The Autism Impact Measure (AIM): Initial Development of a New Tool for Treatment Outcome Measurement / Stephen M. KANNE in Journal of Autism and Developmental Disorders, 44-1 (January 2014)
[article]
Titre : The Autism Impact Measure (AIM): Initial Development of a New Tool for Treatment Outcome Measurement Type de document : Texte imprimé et/ou numérique Auteurs : Stephen M. KANNE, Auteur ; Micah O. MAZUREK, Auteur ; Darryn SIKORA, Auteur ; Jayne BELLANDO, Auteur ; Lee BRANUM-MARTIN, Auteur ; Benjamin L. HANDEN, Auteur ; Terry KATZ, Auteur ; Brian FREEDMAN, Auteur ; Mary Paige POWELL, Auteur ; Zachary WARREN, Auteur Article en page(s) : p.168-179 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Outcome Treatment Symptoms Impairment Index. décimale : PER Périodiques Résumé : The current study describes the development and psychometric properties of a new measure targeting sensitivity to change of core autism spectrum disorder (ASD) symptoms, the Autism Impact Measure (AIM). The AIM uses a 2-week recall period with items rated on two corresponding 5-point scales (frequency and impact). Psychometric properties were examined using a large sample (n = 440) of children with ASD enrolled in the Autism Treatment Network. The exploratory factor analysis indicated four factors and resulted in a 25-item questionnaire with excellent overall model fit. Test–retest reliability, cross-informant reliability, and convergent validity with other measures of ASD symptoms and overall functioning were strong. The AIM is a reliable and valid measure of frequency and impact of core ASD symptoms.

HUNDLEY, Auteur ; Amy K. WILSON, Auteur ; Zachary WARREN, Auteur ; Alison VEHORN, Auteur ; Claudia M. B. CARVALHO, Auteur ; James R. LUPSKI, Auteur ; Melissa B. RAMOCKI, Auteur Année de publication : 2013 Article en page(s) : p.42-50 Langues : Anglais (eng) Mots-clés : autism MECP2 genetics phenotype social affect overexpression Index. décimale : PER Périodiques Résumé : Alterations in the X-linked gene MECP2 encoding the methyl-CpG-binding protein 2 have been linked to autism spectrum disorders (ASDs). Most recently, data suggest that overexpression of MECP2 may be related to ASD. To better characterize the relevance of MECP2 overexpression to ASD-related behaviors, we compared the core symptoms of ASD in MECP2 duplication syndrome to nonverbal mental age-matched boys with idiopathic ASD. Within the MECP2 duplication group, we further delineated aspects of the behavioral phenotype and also examined how duplication size and gene content corresponded to clinical severity. We compared ten males with MECP2 duplication syndrome (ages 3–10) with a chronological and mental age-matched sample of nine nonverbal males with idiopathic ASD. Our results indicate that boys with MECP2 duplication syndrome share the core behavioral features of ASD (e.g. social affect, restricted/repetitive behaviors). Direct comparisons of ASD profiles revealed that a majority of boys with MECP2 duplication syndrome are similar to idiopathic ASD; they have impairments in social affect (albeit to a lesser degree than idiopathic ASD) and similar severity in restricted/repetitive behaviors. Nonverbal mental age did not correlate with severity of social impairment or repetitive behaviors. Within the MECP2 duplication group, breakpoint size does not predict differences in clinical severity. In addition to social withdrawal and stereotyped behaviors, we also found that hyposensitivity to pain/temperature are part of the behavioral phenotype of MECP2 duplication syndrome. Our results illustrate that overexpression/increased dosage of MECP2 is related to core features of ASD.

SWANSON, Auteur ; Zachary WARREN, Auteur ; Wendy L. STONE, Auteur ; Alison C. VEHORN, Auteur ; Elizabeth DOHRMANN, Auteur ; Quentin HUMBERD, Auteur Article en page(s) : p.555-561 Langues : Anglais (eng) Mots-clés : autism spectrum disorders diagnosis screening Index. décimale : PER Périodiques Résumé : The increased prevalence of autism spectrum disorder and documented benefits of early intensive intervention have created a need for flexible systems for determining eligibility for autism-specific services. This study evaluated the effectiveness of a training program designed to enhance autism spectrum disorder identification and assessment within community pediatric settings across the state. Twenty-seven pediatric providers participated in regional trainings across a 3.5-year period. Trainings provided clinicians with strategies for conducting relatively brief within-practice interactive assessments following positive autism spectrum disorder screenings. Program evaluation was measured approximately 1.5 years following training through (a) clinician self-reports of practice change and (b) blind diagnostic verification of a subset of children assessed. Pediatric providers participating in the training reported significant changes in screening and consultation practices following training, with a reported 85% increase in diagnostic identification of children with autism spectrum disorder within their own practice setting. In addition, substantial agreement (86%–93%) was found between pediatrician diagnostic judgments and independent, comprehensive blinded diagnostic evaluations. Collaborative training methods that allow autism spectrum disorder identification within broader community pediatric settings may help translate enhanced screening initiatives into more effective and efficient diagnosis and treatment.

This study assessed the impact of EBPs on the Modified Checklist for Autism in Toddlers, Revised with Follow-up (M-CHAT-R/F). Participants included 290 children, 18-48 months of age, referred for ASD-related concerns. Those diagnosed with ASD had significantly lower externalizing EBPs compared to those who were not diagnosed with ASD. More externalizing symptoms and younger age were significantly predictive of an M-CHAT-R/F final score. Sensitivity and specificity was impacted by the age of the child. These results suggest that combining measures that assess EBPs and autism core symptoms may improve accuracy in this referred population.
