  Identifying children with symptoms of anxiety before they develop clinical disorders is important. The objective of our study was to examine the latent factor structure of the MASC (youth report version) in a large self-selected sample of school children in 4th to 6th grade, and examine if the measure had a comparable factor structure for gender and age. Gender and age differences in anxiety symptoms were also examined. Children (N = 1686, 53.8% female) were recruited from schools during pretest of an ongoing randomized, controlled, indicative intervention. Latent variable modelling was used to determine the underlying concepts of the MASC. We found good model fit for the four-factor model, however some items on the Harm/Avoidance scale had low factor loadings. Invariance analysis indicated that the MASC had similar factor structure (comparable meaning) for boys and girls and for younger and older children in this sample. Girls scored significantly higher than boys on all subscales and on the Total Anxiety scale. Age differences were only found on the Separation Anxiety scale. Overall, the original four-factor structure of the MASC was confirmed within a large sample of school children and was invariant across gender and age. However, the Harm/avoidance scale warrants some attention. The MASC is a potentially useful measure to be used for screening purposes in a school setting.

  Impulsive/disinhibitory personality traits have consistently been associated with externalizing symptomatology such as delinquency and substance use problems, often starting in adolescence. Yet the etiological nature of this co-occurrence is not well understood. Using a classic twin study design with self-report data from 717 male and female twin pairs, aged 15–18 years, a hierarchical psychometric model was examined. In this model the shared variance and etiological structure between control, delinquency and substance abuse symptoms, was modeled through a common externalizing factor. Model fitting indicated that the genetic and environmental influences differed in strength between male and female adolescents. The heritability of the externalizing factor was 45% in males and 10% in females, though neither was statistically different from zero. A statistically significant influence of shared environmental factors was seen for both sexes, 21% in males and 54% in females. In both sexes, the externalizing factor accounted for little variance in control, indicating a weak association and little shared etiology with externalizing liability. These results illuminate further that facets of impulsivity are differentially associated with vulnerability for externalizing symptomatology.

  Heritability estimates for adolescent anxiety vary across studies, partly depending on who is rating thesymptoms. The goal of our study was to estimate genetic and environmental influences using a multi-informant design with responses from a population-based sample of adolescent twins, their mothers andtheir fathers (N = 1394 families).Results from multivariate biometrical modeling indicated quantitative, but no qualitative sex differ-ences in etiology. The best fitting model was an AE Common Pathway model, defining anxiety as a latentfactor common to all informants. This model offers error free estimates of genetic and environmentalinfluences explaining the latent factor variance.Variation in the latent factor was highly genetic, with heritability estimates of 65% for boys and 74%for girls. Non-shared environmental effects explained the remaining variance. In addition, there weresignificant rater-specific genetic and environmental effects for both sexes.The observed rater differences underline the importance of using several informants when studyingadolescent anxiety.

  The purpose of this study was to investigate the possible academic and classroom climate effects of the universal school program Zippy's Friends, the primary objective of which is to strengthen children's ability to cope with stress. The sample consisted of 1483 children (aged 7–8 years) from 91 second-grade classes in 35 schools. The schools were matched and randomly assigned to intervention and control conditions. Classroom social climate and academic skills were assessed by the teachers and the children using an adapted version of the German scale SIKS (Social Integration, Classroom Climate and Self-concept of School Readiness). Using a multilevel approach, regression analysis of teacher reports indicated that the program had a positive effect on the social climate in the classroom, reduced bullying and improved academic skills. Analysis of children's reports found no significant overall effects. The results were not influenced by students' sex or socioeconomic status

  Social learning theory postulates that self-efficacy is learned through the person's interaction with his/her physical and social environment. In this genetically informative, population-based, multi-informant study of 1,394 adolescent twin pairs, self-efficacy was modeled as one latent psychometric self-efficacy factor with genetic and environmental effects common to all informants, as well as for effects specific for each informant. The results showed that 75% of variation in self-efficacy was due to genetic factors. Non-shared environmental causes explained the remaining 25% of the variance in the latent factor, with no effect of common environment. Some informant-specific effects were also found. The present study challenges the theoretical assumption of learning as the dominant etiological factor behind self-efficacy in young people.

