    Objectives Adolescents placed in reform schools (RS) are a special group with a risk for many types of lifetime problems. Previous studies on psychiatric morbidity among RS population indicate a wide spectrum of disorders among this population, but more representative information is needed. This follow-up study investigates the prevalence of psychiatric diagnoses among five cohorts of individuals with a history of RS placement. The prevalence rates are also compared to a matched general population sample. Methods The study sample consisted of a complete national cohort of all 1099 people placed in a reform school on the last day of the years 1991, 1996, 2001, 2006 or 2011, and information on psychiatric diagnoses, grouped into eight categories, was collected from the care register of specialized health care. The reform school subjects were compared to a population control group (n = 5437) matched by age, sex and place of birth, the follow-up time being 18 to 38 years. Results Among the individuals with a RS background, 57.4% had at least one diagnosis during the follow-up time, compared to 6.8% among the controls. 30.1% were diagnosed with conduct disorder and ADHD -category diagnosis, 26.4% with substance use disorder, 16.7% with affective disorder, 9.7% with personality disorder, 8.1% with schizophrenia spectrum disorder, 7.0% with mental retardation, 5.8% with disorder of psychological development, and 8.1% with other childhood disorder. All diagnoses were significantly more prevalent among the RS than control group. Conclusions The results of this study contribute to the earlier knowledge indicating that different psychiatric disorders are highly prevalent in RS population and that problems persist also after RS, reminding about the continuous need for support in this population.

    Objectives. The etiology of juvenile delinquency has been widely researched and several risk factors considering individual traits, parents or parenthood, and other environmental factors have been well established. There has been growing interest in the role of psychopathic traits on young offendings and recent evidence suggests that intensity of psychopathic traits enhances the risk of criminal behaviour in youth. However, the studies investigating the role of psychopathic traits as a predictor of criminal behaviour in youth are methodologically restricted and the effects of risk factors or moderating variables have not been considered comprehensively. The aims of this research were to examine the association between psychopathic traits and criminal behaviour in youth, and to study if risk factors strengthen this association. Methods. This sample consisted of 4855 Finnish students on the ninth grade of upper comprehensive school. Criminal behaviour was measured as the amount of forbidden actions conducted during the past year. Psychopathic traits were studied as a dimensional variable and it was measured with a validated self-report questionnaire for psychopathy (APSD-SR). Linear regressions were used to examine the association between psychopathic traits and juvenile delinquency. Nine different risk factors and cumulativity of risks were controlled for the analyses. Linear regression was also used to examine the moderating effects of risk factors and their cumulativity to the association between psychopathic traits and criminal behaviour. Results and conclusions. Most adolescents reported at least some psychopathic traits. The intensity of psychopathic traits, well established risk factors and the cumulativity of risk factors were all associated with greater amount of criminal behaviour. The association between psychopathic traits and criminal behaviour was enhanced by those risk factors that can be considered to provide antisocial models or opportunities for criminal behaviour. Antisocial peers were the most significant risk factor for criminal behaviour and it strongly enhanced the association between psychopathic traits and criminal behaviour. Overall, the results emphasize the importance of interventions for antisocial peer groups to prevent juvenile delinquency.

    Psychopathy is a disorder characterized with unemotional and callous traits, grandiosity, tendency to lie and manipulate, adventurous and thrill seeking behavior, criminal versatility and unplanned, parasitic lifestyle. Psychopathic personality traits in adolescence are known to be associated with juvenile delinquency and early onset substance abuse. However, based on previous studies, it is difficult to reliably describe the relationship between unique features of psychopathy and the number of offences committed by an adolescent offender. This is mainly because few studies have controlled for the effects of other known factors contributing to antisocial behavior. The same goes for relationship between juvenile psychopathy and substance abuse. There are no published studies investigating the association between psychopathy and the assessment of one´s own overt antisocial behavior. The present study examined the association between psychopathy, number of committed offences and the degree of substance abuse among incarcerated juvenile offenders. The present study used data from the American Pathways to Desistance -research project where 14-18 years old adolescents (n = 1354) who had been found guilty for at least one serious offence were followed. The associations between psychopathic personality traits – as evaluated with PCL-YV method – and a) number of subject´s self-reported offences b) extent of subject´s self-reported substance abuse were examined with linear regression models that controlled for number of known correlates for antisocial behavior. The same analyses were carried out for discrepancy between subject´s and his/hers collateral reports regarding subject´s offending and substance abuse. Psychopathy was associated with the extent of illicit drug abuse but not alcohol consumption. Psychopathy did not explain the discrepancy between subject´s and his/hers collateral´s reports regarding subject´s substance abuse. Psychopathic traits were positively associated with the number of self-reported offences committed by the subject. In regard to number of offences committed, the discrepancy between subject´s and collateral´s reports were greater with those subjects who had higher levels of psychopathic traits. The results further support the validity of psychopathy as a construct that is uniquely associated with juvenile delinquency and illicit drug abuse. In addition, this study lends support to notion that psychopathic individuals seem to lie about their actions mainly when they perceive they can somehow benefit from it.
