Associated outcomes
Not all people who experience child maltreatment have the same outcomes.
Sexual abuse and emotional abuse are the most harmful types of child maltreatment. Multi-type maltreatment is also strongly associated with more damaging outcomes. However, maltreatment does not mean someone is destined to have adverse outcomes.
Outcomes depend on many factors, including:
01
The severity and frequency of the abuse
02
The child’s characteristics
03
Protective factors in the family
04
Protective factors at school and in the community
The harmful outcomes of child maltreatment begin in childhood, and are typically lifelong.
Children and young people who do not experience child maltreatment have much lower prevalence of mental disorders and health risk behaviours.
In contrast, young people aged 16-24 who experienced any child maltreatment are:
2.9
times more likely to have any mental disorder
2.7
times more likely to have major depressive disorder
3.3
times more likely to have generalised anxiety disorder
4.1
times more likely to have severe alcohol use disorder
5.8
times more likely to have post-traumatic stress disorder
6.5
times more likely to be dependent on cannabis
4.5
times more likely to have attempted suicide in the past 12 months
3.5
times more likely to have self-harmed in the past 12 months
