Background: Studies have found that presence of challenging behaviours and mental health problems limits employment for people with intellectual disabilities. This study investigates the associations between age, gender, living condition, level of intellectual disability, diagnoses, behaviour, mental health, and employment in adults with…

Childcare providers are vanguards in identifying children at risk for mental health problems. Thus, the aim of the current study was to investigate the accuracy of childcare providers' nominations of children at risk for mental health problems against a well-established comparator, the Caregiver-Teacher Report Form. Findings from the present…

Smith-Magenis syndrome (SMS) is a genetic syndrome most often caused by a deletion on chromosome 17 or more rarely by a mutation in the retinoic acid-induced 1 gene. The aim of this study was to investigate the Developmental Behavior Checklist (DBC) profile of persons with SMS and the associations between behavioural and emotional problems, age,…

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…

In this study, we explored how free play and scaffolding practices in Early Childhood Education and Care (ECEC) related to children's externalising problems both in ECEC and later in school. Furthermore, we aimed to reduce the knowledge gap of whether these relations depended on children's differences in emotional temperament. We used structural…

Smith-Magenis syndrome (SMS) is a rare genetic syndrome. Students with SMS have a neurobehavioural phenotype which has been characterised as challenging for both parents and teachers. Challenging behaviour often has a negative impact on the person's learning ability and is a hindrance in the learning environment. Challenging behaviour also impacts…

This paper presents findings from a survey among Norwegian K-12 teachers (n = 771), addressing their perceived collaboration with parents when students exhibit internalizing or externalizing behaviour. Positive teacher-parent collaboration is important to enhance student learning. However, behaviour difficulties among students may put the…

Objective: Children with ADHD often experience functional impairments across various aspects of daily life. This study addresses the dearth of longitudinal research on functional impairment trajectories from preschool to school age in children with symptoms of ADHD and comorbid disorders. Methods: We investigated the extent to which functional…

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…

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…

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…

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…

Strain theories expect socio-economically disadvantaged students to be overrepresented among perpetrators of school-deviant behavior. Empirical research, however, is inconclusive about the SES-deviance relationship. Recently, strain theorists argued that economic deprivation, rather than a socio-economic status (SES) index is related to…

The aim of the study has been to examine the impact of diagnosed internalising and externalising behavioural problems on educational attainment. We used a fixed-effect model on rich individual longitudinal register data. The sample consisted of five full cohorts of adolescents (N=242,542). The analyses suggest that compared to their healthy peers,…

This study examined the development of social skills across five measurement points from 4th through 7th grade, and the influence of child gender and school-related factors on the level and growth of social skills, in a large sample of normally developing children in Norway (N = 2,076). On average, children's social skills scores increased…
