An ongoing study follows the same individuals over several decades to investigate how childhood maltreatment – physical, emotional and sexual abuse and neglect – effects the child’s future and how those that have overcome a bad childhood have done it.
"Child abuse is a risk factor for later antisocial behavior," said study co-author Todd Herrenkohl, the Marion Elizabeth Blue Professor of Child and Family at the University of Michigan School of Social Work. "Education and academic achievement can lessen the risk of crime for all youth, including those who have been abused (encountered stress and adversity)."
The researchers also investigated effects on physical and mental health, drug and alcohol abuse, intergenerational transmission of violence, and socioeconomic disadvantage.
Previous studies on child maltreatment didn’t distinguish youth and adult chronic offenders from non-offenders and those who perpetrate antisocial behavior in adolescence only, who are called desisters.
"Given that offending in adolescence can persist into adulthood if left unaddressed, it is important to identify and act on factors that predispose individuals to ongoing patterns of antisocial behavior," said Hyunzee Jung, the study's lead author and a U-W researcher.
Data involved 356 people from childhood (ages 18 months to 6 years) in 1976–1977, school-age (8 years) in 1980–1982, adolescent (18 years) in 1990–1992 and adulthood (36 years) in 2010.
Parent reports, self-reports – which included crime/antisocial behavior – and parent-child interactions measured various types of abuse and neglect, and responses also factored educational experiences and criminal behavior against others or property.
The abuse made for criminality, but this was not the case for those who had been neglected in their early years, the study shows.
Successful school experiences kept teens from both committing crimes and having antisocial behaviors. But for youths suspended in grades 7 to 9, the chronic offending habits and antisocial behaviors continued later in life.
Herrenkohl said the primary prevention of child abuse is a critical first step to reducing antisocial behavior at the transition from adolescence into adulthood.
"Strategies focused on helping school professionals become aware of the impacts of child abuse and neglect are critical to building supportive environments that promote resilience and lessen risk for antisocial behavior," he said.
The study, whose other authors are University of Washington researchers Martie Skinner and Ashley Rousson, appears in the Journal of Interpersonal Violence.
