Do toddlers' levels of cortisol and the perceptions of parents and professional caregivers tell the same story about transition from home to childcare? A mixed method study.

Introduction: Enrolling in childcare represents the first transition in toddlers' lives and lays the foundation for their well-being in childcare centers going forward. Child cortisol levels may be an indicator of how toddlers themselves experience their introduction to childcare. In the present study, we explored changes in toddler cortisol levels during their first month in childcare and at a 3-month follow-up, as well as the perceptions of parents and professional caregivers regarding the toddlers' settling-in process during the same period.

Change in toddlers' cortisol activity during a year in childcare. Associations with childcare quality, child temperament, well-being and maternal education.

Elevated levels of the stress hormone cortisol have been found in toddlers in childcare. Measuring cortisol may provide an indication of children's experiences in childcare and help to adjust practices better to their needs. To the best of our knowledge, toddlers' cortisol levels in childcare have not yet been investigated longitudinally.

The Association Between Toddlers' Temperament and Well-Being in Norwegian Early Childhood Education and Care, and the Moderating Effect of Center-Based Daycare Process Quality.

Children who experience well-being are engaging more confidently and positively with their caregiver(s) and peers, which helps them to profit more from available learning opportunities and support current and later life outcomes. The goodness-of-fit theory suggests that children's well-being might be a result of the interplay between their temperament and the environment. However, there is a lack of studies that examined the association between children's temperament and well-being in early childhood education and care (ECEC), and whether this association is affected by ECEC process quality.

Validation of the Leiden Inventory for the Child's Well-Being in Daycare (LICW-D) Questionnaire in Norwegian Early Childhood Education and Care Centers.

The promotion of children's development and well-being is a core concept in Early Childhood Education and Care (ECEC) quality frameworks. Yet, few validated instruments measuring young children's well-being exist. This study examined the validity of The Leiden Inventory for the Child's Well-being in Daycare (LICW-D) (De Schipper et al.

Promoting the Quality of Teacher-Toddler Interactions: A Randomized Controlled Trial of "Thrive by Three" In-Service Professional Development in 187 Norwegian Toddler Classrooms.

The effectiveness of the Thrive by Three intervention, a 10-month, multicomponent, in-service professional development model to promote the quality of caregiver-toddler interactions (i.e., process quality), was tested utilizing a clustered randomized controlled design.

Mediating Mechanisms of the Incredible Years Teacher Classroom Management Program.

This study examined whether, and the extent to which, the Incredible Years Teacher Classroom Management program predicted positive development of children's emotional, behavioral, and social adjustment through changes in the child-teacher relationship. Using data from a longitudinal quasi-experimental intervention trial with a matched control condition, including 1,085 children (49.7% girls, mean = 4.

A Model of Intervention and Implementation of Quality Building and Quality Control in Childcare Centers to Strengthen the Mental Health and Development of 1-3-Year Olds: Protocol for a Randomized Controlled Trial of Thrive by Three.

Background: Universal, high-quality childcare offers a unique opportunity to prevent developmental trajectories leading to mental health problems. Yet, growing evidence has shown that the process quality of Norwegian childcare centers varies considerably, and that research-based models for quality building are significantly lacking.

Objective: To examine whether a model for quality building in childcare centers, Thrive by Three, increases the quality of child-caregiver interactions, and promotes child development, well-being, and mental health.

Does the Incredible Years Teacher Classroom Management programme improve child-teacher relationships in childcare centres? A 1-year universal intervention in a Norwegian community sample.

The Incredible Years Teacher Classroom Management (IY TCM) programme has shown promise in reducing behaviour problems among high-risk children in childcare. However, at present, we do not know whether the IY TCM successfully improves the child-teacher relationship in childcare and whether the effects manifest in both the population and in high-risk groups. Hence, we conducted a quasi-experimental pre-post study with a matched control condition to examine the changes in child-teacher relationships in a sample of 1085 children aged 3-6 years after implementing the IY TCM programme.

Screening for mental health problems in a Norwegian preschool population. A validation of the ages and stages questionnaire: Social-emotional (ASQ:SE).

Background: Early detection of mental health problems in childhood is important. However, studies on screening instruments for preschool children are rare. The aim of this study was to validate the Ages and Stages Questionnaire: Social-Emotional (ASQ:SE) with teacher reports and examine its screening accuracy in a preschool population.

Does the Incredible Years Teacher Classroom Management Training programme have positive effects for young children exhibiting severe externalizing problems in school?: a quasi-experimental pre-post study.

Background: Young children exhibiting severe externalizing problems in school are at risk of developing several poor outcomes. School-based intervention programs have been found to be effective for students with different problems, including those with behavioral problems, emotional distress, or social problems. The present study investigated whether the IY-TCM programme, as a universal stand-alone school intervention programme, reduced severe child externalizing problems as reported by the teacher, and evaluated if these children improved their social competence, internalizing problems, academic performances and student- teacher relationship as a result of the IY TCM training.

Video feedback compared to treatment as usual in families with parent-child interactions problems: a randomized controlled trial.

Background: For the first time to our knowledge, short- and long-term effects of a multi-site randomized-controlled trial (RCT) of video feedback of infant-parent interaction (VIPI) intervention in naturalistic settings are published. The intervention targets families with children younger than 2 years old and parent-child interactions problems. Outcome variables were 1) observed parent-child interactions and 2) parent-reported child social and emotional development.

Symptom changes of oppositional defiant disorder after treatment with the Incredible Years Program.

