Whether high quantities of center-based care cause behavior problems is a controversial question. Studies using covariate adjustment for selection factors have detected relations between center care and behavior problems, but studies with stronger internal validity less often find such evidence. We examined whether within-child changes in hours in…

Heterogeneous effects from interventions often remain hidden in between-group analyses, risking overgeneralized conclusions of treatment effects. In this exploratory study, we performed latent profile analysis to unveil differential treatment effects among children in The Incredible Years Teacher Classroom Management Programme (IY TCMP). This…

The goal of this prospective longitudinal study was to explore whether co-occurrent internalizing difficulties and aggression in early childhood convey increased risk for later mental health problems in middle childhood. Participants were mothers from the "Norwegian Mother, Father and Child Cohort Study" (MoBa), who provided assessments…

Conflict situations occur in daily life in kindergarten. Often children find solutions by negotiations and compromises, but sometimes they also can use physical force against each other. The focus in this article is kindergarten practitioners' interventions in conflict situations when children use physical force and do not stop when they are told.…

Background: In addition to symptoms of neurodevelopmental disorders, functional impairment is crucial to the determination of clinical significance. The aim of this study was to examine partial validity and usefulness of the Strengths and Difficulties Questionnaire's (SDQ) impact supplement (SDQ impact) in measuring functional impairment in…

The study investigates child social competence a three different measurement levels (overall level, factor level, and item level), in a sample of parents and children participating in interventions towards emerging or present child problem behaviours. Parents of 550 children aged 3-12 (71% boys) evaluated social competence using the Home and…

The experience of having a rare disorder was summarised in a large study as 'falling outside the vast field of knowledge of the professionals'. Parents (31 mothers and 17 fathers) of 32 persons with Smith-Magenis syndrome (SMS) participated in this study. A phenomenological approach was used to analyse the data into topics and themes. Four themes…

Purpose: Early language difficulties are associated with later internalizing problems across different ages and for different aspects of language. The mechanisms behind this association are, however, less understood. In the current study, we investigated longitudinal associations between language difficulties at 5 years and internalizing problems…

Using data from more than 7000 children from the Norwegian Mother, Father and Child (MoBa) study, this study explored the role of school readiness and teacher-child closeness in the early child education and care (ECEC) setting for the prospective academic and social development of children with early externalizing problems. Mother, ECEC teachers,…

Studies have identified concurrent, longitudinal, and bidirectional associations between language difficulties and internalizing problems. This is commonly explained by social exclusion or withdrawal from peers, but underlying mechanisms are not well understood. This study uses sibling data to investigate if the comorbidity between language…

Emerging evidence suggests that prenatal stress does not solely undermine child functioning but increases developmental plasticity to both negative and positive postnatal experiences. Here we test this proposition using the Norwegian Mother and Child Cohort study while implementing an extreme-group (i.e., high vs. low prenatal stress) design (n =…

This longitudinal, population-based study investigated associations between language problems (LP) and emotional and behavioural difficulties (EBD). Parents and teachers gave information about LP and EBD when the children were 7-9 (T1) and 11-13 years old (T2). Self-reports of EBD were included at T2. In line with findings from clinically referred…

In this pilot study, we examined whether a 2-day Emotion-Focused Family Therapy workshop strengthened parental self-efficacy, satisfaction and beliefs regarding their ability to help their children regulate emotions and reduce the children's symptoms of behavioural- or psychological difficulties. Twenty-three caretakers with 17 children (9 boys)…

Introduction: Although the Aberrant Behavior Checklist (ABC) is one of the most widely used behavioral rating scales among people with developmental disabilities, very few studies have examined the factor structure of the non-English versions. Methods: The construct validity of the Norwegian ABC was examined in a clinical sample of children and…

The majority of studies on mental health in deaf and hard-of-hearing (DHH) children report a higher level of mental health problems. Inconsistencies in reports of prevalence of mental health problems have been found to be related to a number of factors such as language skills, cognitive ability, heterogeneous samples as well as validity problems…