  Abstract: The objective of this study was to assess trauma-related symptoms and mental health among war-exposed Ugandan adolescents (n = 81) as a basis for planning their re-attendance at school. Self-reports of exposure to traumatic events, trauma-related symptoms, and indicators of mental health were collected. While about half of the youths (51.9%) reported having been abducted by rebels and were former child soldiers, no differences were found in their mental health functioning compared to the remaining sample. Of the youths, 78% reported post-traumatic stress reactions of clinical significance. However, scores were within the normal range on conduct problems, hyperactivity, pro-social behavior, and self-efficacy. Even though the sample was clearly suffering from trauma-related symptoms, there were also marked areas of adaptive functioning and resilience. Whether the students are ready for education is discussed and implications for adapting educational programs for war-affected adolescents are indicated.

  Loneliness is prevalent in adolescence, despite the widespread expectation directed to young people to start building close relationships beyond the nuclear family. The aim of the present study was to explore the causal genetic and environmental structure behind variability in adolescents' perceived loneliness. Seven national cohorts (ages 12–18 years) of Norwegian twins reared together (1,394 twin pairs) participated. Perceived loneliness was measured with five items from the UCLA Loneliness Scale. Data were collected from mothers, fathers, and twins' self ratings by means of a posted questionnaire. Biometric analyses were applied, testing the causal architecture of loneliness within a psychometric model with one common latent factor in addition to specific genetic and environmental sources influencing the scores of each informant. The results showed a heritability (h2) of 75% on the latent perceived loneliness factor, and nonshared environmental effects (e2) explaining the remaining 25% of the latent factor variance. There were also significant rater-specific genetic and nonshared environmental effects. No shared environmental effects were found in the model, and there were no sex differences in the estimates. This study showed that variation in perceived loneliness in adolescents is highly genetic. Additional genetic and nonshared environmental etiological sources are to some extent represented in the scores of the specific rater.

  The aim of this multi-informant twin study was to determine the relative role of genetic and environmental factors in explaining variation in trait resilience in adolescents. Participants were consenting families (N = 2,638 twins in 1,394 families), from seven national cohorts (age 12-18 years, both sexes) of monozygotic and dizygotic twins reared together. Questionnaire data on the adolescents' Ego-resilience (ER89) was collected from mothers, fathers and twins, and analysed by means of multivariate genetic modelling. Variance in trait resilience was best represented in an ADE common pathways model with sex limitation. Variance in the latent psychometric resilience factor was largely explained by additive genetic factors (77% in boys, 70% in girls), with the remaining variance (23 and 30%) attributable to non-shared environmental factors. Additive genetic sources explained more than 50% of the informant specific variation in mothers and fathers scores. In twins, additive and non-additive genetic factors together explained 40% and non-shared environmental factor the remaining 60% of variation. In the mothers' scores, the additive genetic effect was larger for boys than for girls. The non-additive genetic factor found in the twins' self ratings was larger in boys than in girls. The remaining sex differences in the specific factors were small. Trait resilience is largely genetically determined. Estimates based on several informants rather than single informants approaches are recommended

  The purpose of this study was to evaluate Zippy’s Friends, a universal school programme that aims at strengthening children’s coping skills. The sample consisted of 1483 children (aged 7–8 years) from 91 second-grade classes in 35 schools. The schools were matched and randomly assigned to intervention or control conditions. Coping was assessed by the Kidcope checklist for children and an adapted version for parents. Parents and teachers reported mental health outcomes using the Strengths and Difficulties Questionnaire. Controlling for the hierarchical structure of the data, latent variable regression analysis indicated that the programme had a significant positive effect on coping and on the impact of mental health difficulties in daily life. Subgroup analyses suggested that coping was improved in girls and children from the low socio-economic subgroup, whereas the impact of mental health difficulties was reduced in boys

  The purposes of this study were to explore the structure of coping with everyday stressors in a young nonclinical population and examine the relationship between coping and mental health. A total of 1324 children from 91 second-grade classes in 35 schools participated. Mental health was assessed using the parent and teacher forms of the Strengths and Difficulties Questionnaire (Goodman, 1997), and coping was assessed by the Kidcope (Spirito et al., 1988) self-report checklist. Exploratory and confirmatory factor analyses suggested a three-factor structure of coping. Latent-variable regression analysis indicated that coping categories including both active and emotional strategies were associated with fewer mental health problems, whereas withdrawal and oppositional coping strategies were associated with greater mental health problems. With some important exceptions, the results replicated previous studies of adults and adolescents. The need for new, more comprehensive coping assessments is highlighted.

