Contributing factors to the persistence of musculoskeletal pain in preadolescents: a prospective 1-year follow-up study.

&NA; A 1‐year follow‐up of two preadolescent age cohorts with musculoskeletal pain at least once a week was conducted to analyze predictive factors for the persistence of musculoskeletal pain. Of the 564 children with pain at baseline, representing one third of the sample studied, 515 (91.3%) could be followed and 452 (80.1%) children with complete data were included for the logistic regression analysis. A structured questionnaire included questions on pain and also on several psychosomatic symptoms and amount of exercise. Joint hypermobility together with the questionnaire data were included in the logistic regression analysis. One half of subjects with pain at baseline still reported pain at follow‐up, indicating persistent pain. Boys had a lower risk for the persistence of pain than girls and the risk for the persistence of pain increased 1.2 times per age year. When further adjusted for all the other studied risk determinants, high subjective disability index due to pain (OR 3.2, 95% CI 1.5–6.6) and day tiredness (OR 1.9, 95% CI 1.2–3.0) were the most significant predictors. This might indicate that psychological distress contributes to the persistence of non‐specific musculoskeletal pain of different locations in preadolescents. In clinical work not only pain but its interference with daily activities should be noticed.

Psychosocial risk factors associated with cyberbullying among adolescents: a population-based study.

CONTEXT To our knowledge, no population study examining psychosocial and psychiatric risk factors associated with cyberbullying among adolescents exists. OBJECTIVE To study cross-sectional associations between cyberbullying and psychiatric and psychosomatic problems among adolescents. DESIGN Population-based cross-sectional study. SETTING Finland. PARTICIPANTS The sample consists of 2215 Finnish adolescents aged 13 to 16 years with complete information about cyberbullying and cybervictimization. MAIN OUTCOME MEASURES Self-reports of cyberbullying and cybervictimization during the past 6 months. RESULTS In the total sample, 4.8% were cybervictims only, 7.4% were cyberbullies only, and 5.4% were cyberbully-victims. Cybervictim-only status was associated with living in a family with other than 2 biological parents, perceived difficulties, emotional and peer problems, headache, recurrent abdominal pain, sleeping difficulties, and not feeling safe at school. Cyberbully-only status was associated with perceived difficulties, hyperactivity, conduct problems, low prosocial behavior, frequent smoking and drunkenness, headache, and not feeling safe at school. Cyberbully-victim status was associated with all of these risk factors. Among cybervictims, being cyberbullied by a same-sex or opposite-sex adult, by an unknown person, and by a group of people were associated with fear for safety, indicating possible trauma. CONCLUSIONS Both cyberbullying and cybervictimization are associated with psychiatric and psychosomatic problems. The most troubled are those who are both cyberbullies and cybervictims. This indicates the need for new strategies for cyberbullying prevention and intervention.

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.

The Strengths and Difficulties Questionnaire among Finnish school-aged children and adolescents.

Abstract The emotional and behavioural problems of 7- to 15-year-old Finnish children and adolescents (n = 735) were assessed in a community population by a brief screening instrument, the Strengths and Difficulties Questionnaire (SDQ). The parent-, teacher- and self-reports of the SDQ were obtained. The results show that for the total scores, the inter-rater agreement between the pairs of reports was 0.38–0.44. The internal consistency in all three questionnaires was 0.71. Functioning above the 90th percentile of the SDQ total difficulties scores in parent-, teacher- and self-reports was strongly associated with help-seeking variables and problematic behaviour according to parents. The correlation of the parental SDQ total scores and the Child Behaviour Checklist total scores was 0.75 and the correlation of the self-report SDQ total scores with the Youth Self Report total scores was 0.71. The differences in sex, grade and informants of the SDQ total difficulties scores are reported. The study gives further evidence of the usefulness of the SDQ as a promising screening instrument for epidemiological research and clinical purposes.

Parent-adolescent agreement on emotional and behavioral problems

Background: The aim of the study is to report parent/youth self-report agreement on emotional and behavioral symptoms among 15- to 16-year-old adolescents. Methods: A completed Child Behavior Checklist and Youth Self-Report were obtained from 580 subjects. Results: Adolescents reported significantly more problem behaviors than their parents. Adolescent girls reported a significantly higher level of distress than boys in most symptom domains. The discrepancies between parent reports and youth self-reports were greater, especially for internalizing symptoms, for girls than for boys. Conclusions: Many adolescents in need of psychiatric assessment do not receive appropriate help because their problems remain unnoticed by adults. Internalizing problems among girls seem especially likely to remain unrecognized by adults.

