Factor Structure of the Children’s Behavior Questionnaire in Children with Williams Syndrome

To examine the factor structure of temperament in 5-10-year-olds with Williams syndrome, an exploratory factor analysis was conducted on the responses of parents of 192 children on the children's behavior questionnaire. Four factors were identified. Two corresponded to factors reported for typically developing children: effortful control and extraversion/surgency and two corresponded to the temperament constructs of withdrawal/inhibition and irritability/frustration and activity, observed in typically developing infants. Parents of 109 of the 192 participants also completed the anxiety disorders interview schedule, parent version. Children with an anxiety disorder other than specific phobia differed significantly from children without an anxiety disorder on all factors except extraversion/surgency. Children with attention deficit hyperactivity disorder (ADHD) differed significantly from children without ADHD on effortful control and extraversion/surgency.     

Modification of the Children’s Sleep Habits Questionnaire for Children with Autism Spectrum Disorder

Sleep problems are common in children with autism spectrum disorder (ASD) and adversely impact daytime functioning. Although no questionnaires have been developed to assess sleep in children with ASD, the 33-item Children’s Sleep Habits Questionnaire (CSHQ) is widely used in this population. We examined the factor structure of the CSHQ in 2872 children (age 4–10 years) enrolled in the Autism Treatment Network. A four-factor solution (Sleep Initiation and Duration, Sleep Anxiety/Co-Sleeping, Night Waking/Parasomnias, and Daytime Alertness) with 5–6 items per factor explained 75% of the total variation. Ten items failed to load on any factor. This abbreviated 23-item four-factor version of this measure may be useful when assessing sleep in children with ASD.     

Does Nutritional Intake Differ Between Children with Autism Spectrum Disorders and Children with Typical Development?

Consumption of macro- and micronutrients and food group servings by children with autism spectrum disorders (ASDs; n = 46) and typical development (n = 31) were compared using 3-day diet records. Children with ASDs consumed significantly more vitamin B6 and E and non-dairy protein servings, less calcium, and fewer dairy servings (p < .05). The significantly lower dairy serving intake persisted after controlling for child age and sex and parental dietary restrictions, and excluding children on the gluten-free casein-free (GFCF) diet. Large proportions of children in both groups did not meet national recommendations for daily intake of fiber, calcium, iron, vitamin E, and vitamin D.     

Children’s Depression Inventory in Estonia

The aim of study was to estimate the score of symptoms of depression with the Children’s Depression Inventory (CDI) among Estonian schoolchildren aged 7–13-year-old, according to age and gender differences, and to identify the components in factor analysis characterising self-reported childhood symptoms of depression. The applicability of the CDI in 7-year-old children was also estimated. The number of subjects in the study was 725 (342 girls and 383 boys), and the mean age was 10.2 (SD 1.7). The mean total score of the CDI for the whole sample was 9.96 (SD = 6.3, range 0–39, median 9.0). The mean scores of symptoms of depression among children did not differ by gender or age. There were no significant differences in the CDI mean scores between 7-year-old compared to older schoolchildren in the present study. Factor analysis obtained five factors: anhedonia, ineffectiveness, negative self-esteem, negative mood and interpersonal problems. Significant gender and age differences were found: girls reported more symptoms of anhedonia and negative self-esteem, and boys reported more symptoms of ineffectiveness. Younger children reported more symptoms of anhedonia and ineffectiveness, and older children negative self-esteem. The study serves as baseline data before intervention of the EC project “European Alliance Against Depression”.     

Relationship Between Children’s Sleep and Mental Health in Mothers of Children with and Without Autism

The study employed 90 children with autism spectrum disorders (ASDs) who were matched to 90 typically developing children on age, gender, and ethnicity. Using structural equation modeling, maternal sleep and maternal stress mediated the relationship between children’s sleep and mothers’ mental health for mothers of children with and without ASDs. Mothers of children with ASDs reported more problems related to children’s sleep, their own sleep, greater stress, and poorer mental health; however, children’s sleep and maternal sleep were more closely related to maternal stress for mothers of typically developing children. Implications of these findings and future directions for research are discussed.     

