Patterns of habitual physical activity in children and adolescents with cerebral palsy (GMFCS I-II)
Background: To provide tailored recommendations and interventions for physical activity in children with cerebral palsy, it is important to gain insight not only into the amount and intensity, but also into the temporal pattern of activity. This descriptive study describes postures, bouts, transitions, timepoints, frequency, and type of activity in ambulatory children with Cerebral Palsy (CP) and compare these patterns with typically developing (…
Does Teacher Talk During Shared Reading Predict Child Oral Language Development in Diverse Ecec Settings
This study investigated whether features of teacher talk predicted children’s oral language development in diverse early childhood education and care settings, and whether the potential effects differed due to children’s age or dual language learner (DLL) status. The study included 203 classrooms with 734 children aged between 25 and 59 months at onset, 56.6% of whom were DLLs. Teacher talk during small-group shared readings was recorded in the f…
Construct Validity of the Perceived Stress Scale 4 in a Norwegian Adult ADHD Community Population
Stress is a potential risk factor for other serious health concerns. Studies show an association between Attention‐Deficit/Hyperactivity Disorder (ADHD) and stress due to impairments in emotional regulation and executive functioning that are typical of the disorder. The Perceived Stress Scale (PSS) is among the most widely used measures of perceived stress, and its four‐item version (PSS‐4) lacks validation in Norwegian contexts. This study aims …
Do Criminogenic Needs Matter in Non-Secure Settings? Assessing Change in Dynamic Risk Factors During Therapeutic Residential Care and the Association With Prediction and Recidivism
This study examined changes in dynamic risk factors during non-secure therapeutic residential care (TRC) and their association with recidivism among 313 at-risk adolescents in Norway. Risk was assessed using the Youth Level of Service/Case Management Inventory (YLS/CMI) at intake and post-treatment, and recidivism was tracked over a 1-year period after TRC. Significant reductions in YLS/CMI risk scores were observed during treatment, and both pos…
Promoting classroom quality through professional development
Substantial evidence shows that high-quality early childhood education and care (ECEC) positively affects children's development. However, many ECEC settings do not meet these standards, highlighting the need for professional development (PD) programs for staff. There is limited knowledge about effective PD models from the Nordic context, particularly in areas with large multiethnic, multilingual populations, and low-income families. The OEES stu…
Toddlers’ Cortisol Levels in Childcare and at Home
Research Findings: Measuring toddlers’ cortisol levels both in childcare and at home and their relation to child- and childcare-related factors may help to identify stress-inducing childcare practices and children who are more vulnerable to stress in childcare. Accordingly, toddlers’ (n = 320, 51.2% female, mean age = 26.8 months) cortisol levels in childcare and at home and their relation to childcare quality and child- and family-related factor…
Parental Involvement in Child Anxiety and Depression
Prior research has linked parental factors such as parent psychopathology, family functioning, parenting style, and parental practices to child anxiety and depression. Parents are often involved in interventions for these disorders. However, previous research suggests that this does not always add to the effect of child treatment alone. Furthermore, little research report changes in known parental risk and protective factors. As part of the ECHO-…
Decisions on contact rights after a care order in Norway from 2008 to 2021
Does thrive by three , a quality-building intervention in childcare centres, strengthen children’s language skills
This study examined the effectiveness of the Thrive by Three intervention for 1-to 3-year-old's language development. Data from 78 childcare centres, 187 toddler classrooms, and 1561 children (91.4% native Norwegian) were included. Results revealed that children in the intervention group had slightly steeper language development than those in the control group, but the difference was not statistically significant. Since previous studies find lang…
Criminogenic Risk Assessment Beyond Juvenile Justice
This study evaluated the predictive properties of the Youth Level of Service/Case Management Inventory (YLS/CMI) in 646 Norwegian adolescents (63% males) placed in non-secure, community-based residential care. Using receiver operating characteristics and logistic regression, the study explored the YLS/CMI’s efficacy in predicting various recidivism outcomes across subgroups. The inventory demonstrated to be a significant predictor for all categor…
Does dose matter? Parental attendance in a preventive intervention for anxious and sad children
