Are Autistic and Alexithymic Traits Distinct? A Factor-Analytic and Network Approach / Hélio Clemente CUVE in Journal of Autism and Developmental Disorders, 52-5 (May 2022)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 52-5 (May 2022) . - p.2019-2034 Titre : Are Autistic and Alexithymic Traits Distinct? A Factor-Analytic and Network Approach Type de document : Texte imprimé et/ou numérique Auteurs : Hélio Clemente CUVE, Auteur ; Jennifer MURPHY, Auteur ; Hannah HOBSON, Auteur ; Eri ICHIJO, Auteur ; Caroline CATMUR, Auteur ; Geoffrey BIRD, Auteur Article en page(s) : p.2019-2034 Langues : Anglais (eng) Mots-clés : Affective Symptoms/diagnosis/psychology  Autism Spectrum Disorder/diagnosis/psychology  Autistic Disorder/diagnosis/psychology  Humans  Phenotype  Alexithymia  Autism  Factor  Network  Separation Index. décimale : PER Périodiques Résumé : Despite the heterogeneity in autism, socioemotional difficulties are often framed as universal. Increasing evidence, however, suggests that socioemotional difficulties may be explained by alexithymia, a distinct yet frequently co-occurring condition. If, as some propose, autistic traits are responsible for socioemotional impairments, then alexithymia may itself be a symptom of autism. We aimed to determine whether alexithymia should be considered a product of autism or regarded as a separate condition. Using factor-analytic and network approaches, we provide evidence that alexithymic and autistic traits are distinct. We argue that: (1) models of socioemotional processing in autism should conceptualise difficulties as intrinsic to alexithymia; and (2) assessment of alexithymia is crucial for diagnosis and personalised interventions.

Autism Biomarkers: Challenges, Pitfalls and Possibilities / George M. ANDERSON in Journal of Autism and Developmental Disorders, 45-4 (April 2015)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 45-4 (April 2015) . - p.1103-1113 Titre : Autism Biomarkers: Challenges, Pitfalls and Possibilities Type de document : Texte imprimé et/ou numérique Auteurs : George M. ANDERSON, Auteur Article en page(s) : p.1103-1113 Langues : Anglais (eng) Mots-clés : Autism  Conceptualization of autism  Biomarker  Mutualism  Emergenesis  Network Index. décimale : PER Périodiques Résumé : Network perspectives, in their emphasis on components and their interactions, might afford the best approach to the complexities of the ASD realm. Categorical approaches are unlikely to be fruitful as one should not expect to find a single or even predominant underlying cause of autism behavior across individuals. It is possible that the complex, highly interactive, heterogeneous and individualistic nature of the autism realm is intractable in terms of identifying clinically useful biomarker tests. It is hopeful from an emergenic perspective that small corrective changes in a single component of a deleterious network/configuration might have large beneficial consequences on developmental trajectories and in later treatment. It is suggested that the relationship between ASD and intellectual disability might be fundamentally different in single-gene versus nonsyndromic ASD. It is strongly stated that available biomarker “tests” for autism/ASD will do more harm than good. Finally, the serotonin–melatonin-oxidative stress-placental intersection might be an especially fruitful area of biological investigation.

Mapping Collaboration Networks in the World of Autism Research / Neal D. GOLDSTEIN in Autism Research, 8-1 (February 2015)  

Public ISBD [article]  inAutism Research > 8-1 (February 2015) . - p.1-8 Titre : Mapping Collaboration Networks in the World of Autism Research Type de document : Texte imprimé et/ou numérique Auteurs : Neal D. GOLDSTEIN, Auteur ; Helen TAGER-FLUSBERG, Auteur ; Brian K. LEE, Auteur Article en page(s) : p.1-8 Langues : Anglais (eng) Mots-clés : autism  collaboration  IMFAR  network  abstract  geocode Index. décimale : PER Périodiques Résumé : In the era of globalization and with the emergence of autism spectrum disorder as a global concern, the landscape of autism research has expanded to encompass much of the world. Here, we seek to provide an overview of the world of autism research, by documenting collaboration underlying the International Meeting for Autism Research (IMFAR), the pre-eminent annual scientific meeting devoted to the presentation of the latest autism research. We analyzed published abstracts presented at IMFAR meetings, between 2008 and 2013, to determine patterns of collaboration. We described collaboration networks on the individual, institutional, and international levels, and visually depicted these results on spatial network maps. Consistent with findings from other scientific disciplines, we found that collaboration is correlated with research productivity. Collaborative hotspots of autism research throughout the years were clustered on the East and West coasts of the U.S., Canada, and northern Europe. In years when conferences were held outside of North America, the proportion of abstracts from Europe and Asia increased. While IMFAR has traditionally been dominated by a large North American presence, greater global representation may be attained by shifting meeting locations to other regions of the world.
