What is the early adulthood outcome of boys who bully or are bullied in childhood? The Finnish "From a Boy to a Man" study.

OBJECTIVE. Our goal was to study predictive associations between bullying and victimization at age 8 years and psychiatric disorders in early adulthood. METHODS. The sample comprised 2540 boys born in 1981. Information about bullying and victimization was gathered in 1989 when the boys were 8 years old from parents, teachers, and children. Information about psychiatric disorders was based on military call-up examination and army registry when the subjects were 18 to 23 years old. RESULTS. In univariate logistic regression analysis, frequent bullying-only status predicted antisocial personality, substance abuse, and depressive and anxiety disorders; frequent victimization-only status predicted anxiety disorder, whereas frequent bully-victim status predicted antisocial personality and anxiety disorder. When controlled against the effects of parental education level and parent and teacher reports of emotional and behavioral symptoms by using Rutter scales, frequent victimization-only status predicted anxiety disorders, and frequent bullying-only predicted antisocial personality disorder, whereas frequent bully-victimization predicted both anxiety and antisocial personality disorder. Information about frequent bullying and victimization as primary screening for children at risk identified ∼28% of those with a psychiatric disorder 10 to 15 years later. CONCLUSIONS. Both bullying and victimization during early school years are public health signs that identify boys who are at risk of suffering psychiatric disorders in early adulthood. The school health and educational system has a central role to play in detecting these boys at risk.

Childhood Bullying Behaviors as a Risk for Suicide Attempts and Completed Suicides: A Population-Based Birth Cohort Study

OBJECTIVE There are no previous studies about the association of childhood bullying behavior with later suicide attempts and completed suicides among both sexes. The aim was to study associations between childhood bullying behaviors at age 8 years and suicide attempts and completed suicides up to age 25 years in a large representative population-based birth cohort. METHOD The sample includes 5,302 Finnish children born in 1981. Information about bullying was gathered at age 8 years from self-report, as well as parent and teacher reports. Information about suicide attempts requiring hospital admission and completed suicides was gathered from three different Finnish registries until the study participants were 25 years old. Regression analyses were conducted to determine whether children who experience childhood bullying behaviors are at risk for later suicide attempts and completed suicides after controlling for baseline conduct and depression symptoms. RESULTS The association between bullying behavior at age 8 years and later suicide attempts and completed suicides varies by sex. Among boys, frequent bullying and victimization are associated with later suicide attempts and completed suicides but not after controlling for conduct and depression symptoms; frequent victimization among girls is associated with later suicide attempts and completed suicides, even after controlling for conduct and depression symptoms. CONCLUSIONS When examining childhood bullying behavior as a risk factor for later suicide attempts and completed suicides, each sex has a different risk profile.

Childhood Bullying Behavior and Later Psychiatric Hospital and Psychopharmacologic Treatment Findings From the Finnish 1981 Birth Cohort Study

CONTEXT No prospective population-based study examining predictive associations between childhood bullying behavior and long-term mental health outcomes in both males and females exists. OBJECTIVE To study predictive associations between bullying and victimization in childhood and later psychiatric hospital and psychopharmacologic treatment. DESIGN Nationwide birth cohort study from age 8 to 24 years. PARTICIPANTS Five thousand thirty-eight Finnish children born in 1981 with complete information about bullying and victimization at age 8 years from parents, teachers, and self-reports. MAIN OUTCOME MEASURES National register-based lifetime information about psychiatric hospital treatments and psychopharmacologic medication prescriptions. RESULTS When controlled for psychopathology score, frequent victim status at age 8 years among females independently predicted psychiatric hospital treatment and use of antipsychotic, antidepressant, and anxiolytic drugs. Among males, frequent bully-victim and bully-only statuses predicted use of antidepressant and anxiolytic drugs. Frequent bully-victim status among males also predicted psychiatric hospital treatment and use of antipsychotics. However, when the analysis was controlled with total psychopathology score at age 8 years, frequent bully, victim, or bully-victim status did not predict any psychiatric outcomes among males. CONCLUSIONS Boys and girls who display frequent bullying behavior should be evaluated for possible psychiatric problems, as bullying behaviors in concert with psychiatric symptoms are early markers of risk of psychiatric outcome. Among females, frequent childhood victimization predicts later psychiatric problems irrespective of psychiatric problems at baseline.

Childhood Predictors of Completed and Severe Suicide Attempts: Findings From the Finnish 1981 Birth Cohort Study

CONTEXT To our knowledge, no prospective, population-based study in existence examines predictive associations between early or middle childhood psychopathologic disorders and later completed suicides. OBJECTIVE To study predictive associations between childhood psychopathologic disorders at the age of 8 years and later completed suicides and severe suicide attempts. DESIGN Birth cohort study of individuals 8 to 24 years old. SETTING Finland. PARTICIPANTS The sample includes 5302 Finnish people born in 1981 who were examined at the age of 8 years to gather information about psychopathologic conditions, school performance, and family demographics from parents, teachers, and children. MAIN OUTCOME MEASURES National register-based lifetime information about completed suicides and suicide attempts that prompted hospital admission. RESULTS Of all 24 deaths among males between 8 and 24 years of age, 13 were suicides, whereas of 16 deaths among females, only 2 were suicides. Fifty-four males and females (1%) had either completed suicide or made a serious suicide attempt, defined as a suicide attempt that prompted hospital admission. Of 27 males with completed or serious suicide attempts, 78% screened positive on parent or teacher Rutter scales at the age of 8 years, whereas of 27 females only 11% screened positive. Among males, completed or serious suicide attempt outcome was predicted at the age of 8 years by living in a nonintact family; psychological problems as reported by the primary teacher; or conduct, hyperkinetic, and emotional problems. However, self-reports of depressive symptoms at the age of 8 years did not predict suicide outcome. No predictive associations between the study variables measured at the age of 8 years and suicide outcome were found among females. Male suicide outcome was predicted most strongly by comorbid conduct and internalizing problems. CONCLUSIONS Most males who completed suicide and/or made serious suicide attempts in adolescence or early adulthood had psychiatric problems by the age of 8 years, indicating a trajectory that persists throughout their lives. However, female severe suicidality is not predicted by psychopathologic disorders at the age of 8 years. The results give additional support to the importance of early detection and treatment of psychiatric problems in males.