In this preventive study, attendance in parent sessions has limited effect on parent-reported symptoms of child emotional difficulties
Young Adults with a History of Residential Youth Care
Adults with a history of living in residential youth care (RYC) face elevated risks across various life domains. In this cohort profile paper, we outline the design of a comprehensive follow-up study-the VINGO study-targeting young adults (22-30 years) with a history of living in RYC (T2). We describe the recruitment strategy and present sample characteristics. Data were collected in the baseline study (T1) from 2011 to 2014. At T1, the 400 adole…
Factor structure of the patient health questionnaire-4 in adults with attention-deficit/hyperactivity disorder
This study indicates promising psychometric properties of the PHQ-4 as a measure of anxiety and depressive symptoms in adults with self-reported ADHD who are fluent in Norwegian. The questionnaire's brevity makes it a valuable resource in research and clinical settings. However, more studies are needed to test the instrument in a clinical sample

Adolescents in therapeutic residential care
Despite the growing body of literature examining the complex needs of adolescents in residential care populations, few studies have investigated the specific treatment needs and characteristics of adolescents in therapeutic residential care (TRC).This study aimed to describe and compare risk, need and responsivity factors in a national sample of 737 juveniles (63% males, mean age = 16.2) who displayed serious behavioural problems.The study utilis…
Executive functions mediate the association between ADHD symptoms and anxiety in a clinical adolescent population
The results pinpoint executive dysfunction as an important treatment target for alleviating anxiety in adolescents with impairing ADHD symptoms
Change Over 11–13 Year Periods in Quality of Life, Emotional Problems and Negative Stressful Life Events Among 13–17 Year Old Students
Studies investigating changes in the general population over time concerning adolescent self-reported Quality of life (QoL) are sparse. The aim of this study is to investigate stability and change over more than a decade in self-reported QoL, emotional problems, and negative stressful life-events among students. Three large cross-sectional samples (N = 1032, 4744 and 3826) of 13-17-year-old adolescents attending public school in the Norwegian Cou…
Toddlers’ stress during transition to childcare
In toddlers, the transition from home to childcare might elicit high levels of the stress hormone cortisol. Measuring cortisol may give an indicator for children’s experience and hence, may help improve this transition. We applied linear mixed model analyses to investigate the cortisol levels of 119 toddlers during their transition to childcare across time of day (morning, afternoon, and evening) and phase (accompanied by parents, separated from …
Psychometric properties of the Inventory of Life Quality in children and adolescents in Norwegian Sign Language
The reliability and validity of the ILC-NSL seem promising, especially for the adolescent version, even though the validation was based on a small sample of DHH children and adolescents
Psychometric properties of the Brief Problem Monitor (BPM) in children with internalizing symptoms
Internal consistency was good, and the original three-factor solution of the BPM-P and BPM-T was confirmed based on our sample of school children at-risk for emotional problems. These promising results indicate that the BPM may be a valid short assessment tool for measuring attentional, behavioral, and internalizing problems in children. Trial registration in Clinical Trials: NCT02340637; June 12, 2014
Parental Chronic Illness, Internalizing Problems in Young Adulthood and the Mediating Role of Adolescent Attachment to Parents
Background: Parental chronic illness is associated with an elevated risk for developing social-emotional and behavioral problems in children, in particular internalizing symptoms. This study aimed to investigate the associations between parental chronic illness when participants were adolescents and subsequent internalizing symptoms in young adulthood and whether adolescent attachment to parents or peers mediates these associations. Methods: The …
Perceived Social Support and Symptom Loads of Psychiatric Disorders among Adolescents in Residential Youth Care
Adolescents in residential youth care (RYC) are at high risk for negative psychological and social development outcomes, as they have a high prevalence of mental health problems and perceive less social support than adolescents in the general population. Associations between perceived social support and mental health problems have been investigated, but no in-depth analyses have been published. Such knowledge is crucial to optimize vulnerable ado…
Measuring mothers' representations of their infants