The Strengths and Difficulties Questionnaire in the Nordic countries

Abstract.Background:The Strengths and Difficulties Questionnaire (SDQ) has been translated into the different Nordic languages between 1996 and 2003. During the past few years, SDQs have been completed for nearly 100,000 children and adolescents in population-based studies as well as in clinical samples. The largest studies have been performed in Norway and Denmark, and in these countries the diagnostic interview DAWBA has also been used in conjunction with the SDQ.Aims:In addition to a brief overview of past and ongoing SDQ work in Sweden, Finland, Norway, Denmark, and Iceland, we present scale means and standard deviations from selected community studies with comparable age groups, including parental reports for 7, 9 and 11 year-old children and self-reports of 13 and 15 year-olds.Conclusions:The descriptive statistics suggest that the distributions of SDQ scores are very similar across the Nordic countries. Further collaborative efforts in establishing norms and evaluating the validity of the SDQ as a screening instrument are encouraged.

Antenatal depression, substance dependency and social support

BACKGROUND The purpose of this study was to explore the prevalence of depression and factors associated with depressive mood among pregnant women. METHOD 391 women who were 14-37 weeks pregnant were evaluated with the Edinburgh Postnatal Depression Screen (EPDS), which has also been validated for prenatal use. Four questionnaires were used in order to explore associated factors: a questionnaire on background and pregnancy data, the Substance Abuse Subtle Screening Inventory (SASSI) and two Social Support Questionnaires (SSQ1 and 2). RESULTS 7.7% of the total sample screened positive on the EPDS with a cut-off point of 12/13 recommended. Substance dependency and experienced difficulties in social environment had an independently significant association with maternal depression. LIMITATION The caseness was defined with a self-report instrument. CONCLUSION Substance dependency and experienced difficulties, especially in relation to friends, partner and own mother, are associated with antenatal depression. It is important to be aware of this when developing interventions in maternity care primary units.

The Strengths and Difficulties Self-Report Questionnaire as a screening instrument in Norwegian community samples

Abstract.This study reports on the application of the Norwegian self-report version of the Strengths and Difficulties Questionnaire (SDQ-S). The application of the SDQ-S was not motivated by a wish to reveal the prevalence of psychiatric disorders, but rather to set the stage for routine screening as part of schools’ efforts to inform themselves about the life of adolescents at school. The survey included 4167 young people aged 11 to 16 years, attending 66 primary and secondary schools in Northern Norway. The respondents comprised 80.2% of the total population in these grades in the target area. Structural analysis of the instrument, including confirmatory factor analysis, internal consistency and intra- and cross-scale correlations revealed somewhat variable psychometric properties. Model modification suggested several ways of improving the structural psychometric properties of the SDQ-S. Norwegian cut-off points were similar to those found in other Scandinavian studies. About one third of the subjects reported at least minor perceived difficulties, while about 5% reported definite or severe difficulties. These difficulties were strongly associated with all symptom scales. Girls reported a significantly higher level of emotional problems and better prosocial functioning. Boys reported significantly higher scores on the externalising scales and on peer problems. The SDQ-S may be judged as an efficient and economical screening instrument for preventive research on large community samples. However, efforts should be made to improve its psychometric structure.

Childhood bullying as a risk for later depression and suicidal ideation among Finnish males

BACKGROUND Little is known about the predictive association between childhood bullying behavior with depression and suicidal ideation at age 18. METHODS The sample included 2348 boys born in 1981. Information about bullying was gathered at the age of 8 from self, parent and teachers reports. Depression and suicidal ideation were assessed during the Finnish military call-up examination. RESULTS Based on regression models, boys who were bullies frequently, but not merely sometimes, were more likely to be severely depressed and to report suicidal ideation compared to boys who were not bullies. When controlling for depression at age 8 the association between frequent bullying and severe depression was maintained but the association with suicidal ideation became non-significant. Boys who were only victimized were not more likely to be depressed or to report suicidal ideation at age 18. Boys who were frequently both bullies and victims were found to be at risk for later depression. LIMITATIONS Our finding can only be generalized to boys who were involved in bullying at elementary school age. Data at age 18 was based only on self-reports and the bullying/victimization questions were very general. CONCLUSIONS Childhood bullying behavior is a risk factor for later depression. Screening and intervention for bullying behavior in the early school years is recommended to avoid subsequent internalizing problem in late adolescence.
