The Autism Spectrum Quotient (AQ) has been developed to measure the degree to which an adult with normal intelligence has autistic traits. In this paper it is evaluated for its potential as a screening questionnaire in clinical practice on one hundred consecutive referrals to a diagnostic clinic for adults suspected of having Asperger Syndrome or high functioning autism (AS/HFA). The results indicate that it has good discriminative validity and good screening properties at a threshold score of 26. The implications of these results are discussed.

To explore associations between psychiatric symptoms and cerebral magnetic resonance imaging abnormalities in low-birth-weight adolescents, 55 very low-birth-weight (<or=1500 gm), 54 term small for gestational age (birth weight <10th centile) and 66 term control adolescents (birth weight >or=10th centile) were assessed at 14-15 years of age. Outcome measures were Schedule for Affective Disorders and Schizophrenia for School-Age Children, Attention-Deficit/Hyperactivity Disorder Rating Scale IV, Autism Spectrum Screening Questionnaire, and qualitatively assessed cerebral magnetic resonance images. The very low-birth-weight group manifested increased prevalence of psychiatric symptoms and disorders compared with controls (P < 0.001), especially symptoms of attention-deficit/hyperactivity disorder, and high frequency of ventricular dilatation, white matter reduction, thinning of corpus callosum, and gliosis (P < 0.01 vs controls). The Attention-Deficit/Hyperactivity Disorder Rating Scale score was significantly associated with white matter reduction and thinning of corpus callosum in this group. The term small for gestational age group had increased prevalence of psychiatric symptoms compared with control subjects, but not more frequent abnormalities on cerebral magnetic resonance imaging. In conclusion, attention-deficit/hyperactivity disorder symptoms were significantly associated with white matter reduction and thinning of corpus callosum in very low-birth-weight adolescents. No associations were found for other psychiatric symptoms and brain abnormalities in any of the groups.

This paper presents an adaptive physical environment that allows children with severe autism to successfully interact with multimodal stimuli, giving them a sense of control of the interaction and, hence, providing them with a sense of agency. This has been an extremely important effort for two main reasons: 1) This user group cannot be typified, hence making the design of an interactive system to fit all the spectrum of individuals a very complex task; 2) each individual PAS (Person on the Autistic Spectrum) user must be able to develop himself within the environment according to his own capacities and potentiality. Qualitative evaluation by psychologists shows very good results and sketches an encouraging future for research on these environments.

At the present time there are a large number of adults who have suspected Asperger syndrome (AS). In this paper we describe a new instrument, the Adult Asperger Assessment (AAA), developed in our clinic for adults with AS. The need for a new instrument relevant to the diagnosis of AS in adulthood arises because existing instruments are designed for use with children. Properties of the AAA include (1) being electronic, data-based, and computer-scorable; (2) linking with two screening instruments [the Autism Spectrum Quotient (AQ) and the Empathy Quotient (EQ)]; and (3) employing a more stringent set of diagnostic criteria than DSM-IV, in order to avoid false positives. The AAA is described, and its use with a series of n = 42 clinic-patients is reported. Thirty-seven of these (88%) met DSM-IV criteria, but only 34 of these (80%) met AAA criteria. The AAA is therefore more conservative than DSM-IV.

Affect regulation (AR) and temperament were examined in children with Autism Spectrum Disorder (ASD). To determine AR, children were exposed to a mildly frustrating situation. Temperament was assessed by the Children's Behavior Questionnaire (CBQ). Children with ASD showed greater variability in AR and used less effective AR strategies compared to controls. Lower academic ability was associated with less effective AR strategies for the ASD while for the controls older age predicted more effective AR strategies. Those with ASD were lower than controls in Attention Focusing, Inhibitory Control, and Soothability. Of the three overarching temperament factors of the CBQ, only Effortful Control but not Negative Affectivity and Surgency/Extraversion distinguished those with ASD from controls. For the ASD group, higher academic ability predicted higher Negative Affectivity. Fewer symptoms and older chronological age predicted higher Effortful Control.

