Behavioral responses to fevers and other medical events in children with and without ASD / Katherine BYRNE in Autism Research, 15-11 (November 2022)  

Public ISBD [article]  inAutism Research > 15-11 (November 2022) . - p.2056-2063 Titre : Behavioral responses to fevers and other medical events in children with and without ASD Type de document : Texte imprimé et/ou numérique Auteurs : Katherine BYRNE, Auteur ; Shuting ZHENG, Auteur ; Somer BISHOP, Auteur ; Juliana BOUCHER, Auteur ; Sheila GHODS, Auteur ; So Hyun KIM, Auteur ; Catherine LORD, Auteur Article en page(s) : p.2056-2063 Langues : Anglais (eng) Mots-clés : Child  Humans  Autism Spectrum Disorder/complications/psychology  Retrospective Studies  Prospective Studies  Emotions  Parents  Fever/complications  autism spectrum disorder  behavioral symptoms  fever  illness behavior Index. décimale : PER Périodiques Résumé : Anecdotal reports and a small number of research studies suggest possible behavioral improvements in children with autism spectrum disorders (ASD) during a fever. However, previous studies rely largely on retrospective reports of this phenomenon. Establishing a robust association between fever and reduction of ASD-related symptoms would promote opportunities for the development of innovative therapeutic interventions for children with ASD. In the current study, prospective data were collected from 141 children with ASD and 103 typically developing (TD) controls using parent responses to an 11-item behavioral survey. Behaviors when no illness was present, during a fever, the week after a fever, and during non-febrile illnesses for TD and ASD children were compared. Profiles of cases in which caregivers reported consistent behavioral improvements during fever are described. Data indicated worsening social, emotional/behavioral, and somatic symptoms during a fever regardless of diagnosis, with children with ASD demonstrating greater worsening of behaviors during a fever than TD children. Only three out of 141 children with ASD demonstrated consistent behavioral improvements during a fever; these children had a range of cognitive and adaptive skills. Children with ASD had stronger negative responses to fever than TD children. These findings contradict previous literature suggesting behavioral improvements for children with ASD. While improvements may occur for some children, it does not appear to be a common phenomenon. Additional research is needed to elucidate the nature of behavioral improvements in the subset of children with ASD who may respond positively to fever.

Naturalistic developmental behavioral interventions demonstrate strong empirical support and frequently utilize caregiver training of intervention strategies. However, our understanding of the mechanisms of change linked to naturalistic developmental behavioral interventions remains limited. Based on retrospective, secondary data analyses from three previously conducted randomized controlled trials of caregiver-mediated naturalistic developmental behavioral interventions, this study examined the direct effect of intervention on caregiver naturalistic developmental behavioral intervention strategy use and how caregiver changes mediate intervention effects on children?s social communication. A total of 419 videos from 229 dyads consisting of autistic children (M = 32.5?months/ages 1-5 years) and caregivers were included in analyses using the masked ratings of the measure of naturalistic developmental behavioral intervention strategy implementation-caregiver changes (MONSI-CC) and brief observation of social communication change (BOSCC-SC). Using longitudinal mediation analyses, we examined the mediation effect of caregiver behavioral changes on children?s outcomes. Results demonstrated a significant intervention effect on changes of caregiver naturalistic developmental behavioral intervention strategy use (MONSI-CC) and of changeds of caregiver strategy use (MONSI-CC) on child social communication change (BOSCC-SC) scores, but no overall total effect of intervention on changes of child social communication (BOSCC-SC). This study demonstrates the mediating role of caregiver behavior on the child intervention response, a first step toward better understanding underlying mechanisms in naturalistic developmental behavioral interventions.Lay Abstract Naturalistic developmental behavioral interventions use behavioral techniques in naturalistic interactions and settings. Naturalistic developmental behavioral interventions also teach caregivers to use strategies to enhance social communication in their children with autism spectrum disorder. Naturalistic developmental behavioral interventions are effective in supporting young autistic children but how naturalistic developmental behavioral interventions work ("underlying mechanisms") is not known yet. Therefore, by applying new instruments to videos already collected from the three previously conducted randomized controlled trials of caregiver-mediated naturalistic developmental behavioral interventions, we examined how caregivers change in their strategy use over the course of intervention and how that relates to changes in social communication in their autistic children. A total of 419 videos from 229 dyads consisting of autistic children (M = 32.5?months/ages 1-5 years) and caregivers were included in analyses using two measures, one for the caregiver behavioral changes (the measure of naturalistic developmental behavioral intervention strategy implementation-caregiver changes [MONSI-CC]), and another for the children?s social communication (the brief observation of social communication change [BOSCC-SC]). We found that naturalistic developmental behavioral interventions were effective in leading to increased mastery of caregiver naturalistic developmental behavioral intervention strategy use, which then affected the changes in child?s social communication skills. However, we found no direct effect of treatment for child social communication skills. This study highlights the mediating role of caregiver behavior on the child intervention response, supporting the importance of involving caregivers as partners in the intervention for young autistic children.

