Youth showing high aggression AND suicidality (dual harm; 1%) may experience the highest levels of early life adversity; they were also more etiologically similar to youth showing only aggression than those showing primarily suicidality. They also show high negative emotionality and callousness. /5
Dual harm youth (1%) showed high levels of callousness and negative emotions. Aggression profiles (11%) showed moderate levels of callousness and negative emotions. Suicidality profiles (9%) showed low callounsness, moderate anger, and high anxiety/depression symptoms. Early life low income, a deviant best friend, being male, and low positive parenting were associated with youth profiles showing moderate to high aggression. Early life paternal depression symptoms, being female, and low positive parenting were associated with youth profiles showing primarily suicidality.

Suicidality and aggression are related, leading causes of youth death.

Our study looked at how often these forms of harm co-occur in youth and what these harm profiles look like emotionally and etiologically.

Most adolescents showed low aggression and suicidality (~80%). Of those that exhibited harm, most showed either primarily high aggression or suicidality. One percent of all youth showed high levels of both. Low harm youth tended to report less negative emotionality and experienced more positive parenting in childhood. Youth showing aggression reported more callousness, they also had lower incomes and more a more deviant best friend early in life. Some youth showing primarily elevated suicidality had fathers with more depressive symptoms during their childhood.
