Titre : Child and Family Characteristics that Predict Autism Spectrum Disorder Specialty Clinic Appointment Attendance and Alignment with Providers Type de document : Texte imprimé et/ou numérique Auteurs : Gazi F. AZAD, Auteur ; V. SINGH, Auteur ; L. KALB, Auteur ; M. PINKETT-DAVIS, Auteur ; R. LANDA, Auteur Article en page(s) : p.3060-3072 Langues : Anglais (eng) Mots-clés : Appointment attendance Autism spectrum disorder Diagnostic alignment Specialty care Index. décimale : PER Périodiques Résumé : We examined factors contributing to initial appointment attendance, alignment between parents' pre-visit and clinicians' diagnostic impressions, and family commitment to follow-ups at an autism spectrum disorder (ASD) specialty clinic. Sample sizes were n = 6558 (initial), n = 1430 (alignment), and n = 1353 (follow-up). Parents completed surveys and clinicians provided their ASD diagnostic impressions. When children were not receiving intervention, families were less likely to keep their initial appointment. Families residing long distances and having older children were less likely to keep their initial and follow-up appointments. African American families were less likely to keep their initial appointment and expressed initial doubts with providers about the diagnosis. Findings suggest that some children are not getting diagnostic clarity or accessing timely services.

Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Female protective effect High-risk siblings Sex differences Index. décimale : PER Périodiques Résumé : Messinger et al. found a 3.18 odds ratio of male to female ASD recurrence in 1241 prospectively followed high-risk (HR) siblings. Among high-risk siblings (with and without ASD), as well as among 583 low-risk controls, girls exhibited higher performance on the Mullen Scales of Early Learning, as well as lower restricted and repetitive behavior severity scores on the Autism Diagnostic Observation Schedule (ADOS) than boys. That is, female-favoring sex differences in developmental performance and autism traits were evident among low-risk and non-ASD high-risk children, as well as those with ASD. Constantino (Mol Autism) suggests that sex differences in categorical ASD outcomes in Messinger et al. should be understood as a female protective effect. We are receptive to Constantino's (Mol Autism) suggestion, and propose that quantitative sex differences in autism-related features are keys to understanding this female protective effect.

We used data from 3031 participants (including 190 ASD cases) from the Environmental Influences on Child Health Outcomes (ECHO) Program to compare distributional properties and criterion validity of 16-item "short" to 65-item "full" SRS scores. Results demonstrated highly overlapping distributions of short and full scores. Both scores separated case from non-case individuals by approximately two standard deviations. ASD prediction was nearly identical for short and full scores (area under the curve values of 0.87, 0.86 respectively). Findings support comparability of shortened and full scores, suggesting opportunities to increase efficiency. Future work should confirm additional psychometric properties of short scores.

Children were enrolled in the Study to Explore Early Development between 2 and 5 years of age. 707 children were classified with ASD after a comprehensive evaluation with strict diagnostic algorithms. Four classes of children with ASD were identified from latent class analysis: mild language delay with cognitive rigidity, mild language and motor delay with dysregulation, general developmental delay, and significant developmental delay with repetitive motor behaviors. We conclude that a four-class phenotypic model of children with ASD best describes our data and improves phenotypic characterization of young children with ASD. Implications for screening, diagnosis, and research are discussed.
