Titre : Assessing autistic traits: cross-cultural validation of the social responsiveness scale (SRS) Type de document : Texte imprimé et/ou numérique Auteurs : Sven BÖLTE, Auteur ; Fritz POUSTKA, Auteur ; John N. CONSTANTINO, Auteur Année de publication : 2008 Article en page(s) : p.354-363 Langues : Anglais (eng) Mots-clés : autism PDD psychometrics ADI-R ADOS SCQ TCI CBCL Index. décimale : PER Périodiques Résumé : The Social Responsiveness Scale (SRS) is a quantitative measure of autistic traits in 4- to 18-year-olds, which has been used in behavior-genetic, epidemiological and intervention studies. The US standardization demonstrated a single-factor structure and good to excellent psychometric properties. The cross-cultural validity of the German adaptation of the parent-report SRS in a sample of N=1,436 children and adolescents: 838 typically developing and 527 clinical participants (160 with autism spectrum disorders (ASDs)) was examined. Internal consistency (0.91-0.97), test-retest reliability (0.84-0.97), interrater reliability (0.76 and 0.95) and convergent validity with the Autism Diagnostic Observation Schedule as well as the Autism Diagnostic Interview - Revised and Social Communication Questionnaire (0.35-0.58) were satisfactory to good. The SRS total score discriminated between ASD and other mental disorders. SRS scores proved to be sufficiently independent of general psychopathology. Principal component analyses yielded single-factor solutions for the normative and clinical subsamples. In addition, construct validity was ensured by consistent correlations with the Vineland Adaptive Behavior Scales, the Child Behavior Checklist and the Junior Temperament and Character Inventory. Normative SRS total scores for girls and boys as well as values for ASD were lower in the German sample, while scores for conduct disorder and attention deficit hyperactivity/conduct disorder combined were higher. Generally, cross-cultural validity of the SRS seems to be sufficiently assured for a large European sample. However, some discrepancies regarding SRS normative and clinical raw score distributions, reliability and validity findings are critically discussed.

Titre : Autistic Traits and Autism Spectrum Disorders: The Clinical Validity of Two Measures Presuming a Continuum of Social Communication Skills Type de document : Texte imprimé et/ou numérique Auteurs : Sven BÖLTE, Auteur ; Eva WESTERWALD, Auteur ; Martin HOLTMANN, Auteur ; Christine M. FREITAG, Auteur ; Fritz POUSTKA, Auteur Année de publication : 2011 Article en page(s) : p.66-72 Langues : Anglais (eng) Mots-clés : PDD Assessment Screening Questionnaire Psychometrics Diagnostics Index. décimale : PER Périodiques Résumé : Research indicates that autism is the extreme end of a continuously distributed trait. The Social Responsiveness Scale (SRS) and the Social and Communication Disorders Checklist (SCDC) aim to assess autistic traits. The objective of this study was to compare their clinical validity. The SRS showed sensitivities of .74 to .80 and specificities of .69 to 1.00 for autism. Sensitivities were .85 to .90 and specificities .28 to.82 for the SCDC. Correlations with the ADI-R, ADOS and SCQ were higher for the SRS than for the SCDC. The SCDC seems superior to the SRS to screen for unspecific social and communicative deficits including autism. The SRS appears more suitable than the SCDC in clinical settings and for specific autism screening.

Titre : Brief Report: Emotional Processing in High-Functioning Autism—Physiological Reactivity and Affective Report Type de document : Texte imprimé et/ou numérique Auteurs : Sven BÖLTE, Auteur ; Fritz POUSTKA, Auteur ; Sabine FEINEIS-MATTHEWS, Auteur Année de publication : 2008 Article en page(s) : p.776-781 Langues : Anglais (eng) Mots-clés : IAPS Self-Assessment Manikin Emotion-induction Autonomic-response Index. décimale : PER Périodiques Résumé : This study examined physiological response and affective report in 10 adult individuals with autism and 10 typically developing controls. An emotion induction paradigm using stimuli from the International Affective Picture System was applied. Blood pressure, heart and self-ratings of experienced valence (pleasure), arousal and dominance (control) were assessed during the experiment. Physiological response profiles correlated low to significantly negative between groups. Individuals with autism experienced less arousal when viewing sad pictures but higher arousal while processing neutral stimuli. In addition, they reported more control than the normative group when viewing fearful and sad stimuli. Findings indicate altered physiological reactivity and affective report in autism, which may be related to more general impairments in socio-emotional functioning.

Titre : Brief Report: The Level and Nature of Autistic Intelligence Revisited Type de document : Texte imprimé et/ou numérique Auteurs : Sven BÖLTE, Auteur ; Fritz POUSTKA, Auteur ; Isabel DZIOBEK, Auteur Année de publication : 2009 Article en page(s) : p.678-682 Note générale : Article Open Access Langues : Anglais (eng) Mots-clés : Pervasive-developmental-disorders Child-psychiatry Cognition Testing Psychometrics Index. décimale : PER Périodiques Résumé : Owing to higher performance on the Raven’s Progressive Matrices (RPM) than on the Wechsler Intelligence Scales (WIS), it has recently been argued that intelligence is underestimated in autism. This study examined RPM and WIS IQs in 48 individuals with autism, a mixed clinical (n = 28) and a neurotypical (n = 25) control group. Average RPM IQ was higher than WIS IQ only in the autism group, albeit to a much lesser degree than previously reported and only for individuals with WIS IQs <85. Consequently, and given the importance of reliable multidimensional IQ estimates in autism, the WIS are recommended as first choice IQ measure in high functioning individuals. Additional testing with the RPM might be required in the lower end of the spectrum.

Titre : A Case–Control Study of Personality Style and Psychopathology in Parents of Subjects with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Sven BÖLTE, Auteur ; Susan KNECHT, Auteur ; Fritz POUSTKA, Auteur Année de publication : 2007 Article en page(s) : p.243-250 Langues : Anglais (eng) Mots-clés : Autism Schizophrenia Obsessive–Compulsive-Disorder Mental-Retardation Phenotype Genetics Index. décimale : PER Périodiques Résumé : To probe the specificity of traits that might be conceptualised as the broader phenotype of autism, parents of subjects with autism from simplex and multiplex families as well as parents of subjects with obsessive–compulsive disorders (OCD), early onset schizophrenia (EOS) and mental retardation (MR) were assessed using the Personality Style and Disorder Inventory and the Symptom Checklist-90-Revised. Autism parents’ scores were increased on several subscales (e.g. reserved/schizoid, depression) compared to parents of subjects with OCD, EOS and normative data, but not in comparison to MR parents. Results provide some support for the specificity of the broader phenotype of autism. The burden of raising severely disabled children could not be ruled out as a factor influencing parts of this phenotype.