Objective: To examine changes in symptoms of oppositional defiant disorder (ODD) after treatment with the Incredible Years Program. The frequency of symptoms was also calculated.

Method: The participants were 84 children (aged 4.

International epidemiology of child and adolescent psychopathology ii: integration and applications of dimensional findings from 44 societies.

Objective: To build on Achenbach, Rescorla, and Ivanova (2012) by (a) reporting new international findings for parent, teacher, and self-ratings on the Child Behavior Checklist, Youth Self-Report, and Teacher's Report Form; (b) testing the fit of syndrome models to new data from 17 societies, including previously underrepresented regions; (c) testing effects of society, gender, and age in 44 societies by integrating new and previous data; (d) testing cross-society correlations between mean item ratings; (e) describing the construction of multisociety norms; (f) illustrating clinical applications.

Method: Confirmatory factor analyses (CFAs) of parent, teacher, and self-ratings, performed separately for each society; tests of societal, gender, and age effects on dimensional syndrome scales, DSM-oriented scales, Internalizing, Externalizing, and Total Problems scales; tests of agreement between low, medium, and high ratings of problem items across societies.

Results: CFAs supported the tested syndrome models in all societies according to the primary fit index (Root Mean Square Error of Approximation [RMSEA]), but less consistently according to other indices; effect sizes were small-to-medium for societal differences in scale scores, but very small for gender, age, and interactions with society; items received similarly low, medium, or high ratings in different societies; problem scores from 44 societies fit three sets of multisociety norms.

Associations between high levels of conduct problems and co-occurring problems among the youngest boys and girls in schools: a cross-sectional study.

Background: Few studies have focused on conduct problems and co-occurring problems among the youngest children in schools, such as social, internalizing and attention problems. In particular, there is a lack of studies that differentiate between boys and girls in terms of such problems.

Aim: The aim of the current study was to test associations between conduct problems and social, internalizing and attention problems, as well as adaptive school functioning, which was rated by the teachers of boys and girls in grades 1-3.

School competence and emotional/behavioral problems among Norwegian school children as rated by teachers on the Teacher Report Form.

Of 1,409 eligible children aged 6-13 years in grades 1 to 7 who were randomly selected from a national sample of Norwegian schools, 858 participated in the present study (60.9%). The sample was stratified by school centrality, region and size of grade cohort.

Five- to six-year outcome and its prediction for children with ODD/CD treated with parent training.

Background: While short-term effects of parent training (PT) have been extensively evaluated, long-term outcome and present predictors of a diagnosis for children with ODD/CD treated with parent training are very limited.

Method: In the present study, diagnostic status as outcome and predictors of treatment response were examined in a 5-6-year follow-up. Out of 99 children who had been treated in a randomised controlled trial evaluating the effects of The Incredible Years parent training (PT) or combined parent training and child treatment (PT+CT) programme, 54.

Characteristics of young children with persistent conduct problems 1 year after treatment with the Incredible Years program.

In the present study, predictors of persistent conduct problems among children aged 4-8 years were investigated in a randomized controlled trial 1 year after treatment with the Incredible Years parent training program (PT), or combined parent training and child treatment (PT + CT). Data were collected before and after treatment and at a 1-year follow-up. Pre-treatment child characteristics predicting persistent conduct problems in the child at the 1-year follow-up were high levels of internalizing and aggression problems as reported by mothers.

Treatment of oppositional defiant and conduct problems in young Norwegian children : results of a randomized controlled trial.

The efficacy of the Incredible Years parent training and child therapy programs was examined in a randomized controlled study including 127 Norwegian children aged 4-8 years. Children diagnosed with oppositional defiant disorder (ODD) or conduct disorder (CD) were randomized to parent training (PT), parent training combined with child therapy (PT + CT), or a waiting-list control condition (WLC). Assessments were carried out at baseline, posttreatment and at a one-year follow-up using standardized measures and a semi-structured interview.

Childhood disruptive behaviors and family functioning in clinically referred children: are girls different from boys?

Baseline assessments of 4 to 8-year-old children, 26 girls and 101 boys, referred to outpatient treatment for disruptive behaviors, were examined, focusing on possible differences between the functioning of boys and girls and their families. Child variables included diagnostic information, measures of disruptive behaviors, social competence, and independent observations of child behaviors. A variety of family variables, such as information regarding parenting practices, parental stress, and depression were included.

Changes in social competence in young children treated because of conduct problems as viewed by multiple informants.

In the present study changes in social competence were examined in a clinic sample of 127 children aged 4-8. The children were recruited to a controlled treatment study because of conduct problems at home and were randomised to the Incredible Years parent training (PT), combined PT and child therapy (CT) or a waiting-list control-group. Assessments were conducted pre- and post-treatment and at a one-year follow-up by multiple informants (mother, father, teacher and child).

Children aged 4-8 years treated with parent training and child therapy because of conduct problems: generalisation effects to day-care and school settings.

In this study, generalisation effects to day-care/school settings were examined in an outpatient clinic sample of 127 children aged 4-8 years treated because of oppositional conduct problems in the home with parent training (PT) and parent training combined with child therapy (CT) ("Incredible Years"). Before treatment all children scored above the 90th percentile on the Eyberg Child Behavior Inventory (ECBI) for home problems, and met criteria for a possible or a confirmed diagnosis of either an oppositional defiant (ODD) or a conduct (CD) disorder. Further, 83% of the children showed clinical levels of conduct problems both at home and in day-care/school before treatment.
