Adaptive behavior profiles in young children with autism spectrum disorder diagnosed under DSM-5 criteria / Rose E. NEVILL in Research in Autism Spectrum Disorders, 43-44 (November 2017)
[article]
Titre : Adaptive behavior profiles in young children with autism spectrum disorder diagnosed under DSM-5 criteria Type de document : Texte imprimé et/ou numérique Auteurs : Rose E. NEVILL, Auteur ; Darren HEDLEY, Auteur ; Mirko ULJAREVIC, Auteur ; Eric BUTTER, Auteur ; James A. MULICK, Auteur Article en page(s) : p.53-66 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Vineland-II Adaptive behavior Subtype Severity Toddlers Early childhood Cluster analysis Index. décimale : PER Périodiques Résumé : AbstractBackground This study explored adaptive behavior profiles in a clinical sample of well-characterized children aged one to three years with ASD. Method Profiles were compared to a sample of children with non-ASD developmental delays. Cluster analyses were performed to determine whether differences in adaptive skills effectively distinguished children with ASD from other young children presenting for assessment due to behavioral or other concerns, but who received other non-ASD diagnoses. Results A profile of motor > daily living > socialization > communication skills was found in both children with ASD and children with non-spectrum diagnoses, showing that this profile is not unique to young children with ASD. A two-group cluster solution was found which differentiated children by developmental functioning level rather than by diagnosis. Discussion The results of this study provide support for two developmental profiles for adaptive functioning in children with ASD: an average to borderline delayed profile and a borderline to more severely delayed profile that may remain stable or worsen over time. They additionally highlight the importance of delivering early targeted interventions to children with ASD who have greater deficits in adaptive functioning due to their association with poorer long-term outcomes.

Titre : ADOS-2 Toddler and Module 1 standardized severity scores as used by community practitioners Type de document : Texte imprimé et/ou numérique Auteurs : Darren HEDLEY, Auteur ; Rose NEVILL, Auteur ; Mirko ULJAREVIC, Auteur ; Eric BUTTER, Auteur ; James A. MULICK, Auteur Article en page(s) : p.84-95 Langues : Anglais (eng) Mots-clés : Autism diagnostic observation schedule Autism spectrum disorder Calibrated severity score Diagnosis Severity Toddler Module Externalizing Internalizing Index. décimale : PER Périodiques Résumé : AbstractBackground The Autism Diagnostic Observation Schedule, 2nd edition (ADOS-2) is a diagnostic instrument which forms part of the recommended “gold standard” for the assessment of Autism Spectrum Disorder (ASD), however raw scores are affected by age, development and language level. Standardized calibrated severity scores (CSS), unlike raw scores, provide a relative metric of the severity of autism-specific symptoms. A CSS has recently been developed for the ADOS-2 Toddler Module, which can be used in children aged 12–30 months. The utility of this new algorithm has yet to be examined in an independent sample, and few studies have examined the ADOS-2 as used by community practitioners, rather than in a research environment. Method Total and domain standardized CSS for the ADOS-2 Toddler Module and Module 1 were examined in an independent, community based sample of 125 young children aged 20–47 months with a diagnosis of ASD, and in a comparison sample of children with nonspectrum diagnoses. Results The CSS was more uniformly distributed when compared to raw scores across age and language groups, and less influenced by participant characteristics, including verbal DQ. Younger non-verbal participants returned higher CSS, suggestive of overlap with developmental and language level. Increased CSS in younger, nonverbal children may also reflect greater severity, thereby leading to earlier referral. The Child Behavior Checklist externalizing score emerged as an independent predictor of ASD symptom severity. Conclusions These results offer tentative support for the introduction of the Toddler Module CSS into community practice; however caution in the interpretation of the score in younger, nonverbal children is urged.

[article]
Titre : An ecological systems model of employee experience in industry-led autism employment programmes Type de document : Texte imprimé et/ou numérique Auteurs : Simon M. BURY, Auteur ; Rosslynn ZULLA, Auteur ; Jennifer R. SPOOR, Auteur ; Rebecca L. FLOWER, Auteur ; David B. NICHOLAS, Auteur ; Darren HEDLEY, Auteur Article en page(s) : p.1457-1470 Langues : Anglais (eng) Mots-clés : autism employment autistic adults ecological systems supported employment Index. décimale : PER Périodiques Résumé : Industry-led employment programmes have emerged to transition autistic people into employment and meet industry labour needs. However, theoretical research is limited in this area, often failing to appreciate the influence of the broader employment ecosystem. In this study, we interviewed 33 autistic employees (n = 29 males, Mage = 29.00?years) from two industry-led employment programmes regarding their experience of the programme?s supports, relationships and impact. We used qualitative content analysis to identify five themes: (1) working involves multiple job tasks that evolve as the employment context changes; (2) workplace relations are diverse and shaped by the type of work and the work environment; (3) workplace needs evolve as autistic individuals navigate the work environment; (4) developing a professional identity in the workplace through mastery and integration; and (5) recommendations for the development of supportive workplace environments for autistic individuals. We describe the way that factors within (e.g. training) and outside the two employment programmes changed and interacted over time to contribute to the participant?s work experience and professional identity. Building on ecological systems theory, our unique contribution to the literature is a new model capturing individual and workplace factors that contribute to the work experience of autistic people who participate in industry employment programmes. Lay Abstract We asked 33 autistic adults from two industry-led employment programmes about their experiences in the programmes. These are programmes started by companies to recruit and support autistic people in work. We also asked about their workplace supports, relationships and how they thought the programme had impacted their life. Understanding the experiences of people in these industry-led employment programmes is important as the information can help to improve the programmes and participants' experiences. After reviewing the interviews, we found five themes that best described the employee?s experience: (1) working involves multiple job tasks that evolve as the employment context changes; (2) relationships in the workplace are diverse and are influenced by the type of work participants do and the work environment; (3) workplace needs change as the autistic employees learn to navigate their work environment; (4) autistic employees develop a professional identity in the workplace as they master work and feel more integrated in the workplace; and (5) recommendations for the development of supportive workplace environments for autistic people. We explored the way that aspects of the two employment programmes (e.g. training) and factors outside the programme changed with time and contributed to the participant?s experience. We developed a new model to capture individual and workplace factors that contribute to the experience of autistic people who participate in industry employment programmes.

Two hundred and fifty-five individuals with ASD (151 males, M(age)?=?33.52 years, SD(age)?=?14.98) took part. More than one-third of participants reported clinically significant anxiety (38.4%) or depression (38%). A slight trend for an increase in the severity of both anxiety and depression from adolescence to middle adulthood, and then a slight decline in older adulthood was found. Female gender and higher ASD severity predicted more anxiety and depression symptoms. Our findings emphasise the need to provide timely assessment and treatment of anxiety and depression in ASD.
