Emotion regulation and internalizing symptoms in children with autism spectrum disorders - 2012-01-18T02:26:15-08:00

The aim of this study was to examine the unique contribution of two aspects of emotion regulation (awareness and coping) to the development of internalizing problems in 11-year-old high-functioning children with an autism spectrum disorder (HFASD) and a control group, and the moderating effect of group membership on this. The results revealed overlap between the two groups, but also significant differences, suggesting a more fragmented emotion regulation pattern in children with HFASD, especially related to worry and rumination. Moreover, in children with HFASD, symptoms of depression were unrelated to positive mental coping strategies and the conviction that the emotion experience helps in dealing with the problem, suggesting that a positive approach to the problem and its subsequent emotion experience are less effective in the HFASD group.

A comparison of the trait emotional intelligence profiles of individuals with and without Asperger syndrome - 2012-01-18T02:26:15-08:00

The extent to which the socioemotional impairments of Asperger syndrome (AS) might be extreme manifestations of individual differences within the general population remains under-explored. We compared the trait emotional intelligence (trait EI) profiles of 30 individuals with AS against the profiles of 43 group-matched controls using the Trait Emotional Intelligence Questionnaire (TEIQue). Participants with AS scored significantly lower than controls on 12 of the 15 TEIQue facets (_p ² = 0.09 to 0.49) as well as on all four factors and the global score of the construct (_p ² = 0.07 to 0.41). There was a significant main effect of gender, with men generally scoring higher than women. Results are discussed from the perspective of trait EI theory, with emphasis on its implications for the socioemotional impairments associated with AS.

College students on the autism spectrum: Prevalence and associated problems - 2012-01-18T02:26:15-08:00

As more young people are identified with autism spectrum diagnoses without co-occurring intellectual disability (i.e. high-functioning autism spectrum disorder; HFASD), it is imperative that we begin to study the needs of this population. We sought to gain a preliminary estimate of the scope of the problem and to examine psychiatric risks associated HFASD symptoms in university students. In a large sample (n = 667), we examined prevalence of ASD in students at a single university both diagnostically and dimensionally, and surveyed students on other behavioral and psychiatric problems. Dependent upon the ascertainment method, between .7 per cent and 1.9 per cent of college students could meet criteria for HFASD. Of special interest, none of the students who were found to meet diagnostic criteria (n = 5) formally for HFASD in this study had been previously diagnosed. From a dimensional perspective, those students scoring above the clinical threshold for symptoms of autism (n = 13) self-reported more problems with social anxiety than a matched comparison group of students with lower autism severity scores. In addition, symptoms of HFASD were significantly correlated with symptoms of social anxiety, as well as depression and aggression. Findings demonstrate the importance of screening for autism-related impairment among university students.

Blame and forgiveness judgements among children, adolescents and adults with autism - 2012-01-18T02:26:15-08:00

We compared the capacity of children, adolescents and adults with and without autism to use (a) intent and severity of consequences information for attributing blame to an offender, and (b) intent and apologies information for inferring willingness to forgive. Participants were presented with two sets of six scenarios obtained by combination of intent and severity (or apology) information, and instructed to indicate appropriate levels of blame (or willingness to forgive). In the blame condition, persons with autism were able to consistently use intent information but not to the same degree as their comparison counterparts. In the forgiveness condition, intent was not taken into account for judging by persons with autism, irrespective of their age.

Validation of the Autism Spectrum Screening Questionnaire, Mandarin Chinese Version (CH-ASSQ) in Beijing, China - 2012-01-18T02:26:15-08:00

Background: This study screened children in Beijing, China, in order to establish the validity of a Mandarin Chinese translation of the ASSQ.

Methods: We recruited children diagnosed with autism spectrum disorders (ASDs), attention deficit/hyperactivity disorder (ADHD), childhood-onset schizophrenia (COS) (DSM-IV diagnoses made independently by two senior psychiatrists) and unaffected children attending a public school in Beijing. Their parents were asked to complete the CH-ASSQ.

Results: Data from the parents of 94 children with ASD (mean age: 81 ± 47 months), 45 with ADHD (106 ± 27 months), 26 with COS (166 ± 36 months), and 120 unaffected control (72 ± 16 months) were collected. The total scores of ASSQ in children with ASD, ADHD, COS, and unaffected controls were 25.3 ± 9.2, 10.4 ± 7.1, 12.2 ± 10.6, and 5.2 ± 6.6 respectively. Total ASSQ scores of children with ASD were significantly higher than in any other group (all p < .0001). ROC analysis of ASD versus unaffected control subjects showed the area under curve was 0.957, with a cutoff of 12 having the maximum sensitivity (0.957) and specificity (0.825).

Conclusions: Our pilot data suggest that CH-ASSQ successfully differentiates clinically diagnosed ASD patients from unaffected controls, as well as from patients with ADHD and COS. The instrument might therefore be useful for screening for ASD in urban Mandarin Chinese-speaking populations.

Cerebellar dysfunction, cognitive flexibility and autistic traits in a non-clinical sample - 2012-01-18T02:26:15-08:00

Cerebellar dysfunction and impaired cognitive flexibility are key features of autism spectrum disorders (ASD). However, despite the increasing interest in subclinical autism, no research has yet examined the relationship between these signs and autistic traits in the wider population. This study used the Autism-Spectrum Quotient (AQ) questionnaire to assess autistic traits in university students enrolled in either systems-oriented or humanities degree programmes. Participants also completed a battery of motor tasks designed to assess cerebellar function, and subscales from the Delis–Kaplan Executive Function System (D-KEFS) battery. Students enrolled in systems-oriented degrees had on average higher AQ scores than students enrolled in humanities degrees. The data showed a significant correlation between autistic traits and motor function scores, as well as between autistic traits and verbal set-shifting ability, as assessed on the D-KEFS. These data provide support for the autistic spectrum hypothesis, in indicating that key cognitive, neurological and behavioural features of autism carry over into non-clinical populations.

Minor physical anomalies in children with autism spectrum disorders - 2012-01-18T02:26:15-08:00

Objective: There is clinical heterogeneity among the autism spectrum disorders (ASD). The presence of dysmorphology (minor physical anomalies; MPAs) is one possible tool for defining a clinically relevant subset in ASD. This study employs an adaptation of Miles and Hillman’s (2000) classifications by using photographs to identify a subgroup with significant dysmorphology among children with ASD, typical development (TYP), and developmental delay (DD). Method: Children with ASD, DD, and TYP between 2 and 5 years old were part of the CHARGE Study. Pediatric specialists blinded to diagnostic group classified photographs based on the number of MPAs present: ‘dysmorphic’ if >3 and ‘nondysmorphic’ if <3 MPAs. Results: Photographs for 324 children were included. Significantly more children with ASD were classified as dysmorphic compared to TYP children (p = .007). In children with ASD, seizures were more prevalent in those rated dysmorphic (p = .005). Frequencies were similar between ASD versus DD (p = .19) after removing those with known syndromes. Conclusion: Photographic assessment can be used to detect generalized dysmorphology in children who are often difficult to examine. This has clinical relevance, as children with multiple MPAs can be identified through the use of photographs and prioritized for investigation of brain abnormalities and underlying genetic disorders.