The Working Model of the Child Interview (WMCI) is frequently used to measure parents' representations. Beyond the global categories ( balanced , disengaged , distorted ), the reliability, factor structure, and validity of all the 15 clinical scales have not previously been studied. The WMCI was administered to 152 Norwegian mothers of infants (mean age = 7.3 months) recruited from community well‐baby clinics. Interrater reliability was adequate …
Developmental Course and Risk Factors of Physical Aggression in Late Adolescence
This study examined risk factors of physical aggression during transition from early to late adolescence using a two-wave longitudinal study. Specifically, we examined if risk factors in early adolescence predict physically aggressive behavior starting in late adolescence and why some adolescents desist physical aggressive behavior while others do not. The study sample consisted of 2289 Norwegian adolescents (1235 girls) who participated in the Y…

Perceived social support among adolescents in Residential Youth Care
Social support may be of particular importance for vulnerable adolescents' development and health and can help them to cope with stressful life events. However, knowledge of perceived social support among adolescents in Residential Youth Care (RYC) is sparse. The present study therefore aimed to investigate perceived social support among adolescents in Norwegian RYC ( N = 304, mean age 16.3 years, girls 57.2%), using a short form of the Social Su…
Child exposure to serious life events, Comt, and aggression
Both genetic and environmental factors contribute to individual differences in aggression. Catechol-O-methyltransferase Val158Met (COMT), a common, functional polymorphism, has been implicated in aggression and aggression traits, as have childhood experiences of adversity. It is unknown whether these effects are additive or interactional and, in the case of interaction, whether they conform to a diathesis-stress or differential susceptibility mod…
Changes in BMI-distribution from 1966–69 to 1995–97 in adolescents. The Young-Hunt study, Norway
The aim of this study was to explore changes in the BMI-distribution over time among Norwegian adolescents. Height and weight were measured in standardised ways and BMI computed in 6774 adolescents 14–18 years who participated in the Young-HUNT study, the youth part of the Health-study of Nord-Trondelag County, Norway in 1995–97. The results were compared to data from 8378 adolescents, in the same age group and living in the same geographical reg…
School wellbeing among children in grades 1 - 10
Different factors may determine school wellbeing in boys and girls, but for both genders, factors relevant for lessons may be more important than factors related to recess. Especially in boys, the student-teacher relationship may be of particular importance
Peer victimization as reported by children, teachers, and parents in relation to children's health symptoms
The agreement between children and significant adults in reporting peer victimization was low to moderate, and the associations of reported victimization with the children's self-reported health symptoms varied substantially between informants. It may be useful to assess prospectively the effects of employing different sources of information related to peer victimization
Longitudinal Course of Diagnosed Depression from Ages 15 to 20 in a Community Sample
Associations Between Parental Attachment and Course of Depression Between Adolescence and Young Adulthood
The long-term effects of being bullied or a bully in adolescence on externalizing and internalizing mental health problems in adulthood
BACKGROUND: The aim is to examine associations between bullying involvement in adolescence and mental health problems in adulthood. METHODS: Information on bullying-involvement (being bullied, bully-victim, aggressive toward others) and non-involved was collected from 2464 adolescents in Mid-Norway at mean age 13.7 and again at mean age 14.9. Information about mental health problems and psychosocial functioning was collected about 12 years later …
Associations between parental chronic pain and self-esteem, social competence, and family cohesion in adolescent girls and boys – family linkage data from the Hunt study
The findings indicate that the presence of both maternal and paternal chronic pain could be a potential risk factor for lower levels of individual and family resilience factors reported by girls. Further research on the relationship between parental pain and sex-specific offspring characteristics, including positive resilience factors, is warranted. The study demonstrates the importance of targeting the entire family in chronic pain care

Non-completion of upper secondary school among female and male young adults in an Arctic sociocultural context; the Naahs study
The gender differences found in this study emphasize the need for gender-specific interventions in preventing non-completion of upper secondary school. There is a need to recognize and treat extensive pro-social behaviour and social problems in young females. Young males from remote areas and those who in early adolescence struggle with functional impairment due to mental health problems need early interventions in lower secondary school. Enhanci…
