The aim of this pilot study was to explore whether executive functioning (EF) problems of children with severe congenital heart disease (CHD) could be improved through a personalized EF-training program. Eleven preschool-aged children (mean age = 62 months, SD = 6) received a standardized test battery. Eight children were eligible for training and six children participated in the training and posttest.

Objective: Although predictors of the prevalence of behavioral problems in preterm-born children have been frequently studied, predictors of behavioral change in these children remain unknown. Therefore, in this study we explore predictors of short-term changes in problem behavior in preterm-born preschoolers, an age period characterized by rapid behavioral change.

Method: Two- to 5-year-old children born with a gestational age <32 weeks and/or birth weight <1500 g were eligible, because of their high risk for behavioral problems.

Objective: Problems in early development of executive functioning may underlie the vulnerability and individual variability of infants born preterm for behavioral and learning problems. Parenting behaviors may aggravate or temper this increased risk for dysfunction. This study assessed how maternal parenting behaviors predict individual differences in early development of executive functioning in infants born preterm, and whether this varies with infant temperament, i.

In this article, we hypothesize that individuals with autism spectrum disorder (ASD) are born with a deficit in invariance detection, which is a learning process whereby people and animals come to attend the relatively stable patterns or structural regularities in the changing stimulus array. This paper synthesizes a substantial body of research which suggests that a deficit in the domain-general perceptual learning process of invariant detection in ASD can lead to a cascade of consequences in different developmental domains. We will outline how this deficit in invariant detection can cause uncertainty, unpredictability, and a lack of control for individuals with ASD and how varying degrees of impairments in this learning process can account for the heterogeneity of the ASD phenotype.

In order to understand typical and atypical developmental trajectories it is important to assess how strengths or weaknesses in one domain may be affecting performance in other domains. This study examined longitudinal relations between early fine motor functioning, visuospatial cognition, exploration, and language development in preschool children with ASD and children with other developmental delays/disorders. The ASD group included 63 children at T1 (Mage = 27.

Background: Preterm-born or asphyxiated term-born children show more emotional and behavioral problems at preschool age than term-born children without a medical condition. It is uncertain whether parenting intervention programs aimed at the general population, are effective in this specific group. In earlier findings from the present trial, Primary Care Triple P was not effective in reducing parent-reported child behavioral problems.

The present study examined whether atypical visual processing is related to the level of social skills in children with autism spectrum disorder (ASD). Thirty-eight young children with ASD (29 boys, 9 girls) were included. Atypical visual processing was assessed by coding the number of lateral glances and the amount of object grouping behavior on videotaped observations of the ADOS (aged 35 ± 9 months).

Background: Preterm-born or asphyxiated term-born children who received neonatal intensive care show more emotional and behavioral problems than term-born children without a medical condition. It is uncertain whether regular parenting intervention programs to which the parents of these children are usually referred, are effective in reducing child problem behavior in this specific population. Our objective was to investigate whether a regular, brief parenting intervention, Primary Care Triple P, is effective in decreasing emotional and behavioral problems in preterm-born or asphyxiated term-born preschoolers.

Background: With improved medical outcome in preterm infants, the psychosocial situation of their families is receiving increasing attention. For parents, the birth of a preterm infant is generally regarded as a stressful experience, and therefore many interventions are based on reducing parental stress. Nevertheless, it remains unclear whether parents of children born preterm experience more stress than parents of term-born children, which would justify these interventions.

Because early executive functioning is a potentially important predictor of developmental delay and learning difficulties in infants born preterm, this study assessed the effect of several perinatal predictors on the development of A-not-B performance between 7 and 14 months corrected age in 76 infants born preterm, and its relationship to subsequent global cognitive functioning. Latent Growth Modeling showed that gestational age was a predictor of initial level, and that birth weight and gender were predictors of the rate of developmental change in A-not-B performance. Moreover, initial level and rate of developmental change in A-not-B performance were predictive of global cognitive functioning.

Relations among externalizing behavior, therapeutic context (community care vs. residential care), and social problem-solving by children with mild intellectual disabilities or borderline intelligence were examined. Participants were 186 children (12 to 14 years of age) who responded to a video-based social problem-solving task.

A potential mechanism that can explain preterm children's heightened risk for the development of later cognitive and behavioral problems is attention. Attention is the ability of an infant or child to orient to, to shift between and to maintain focus on events, objects, tasks, and problems in the external world, processes which are all dependent on the functioning of attentional networks in the brain. The aim of this paper is to provide a review of the literature on attention development in children born preterm during the first 4 years of life.

Purpose: The objective was to validate the Dutch translation of the Canadian Giving Youth a Voice Questionnaire (GYV-20) for use in paediatric rehabilitation settings in The Netherlands. The GYV-20 consists of 20 items (assessing four domains) and was designed to evaluate the client-centredness of rehabilitation services from an adolescent perspective.

Method: The construct validity, concurrent validity, and reliability of the Dutch GYV-20 were determined.

Objective: In the present study we aim to assess the reliability and validity of the 20-item version of the Dutch Measure of Processes of Care (MPOC).

Design: The reliability, concurrent validity, predictive validity and construct validity of the Dutch MPOC-20 were determined. A subset of MPOC-20 data was extracted from a large Dutch MPOC (56-item version) database.

Objective: To validate the Dutch translation of the Canadian Measure of Processes of Care for Service Providers questionnaire (MPOC-SP) for use in paediatric rehabilitation settings in the Netherlands.

Design: The construct validity, content validity, face validity, and reliability of the Dutch MPOC-SP were determined.

Subjects: The 163 service providers that participated in the validation study represented seven children's rehabilitation centres and affiliated schools in the Netherlands (overall response rate 55.

This study presents a comprehensive evaluation of therapeutic motor interventions for children with or at risk for cerebral palsy (CP), examining 50 studies covering the period from 1990 to 2001. The purpose was to review noticeable changes in the scientific quality of the studies and to highlight trends and changes in the nature of the evaluated programmes. Our results were compared with those of Vermeer and Bakx (1990) who reviewed the period from 1980 to 1989.