  Low informant agreement is of particular concern in clinical settings, since diagnoses and interventions are largely based on reports from parents and/or youths. This study explores youth-parent consistencies in an at-risk sample of youths (n= 42), several from immigrant and refugee families, all with stressful background experiences. Data from a community sample (n= 165) was used to contrast the clinical results. Results showed that correlations between clinical youths and parents were within the same range as those in the community sample. Consistencies concerning absolute level of behavior were higher in the clinical sample. However, interesting differences in informant consistencies were found on difficulties and resources between the two samples. This study adds to the picture that there is no simple relationship between severity of behavior deviance and informant agreement. Asking about behavioral resources as well as difficulties may provide valuable additional information regarding differences in the perspectives of at-risk youths and parents.

  Resilience handler om barnets evne til å klare seg på tross av at det har gjennomlevd sterke belastninger som krig, katastrofer og vanskelige oppveksvilkår. Resilienceforskning viser at de faktorene som kjennetegner barn som klarer seg, blant annet er at de finner noen områder der de kan erfare MESTRING, de har utviklet ulike kreative måter å uttrykke seg på, de henter styrke gjennom FELLESSKAP med jevnaldrene, og ikke minst er de kommet fram til en forståelse av belastningene de har vært gjennom, slik at livet igjen kan oppleves som KONTINUERLIG og meningsfylt. Resiliencegrupper er betegnelsen på den type tiltak som ble utviklet gjennom Resilienceprosjektet ved Nic Waals Institutt 1996 - 1999. Erfaringene fra prosjektet tilsier at tiltaket kan drives med utgangspunkt både i skole, skolehelsetjeneste, ungdomsklubber og fra mer etablerte terapeutiske miljøer som pedagogisk/psykologisk rådgivningstjeneste og barne- og ungdomspsykiatri. Jo mer traumatiserte og belastede deltakerene i en gruppe er, jo viktigere er det imidlertid at fagpersoner med terapeutisk kompetanse er involvert i tiltaket, som veileder og/eller som gruppeledere. Denne håndboken er en veileder i hvordan man kan drive resiliencegrupper. Den inneholder derfor en omfattende gjennomgang av hvordan en resiliencegruppe kan planlegges og gjennomføres.Veiledning betraktes som et vesentlig element i denne typen tiltak, og dette er derfor behandlet i et eget kapittel. Som bakgrunn for intervensjonen gis det en oversikt over resilienceforskning, det vises til teori som kan peke på hvilke prosesser som ligger bak resiliencefaktorene, og traume-/patologiperspektivet drøftes opp mot resilience/salutogenese. Det blir gitt referanser til anbefalt litteratur i tilknytning til hvert av de temaene som behandles i håndboken.

  Hvert år kommer barn til Norge fra krigsområder. Mange av dem har vonde og traumatiske opplevelser knyttet til krig og tap. Første del av videoprogrammet tar for seg hva som er typiske reaksjoner hos barn som følge av krig. Hva er traume? Hva kjennetegner traumatiske opplevelser? Ved å vite litt om disse faktorene er vi bedre rutet til å møte og hjelpe disse barna - enten vi møter dem på skolen, i barnehagen, på barnevernskontoret eller i andre sammenhenger. Siste delen av programmet fokuserer på hvordan vonde opplevelser fra krig og tap kan bli utgangspunkt for mestring. Resilenceforskningen viser at motgang kan være en viktig spire til mestring. Perspektivet er enkelt: Som overlevere av krig har disse barna en del mestringsstrategier med seg når de kommer til Norge. Hvordan kan man bruke dette på en positiv måte slik at barna også blir overlevere av fred? Programmet kan dermed være ett av flere bidrag for å forebygge at denne gruppen faller utenfor og blir mistilpasset. Medvirkende i programmet er sjefspsykolog Helen Christie og spesialpsykolog Trine Waaktaar ved Nic Waals Institutt i Oslo. Programmet er 30 minutter og egner seg som en del av et faglig opplegg på personalmøte eller i andre fora hvor flyktningebarn er tema. De to hoveddelene er på ca. 15 minutter hver.
