Autism and schizophrenia in high functioning adults: Behavioral differences and overlap / Annelies A. SPEK in Research in Autism Spectrum Disorders, 4-4 (October-December 2010)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 4-4 (October-December 2010) . - p.709-717 Titre : Autism and schizophrenia in high functioning adults: Behavioral differences and overlap Type de document : texte imprimé Auteurs : Annelies A. SPEK, Auteur ; Saskia G.M. WOUTERS, Auteur Année de publication : 2010 Article en page(s) : p.709-717 Langues : Anglais (eng) Mots-clés : Autism Schizophrenia SPQ AQ Negative-symptoms Social-skill Index. décimale : PER Périodiques Résumé : Several recent studies have demonstrated a genetical overlap between autism and schizophrenia. However, at a behavioral level it remains unclear which features can validly distinguish adults with autism from an adult schizophrenia group. To this end, the present study compared 21 individuals with the autistic disorder and 21 individuals with schizophrenia in self-reported features of autism and schizophrenia, as measured by the Autism-Spectrum Quotient (AQ) and the Schizotypal Personality Questionnaire (SPQ). The schizophrenia group was more likely to report positive symptoms and the adults with autism were more likely to report impairments in social skill. Overlap was found between the two groups in negative symptoms, disorganization, attention to detail and imagination. Thus, when discriminating between the two disorders, especially social skill and the presence of positive symptoms are relevant, whereas the presence of negative symptoms is not indicative.

Clinical assessment of ASD in adults using self- and other-report: Psychometric properties and validity of the Adult Social Behavior Questionnaire (ASBQ) / E.H. HORWITZ in Research in Autism Spectrum Disorders, 24 (April 2016)

Psychometric qualities, convergence between self report and other report ratings, and scores in a group diagnosed with ASD and multiple comparison groups were examined. Principal Component Analyses yielded a structure with six dimensions (reduced contact, reduced empathy, reduced interpersonal insight, violation of social conventions, insistence on sameness, and sensory stimulation/motor stereotypies) for both self- and other-report versions. Reliability estimates and correlations between self- and other-ratings were good and the score profile on the 44-item ASBQ differentiated a group with ASD from a non-clinical group and patients with depression, schizophrenia and ADHD. We conclude that the ASBQ is a short and easy to apply questionnaire that captures the heterogeneous nature of ASD. It yields a score profile among six ASD problem domains both from the perspective of the patient and from a significant other.

Comparing cognitive functioning in schizophrenia and autism using WAIS-III / Marion DE BOER in Research in Autism Spectrum Disorders, 8-7 (July 2014)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 8-7 (July 2014) . - p.737-745 Titre : Comparing cognitive functioning in schizophrenia and autism using WAIS-III Type de document : texte imprimé Auteurs : Marion DE BOER, Auteur ; Annelies A. SPEK, Auteur ; Jill LOBBESTAEL, Auteur Article en page(s) : p.737-745 Langues : Anglais (eng) Mots-clés : Schizophrenia  Autism  Cognitive functioning  WAIS-III  Processing speed Index. décimale : PER Périodiques Résumé : Abstract The main goal of this study was to investigate differences and similarities in general cognitive functioning between adults with schizophrenia and autism, because this has not been systematically investigated. We used a cross-sectional design to compare adults with schizophrenia (n = 27), with autism (n = 114) and a healthy control group (n = 30). Schizophrenia diagnoses were based on the Structured Clinical Interview for the DSM-IV Axis I (SCID-I) and behavioral symptoms were assessed with the Positive and Negative Syndrome Scale (PANSS). Autism was diagnosed with a DSM-IV questionnaire for autism spectrum disorders and the Autistic Diagnostic Interview, revised version. The Wechsler Adult Intelligence Scale, third version (WAIS-III) was used to assess cognitive functions. All participants were between 18 and 65 years of age and had a minimum full scale intelligence of 80. Results showed that patients with schizophrenia scored significantly lower on processing speed than patients with autism and the healthy control group. Differences on other index scales were not found. In participants with schizophrenia a correlation was found between processing speed impairment and negative symptoms. Diagnosis could be predicted correctly with WAIS-III profile in 70.4% of the cases with schizophrenia compared to 56.7% of the healthy control group and 22.8% of the autism group.

The results were compared to a neurotypical group of 30 men and 38 women. The results indicate that men and especially women with ASD experience various eating problems. Women with ASD also recognized symptoms of an eating disorder. Hence, it is important to be aware of eating problems and symptoms of an eating disorder in adults with ASD, to ensure they receive the care they need.

A randomized controlled trial with baseline, post-intervention, and 10-week follow-up, that explores the effects of animal assisted therapy (AAT) was conducted. In total, 53 adults with ASD with normal to high intelligence were randomized in an intervention (N = 27) versus waiting list control group (N = 26). The remarkable adherence to the therapy program by study participants and the program's clinically relevant effects indicate that AAT with dogs can be used to reduce perceived stress and symptoms of agoraphobia, and to improve social awareness and communication in adults with ASD with normal to high intelligence.
