National Care Register for Health Care, up to end of 2016. Predictors for severe assault exposure were male sex (OR = 2.1), short temperedness (OR = 2.4), non-violent offending (OR = 2.6), and violent offending (OR = 4.8). These results indicate that the participants most vulnerable to severe assaults were those suffering from a continuum of aggressivity across their lifetime. Our findings can be utilized to identify adolescents at risk of severe assault exposure, and to reduce this risk by focusing on appropriate treatments for these vulnerable adolescents.
