Childhood psychopathology and sense of coherence at age 18: findings from the Finnish from a boy to a man study

Incidence and comorbidities of disruptive behavior disorders diagnosed in Finnish specialist psychiatric services

PURPOSE

Disruptive behavior disorders (DBD), including oppositional defiant disorder (ODD) and conduct disorder (CD), are some of the most common psychiatric conditions in childhood. Despite this, there has been limited research on DBDs. We examined the incidence, comorbidity and gender differences of DBDs diagnosed by specialist services.

METHOD

This was a nationwide register study of 570,815 children and adolescents born in 1996-2005. The 7050 individuals diagnosed with DBD by specialist healthcare services were matched to 26,804 controls.

RESULTS

By the age of 15, the cumulative incidence of diagnosed DBDs was 3.5% for boys and 1.4% for girls. The yearly incidence rate increased for girls after 13 years of age, while the incidence for boys was relatively stable between 8 and 15 years of age. When we compared subjects born between 1996-1998 and 1999-2001, we found that by the age of 12, the cumulative incidence per 100 people had increased from 0.56 to 0.68 among girls and from 2.3 to 2.6 among boys. This indicated a minor increase in treated incidence. The parents of children diagnosed with DBDs had lower educational levels than the parents of controls. Children with DBD were also more likely to have been diagnosed with other psychiatric disorders.

CONCLUSION

Although DBDs were 3.5 times more common among boys during the whole follow-up period, the yearly incidence during adolescence was fairly similar between boys and girls. DBD existed alongside various psychiatric disorders at a relatively young age and only a minor increase in treated incidence was found during childhood.

What is the long-term outcome of boys who steal at age eight? Findings from the Finnish nationwide "From A Boy To A Man" birth cohort study

OBJECTIVE

The aim was to study predictive associations between childhood stealing behavior at the of age 8 years with later psychiatric disorders, criminality or suicide attempts and completed suicides up to the age 25 years in a large representative population-based birth cohort.

METHOD

The sample includes 2,592 Finnish males born in 1981 with information about stealing from both parents and teachers. Information about psychiatric disorders, criminality, suicide attempts requiring hospital admission and completed suicides was gathered from four different Finnish nationwide registries until the study participants were 25 years old.

RESULTS

One out of ten boys had stealing behavior during the previous 12 months. After adjusting for parental education level and conduct problems or hyperactivity (i.e. potential confounds), stealing at eight independently predicted substance use and antisocial personality disorders, and high level of crimes. Stealing was also associated with completed suicide or severe suicide attempt requiring hospital admission. Comorbid stealing and frequent aggression had the strongest predictive association with any psychiatric diagnosis, crime and completed suicide or severe suicide attempt, while stealing without aggression was not associated with any of the negative outcomes.

CONCLUSIONS

Stealing accompanied with aggressivity at age eight is predictive of wide range of adversities. However, no increased risk was observed among the group with stealing behaviors but without aggression.

Psychosocial factors associated with becoming a young father in Finland: a nationwide longitudinal study

Background

Little is known about the characteristics of boys who become fathers at young age. Some studies have suggested that antisocial adolescents are more likely to be young fathers. The aim of this study was to examine the associations of psychosocial factors in childhood with becoming a young father, and to assess if they are independent of criminal behavior in adolescence.

Methods

The baseline assessment in 1989 included 2,946 boys born in 1981. Information about psychiatric symptoms at age eight was collected with Rutter questionnaires from parents and teachers and with the Child Depression Inventory from the children themselves. Data on criminal offenses at age 16–20 was collected from a police register. Register-based follow-up data on becoming a father under the age of 22 was available for 2,721 boys.

Results

The factors measured at age eight, which were associated with becoming a young father independently of adolescent criminality, were conduct problems, being born to a young father and having a mother with a low educational level. Having repeatedly committed criminal offences in adolescence was associated with becoming a young father independently of psychosocial factors in childhood.

Conclusions

Antisocial tendencies both in childhood and adolescence are associated with becoming a young father. They should be taken into consideration when designing preventive or supportive interventions.