The overall prevalence rates of general and specific child psychiatric disorders in Danish children are unknown. In this study, which aimed to estimate prevalence rates, a multi-method strategy using a two-step design was employed. The first step involved assessment with the Child Behaviour Checklist (CBCL). The second step consisted of assessment using the Schedule for Affective Disorders and Schizophrenia for School-Aged Children; Present and Lifetime version (K-SADS-PL), The Children's Global Assessment Scale (C-GAS), The Wechsler Intelligence Scale for Children (WISCIII), The Autism Spectrum Disorder Screening Questionnaire (ASSQ), and a checklist containing the diagnostic criteria for Pervasive Developmental Disorders (PDD). Non-respondents were assessed through teachers using a modified brief version of the K-SADS-PL. A total of 751 children were targeted. The overall estimated prevalence rate of child psychopathology was 11.8 % [95% confidence interval (CI): 8.8, 14.8]. Attention Deficit/ Hyperactivity Disorder (ADHD) was found to be the most common specific child psychiatric disorder. There was no difference in prevalence rates between respondents and non-respondents. The estimated prevalence rates were broadly comparable to prevalence rates found in other epidemiological studies. The teacher-based interview proved to be a valid instrument for the assessment of non-respondents.

We studied the relationship between patients with attention-deficit/hyperactivity disorder (ADHD) and those with pervasive developmental disorders (PDD), using the High-Functioning Autism Spectrum Screening Questionnaire (ASSQ) and ADHD Rating Scale-IV. The ASSQ scores of the PDD group and the ADHD group were significantly higher than the control group. Furthermore, the PDD group scored higher than the ADHD group. Both groups also showed higher scores than the control group in all three domains, that is, restricted and repetitive behavior, social interaction, and communication problem. The PDD and the ADHD group showed no significant difference in the domains of communication problem, and restricted and repetitive behavior. The PDD group had a higher score than the ADHD group only in the social interaction domain. In total score, inattention score, and hyperactivity/impulsivity score on the ADHD Rating Scale-IV, both groups were significantly higher than the control group. Between the ADHD and the PDD groups, there was no significant difference in the three scores. The patients with strictly diagnosed ADHD had many PDD-related symptoms, and the patients with PDD had many ADHD-related symptoms. It therefore seems difficult to make a distinction between ADHD and PDD by using the present diagnostic criteria in the DSM-IV. We should evaluate each patient in terms of both sets of criteria.

The Autism Spectrum Quotient (AQ) quantifies autistic traits in adults. This paper adapted the AQ for children (age 9.8-15.4 years). Three groups of participants were assessed: Group 1: n=52 adolescents with Asperger Syndrome (AS) or high-functioning autism (HFA); Group 2: n=79 adolescents with classic autism; and Group 3, n=50 controls. The adolescents with AS/HFA did not differ significantly from the adolescents with autism but both clinical groups scored higher than controls. Approximately 90% of the adolescents with AS/HFA and autism scored 30+, vs. none of the controls. Among the controls, boys scored higher than girls. The AQ can rapidly quantify where an adolescent is situated on the continuum from autism to normality.

Autism is a "developmental disorder of neurobiologic origin that is defined on the basis of developmental and behavioral features." Studies over the past 10-15 years suggest that the prevalence of autism is rising. Media coverage has been extensive and has indicated the presence of an "autism epidemic." The goal of this article is to review relevant epidemiologic studies which address the prevalence of Autistic Spectrum Disorders in the last 30 years.

The AQ (Autism-Spectrum Quotient) is a self-administered instrument for measuring the degree to which an adult with normal intelligence has the traits associated with the autistic spectrum. The AQ was administered in Japan to test whether the UK results would generalize to a very different culture. Three groups of subjects, adults with AS or HFA (n = 57), adult controls (n = 194), and University students (n = 1050) were assessed. The adults with AS/HFA had a mean AQ score which was significantly higher than both the controls and the University students. Among the controls, males scored significantly higher than females. The similarity of results in both the general population and the clinical group across the two cultures was remarkable.