Methods:  Single and combined use of the ADI-R and ADOS algorithms were compared to clinical best estimate diagnoses for 435 children with autism spectrum disorders (ASD), 113 children with nonspectrum disorders, and 47 children with typical development from 12 to 47 months of age. Sequential strategies to reach a diagnostic decision by prioritizing administrations of instruments were also evaluated. Results:  Well-balanced sensitivities and specificities above 80% were obtained for ASD diagnoses using both instruments. Specificities significantly improved when both instruments were used compared to one. Scores that can be used to systematically prioritize administrations of instruments were identified. Conclusions:  The ADI-R and ADOS make independent, additive contributions to more accurate diagnostic decisions for clinicians evaluating toddlers and young preschoolers with ASD.

Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : BACKGROUND: Heterogeneous mental health outcomes during the COVID-19 pandemic are documented in the general population. Such heterogeneity has not been systematically assessed in youth with autism spectrum disorder (ASD) and related neurodevelopmental disorders (NDD). To identify distinct patterns of the pandemic impact and their predictors in ASD/NDD youth, we focused on pandemic-related changes in symptoms and access to services. METHODS: Using a naturalistic observational design, we assessed parent responses on the Coronavirus Health and Impact Survey Initiative (CRISIS) Adapted For Autism and Related neurodevelopmental conditions (AFAR). Cross-sectional AFAR data were aggregated across 14 European and North American sites yielding a clinically well-characterized sample of N=1275 individuals with ASD/NDD (age=11.0?+?3.6 years; n females=277). To identify subgroups with differential outcomes, we applied hierarchical clustering across eleven variables measuring changes in symptoms and access to services. Then, random forest classification assessed the importance of socio-demographics, pre-pandemic service rates, clinical severity of ASD-associated symptoms, and COVID-19 pandemic experiences/environments in predicting the outcome subgroups. RESULTS: Clustering revealed four subgroups. One subgroup-broad symptom worsening only (20%)-included youth with worsening across a range of symptoms but with service disruptions similar to the average of the aggregate sample. The other three subgroups were, relatively, clinically stable but differed in service access: primarily modified services (23%), primarily lost services (6%), and average services/symptom changes (53%). Distinct combinations of a set of pre-pandemic services, pandemic environment (e.g., COVID-19 new cases, restrictions), experiences (e.g., COVID-19 Worries), and age predicted each outcome subgroup. LIMITATIONS: Notable limitations of the study are its cross-sectional nature and focus on the first six months of the pandemic. CONCLUSIONS: Concomitantly assessing variation in changes of symptoms and service access during the first phase of the pandemic revealed differential outcome profiles in ASD/NDD youth. Subgroups were characterized by distinct prediction patterns across a set of pre- and pandemic-related experiences/contexts. Results may inform recovery efforts and preparedness in future crises; they also underscore the critical value of international data-sharing and collaborations to address the needs of those most vulnerable in times of crisis.

Examining the phenotypic heterogeneity of early autism spectrum disorder: subtypes and short-term outcomes / So Hyun KIM in Journal of Child Psychology and Psychiatry, 57-1 (January 2016)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 57-1 (January 2016) . - p.93-102 Titre : Examining the phenotypic heterogeneity of early autism spectrum disorder: subtypes and short-term outcomes Type de document : Texte imprimé et/ou numérique Auteurs : So Hyun KIM, Auteur ; Suzanne MACARI, Auteur ; Judah KOLLER, Auteur ; Katarzyna CHAWARSKA, Auteur Article en page(s) : p.93-102 Langues : Anglais (eng) Mots-clés : ASD  toddlers  diagnosis  clinical outcomes Index. décimale : PER Périodiques Résumé : Background Phenotypic heterogeneity among toddlers presenting with ASD symptoms complicates diagnostic considerations and limits our ability to predict long-term outcomes. To address this concern, we sought to identify more homogeneous subgroups within ASD based on toddlers’ clinical profiles in the second year of life, evaluating diagnostic stability and clinical outcomes within the subgroups 1–2 years later. Methods One hundred toddlers referred for suspected ASD underwent comprehensive assessments at 22 months (SD = 3) and 37 months (SD = 4). At 22 months, they were clustered based on symptom severity, developmental skills, and adaptive functioning. Diagnostic stability and clinical outcomes were evaluated within the clusters. Results Four clusters characterized by distinct clinical profiles at the time of the first diagnosis were identified. Diagnostic stability was excellent in 3 out of 4 clusters (93%–100%) and was lowest in the initially least affected cluster (85%). Autism symptom severity was stable, except for one group where it increased over time (16% of the sample). A large proportion of toddlers showed significant improvements in verbal and communication skills. Only a small group (17%) exhibited very low levels of functioning and limited gains over time. Conclusions Diagnostic stability and developmental progression from the second to third year of life in toddlers with ASD vary depending on their initial early profiles of relative strengths and deficits. Although a small minority of toddlers with more complex clinical presentations may not retain their diagnoses by the age of three, most children continue to exhibit symptoms of autism. Despite limited improvements in symptom severity, many children show significant gains in verbal functioning. Only a small proportion of children (17%) exhibit very limited gains despite intensive intervention. These findings support continued efforts to examine determinants of developmental trajectories including factors mediating and moderating response to treatment.
