Titre : Autism Symptoms, Executive Functioning and Academic Progress in Higher Education Students Type de document : Texte imprimé et/ou numérique Auteurs : Renee R. DIJKHUIS, Auteur ; Leo DE SONNEVILLE, Auteur ; Tim ZIERMANS, Auteur ; Wouter STAAL, Auteur ; Hanna SWAAB, Auteur Article en page(s) : p.1353-1363 Langues : Anglais (eng) Mots-clés : Autism Executive functioning Higher education Young adults Index. décimale : PER Périodiques Résumé : Many students with autism spectrum disorders (ASDs) attending higher education drop out prematurely. The predictive value of self-reported daily executive functioning (EF) and (cognitive) performance-based EF (mental flexibility and working memory) for academic progress was evaluated in 54 young adults with ASD (Mage = 22.5, SD = 2.4, 72% male). Regression analyses showed that autism symptom severity explained 12% of variance in academic progress, which was raised to 36% by adding self-reported daily EF, and to 25% by adding performance-based EF. It is suggested that EF is a candidate marker for academic progress in higher education students with ASD and a candidate target for early intervention.

Titre : Formal Thought Disorder and Executive Functioning in Children and Adolescents with Autism Spectrum Disorder: Old Leads and New Avenues Type de document : Texte imprimé et/ou numérique Auteurs : Tim ZIERMANS, Auteur ; Hanna SWAAB, Auteur ; Alexander STOCKMANN, Auteur ; Esther DE BRUIN, Auteur ; Sophie VAN RIJN, Auteur Article en page(s) : p.1756-1768 Langues : Anglais (eng) Mots-clés : ASD High-functioning Thought disorder Executive functioning Working memory Psychosis Index. décimale : PER Périodiques Résumé : Formal thought disorder (FTD) is a disruption in the flow of thought and a common feature in psychotic disorders and autism spectrum disorder (ASD). Executive dysfunction has often been associated with FTD, yet for ASD convincing evidence is lacking. This study investigated FTD and three core executive functions in 50 young children and adolescents with high-functioning ASD and 56 matched controls. Higher overall levels of FTD marked ASD compared to controls. Furthermore, in ASD decreased performance on verbal working memory was correlated with increased FTD ratings and explained a significant amount of variance of objective and subjective FTD. Verbal working memory is currently the most promising target executive function for understanding the development of idiosyncratic thought disorders in ASD.

Titre : Mental health care use of autistic adults: Identifying longitudinal patterns using sequence analysis Type de document : Texte imprimé et/ou numérique Auteurs : Tim ZIERMANS, Auteur ; Iris RAPOPORT, Auteur ; Kim JONKMAN, Auteur ; Hilde M GEURTS, Auteur Article en page(s) : p.1431-1445 Langues : Anglais (eng) Mots-clés : autism spectrum disorders health services interventions pharmacologic psychiatric comorbidity psychosocial/behavioral Index. décimale : PER Périodiques Résumé : To improve mental health care for autistic adults, a better understanding of their real-world intervention use is required. The aim of this study is to investigate individual differences in the intervention trajectories of autistic adults, by examining longitudinal patterns of therapy, counseling, and medication use. Self-reported intervention use of 445 autistic adults (18-87?years) across at least five consecutive measurements (2015-2021) was collected to identify clusters using sequence analysis and hierarchical clustering. Sensitivity analyses and cross-method validation (group-based multivariate trajectory modeling) were used to verify the obtained clusters. Four out of five obtained clusters had sufficient internal consistency and were replicated. These four clusters had distinct intervention trajectories (least intervention, mostly counseling, mostly medication, mixed use) and differed on several demographic variables. Most notably, the "mixed cluster" contained relatively more females and individuals with self-reported co-occurring psychiatric conditions. Many autistic adults used interventions, although they varied in type and duration of intervention use. This reflects the clinical complexity of tailoring intervention approaches and highlights that accessible and multidisciplinary care is essential to adequately support autistic adults. An important next step is to investigate whether available interventions sufficiently support autistic females and those with co-occurring psychiatric conditions.Lay abstract Many autistic adults experience co-occurring mental health problems, which have a negative effect on their well-being and result in increased use of mental health services. To improve mental healthcare for autistic adults, a better understanding is needed of what type of support they use in real life. Clinical guidelines recommend three kinds of mental health interventions: therapy, counseling, and medication. We investigated the use of these types of interventions in a sample of 445 autistic adults (aged 18-87?years) across a 5-to-7-year period. We found evidence for four different patterns of intervention use, or so-called subgroups: (1) least intervention use, (2) mostly counseling, (3) mostly medication, and (4) mixed intervention use. The group with mixed intervention use consisted of relatively more females and individuals with co-occurring psychiatric conditions, especially compared to the subgroup with the least intervention use. It appeared that many, but not all, autistic individuals used mental health services for an extended period. However, there was considerable variability in the type, combination, and duration of intervention use. This means that determining the optimal support for autistic adults is often a complex task, which requires collaboration of clinical experts and autistic individuals themselves, to make informed decisions.
