This chapter summarizes current research on the juvenile justice system from an epidemiological perspective. It then takes a global perspective, highlighting recent studies from different international regions to examine the findings of psychiatric morbidity in juvenile justice populations. In the United States, the high rate of imprisonment leads to a significant number of youths with psychiatric diagnoses and placement in the juvenile justice system. In contrast, many European countries have diversion programs that seek to avoid imprisonment when possible.

In the present paper, we describe suicide in youths under 16 years of age and compare their risk factors for suicide to those of older adolescents as described in the literature. Furthermore, we evaluate the possible mislabeling of suicides as accidents, and vice versa. We used the data from a nationwide psychological autopsy of youths 15 years and younger who had committed suicide or died in accidents in Norway from 1993 to 2004 (n = 84). We additionally constructed a suicide index to distinguish between the two causes of death. The young suicide victims presented, with little gender difference, fewer obvious risk factors and less suicide intent than commonly described for older adolescents. The suicide index distinguished quite well between suicides and accidents, with few cases indicating a possible mislabeling, although some suicide cases could have been labeled as uncertain. In line with previous research, suicides in 11-15-year-olds have many similarities to suicides in older adolescents in terms of external circumstances, but they present less apparent warning signs. In our total sample of 84 deaths, there were few indications of incorrect labeling.

The purpose of this study was to gain knowledge about the circumstances related to suicide among children and adolescents 15 years and younger.

Prisoners are associated with high health care needs compared with the general population. This study aims to investigate prisoners' use of health service.

Few longitudinal studies have explored lifetime criminality in adults with a childhood history of severe mental disorders. In the present study, we wanted to explore the association between adult delinquency and several different childhood diagnoses in an in-patient population. Of special interest was the impact of disturbance of activity and attention (ADHD) and mixed disorder of conduct and emotions on later delinquency, as these disorders have been variously associated with delinquent development. Former Norwegian child psychiatric in-patients (n = 541) were followed up 19-41 years after hospitalization by record linkage to the National Register of Criminality. On the basis of the hospital records, the patients were re-diagnosed according to ICD-10. The association between diagnoses and other baseline factors and later delinquency were investigated using univariate and multivariate Cox regression analyses. At follow-up, 24% of the participants had been convicted of criminal activity. In the multivariate Cox regression analysis, conduct disorder (RR = 2.0, 95%CI = 1.2-3.4) and hyperkinetic conduct disorder (RR = 2.7, 95% CI = 1.6-4.4) significantly increased the risk of future criminal behaviour. Pervasive developmental disorder (RR = 0.4, 95%CI = 0.2-0.9) and mental retardation (RR = 0.4, 95%CI = 0.3-0.8) reduced the risk for a criminal act. Male gender (RR = 3.6, 95%CI = 2.1-6.1) and chronic family difficulties (RR = 1.3, 95% CI = 1.1-1.5) both predicted future criminality. Conduct disorder in childhood was highly associated with later delinquency both alone or in combination with hyperactivity, but less associated when combined with an emotional disorder. ADHD in childhood was no more associated with later delinquency than the rest of the disorders in the study population. Our finding strengthens the assumption that there is no direct association between ADHD and criminality.

The mortality in prisoners is high. However, our knowledge about the mortality in convicted offenders, irrespective of incarceration history, is limited. Our aim was to investigate possible predictors for over-all and cause specific mortality in a nation-wide study of convicted offenders with and without previous imprisonment. This case–control study drew random samples of deceased and living offenders (N = 1,112) from four complete cohorts of convicted offenders, two male (born 1967 and 1977, respectively), and two female (born 1967–70 and 1977–80, respectively). All criminal records were systematized and information about date and cause of death was collected on those deceased. Multivariable analyses demonstrated that age at first court conviction (OR = 0.88, 95% CI = 0.84–0.93), drug related crimes (OR = 1.99, 95% CI = 1.23–3.22), and crime diversity (1.51, 95% CI = 1.07–2.13) were significant predictors of premature death in males. In females, age at first court conviction (OR = 0.92, 95% CI = 0.88–0.97), drug related crimes (OR = 2.24, 95% CI = 1.37–3.69) and belonging to the oldest cohort (OR = 2.10, 95% CI = 1.35–3.26) were significant predictors of premature death. Age at first court conviction remained a significant predictor for death in all cause specific multivariable mortality analyses. In addition, having committed drug related crimes and high crime diversity were strong predictors for substance related deaths. Males did more often die in accidents or commit suicide. Somatic deaths were most often encountered in the oldest cohort. Incarceration did not remain a significant predictor for premature death in any of the multivariable analyses. Measures intended to prevent premature death in convicted offenders should target wider populations than hitherto acknowledged.

Incarceration of young people should be avoided according to Norwegian policy. Even so, young people reside in our prisons at all times. Our aim was to investigate their mental health. Among 42 teenage boys (below 20 years of age) remanded to prison, 40 consented to participate in the study. Socio-demographic data were collected and a structured diagnostic instrument (K-SADS) was used to assess their mental health. Only four participants had no mental disorder. The 36 who had mental disorders had a mean of 2.5 diagnoses. The most common diagnosis was substance abuse/dependence (n = 31). 30 of the adolescents had serious conduct disorders and nine of them fulfilled the ICD-10 criteria for a dissocial personality disorder. Anxiety and/or depressive disorders (n = 14) and hyperkinetic disorders (n = 12) were also frequent. Many of the adolescents had unmet treatment needs in addition to large social problems, such as disrupted education and unemployment. Three of four adolescents had an immigrant background. Teenage boys remanded to prison have a variety of complex problems. They have an extensive need for psychiatric treatment, drug treatment, education and employment. This calls for multidisciplinary coordinated interventions to avoid further negative development of chronic maladjustment with substance abuse, mental problems and crime.

Filicide is the tragic crime of murdering one's own child. Previous research has found that the offending parents are commonly depressed and that suicide is often associated as an actual act or an intention. Yet, filicide is an underreported crime and previous studies have been strained with methodological problems. No comprehensive international studies on filicide have been presented in the literature until now. This was a descriptive, comprehensive, register-based study of all filicides in Austria and Finland during 1995-2005. Filicide-suicide cases were also included. Most of the perpetrators were the biological mothers; in Austria 72%, in Finland 52%. Suicide followed filicide either as an attempt or a fulfilled act in 32% and 54% of the cases in Austria and Finland, respectively. Psychotic mood disorders were diagnosed for 10% of the living perpetrators in Austria, and 12% in Finland. Non-psychotic depression was diagnosed in 9% of surviving perpetrators in Austria, 35% in Finland. The data from the two countries demonstrated that filicide is such a multifaceted and rare phenomenon that national data from individual countries seldom offer sufficient scope for its thorough study. Further analyses are needed to produce a complete picture of filicide.