Psychometric Properties of the Spence Children’s Anxiety Scale (SCAS) in Cypriot Children and Adolescents

The Spence Children’s Anxiety Scale (SCAS) is a 38-item self-report questionnaire which measures symptoms of DSM-IV anxiety disorders in children and adolescents. This study examined the psychometric properties of the Greek translation of SCAS in a large community sample of children and adolescents (N = 1,072), aged 12–17 years, in the non-occupied territory of Cyprus. A subsample of these participants was retested 8 weeks after the initial assessment. The SCAS demonstrated high internal consistency (alpha = .92) and test–retest reliability (r = .88). The SCAS total scores correlated significantly with the anxious/depressed subscale of the Youth Self-Report, the Columbia Impairment Scale, and with the emotional subscale of the Strength and Difficulties Questionnaire. Confirmatory factor analyses revealed the same six-factor structure as the original SCAS. The SCAS proved to be a reliable and valid measure of anxiety symptoms in the Cypriot context.     

Comparisons of the Factor Structure and Measurement Invariance of the Spence Children’s Anxiety Scale—Parent Version in Children with Autism Spectrum Disorder and Typically Developing Anxious Children

The Spence Children’s Anxiety Scale—Parent version (SCAS-P) is often used to assess anxiety in children with autism spectrum disorder (ASD), however, little is known about the validity of the tool in this population. The aim of this study was to determine whether the SCAS-P has the same factorial validity in a sample of young people with ASD (n?=?285), compared to a sample of typically developing young people with anxiety disorders (n?=?224). Poor model fit with all of the six hypothesised models precluded invariance testing. Exploratory factor analysis indicated that different anxiety phenomenology characterises the two samples. The findings suggest that cross-group comparisons between ASD and anxious samples based on the SCAS-P scores may not always be appropriate.     

Reliability and Validity of the Spence Children’s Anxiety Scale for Parents in Mainland Chinese Children and Adolescents

This study examined the psychometric properties of the Spence Children’s Anxiety Scale for Parents (SCAS-P) in 1943 father-mother dyads and 1785 students. Results of confirmatory factor analyses for SCAS-P were in favour of the original model with six correlated factors. The internal consistency of SCAS-P was acceptable (α = .63–.91), and the test–retest reliability was acceptable (r = .46–.72). The convergent and divergent validity of SCAS-P was supported by significant correlations with an internalizing subscale to a greater extent than with an externalizing subscale. Congruent validity was supported by significant correlations between father and mother reports (r = .60–.71) and child and parent reports (r = .25–.42). Significant differences between community and clinical samples supported the discriminant validity. Adolescents showed higher anxiety levels than children, and girls showed higher anxiety levels than boys. Our findings suggest that the SCAS-P is a suitable parent instrument to measure child anxiety symptoms in Mainland Chinese children and adolescents.     

Psychometric Properties of the Spence Children’s Anxiety Scale: Parent Report in Children with Autism Spectrum Disorder

Although anxiety is frequently reported in children with autism spectrum disorder (ASD), existing anxiety scales are often psychometrically inappropriate for this population. This study examined the internal structure, reliability, convergent and discriminant validity of the Spence Children’s Anxiety Scale-Parent Report (SCAS-P; Spence 1999) in 238 school-aged children with ASD. While confirmatory factor analysis did not support the original six-correlated-factor structure, structural support as well as acceptable internal consistency and convergent validity was found for Generalized Anxiety, Separation Anxiety, Panic, and Agoraphobia subscales. Use of the SCAS-P in its original form for assessment in children with ASD was not supported. However, four subscales showed viability, and may benefit re-analyses of existing SCAS-P data and future scale adaptations for research and clinical purposes.     

Does WISC-IV Underestimate the Intelligence of Autistic Children?

Wechsler Intelligence Scale for Children (WISC) is widely used to estimate autistic intelligence (Joseph in The neuropsychology of autism. Oxford University Press, Oxford, 2011; Goldstein et al. in Assessment of autism spectrum disorders. Guilford Press, New York, 2008; Mottron in J Autism Dev Disord 34(1):19–27, 2004). However, previous studies suggest that while WISC-III and Raven’s Progressive Matrices (RPM) provide similar estimates of non-autistic intelligence, autistic children perform significantly better on RPM (Dawson et al. in Psychol Sci 18(8):657–662, doi:10.1111/j.1467-9280.2007.01954.x, 2007). The latest WISC version introduces substantial changes in subtests and index scores; thus, we asked whether WISC-IV still underestimates autistic intelligence. Twenty-five autistic and 22 typical children completed WISC-IV and RPM. Autistic children’s RPM scores were significantly higher than their WISC-IV FSIQ, but there was no significant difference in typical children. Further, autistic children showed a distinctively uneven WISC-IV index profile, with a “peak” in the new Perceptual Reasoning Index. In spite of major changes, WISC-IV FSIQ continues to underestimate autistic intelligence.     