Childhood bullying behaviors at age eight and substance use at age 18 among males. A nationwide prospective study

Childhood bullying behaviors (bullying and victimization) were studied as risk factors for substance use among Finnish males. The study design was a nationwide prospective general population study, where information was collected in 1989 and 1999. Bullying behaviors and childhood psychopathology at age eight were collected from teachers, parents and boys themselves. At age 18, self-reports of frequent drunkenness (once a week or more often), daily heavy smoking (10 cigarettes or more per day), and illicit drug use during the past six months were obtained from 78% of the boys attending the study at age eight (n=2946). Being frequently victimized at age eight predicted daily heavy smoking, and this was evident even after adjusting for childhood family background, psychopathology at age eight and at age 18, and other forms of substance use. In multivariate analysis, bullying others frequently predicted illicit drug use, while being a victim of bullying associated with a lower occurrence of illicit drug use. Bullying behaviors had no association with frequent drunkenness independent of other factors. Accordingly, being a victim of bullying predisposes in particular to subsequent smoking. Bullying others in childhood can be regarded as an early indicator to illicit drug use later in life. The screening and intervention possibilities in order to recognize the risk group for later health compromising behaviors are emphasized.

Mental health, substance use and suicidal behaviour among young indigenous people in the Arctic: A systematic review

The Arctic has been a subject to various socio-cultural changes; indigenous people living in the region have experienced injustice and oppression in different forms. Furthermore, there are currently various new social, political and environmental challenges. It has been assumed that the continuous socio-cultural transition has an influence on indigenous peoples wellbeing. We conducted a systematic literature review with regard to epidemiological mental health research on Arctic indigenous children and adolescents. The aim was to describe the nature and scope of research conducted and to explore for possible regional and ethnic differences in mental health. It was found that current epidemiological knowledge is based mainly on cross-sectional studies from selected regions and limited to substance use and suicidal behaviour. Youth suicide rates are alarmingly high in many parts of the Arctic, particularly in Greenland and Alaska. Differences between indigenous and non-indigenous groups are also most evident and uniform across suicide studies, with rates being systematically higher among indigenous youth. Substance use is common throughout the Arctic, however, regional and ethnic differences in usage vary considerably. Other psychosocial problems remain largely unexplored. In addition, very little is known about the causes of mental health problems in general and the impact of rapid socio-cultural changes in particular. There are several methodological limitations in the studies included here, many related to the validity of research instruments in different cultural contexts. There is a need for longitudinal comparative studies from the entire Arctic with culturally relevant instruments addressing mental health in early childhood as well.

Cross-informant agreement about bullying and victimization among eight-year-olds: whose information best predicts psychiatric caseness 10–15 years later?

ObjectiveTo examine cross-informant agreement and whose information (parents, teachers, children) about childhood bullying and victimization carry the strongest weight to late adolescent psychiatric outcome. The importance of frequency of bullying in such predictions is addressed.MethodsInformation from 2,713 boys about bullying and victimization at the age of eight was correlated with information about psychiatric disorder at 18–23.ResultsAgreement between informants was poor. Teachers reported higher levels of frequent bullying than others, whereas children reported the highest percentage of victimization. All three informant groups’ reports of “frequent bullying” predicted later psychiatric disorder. Teachers’ reports of “frequent victimization” was the strongest predictor of later psychiatric disorder. Informants’ report about “infrequent bullying” showed at most a rather low risk of adverse outcome. When the associations between bullying/victimization and psychiatric outcome were adjusted with total psychopathology score at age 8, none of the associations remained significant.Conclusion“Frequent bullying” behaviour of boys is a marker of present and later psychopathology. The education system and school health-care service in mid- childhood are of great importance for the early detection of bullying and prevention of later adverse outcomes. A closer integration of these systems in the context of school should be promoted.

Extensive abnormality of brain white matter integrity in pathological gambling.

Several magnetic resonance imaging (MRI) studies in substance use disorders have shown brain white matter integrity abnormalities, but there are no studies in pathological gambling, a form of behavioral addiction. Our objective was to investigate possible changes in regional brain gray and white matter volumes, and axonal white matter integrity in pathological gamblers compared to healthy controls. Twenty-four subjects (12 clinically diagnosed male pathological gamblers and 12 age-matched healthy male volunteers) underwent structural and diffusion weighted brain MRI scans, which were analyzed with voxel-based morphometry and tract based spatial statistics. In pathological gamblers, widespread lower white matter integrity (lower fractional anisotropy, higher mean diffusivity) was seen in multiple brain regions including the corpus callosum, the cingulum, the superior longitudinal fascicle, the inferior fronto-occipital fascicle, the anterior limb of internal capsule, the anterior thalamic radiation, the inferior longitudinal fascicle and the uncinate/inferior fronto-occipital fascicle. There were no volumetric differences in gray or white matter between pathological gamblers and controls. The results suggest that pathological gambling is associated with extensive lower integrity of several brain white matter tracts. The diffusion abnormality closely resembles previous findings in individuals with substance addictions.
