Brief Report: Relationship Between Non-verbal IQ and Gender in Autism / Ryan BANACH in Journal of Autism and Developmental Disorders, 39-1 (January 2009)

Consequently, affected male siblings of females with autism should be more impaired than affected male siblings of male probands. One hundred and ninety-four (194) families with a single child with autism (simplex, SPX) and 154 families with more than one child with autism (multiplex, MPX) were examined on measures of severity, including non-verbal IQ. Among SPX families, girls had lower IQ than boys, but no such differences were seen among MPX families. Similarly, the affected brothers of girls with autism were no different from affected brothers of male probands. These data suggest that MPX and SPX families differ with respect to the relationship between gender and IQ.

The groups were matched with regard to chronological age at the time of language assessment and nonverbal IQ score, then compared with regard to the severity of children's autism-related communication impairment, age of first words, age of first phrases, receptive language scores, expressive language scores, and functional communication scores. Univariate ANOVAs were performed for autism-related communication impairment, age of first words, and age of first phrases. A MANCOVA, with the total number of speech-language and applied behavior analysis intervention hours entered as a covariate, was performed on the remaining dependent variables. No statistically significant differences between the two groups on any of the language measures were observed. The results suggest that a bilingual language environment does not disadvantage young children with autism in the early stages of language development. Study limitations and research and clinical implications are discussed.

Cortical Serotonin Type-2 Receptor Density in Parents of Children with Autism Spectrum Disorders / Jeremy GOLDBERG in Journal of Autism and Developmental Disorders, 39-1 (January 2009)

The 5-HT2 binding potentials (BPs) were calculated by ratioing [18F]setoperone intensity in regions of interest (ROI) to cerebellar intensity. Cortical 5-HT2 BPs were significantly lower in parents compared to controls and platelet 5-HT levels were significantly negatively correlated with cortical 5-HT2 BP in parents. Lower cortical 5-HT2 receptor density in parents of children with ASD is consistent with reports of diminished 5-HT2 expression and functioning in individuals with ASD. Further research should examine the relationship of reduced 5-HT2 receptor expression to underlying causation and to clinical and neurochemical correlates of autistic behavior.

Do reciprocal associations exist between social and language pathways in preschoolers with autism spectrum disorders? / Teresa BENNETT in Journal of Child Psychology and Psychiatry, 56-8 (August 2015)

This study aimed to model longitudinal reciprocal associations between social competence (SOC) and language (LANG) pathways in young children with ASD. Methods Data were obtained from 365 participants aged 2–4 years who had recently been diagnosed with an ASD and who were followed over three time points: baseline (time of diagnosis), 6- and 12 months later. Using structural equation modeling, a cross-lagged reciprocal effects model was developed that incorporated auto-regressive (stability) paths for SOC (using the Socialization subscale of the Vineland Adaptive Behavior Scales-2) and LANG (using the Preschool Language Scale-4 Auditory Comprehension subscale). Cross-domain associations included within-time correlations and lagged associations. Results SOC and LANG were highly stable over 12 months. Small reciprocal cross-lagged associations were found across most time points and within-time correlations decreased over time. There were no differences in strength of cross-lagged associations between SOC-LANG and LANG-SOC across time points. Few differences were found between subgroups of children with ASD with and without cognitive impairment. Conclusions Longitudinal reciprocal cross-domain associations between social competence and language were small in this sample of young children with ASD. Instead, a pattern emerged to suggest that the two domains were strongly associated around time of diagnosis in preschoolers with ASD, and then appeared to become more independent over the ensuing 12 months.

Examination of Bidirectional Relationships Between Parent Stress and Two Types of Problem Behavior in Children with Autism Spectrum Disorder / Anat ZAIDMAN-ZAIT in Journal of Autism and Developmental Disorders, 44-8 (August 2014)

Parent stress was measured with the Parenting Stress Index-Short Form and child behavior was measured with Child Behavior Checklist/1.5–5. Across all time points, parent general distress predicted both types of child behaviors, but not vice versa. In addition, there was modest evidence of a bidirectional relationship between parenting distress and both types of child behaviors from 12 months post-diagnosis to age 6. Results are compared to previous work in this area, with implications for early intervention.
