The purpose of this study was to analyze the alpha-amylase (sAA) and cortisol levels in children with Global developmental delay (GDD) before and after dental treatment and its association with the children's behavior during treatment. The morning salivary cortisol levels and activity of sAA of 33 children with GDD were evaluated before and after dental treatment and were compared to 19 healthy children. The behavior of children with GDD during dental care was assessed by the Frankl scale. ⋯ GDD children showed increased levels of sAA (but not cortisol) prior to the dental treatment as compared to the post-treatment phase. GDD children who showed less favorable behavior during dental care had higher levels of sAA and salivary cortisol than GDD children with more favorable behavior, but only the sAA results were significant. In conclusion, GDD children show hyperactivity of the SNS-axis in anticipation of dental treatment which indicates the need for strategies to reduce their anxiety levels before and during dental care.

Although early intensive behavior interventions have been efficient in producing positive behavior outcome in young children with Autism Spectrum Disorder, there is a considerable variety in the children's progress. Research has suggested that parental and treatment factors are likely to affect children's response to treatment. The purpose of the current study was to examine the interrelating factors that impact children's progress, highlighting the influence of parent inclusion in treatment provision captured by parental stress, how faithfully the parents followed the treatment protocols and the intensity of treatment provided at home. ⋯ Variables of treatment progress and potential predictors of child outcome were analyzed in detail and mapped with regard to their relationships drawn from multiple regression analysis. Particularly, the study highlights an association between parental stress and staff treatment fidelity that interferes with decision making in treatment planning and consequently with positive behavior outcome. Such results provide important scientific and clinical information on parental and treatment factors likely to affect a child's response to treatment.

This paper presents the results of the study which examined the effects of carefully designed physical exercise programs on the development of physical fitness in children with ID. The study sample consisted of 42 children with ID and 45 typically developing children. ⋯ The results were analyzed in terms of participation in the exercise program and level of intellectual functioning. While ID children scored significantly lower on fitness tests when compared with typically developing children, the study revealed an association between degree of ID and physical fitness.

The purpose of this study was to explore the relationship between intelligence and visual motor integration skills in 5-year-old children with 22q11-deletion syndrome (22q11DS) (N = 65, 43 females, 22 males; mean age 5.6 years (SD 0.2), range 5.23-5.99 years). Sufficient VMI skills seem a prerequisite for IQ testing. Since problems related to these skills are reported in children with 22q11DS, weak VMI skills may contribute to the lower than average IQ scores commonly reported. ⋯ The results of this study suggest a characteristic neurocognitive phenotype for 5-year olds with 22q11DS. Deficiencies in visual perception and/or processing are negatively correlated with IQ scores, whereas deficiencies in motor skills do not have a relevant negative impact at this age. These findings provide further insight into 22q11DS specific neurocognitive deficiencies.

This study compared mothers and fathers' regulation with respect to 29 children with intellectual disability (ID) and 30 typically developing (TD) children, matched on their mental age (MA), as they solved eight tasks using physical materials and computers. Seven parents' regulatory strategies were coded as they supported their child's identification of the objective, planning, attention, motivation, joint attention, behaviour regulation and evaluation. Children's performance was scored. ⋯ There was a significant interaction effect of medium and children's MA on overall parents' regulation and on their support of identification of objective and of planning. Most parental strategies were negatively linked with ID and TD children's performance in tasks. In both groups, with control for MA, parental support with the identification of the objective, with planning and with attention was negatively linked to the corresponding self-regulatory strategies of the children with each medium; however, parents' joint attention was positively linked with children's joint attention.
