Sonja E. Siennick

Sonja Siennick studies criminal offending and mental health problems in the contexts of the life course and kinship and friendship relations. Her current project, funded by the National Institute of Justice, examines the prevalence and predictors of officially detected recidivism among juveniles. Other recent funded projects have examined the association of solitary confinement with mental health, substance use and peer problems among adolescents with depression, and the effectiveness of a school-based intervention for justice system–involved adolescents.
