These social, personal, and communicative impairments become increasingly pronounced with development, and are present regardless of IQ. The Vineland Adaptive Behavior Scales, Second Edition (Vineland?II) is the most commonly used instrument for quantifying these impairments, but minimal clinically important differences (MCIDs) on Vineland?II scores have not been rigorously established in ASD. We pooled data from several consortia/registries (EU?AIMS LEAP study, ABIDE?I, ABIDE?II, INFOR, Simons Simplex Collection and Autism Treatment Network [ATN]) and clinical investigations and trials (Stanford, Yale, Roche) resulting in a data set of over 9,000 individuals with ASD. Two approaches were used to estimate MCIDs: distribution?based methods and anchor?based methods. Distribution?based MCID [d?MCID] estimates included the standard error of the measurement, as well as one?fifth and one?half of the covariate?adjusted standard deviation (both cross?sectionally and longitudinally). Anchor?based MCID [a?MCID] estimates include the slope of linear regression of clinician ratings of severity on the Vineland?II score, the slope of linear regression of clinician ratings of longitudinal improvement category on Vineland?II change, the Vineland?II change score maximally differentiating clinical impressions of minimal versus no improvement, and equipercentile equating. Across strata, the Vineland?II Adaptive Behavior Composite standardized score MCID estimates range from 2.01 to 3.2 for distribution?based methods, and from 2.42 to 3.75 for sample?size?weighted anchor?based methods. Lower Vineland?II standardized score MCID estimates were observed for younger and more cognitively impaired populations. These MCID estimates enable users of Vineland?II to assess both the statistical and clinical significance of any observed change. Autism Res 2018, 11: 270–283. © 2017 International Society for Autism Research, Wiley Periodicals, Inc. Lay Summary The Vineland Adaptive Behavior Scales (2nd edition; Vineland?II) is the most widely used scale for assessing day?to?day “adaptive” skills. Yet, it is unknown how much Vineland?II scores must change for those changes to be regarded as clinically significant. We pooled data from over 9,000 individuals with ASD to show that changes of 2–3.75 points on the Vineland?II Composite score represent the “minimal clinically?important difference.” These estimates will help evaluate the benefits of potential new treatments for ASD.

We examined stability of such skills in children at high familial risk for ASD who either met diagnostic criteria for ASD at age 7 years (HR-ASD, n = 15) or did not (HR-non-ASD, n = 24) and low-risk control children (LR, n = 37), prospectively studied from infancy. For both HR groups, cognitive skills were consistently lower across time than those of LR children. HR-ASD children showed increasing difficulties in adaptive behaviour over time compared to LR children, while the HR-non-ASD children showed no such difficulties. This pattern of change may inform our understanding of developmental profiles of HR siblings beyond core ASD symptoms.

Alexithymia in Adolescents with Autism Spectrum Disorder: Its Relationship to Internalising Difficulties, Sensory Modulation and Social Cognition / Bosiljka MILOSAVLJEVIC in Journal of Autism and Developmental Disorders, 46-4 (April 2016)

The presentation of alexithymia within ASD at younger ages remains unexplored, and was examined in the present study. Alexithymia rates were significantly elevated in ASD (55 %; 31/56 scoring above cut-off) versus non-ASD adolescents (16 %; 5/32 scoring above cut-off). Within individuals with ASD, alexithymia was associated with increased self-reported anxiety, parent-reported emotional difficulties, self-reported sensory processing atypicalities, and poorer emotion recognition, but was not associated with theory of mind ability. Overall, our results suggest that alexithymia is highly prevalent, and has selective cognitive correlates in young people with ASD.

Alterations in electrophysiological indices of perceptual processing and discrimination are associated with co-occurring emotional and behavioural problems in adolescents with autism spectrum disorder / Virginia CARTER LENO in Molecular Autism, 9 (2018)

Index. décimale : PER Périodiques Résumé : Background: Many young people with autism spectrum disorder (ASD) experience emotional and behavioural problems. However, the causes of these co-occurring difficulties are not well understood. Perceptual processing atypicalities are also often reported in individuals with ASD, but how these relate to co-occurring emotional and behavioural problems remains unclear, and few studies have used objective measurement of perceptual processing. Methods: Event-related potentials (ERPs) were recorded in response to both standard and deviant stimuli (which varied in pitch) in an auditory oddball paradigm in adolescents (mean age of 13.56 years, SD = 1.12, range = 11.40-15.70) with ASD (n = 43) with a wide range of IQ (mean IQ of 84.14, SD = 24.24, range 27-129). Response to deviant as compared to standard stimuli (as indexed by the mismatch negativity (MMN)) and response to repeated presentations of standard stimuli (habituation) were measured. Multivariate regression tested the association between neural indices of perceptual processing and co-occurring emotional and behavioural problems. Results: Greater sensitivity to changes in pitch in incoming auditory information (discrimination), as indexed by increased MMN amplitude, was associated with higher levels of parent-rated behaviour problems. MMN amplitude also showed a trend positive correlation with parent-rated sensory hyper-sensitivity. Conversely, greater habituation at the later N2 component was associated with higher levels of emotional problems. Upon more detailed analyses, this appeared to be driven by a selectively greater ERP response to the first (but not the second or third) standard stimuli that followed deviant stimuli. A similar pattern of association was found with other measures of anxiety. All results remained in covariation analyses controlling for age, sex and IQ, although the association between MMN amplitude and behaviour problems became non-significant when controlling for ASD severity. Conclusions: Findings suggest that alterations in mechanisms of perceptual processing and discrimination may be important for understanding co-occurring emotional and behavioural problems in young people with ASD.

Altered theta-beta ratio in infancy associates with family history of ADHD and later ADHD-relevant temperamental traits / Jannath BEGUM-ALI in Journal of Child Psychology and Psychiatry, 63-9 (September 2022)

One new approach to this is prospective studies of infants with an elevated likelihood of developing ADHD. METHODS: We used a prospective design to examine an oscillatory electroencephalography profile that has been widely studied in both children and adults with ADHD - the balance between lower and higher frequencies operationalised as the theta-beta ratio (TBR). In the present study, we examined TBR in 136 10-month-old infants (72 male and 64 female) with/without an elevated likelihood of developing ADHD and/or a comparison disorder (Autism Spectrum Disorder; ASD). RESULTS: Infants with a first-degree relative with ADHD demonstrated lower TBR than infants without a first-degree relative with ADHD. Further, lower TBR at 10months was positively associated with temperament dimensions conceptually related to ADHD at 2years. TBR was not altered in infants with a family history of ASD. CONCLUSIONS: This is the first demonstration that alterations in TBR are present prior to behavioural symptoms of ADHD. However, these alterations manifest differently than those sometimes observed in older children with an ADHD diagnosis. Importantly, altered TBR was not seen in infants at elevated likelihood of developing ASD, suggesting a degree of specificity to ADHD. Taken together, these findings demonstrate that there are brain changes associated with a family history of ADHD observable in the first year of life.