Behaviour problems in Chinese primary school children

PURPOSE

This study aimed to determine levels of behaviour problem in primary school children, and to explore key determinants relevant to the Chinese context: being an only child, urban living, school stressors, being bullied and physical punishment.

METHODS

We administered a child self-completion questionnaire to children aged 7-13 and Rutter Parent Scales to their parents in nine primary schools, in urban and rural Zhejiang Province, eastern China.

RESULTS

Full data were available for 2,203 child-parent pairs. Rutter Scores showed that 13.2% of the children (16.4% of boys, 9.4% of girls) had a behaviour problem. Girls manifest more emotional problems (5.3 vs. 2.3%) and boys more conduct problems. Questions about school stress showed that 78% worry "a lot" about exams, 80% felt pressure to perform at school "all the time", and 44% were bullied at least sometimes. Seventy-one percent were sometimes or often physically punished by their parents. Conduct problems were strongly significantly associated with male gender (OR 3.8 95% CI 3.0-4.6), rural residence OR 2.3, 1.3-3.4, having been bullied (1.8, 1.5-2.2) and frequent physical punishment (4.5, 3.2-5.8). Emotional problems were most strongly associated with being bullied (OR 4.9, 2.3-7.7). Being an only child was not associated with behaviour problems.

CONCLUSIONS

High levels of behaviour problems in these Chinese children could relate to high expectations in a very competitive educational environment. Our results raise concerns for the future mental well-being of those children with behaviour problems.

Growing up in the shadow of Chornobyl: adolescents' risk perceptions and mental health

PURPOSE

Despite long-term research on risk perceptions of adults after ecological disasters, little is known about the legacy for the generation exposed to toxic elements as infants. This study examined Chornobyl-related risk perceptions and their relationship to mental health in adolescents raised in Kyiv in the aftermath of the accident.

METHODS

Risk perceptions, 12-month DSM-IV major depression (MDD)/generalized anxiety disorder (GAD), and current symptomatology were examined in 265 evacuee adolescents, 261 classmate controls, and 327 population-based controls 19 years after the accident. Competing risk factors, including maternal risk perceptions and MDD/GAD, were taken into account.

RESULTS

Significantly more evacuees (48.7%) than controls (33.4-40.0%) reported at least one negative perception of Chornobyl; 18.1% of evacuees versus 10.0-12.8% of controls reported 2-4. In contrast, 75.7% of evacuee mothers versus 34.8-37.6% of controls endorsed 2-4 negative perceptions. In the unadjusted analyses, adolescents' perceptions were associated with both MDD/GAD and symptomatology. After adjusting for competing risk factors, their perceptions were associated with symptomatology only (p < 0.01). Among the competing risk factors, gender, self-esteem, life events, and peer support were significantly associated with MDD/GAD. These measures, along with quality of parental communication, father belligerence when drunk, and maternal MDD/GAD, were significantly associated with symptoms.

CONCLUSIONS

More evacuee teens reported negative risk perceptions than controls, but these perceptions were only modestly associated with mental health. Instead, the strongest risk factors comported with epidemiologic studies conducted in other parts of the world. Research is needed to determine whether children raised in the aftermath of other ecological disasters demonstrate similar resilience.

Brief report: adolescents under missile attacks: sense of coherence as a mediator between exposure and stress-related reactions

Employing the salutogenic approach (Antonovsky, 1987), this pilot study aimed at exploring the mediation effect of Sense of Coherence (SOC) on the relationships between exposure to missile attacks and stress-related reactions among adolescents. A strong SOC means a tendency to see the world as more comprehensible, manageable and meaningful. Data were gathered during August 2006 (Second Lebanon War) from 230 Israeli adolescents, 12-18 years old. Adolescents filled out self-reported questionnaires, including demographics, level of physical exposure, SOC, Scale of Psychological Distress (SPD), State Anxiety and State Anger. Exposure to missile attacks was found to be significantly positively linked to stress reactions; exposure was negatively linked to SOC which was also negatively linked to stress reactions. The mediation hypothesis was supported, with SOC mediating the effect of exposure to missile attacks on stress reactions. It seems that SOC may have a protective effect against stress reactions among adolescents exposed to political violence. This should be further studied in a longitudinal research.