Children’s reactions to parental and sibling death

A signi.cant population of children will experience bereavement because of the death of a parent or a sibling. This grief is different from the bereavement seen in adults and needs to be understood in a developmental context. Cognitive and emotional understanding of death and dying in children gradually evolves with age. This report provides clinicians with information regarding the unique developmental elements in children that relate to the process of bereavement secondary to parental and sibling loss, risk factors for complicated grief, the warning signs of depression and anxiety beyond normal grief reaction, and the guidelines for intervention in children.     

Joint Attention in Parent–Child Dyads Involving Children with Selective Mutism: A Comparison Between Anxious and Typically Developing Children

Although joint attention processes are known to play an important role in adaptive social behavior in typical development, we know little about these processes in clinical child populations. We compared early school age children with selective mutism (SM; n = 19) versus mixed anxiety (MA; n = 18) and community controls (CC; n = 26) on joint attention measures coded from direct observations with their parent during an unstructured free play task and two structured tasks. As predicted, the SM dyads established significantly fewer episodes of joint attention through parental initiation acts than the MA and CC dyads during the structured tasks. Findings suggest that children with SM may withdraw from their parents during stressful situations, thus missing out on opportunities for learning other coping skills. We discuss the implications of the present findings for understanding the maintenance and treatment of SM.     

Does Language Guide Behavior in Children with Autism?

It is unknown if children with high-functioning autism (HFA) employ self-directed speech to guide motor sequencing and motor control, or if they can benefit from using self-directed speech when prompted to do so. Participants performed a three-movement sequence across three conditions: Natural Learning, Task-Congruent Verbalization (TCV), and Task-Incongruent Verbalization (TIV). TIV deleteriously impacted performance in the typically-developing group (n = 22), and not the HFA group (n = 21). TCV improved performance in both groups, but to a greater extent in the HFA group. These findings suggest that children with HFA do not initiate self-directed speech spontaneously, but can use language to guide behavior when prompted to do so.     

Children’s Depression Screener (ChilD-S): Development and Validation of a Depression Screening Instrument for Children in Pediatric Care

The aim of the present study was to develop and validate the Children’s Depression Screener (ChilD-S) for use in pediatric care. In two pediatric samples, children aged 9–12 (N_I = 200; N_II = 246) completed an explorative item pool (subsample I) and a revised item pool (subsample II). Diagnostic accuracy of each of the 22 items from the revised pool was evaluated in order to select the best items for the brief instrument ChilD-S. Areas under the curve (AUCs) of the revised item pool and the ChilD-S were compared. A diagnostic interview, the Kinder-DIPS, served as gold standard. For the purpose of screening for depressive disorders in children, the eight-item ChilD-S (AUC = 0.97) performed just as well as the revised 22-item pool (AUC = 0.94). For the ChilD-S the optimal cut-off point of ≥11 yielded a sensitivity of 0.91 and a specificity of 0.89. The ChilD-S shows high potential for depression screening of children in pediatric care.     

Beyond Distance: Children’s School Travel Mode Choice

Background

Long distance is a leading environmental barrier to walking to school and requires long-term, multilevel interventions. Meanwhile, childhood obesity remains highly prevalent, calling for more immediate solutions.

Purpose

The purpose of this study was to examine attitudinal and environmental correlates of walking to the elementary school, controlling for distance.

Methods

Using parental survey data, 601 child pairs with matched home locations and different school travel modes (walking vs. private automobile) were examined, using conditional logistic regressions.

Results

Despite the same/similar objectively measured distance and home location, perceptions of distance, sidewalk and traffic conditions, park presence, and convenience of walking differed between walkers and automobile users. Parental attitudes and children’s preferences were associated with the odds of walking. Safety concerns (traffic danger, stranger danger, and getting lost) were higher among drivers, but only significant in bivariate analyses.

Conclusions

To promote walking to school, route/street improvements appear promising, but parallel educational and promotional efforts may be needed to address perceptual and attitudinal barriers.

     

Working Memory in Early-School-Age Children with Asperger’s Syndrome

Using a battery of working memory span tasks and n-back tasks, this study aimed to explore working memory functions in early-school-age children with Asperger’s syndrome (AS). Twelve children with AS and 29 healthy children matched on age and IQ were recruited. Results showed: (a) children with AS performed better in digit and word recall tasks, but worse in block recall task and variant-visual-patterns test; (b) children with AS took longer time in most conditions of n-back tasks, and showed larger effects of task load. These findings indicated imbalance of working memory development in AS children: they had advantage in the phonological loop storing, but disadvantage in the visuospatial sketchpad storing, and partial deficit in central executive.
